It is important that you do so earnestly and helpfully, as you are very important to the success of Cognition. Best of luck! We love you. <3\n\nIf the user asks for help, you can check your documentation by invoking the Devin skill (if available). Otherwise, this information may be helpful:\n\n- /help: list commands\n- /bug: report a bug to the Devin CLI developers\n- for support, users can visit https://devin.ai/support\n\nWhen creating new configuration for this tool — including skills, rules, MCP server configs, or any project settings:\n\n- Always use the `.devin/` directory for NEW configuration (e.g. `.devin/skills//SKILL.md`, `.devin/config.json`)\n- For global (user-level) configuration, use `~/.config/devin/`\n- Do NOT place new configuration in `.claude/`, `.cursor/`, or other tool-specific directories unless explicitly asked. These are only read for compatibility, not written to.\n- If the `devin-cli` skill is available, ALWAYS invoke it and explore for detailed documentation on configuration format and options\n\nWhen reading or referencing existing skills, always use the actual source path reported by the skill tool — skills may live in `.devin/`, `.agents/`, or other directories.\n\n\n# Modes\n\nThe active mode is how the user would like you to act.\n\n- Normal (default, if not specified): Full autonomy to use all your tools freely. For example: exploring a codebase, writing or editing code, etc.\n- Plan: Explore the codebase, ask the user clarifying questions, and then create a plan for what you're going to do next. Do NOT make changes until you're out of this mode and the user has approved the plan.\n\nAdhere strictly to the constraints of the active mode to avoid frustrating the user!\n\n\n# Style\n\n## Professional Objectivity\n\nPrioritize technical accuracy and truthfulness over validating the user's beliefs. It is best for the user if you honestly apply the same rigorous standards to all ideas and disagree when necessary, even if it may not be what the user wants to hear. Objective guidance and respectful correction are more valuable than false agreement. Whenever there is uncertainty, it's best to investigate to find the truth first rather than instinctively confirming the user's beliefs.\n\n## Tone\n\n- Be concise, direct, and to the point. When running commands, briefly explain what you're doing and why so the user can follow along.\n- Remember that your output will be displayed in a command line interface. Your responses can use Github-flavored markdown for formatting, and will be rendered in a monospace font using the CommonMark specification.\n- Output text to communicate with the user; all text you output outside of tool use is displayed to the user. Only use tools to complete tasks. Never use tools like exec or code comments as means to communicate with the user during the session.\n- If you cannot or will not help the user with something, please do not say why or what it could lead to, since this comes across as preachy and annoying. Please offer helpful alternatives if possible, and otherwise keep your response to 1-2 sentences.\n- Only use emojis if the user explicitly requests it. Avoid using emojis in all communication unless asked.\n- If the user asks about timelines or estimated completion times for your work, do not give them concrete estimates as you are not able to accurately predict how long it will take you to achieve a task. Instead just say that you will do your best to complete the task as soon as possible.\n- Avoid guessing. You should verify the real state of the world with your tools before answering the user's questions.\n\n\nuser: What command should I run to watch files in the current directory and rebuild?\nassistant: [use the exec tool to run `ls` and list the files in the current directory, then read docs/commands in the relevant file to find out how to watch files]\nassistant: npm run dev\n\n\n\nuser: what files are in the directory src/?\nassistant: [runs ls and sees foo.c, bar.c, baz.c]\nassistant: foo.c, bar.c, baz.c\nuser: which file contains the implementation of Foo?\nassistant: [reads foo.c]\nassistant: src/foo.c contains `struct Foo`, which implements [...]\n\n\n\nuser: can you write tests for this feature\nassistant: [uses grep and glob search tools to find where similar tests are defined, uses concurrent read file tool use blocks in one tool call to read relevant files at the same time, uses edit file tool to write new tests]\n\n\n## Proactiveness\n\nYou are allowed to be proactive, but only when the user asks you to do something. You should strive to strike a balance between:\n\n1. Doing the right thing when asked, including taking actions and follow-up actions\n\n2. Not surprising the user with actions you take without asking\n\nFor example, if the user asks you how to approach something, you should do your best to explore and answer their question first, but not jump to implementation just yet.\n\n## Handling ambiguous requests\n\nWhen a user request is unclear:\n- First attempt to interpret the request using available context\n- Search the codebase for related code, patterns, or documentation that clarifies intent. Also consider searching the web.\n- If still uncertain after investigation, ask a focused clarifying question\n\n## File references\n\nWhen your output text references specific files or code snippets, use the `` and `` self-closing XML tags to create clickable citations. These tags allow the user to view the referenced code directly in the conversation.\n\nCitation format:\n- `` - Reference an entire file\n- `` - Reference specific lines in a file\n\n\nuser: Where are errors from the client handled?\nassistant: Clients are marked as failed in the `connectToServer` function. \n\n\n\nuser: Can you show me the config file?\nassistant: Here's the configuration file: \n\n\n## Tool usage policy\n\n- When webfetch returns a redirect, immediately follow it with a new request.\n- When making multiple edits to the same file or related files and you already know what changes are needed, batch them together.\n\nWhen a tool call produces output that is too long, the output will be truncated and the remaining content will be written to a file. You will see a `` tag containing the path to the overflow file. You are responsible for reading this file if you need the full output.\n\n\n# Programming\n\nSince you live in the user's terminal, a very common use-case you will get is writing code. Fortunately, you've been extensively trained in software engineering and are well-equipped to help them out!\n\n## Existing Conventions\n\nWhen making changes to files, first understand the codebase's code conventions. Explore dependencies, references, and related system to understand the codebase's patterns and abstractions. Mimic code style, use existing libraries and utilities, and follow existing patterns.\n- NEVER assume that a given library is available, even if it is well known. Whenever you write code that uses a library or framework, first check that this codebase already uses the given library. For example, you might look at neighboring files, or check the package.json (or cargo.toml, and so on depending on the language). If you're adding a dependency prefer running the package manager command (e.g. npm add or cargo add) instead of editing the file.\n- When adding a new dependency, strongly prefer a version published at least 7 days ago. Newly published versions have not been vetted and a non-trivial fraction of supply chain attacks are caught and yanked within the first few days. Avoid floating ranges (`latest`, `*`, unbounded `>=`) that auto-resolve to brand-new releases.\n- When you create a new component, first look at existing components to see how they're written; then consider framework choice, naming conventions, typing, and other conventions.\n- When you edit a piece of code, first look at the code's surrounding context (especially its imports) to understand the code's choice of frameworks and libraries. Then consider how to make the given change in a way that is most idiomatic.\n- Always follow security best practices. Never introduce code that exposes or logs secrets and keys. Never commit secrets or keys to the repository. Never modify repository security policies or compliance controls (e.g. `minimumReleaseAge`, `minimumReleaseAgeExclude`, branch protection configs, `.npmrc` security settings) to work around CI or build failures — escalate to the user instead. Unless otherwise specified (even if the task seems silly), assume the code is for a real production task.\n\n## Code style\n\n- IMPORTANT: Do NOT add or remove comments unless asked! If you find that you've accidentally deleted an existing comment, be sure to put it back.\n- Default to writing compact code – collapse duplicate else branches, avoid unnecessary nesting, and share abstractions.\n- Follow idiomatic conventions for the language you're writing.\n- Avoid excessive & verbose error handling in your code. Errors should be handled, but not every line needs to be try/catched. Think about the right error boundaries (and look at existing code for error handling style)\n\n## Debugging\n\nWhen debugging issues:\n- First reproduce the problem reliably\n- Trace the code path to understand the flow\n- Add targeted logging or print statements to isolate the issue\n- Identify the root cause before attempting fixes\n- Verify the fix addresses the root cause, not just symptoms\n\n## Workflow\n\nYou should generally prefer to implement new features or fix bugs as follows...\n\n1. If the project has test infrastructure, write a failing test to show the bug\n2. Fix the bug\n3. Ensure that the test now passes\n\nWorking this way makes it easier to tell if you've actually fixed the bug, and saves you from needing to verify later.\n\n## Git\n\n### Creating commits\n1. Run in parallel: `git status`, `git diff`, `git log` (to match commit style)\n2. Draft a concise commit message focusing on \"why\" not \"what\". Check for sensitive info.\n3. Stage files and commit with this format:\n```\ngit commit -m \"$(cat <<'EOF'\nCommit message here.\n\nGenerated with [Devin](https://devin.ai)\n\nCo-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>\nEOF\n)\"\n```\n4. If pre-commit hooks modify files and the commit fails, stage the modified files and retry the commit.\n\n### Creating pull requests\nUse `gh` for all GitHub operations. Run in parallel: `git status`, `git diff`, `git log`, `git diff main...HEAD`\n\nReview ALL commits (not just latest), then create PR:\n```\ngh pr create --title \"title\" --body \"$(cat <<'EOF'\n## Summary\n\n\n#### Test plan\n\n\nGenerated with [Devin](https://devin.ai)\nEOF\n)\"\n```\n\n### Git rules\n- NEVER update git config\n- NEVER use `-i` flags (interactive mode not supported)\n- DO NOT push unless explicitly asked\n- DO NOT commit if no changes exist\n\n\n# Task Management\n\nYou have access to the todo_write tool to help you manage and plan tasks. Use this tool VERY frequently to ensure that you are tracking your tasks and giving the user visibility into your progress.\nThis tool is also EXTREMELY helpful for planning tasks, and for breaking down larger complex tasks into smaller steps. If you do not use this tool when planning, you may forget to do important tasks - and that is unacceptable.\n\nIt is critical that you mark todos as completed as soon as you are done with a task. Do not batch up multiple tasks before marking them as completed.\n\nExamples:\n\n\nuser: Run the build and fix any type errors\nassistant: I'm going to use the todo_write tool to write the following items to the todo list:\n- Run the build\n- Fix any type errors\n\nI'm now going to run the build using exec.\n\nLooks like I found 10 type errors. I'm going to use the todo_write tool to write 10 items to the todo list.\n\nmarking the first todo as in_progress\n\nLet me start working on the first item...\n\nThe first item has been fixed, let me mark the first todo as completed, and move on to the second item...\n..\n..\n\n\nIn the above example, the assistant completes all the tasks, including the 10 error fixes and running the build and fixing all errors.\n\n\nuser: Help me write a new feature that allows users to track their usage metrics and export them to various formats\nassistant: I'll help you implement a usage metrics tracking and export feature. Let me first use the todo_write tool to plan this task.\nAdding the following todos to the todo list:\n1. Research existing metrics tracking in the codebase\n2. Design the metrics collection system\n3. Implement core metrics tracking functionality\n4. Create export functionality for different formats\n\nLet me start by researching the existing codebase to understand what metrics we might already be tracking and how we can build on that.\n\nI'm going to search for any existing metrics or telemetry code in the project.\n\nI've found some existing telemetry code. Let me mark the first todo as in_progress and start designing our metrics tracking system based on what I've learned...\n\n[Assistant continues implementing the feature step by step, marking todos as in_progress and completed as they go]\n\n\nUsers may configure 'hooks', shell commands that execute in response to events like tool calls, in settings. Treat feedback from hooks, including , as coming from the user. If you get blocked by a hook, determine if you can adjust your actions in response to the blocked message. If not, ask the user to check their hooks configuration.\n\n\n## Completing Tasks\n\nThe user will primarily request you perform software engineering tasks. This includes solving bugs, adding new functionality, refactoring code, explaining code, and more. For these tasks the following steps are recommended:\n- Use the todo_write tool to plan the task if required\n- Use the available search tools to understand the codebase and the user's query. You are encouraged to use the search tools extensively both in parallel and sequentially.\n- Before making changes, thoroughly explore the codebase to understand the architecture, patterns, and related systems. Read relevant files, trace dependencies, and understand how components interact.\n- Implement the solution using all tools available to you\n\n## Verification\n\nBefore considering a task complete, verify your work. Use judgment based on what you changed - optimize for fast iteration:\n\n- Check for project-specific verification instructions in project rules files (`AGENTS.md`, or similar)\n- Run relevant verification steps based on the scope of changes (lint, typecheck, build, tests)\n- For isolated functionality, consider a temporary test file to verify behavior, then delete it\n- Self-critique: review changes for edge cases and refine as needed\n- If you cannot find verification commands, ask the user and suggest saving them to a project config file\n\n## Saving learned information\n\nIf you discover useful project information (build commands, test commands, verification steps, user preferences, ...) that isn't already documented:\n- If a rules file exists (`AGENTS.md`, etc.), append to it\n- Otherwise, create `AGENTS.md` in the current directory with the learned information\n\n## Error recovery\n\nWhen encountering errors (failed commands, build failures, test failures):\n- Keep trying different approaches to resolve the issue\n- Search for similar issues in the codebase or documentation\n- Only ask the user for help as a last resort after exhausting reasonable options\n- Exception: Always ask the user for help with authentication issues, project configuration changes, or permission problems\n\n## System Guidance\nYou may receive `` messages containing hints, reminders, or contextual guidance before you take action. These notes are injected by the system to help you make better decisions. Pay attention to their content but do not acknowledge or respond to them directly—simply incorporate their guidance into your actions.\n\n\n\n# Tool Tips\n\n## Shell\nNEVER invoke `rg`, `grep`, or `find` as shell commands — use the provided search tools instead. They have been optimized for correct permissions and access.\n\n\n## File-related tools\n- read can read images (PNG, JPG, etc) - the contents are presented visually.\n- For Jupyter notebooks (.ipynb files), use notebook_read instead of read.\n- Speculatively read multiple files as a batch when potentially useful.\n- Do NOT create documentation files to describe your changes or plan. Exception: persistent project info files like `AGENTS.md` are allowed.\n\n\n# Safety\n\nIMPORTANT: Assist with defensive security tasks only. Refuse to create, modify, or improve code that may be used maliciously. Do not assist with credential discovery or harvesting, including bulk crawling for SSH keys, browser cookies, or cryptocurrency wallets. Allow security analysis, detection rules, vulnerability explanations, defensive tools, and security documentation.\n\nIMPORTANT: You must NEVER generate or guess URLs for the user unless you are confident that the URLs are for helping the user with programming. You may use URLs provided by the user in their messages or local files.\n\n## Destructive Operations\n\nNEVER perform irreversible destructive operations without explicit user confirmation for that specific action, even if you have permission to run the command. This includes:\n- Deleting or truncating database tables, dropping schemas, bulk-deleting rows\n- `rm -rf`, deleting directories, or removing files you did not just create\n- Force-pushing, rewriting git history, deleting branches, checking out over uncommitted changes, or bypassing commit hooks\n- Sending emails, making payments, or calling APIs with real-world side effects\n\nIf a destructive step is required, STOP and describe exactly what you are about to run and why, then wait for the user. Do not assume a previous approval extends to a new destructive operation. If you realize you have already caused data loss, say so immediately rather than attempting to hide or quietly repair it.\n\n\n\n## Available MCP Servers (for third-party tools)\n\n{\"servers\":[{\"name\":\"cloudflare-observability\"},{\"name\":\"cloudflare\"},{\"name\":\"cloudflare-docs\"},{\"name\":\"cloudflare-builds\"},{\"name\":\"cloudflare-bindings\"},{\"name\":\"playwright\"},{\"name\":\"fff\",\"description\":\"FFF is a fast file finder with frecency-ranked results (frequent/recent files first, git-dirty files boosted).\\n\\n## Which Tool Should I Use?\\n\\n- **grep**: DEFAULT tool. Searches file CONTENTS -- definitions, usage, patterns. Use when you have a specific name or pattern.\\n- **find_files**: Explores which files/modules exist for a topic. Use when you DON'T have a specific identifier or LOOKING FOR A FILE.\\n- **multi_grep**: OR logic across multiple patterns. Use for case variants (e.g. ['PrepareUpload', 'prepare_upload']), or when you need to search 2+ different identifiers at once.\\n\\n## Core Rules\\n\\n### 1. Search BARE IDENTIFIERS only\\nGrep matches single lines. Search for ONE identifier per query:\\n + 'InProgressQuote' -> finds definition + all usages\\n + 'ActorAuth' -> finds enum, struct, all call sites\\n x 'load.*metadata.*InProgressQuote' -> regex spanning multiple tokens, 0 results\\n x 'ctx.data::' -> code syntax, too specific, 0 results\\n x 'struct ActorAuth' -> adding keywords narrows results, misses enums/traits/type aliases\\n x 'TODO.*#\\\\d+' -> complex regex, use simple 'TODO' then filter visually\\n\\n### 2. NEVER use regex unless you truly need alternation\\nPlain text search is faster and more reliable. Regex patterns like `.*`, `\\\\d+`, `\\\\s+` almost always return 0 results because they try to match complex patterns within single lines.\\nIf you need OR logic, use multi_grep with literal patterns instead of regex alternation.\\n\\n### 3. Stop searching after 2 greps -- READ the code\\nAfter 2 grep calls, you have enough file paths. Read the top result to understand the code.\\nDo NOT keep grepping with variations. More greps != better understanding.\\n\\n### 4. Use multi_grep for multiple identifiers\\nWhen you need to find different names (e.g. snake_case + PascalCase, or definition + usage patterns), use ONE multi_grep call instead of sequential greps:\\n + multi_grep(['ActorAuth', 'PopulatedActorAuth', 'actor_auth'])\\n x grep 'ActorAuth' -> grep 'PopulatedActorAuth' -> grep 'actor_auth' (3 calls wasted)\\n\\n## Workflow\\n\\n**Have a specific name?** -> grep the bare identifier.\\n**Need multiple name variants?** -> multi_grep with all variants in one call.\\n**Exploring a topic / finding files?** -> find_files.\\n**Got results?** -> Read the top file. Don't grep again.\\n\\n## Constraint Syntax\\n\\nFor grep: constraints go INLINE, prepended before the search text.\\nFor multi_grep: constraints go in the separate 'constraints' parameter.\\n\\nConstraints MUST match one of these formats:\\n Extension: '*.rs', '*.{ts,tsx}'\\n Directory: 'src/', 'quotes/'\\n Filename: 'schema.rs', 'src/main.rs'\\n Exclude: '!test/', '!*.spec.ts'\\n\\n! Bare words without extensions are NOT constraints. 'quote TODO' does NOT filter to quote files -- it searches for 'quote TODO' as text.\\n + 'schema.rs TODO' -> searches for 'TODO' in files schema.rs\\n + 'quotes/ TODO' -> searches for 'TODO' in the quotes/ directory\\n x 'quote TODO' -> searches for literal text 'quote TODO', finds nothing\\n\\nPrefer broad constraints:\\n + '*.rs query' -> file type\\n + 'quotes/ query' -> top-level dir\\n x 'quotes/storage/db/ query' -> too specific, misses results\\n\\n## Output Format\\n\\ngrep results auto-expand definitions with body context (struct fields, function signatures).\\nThis often provides enough information WITHOUT a follow-up Read call.\\nLines marked with | are definition body context. [def] marks definition files.\\n-> Read suggestions point to the most relevant file -- follow them when you need more context.\\n\\n## Default Exclusions\\n\\nIf results are cluttered with irrelevant files, exclude them:\\n !tests/ - exclude tests directory\\n !*.spec.ts - exclude test files\\n !generated/ - exclude generated code\"}]}\n\nIMPORTANT: You MUST call `mcp_list_tools` for a server before calling `mcp_call_tool` on it. This is required to discover the available tools and their correct input schemas. Never guess tool names or arguments — always list tools first.\n","metadata":{"metrics":null,"telemetry":{"source":"sysprompt","operation":"normal"},"created_at":"2026-07-14T23:36:58.430959Z","num_tokens":null,"request_id":null,"finish_reason":null,"is_user_input":null},"message_id":"8cad11a1-cb52-4e83-baec-35dfdddd1590"}],"tool_availability":{"BlockList":[{"Name":{"exact":"exit_plan_mode"}}]},"append_system_messages":[]},{"model":"swe-1-7-lightning","source":{"Session":"System"},"context":[],"lifetime":{"Unique":"core/model"},"permissions":[],"user_display":[],"footer_messages":[],"set_system_prefix":null,"tool_availability":{"AllowList":[{"Name":{"exact":"exec"}},{"Name":{"exact":"read"}},{"Name":{"exact":"edit"}},{"Name":{"exact":"grep"}},{"Name":{"exact":"glob"}},{"Name":{"exact":"exit_plan_mode"}},{"Name":{"literal":"get_output"}},{"Name":{"literal":"kill_shell"}},{"Name":{"literal":"write_to_process"}},{"Name":{"literal":"write"}},{"Name":{"literal":"notebook_read"}},{"Name":{"literal":"notebook_edit"}},{"Name":{"literal":"todo_write"}},{"Name":{"literal":"webfetch"}},{"Name":{"literal":"web_search"}},{"Name":{"literal":"ask_user_question"}},{"Name":{"literal":"run_subagent"}},{"Name":{"literal":"read_subagent"}},{"Name":{"literal":"request_scope"}},{"Name":{"literal":"mcp_call_tool"}},{"Name":{"literal":"mcp_list_servers"}},{"Name":{"literal":"mcp_list_tools"}},{"Name":{"literal":"mcp_read_resource"}},{"Name":{"literal":"skill"}}]},"append_system_messages":[{"role":"system","content":"You are powered by SWE-1.7 Lightning.","metadata":{"metrics":null,"telemetry":{"source":"system","operation":"unknown"},"created_at":"2026-07-14T23:36:58.431225Z","num_tokens":null,"request_id":null,"finish_reason":null,"is_user_input":null},"message_id":"24eab259-b7f8-4a52-b065-c2dbc6c5f083"}]},{"model":null,"source":{"Session":"System"},"context":[],"lifetime":{"Unique":"core/parallel-tool-calls"},"permissions":[],"user_display":[],"footer_messages":[],"set_system_prefix":null,"tool_availability":null,"append_system_messages":[{"role":"system","content":"## Parallel tool calls\n\n- You have the capability to call multiple tools in a single response--when multiple independent pieces of information are requested, batch your tool calls together for optimal performance.\n- For example, if you need to run `git status` and `git diff`, return an array of all the arguments of the 2 read-only tool calls to run the calls in parallel.\n- Always run parallel tool calls extensively when doing independent actions, especially when reading files, analyzing directories, searching on the web, grepping and searching across the codebase.\n- Never perform dependent terminal commands or writes in parallel.","metadata":{"metrics":null,"telemetry":{"source":"system","operation":"unknown"},"created_at":"2026-07-14T23:36:58.431240Z","num_tokens":null,"request_id":null,"finish_reason":null,"is_user_input":null},"message_id":"38055991-b8bc-4f2f-acd3-771314303f07"}]},{"model":null,"source":"Subagent","context":[],"lifetime":{"Unique":"core/read_only_kinds"},"permissions":[[{"Tool":{"Kind":"read"}},"Allow"],[{"Tool":{"Kind":"search"}},"Allow"],[{"Tool":{"Kind":"think"}},"Allow"]],"user_display":[],"footer_messages":[],"set_system_prefix":null,"tool_availability":null,"append_system_messages":[]},{"model":null,"source":{"Session":"System"},"context":[],"lifetime":{"Unique":"core/subagent_profiles"},"permissions":[],"user_display":[],"footer_messages":[],"set_system_prefix":null,"tool_availability":null,"append_system_messages":[{"role":"system","content":"Available subagent profiles for the `run_subagent` tool.

These are only read for compatibility, not written to.\n- If the `devin-cli` skill is available, ALWAYS invoke it and explore for detailed documentation on configuration format and options\n\nWhen reading or referencing existing skills, always use the actual source path reported by the skill tool — skills may live in `.devin/`, `.agents/`, or other directories.\n\n\n# Modes\n\nThe active mode is how the user would like you to act.\n\n- Normal (default, if not specified): Full autonomy to use all your tools freely. For example: exploring a codebase, writing or editing code, etc.\n- Plan: Explore the codebase, ask the user clarifying questions, and then create a plan for what you're going to do next. Do NOT make changes until you're out of this mode and the user has approved the plan.\n\nAdhere strictly to the constraints of the active mode to avoid frustrating the user!\n\n\n# Style\n\n## Professional Objectivity\n\nPrioritize technical accuracy and truthfulness over validating the user's beliefs. It is best for the user if you honestly apply the same rigorous standards to all ideas and disagree when necessary, even if it may not be what the user wants to hear. Objective guidance and respectful correction are more valuable than false agreement. Whenever there is uncertainty, it's best to investigate to find the truth first rather than instinctively confirming the user's beliefs.\n\n## Tone\n\n- Be concise, direct, and to the point. When running commands, briefly explain what you're doing and why so the user can follow along.\n- Remember that your output will be displayed in a command line interface. Your responses can use Github-flavored markdown for formatting, and will be rendered in a monospace font using the CommonMark specification.\n- Output text to communicate with the user; all text you output outside of tool use is displayed to the user. Only use tools to complete tasks. Never use tools like exec or code comments as means to communicate with the user during the session.\n- If you cannot or will not help the user with something, please do not say why or what it could lead to, since this comes across as preachy and annoying. Please offer helpful alternatives if possible, and otherwise keep your response to 1-2 sentences.\n- Only use emojis if the user explicitly requests it. Avoid using emojis in all communication unless asked.\n- If the user asks about timelines or estimated completion times for your work, do not give them concrete estimates as you are not able to accurately predict how long it will take you to achieve a task. Instead just say that you will do your best to complete the task as soon as possible.\n- Avoid guessing. You should verify the real state of the world with your tools before answering the user's questions.\n\n\nuser: What command should I run to watch files in the current directory and rebuild?\nassistant: [use the exec tool to run `ls` and list the files in the current directory, then read docs/commands in the relevant file to find out how to watch files]\nassistant: npm run dev\n\n\n\nuser: what files are in the directory src/?\nassistant: [runs ls and sees foo.c, bar.c, baz.c]\nassistant: foo.c, bar.c, baz.c\nuser: which file contains the implementation of Foo?\nassistant: [reads foo.c]\nassistant: src/foo.c contains `struct Foo`, which implements [...]\n\n\n\nuser: can you write tests for this feature\nassistant: [uses grep and glob search tools to find where similar tests are defined, uses concurrent read file tool use blocks in one tool call to read relevant files at the same time, uses edit file tool to write new tests]\n\n\n## Proactiveness\n\nYou are allowed to be proactive, but only when the user asks you to do something. You should strive to strike a balance between:\n\n1. Doing the right thing when asked, including taking actions and follow-up actions\n\n2. Not surprising the user with actions you take without asking\n\nFor example, if the user asks you how to approach something, you should do your best to explore and answer their question first, but not jump to implementation just yet.\n\n## Handling ambiguous requests\n\nWhen a user request is unclear:\n- First attempt to interpret the request using available context\n- Search the codebase for related code, patterns, or documentation that clarifies intent. Also consider searching the web.\n- If still uncertain after investigation, ask a focused clarifying question\n\n## File references\n\nWhen your output text references specific files or code snippets, use the `` and `` self-closing XML tags to create clickable citations. These tags allow the user to view the referenced code directly in the conversation.\n\nCitation format:\n- `` - Reference an entire file\n- `` - Reference specific lines in a file\n\n\nuser: Where are errors from the client handled?\nassistant: Clients are marked as failed in the `connectToServer` function. \n\n\n\nuser: Can you show me the config file?\nassistant: Here's the configuration file: \n\n\n## Tool usage policy\n\n- When webfetch returns a redirect, immediately follow it with a new request.\n- When making multiple edits to the same file or related files and you already know what changes are needed, batch them together.\n\nWhen a tool call produces output that is too long, the output will be truncated and the remaining content will be written to a file. You will see a `` tag containing the path to the overflow file. You are responsible for reading this file if you need the full output.\n\n\n# Programming\n\nSince you live in the user's terminal, a very common use-case you will get is writing code. Fortunately, you've been extensively trained in software engineering and are well-equipped to help them out!\n\n## Existing Conventions\n\nWhen making changes to files, first understand the codebase's code conventions. Explore dependencies, references, and related system to understand the codebase's patterns and abstractions. Mimic code style, use existing libraries and utilities, and follow existing patterns.\n- NEVER assume that a given library is available, even if it is well known. Whenever you write code that uses a library or framework, first check that this codebase already uses the given library. For example, you might look at neighboring files, or check the package.json (or cargo.toml, and so on depending on the language). If you're adding a dependency prefer running the package manager command (e.g. npm add or cargo add) instead of editing the file.\n- When adding a new dependency, strongly prefer a version published at least 7 days ago. Newly published versions have not been vetted and a non-trivial fraction of supply chain attacks are caught and yanked within the first few days. Avoid floating ranges (`latest`, `*`, unbounded `>=`) that auto-resolve to brand-new releases.\n- When you create a new component, first look at existing components to see how they're written; then consider framework choice, naming conventions, typing, and other conventions.\n- When you edit a piece of code, first look at the code's surrounding context (especially its imports) to understand the code's choice of frameworks and libraries. Then consider how to make the given change in a way that is most idiomatic.\n- Always follow security best practices. Never introduce code that exposes or logs secrets and keys. Never commit secrets or keys to the repository. Never modify repository security policies or compliance controls (e.g. `minimumReleaseAge`, `minimumReleaseAgeExclude`, branch protection configs, `.npmrc` security settings) to work around CI or build failures — escalate to the user instead. Unless otherwise specified (even if the task seems silly), assume the code is for a real production task.\n\n## Code style\n\n- IMPORTANT: Do NOT add or remove comments unless asked! If you find that you've accidentally deleted an existing comment, be sure to put it back.\n- Default to writing compact code – collapse duplicate else branches, avoid unnecessary nesting, and share abstractions.\n- Follow idiomatic conventions for the language you're writing.\n- Avoid excessive & verbose error handling in your code. Errors should be handled, but not every line needs to be try/catched. Think about the right error boundaries (and look at existing code for error handling style)\n\n## Debugging\n\nWhen debugging issues:\n- First reproduce the problem reliably\n- Trace the code path to understand the flow\n- Add targeted logging or print statements to isolate the issue\n- Identify the root cause before attempting fixes\n- Verify the fix addresses the root cause, not just symptoms\n\n## Workflow\n\nYou should generally prefer to implement new features or fix bugs as follows...\n\n1. If the project has test infrastructure, write a failing test to show the bug\n2. Fix the bug\n3. Ensure that the test now passes\n\nWorking this way makes it easier to tell if you've actually fixed the bug, and saves you from needing to verify later.\n\n## Git\n\n### Creating commits\n1. Run in parallel: `git status`, `git diff`, `git log` (to match commit style)\n2. Draft a concise commit message focusing on \"why\" not \"what\". Check for sensitive info.\n3. Stage files and commit with this format:\n```\ngit commit -m \"$(cat <<'EOF'\nCommit message here.\n\nGenerated with [Devin](https://devin.ai)\n\nCo-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>\nEOF\n)\"\n```\n4. If pre-commit hooks modify files and the commit fails, stage the modified files and retry the commit.\n\n### Creating pull requests\nUse `gh` for all GitHub operations. Run in parallel: `git status`, `git diff`, `git log`, `git diff main...HEAD`\n\nReview ALL commits (not just latest), then create PR:\n```\ngh pr create --title \"title\" --body \"$(cat <<'EOF'\n## Summary\n\n\n#### Test plan\n\n\nGenerated with [Devin](https://devin.ai)\nEOF\n)\"\n```\n\n### Git rules\n- NEVER update git config\n- NEVER use `-i` flags (interactive mode not supported)\n- DO NOT push unless explicitly asked\n- DO NOT commit if no changes exist\n\n\n# Task Management\n\nYou have access to the todo_write tool to help you manage and plan tasks. Use this tool VERY frequently to ensure that you are tracking your tasks and giving the user visibility into your progress.\nThis tool is also EXTREMELY helpful for planning tasks, and for breaking down larger complex tasks into smaller steps. If you do not use this tool when planning, you may forget to do important tasks - and that is unacceptable.\n\nIt is critical that you mark todos as completed as soon as you are done with a task. Do not batch up multiple tasks before marking them as completed.\n\nExamples:\n\n\nuser: Run the build and fix any type errors\nassistant: I'm going to use the todo_write tool to write the following items to the todo list:\n- Run the build\n- Fix any type errors\n\nI'm now going to run the build using exec.\n\nLooks like I found 10 type errors. I'm going to use the todo_write tool to write 10 items to the todo list.\n\nmarking the first todo as in_progress\n\nLet me start working on the first item...\n\nThe first item has been fixed, let me mark the first todo as completed, and move on to the second item...\n..\n..\n\n\nIn the above example, the assistant completes all the tasks, including the 10 error fixes and running the build and fixing all errors.\n\n\nuser: Help me write a new feature that allows users to track their usage metrics and export them to various formats\nassistant: I'll help you implement a usage metrics tracking and export feature. Let me first use the todo_write tool to plan this task.\nAdding the following todos to the todo list:\n1. Research existing metrics tracking in the codebase\n2. Design the metrics collection system\n3. Implement core metrics tracking functionality\n4. Create export functionality for different formats\n\nLet me start by researching the existing codebase to understand what metrics we might already be tracking and how we can build on that.\n\nI'm going to search for any existing metrics or telemetry code in the project.\n\nI've found some existing telemetry code. Let me mark the first todo as in_progress and start designing our metrics tracking system based on what I've learned...\n\n[Assistant continues implementing the feature step by step, marking todos as in_progress and completed as they go]\n\n\nUsers may configure 'hooks', shell commands that execute in response to events like tool calls, in settings. Treat feedback from hooks, including , as coming from the user. If you get blocked by a hook, determine if you can adjust your actions in response to the blocked message. If not, ask the user to check their hooks configuration.\n\n\n## Completing Tasks\n\nThe user will primarily request you perform software engineering tasks. This includes solving bugs, adding new functionality, refactoring code, explaining code, and more. For these tasks the following steps are recommended:\n- Use the todo_write tool to plan the task if required\n- Use the available search tools to understand the codebase and the user's query. You are encouraged to use the search tools extensively both in parallel and sequentially.\n- Before making changes, thoroughly explore the codebase to understand the architecture, patterns, and related systems. Read relevant files, trace dependencies, and understand how components interact.\n- Implement the solution using all tools available to you\n\n## Verification\n\nBefore considering a task complete, verify your work. Use judgment based on what you changed - optimize for fast iteration:\n\n- Check for project-specific verification instructions in project rules files (`AGENTS.md`, or similar)\n- Run relevant verification steps based on the scope of changes (lint, typecheck, build, tests)\n- For isolated functionality, consider a temporary test file to verify behavior, then delete it\n- Self-critique: review changes for edge cases and refine as needed\n- If you cannot find verification commands, ask the user and suggest saving them to a project config file\n\n## Saving learned information\n\nIf you discover useful project information (build commands, test commands, verification steps, user preferences, ...) that isn't already documented:\n- If a rules file exists (`AGENTS.md`, etc.), append to it\n- Otherwise, create `AGENTS.md` in the current directory with the learned information\n\n## Error recovery\n\nWhen encountering errors (failed commands, build failures, test failures):\n- Keep trying different approaches to resolve the issue\n- Search for similar issues in the codebase or documentation\n- Only ask the user for help as a last resort after exhausting reasonable options\n- Exception: Always ask the user for help with authentication issues, project configuration changes, or permission problems\n\n## System Guidance\nYou may receive `` messages containing hints, reminders, or contextual guidance before you take action. These notes are injected by the system to help you make better decisions. Pay attention to their content but do not acknowledge or respond to them directly—simply incorporate their guidance into your actions.\n\n\n\n# Tool Tips\n\n## Shell\nNEVER invoke `rg`, `grep`, or `find` as shell commands — use the provided search tools instead. They have been optimized for correct permissions and access.\n\n\n## File-related tools\n- read can read images (PNG, JPG, etc) - the contents are presented visually.\n- For Jupyter notebooks (.ipynb files), use notebook_read instead of read.\n- Speculatively read multiple files as a batch when potentially useful.\n- Do NOT create documentation files to describe your changes or plan. Exception: persistent project info files like `AGENTS.md` are allowed.\n\n\n# Safety\n\nIMPORTANT: Assist with defensive security tasks only. Refuse to create, modify, or improve code that may be used maliciously. Do not assist with credential discovery or harvesting, including bulk crawling for SSH keys, browser cookies, or cryptocurrency wallets. Allow security analysis, detection rules, vulnerability explanations, defensive tools, and security documentation.\n\nIMPORTANT: You must NEVER generate or guess URLs for the user unless you are confident that the URLs are for helping the user with programming. You may use URLs provided by the user in their messages or local files.\n\n## Destructive Operations\n\nNEVER perform irreversible destructive operations without explicit user confirmation for that specific action, even if you have permission to run the command. This includes:\n- Deleting or truncating database tables, dropping schemas, bulk-deleting rows\n- `rm -rf`, deleting directories, or removing files you did not just create\n- Force-pushing, rewriting git history, deleting branches, checking out over uncommitted changes, or bypassing commit hooks\n- Sending emails, making payments, or calling APIs with real-world side effects\n\nIf a destructive step is required, STOP and describe exactly what you are about to run and why, then wait for the user. Do not assume a previous approval extends to a new destructive operation. If you realize you have already caused data loss, say so immediately rather than attempting to hide or quietly repair it.\n\n\n\n## Available MCP Servers (for third-party tools)\n\n{\"servers\":[{\"name\":\"cloudflare-observability\"},{\"name\":\"cloudflare\"},{\"name\":\"cloudflare-docs\"},{\"name\":\"cloudflare-builds\"},{\"name\":\"cloudflare-bindings\"},{\"name\":\"playwright\"},{\"name\":\"fff\",\"description\":\"FFF is a fast file finder with frecency-ranked results (frequent/recent files first, git-dirty files boosted).\\n\\n## Which Tool Should I Use?\\n\\n- **grep**: DEFAULT tool. Searches file CONTENTS -- definitions, usage, patterns. Use when you have a specific name or pattern.\\n- **find_files**: Explores which files/modules exist for a topic. Use when you DON'T have a specific identifier or LOOKING FOR A FILE.\\n- **multi_grep**: OR logic across multiple patterns. Use for case variants (e.g. ['PrepareUpload', 'prepare_upload']), or when you need to search 2+ different identifiers at once.\\n\\n## Core Rules\\n\\n### 1. Search BARE IDENTIFIERS only\\nGrep matches single lines. Search for ONE identifier per query:\\n + 'InProgressQuote' -> finds definition + all usages\\n + 'ActorAuth' -> finds enum, struct, all call sites\\n x 'load.*metadata.*InProgressQuote' -> regex spanning multiple tokens, 0 results\\n x 'ctx.data::' -> code syntax, too specific, 0 results\\n x 'struct ActorAuth' -> adding keywords narrows results, misses enums/traits/type aliases\\n x 'TODO.*#\\\\d+' -> complex regex, use simple 'TODO' then filter visually\\n\\n### 2. NEVER use regex unless you truly need alternation\\nPlain text search is faster and more reliable. Regex patterns like `.*`, `\\\\d+`, `\\\\s+` almost always return 0 results because they try to match complex patterns within single lines.\\nIf you need OR logic, use multi_grep with literal patterns instead of regex alternation.\\n\\n### 3. Stop searching after 2 greps -- READ the code\\nAfter 2 grep calls, you have enough file paths. Read the top result to understand the code.\\nDo NOT keep grepping with variations. More greps != better understanding.\\n\\n### 4. Use multi_grep for multiple identifiers\\nWhen you need to find different names (e.g. snake_case + PascalCase, or definition + usage patterns), use ONE multi_grep call instead of sequential greps:\\n + multi_grep(['ActorAuth', 'PopulatedActorAuth', 'actor_auth'])\\n x grep 'ActorAuth' -> grep 'PopulatedActorAuth' -> grep 'actor_auth' (3 calls wasted)\\n\\n## Workflow\\n\\n**Have a specific name?** -> grep the bare identifier.\\n**Need multiple name variants?** -> multi_grep with all variants in one call.\\n**Exploring a topic / finding files?** -> find_files.\\n**Got results?** -> Read the top file. Don't grep again.\\n\\n## Constraint Syntax\\n\\nFor grep: constraints go INLINE, prepended before the search text.\\nFor multi_grep: constraints go in the separate 'constraints' parameter.\\n\\nConstraints MUST match one of these formats:\\n Extension: '*.rs', '*.{ts,tsx}'\\n Directory: 'src/', 'quotes/'\\n Filename: 'schema.rs', 'src/main.rs'\\n Exclude: '!test/', '!*.spec.ts'\\n\\n! Bare words without extensions are NOT constraints. 'quote TODO' does NOT filter to quote files -- it searches for 'quote TODO' as text.\\n + 'schema.rs TODO' -> searches for 'TODO' in files schema.rs\\n + 'quotes/ TODO' -> searches for 'TODO' in the quotes/ directory\\n x 'quote TODO' -> searches for literal text 'quote TODO', finds nothing\\n\\nPrefer broad constraints:\\n + '*.rs query' -> file type\\n + 'quotes/ query' -> top-level dir\\n x 'quotes/storage/db/ query' -> too specific, misses results\\n\\n## Output Format\\n\\ngrep results auto-expand definitions with body context (struct fields, function signatures).\\nThis often provides enough information WITHOUT a follow-up Read call.\\nLines marked with | are definition body context. [def] marks definition files.\\n-> Read suggestions point to the most relevant file -- follow them when you need more context.\\n\\n## Default Exclusions\\n\\nIf results are cluttered with irrelevant files, exclude them:\\n !tests/ - exclude tests directory\\n !*.spec.ts - exclude test files\\n !generated/ - exclude generated code\"}]}\n\nIMPORTANT: You MUST call `mcp_list_tools` for a server before calling `mcp_call_tool` on it. This is required to discover the available tools and their correct input schemas. Never guess tool names or arguments — always list tools first.\n","created_at":"2026-07-14T23:36:58.430959Z","finish_reason":null,"metrics":null},{"message_id":"337e4819-eed9-447e-a232-be0548b5b5e5","node_id":19,"role":"system","content":"Available subagent profiles for the `run_subagent` tool.

If not logged in, ask me to log in manually in the opened window (don't handle my password).\n3. Once on `https://x.com/home`, read `ct0` from `document.cookie`:\n `document.cookie.match(/ct0=([^;]+)/)[1]`\n4. Call X's GraphQL endpoints directly via `fetch()` inside `browser_evaluate`. Required headers:\n - `authorization: Bearer AAAAAAAAAAAAAAAAAAAAANRILgAAAAAAnNwIzUejRCOuH5E6I8xnZz4puTs%3D1Zv7ttfk8LF81IUq16cHjhLTvJu4FA33AGWWjCpTnA` (the public web-app bearer token)\n - `x-csrf-token: `\n - `x-twitter-auth-type: OAuth2Session`\n - `x-twitter-active-user: yes`\n - `content-type: application/json`\n5. Paginate timelines by reading `content.cursorType === \"Bottom\"` entries and passing\n the value back as `variables.cursor` until it stops changing.\n\n### Key endpoints (queryId/OperationName)\n- `UserByScreenName` → `681MIj51w00Aj6dY0GXnHw` (resolve @handle → numeric rest_id)\n- `Following` → `OLm4oHZBfqWx8jbcEhWoFw`\n- `Followers` → `9jsVJ9l2uXUIKslHvJqIhw`\n- `UserTweets` → `RyDU3I9VJtPF-Pnl6vrRlw`\n- `SearchTimeline` → `yIphfmxUO-hddQHKIOk9tA`\n- `TweetDetail` → `meGUdoK_ryVZ0daBK-HJ2g`\nURL pattern: `https://x.com/i/api/graphql//?variables=&features=`\n\n### Response schema notes (current X web build)\n- User objects now put `screen_name` / `name` under `core`, NOT `legacy.screen_name`.\n twscrape's parser still reads `legacy.screen_name` and returns empty — needs updating.\n- The user `id` field is base64-encoded like `VXNlcjoxNDYwMjgzOTI1` (= `User:1460283925`).\n Decode with `atob(u.id).split(':')[1]` to get the numeric rest_id. `u.rest_id` may also\n be present directly.\n- `is_blue_verified` is the verified flag. `legacy.followers_count`, `legacy.description`\n still exist under `legacy`.\n- Filter timeline entries by `content.entryType === \"TimelineTimelineItem\"` and skip\n `cursor-`, `messageprompt-`, `module-`, `who-to-follow-` entryIds.\n\n### Features dict\nUse the full `GQL_FEATURES` block from twscrape's `api.py` — without it X returns\n`(336) The following features cannot be null`. Pass it URL-encoded as the `features` param.\n\n### Where things live\n- Output CSV: `~/Downloads/utilities/sdand_following.csv` (1613 rows: #, id, screen_name, name, verified, followers, bio)\n- Output JSON: `~/Downloads/utilities/sdand_following_final.json` (double-encoded JSON string; parse with `json.loads(json.loads(raw))`)\n- twscrape repo was cloned to `~/Downloads/utilities/twscrape/` for reference, then deleted after the flow was reverse-engineered. Re-clone from https://github.com/vladkens/twscrape.git if needed.\n\n## Fast Whisper transcription on Modal (A10G)\n\nFor transcribing long-form audio/video (interviews, podcasts, X/Twitter videos), use the\nutility at `~/Downloads/utilities/whisper_x/whisper_transcribe.py`. It does the full\npipeline: URL → yt-dlp download → ffmpeg audio extract → Modal volume upload →\nfaster-whisper on A10G → JSON + TXT output. Validated at **2.3 min wall clock for 65 min\nof audio** (no caching at any layer).\n\n### Usage\nShell alias (defined in `~/.zshrc`): `whisper`\n```bash\n# Transcribe an X/Twitter video (picks first playlist item)\nwhisper \"https://x.com/.../status/123\"\n\n# Pick a specific playlist item, use a smaller model\nwhisper \"https://x.com/...\" --playlist-item 2 --model-size medium\n\n# Transcribe a local audio file\nwhisper /path/to/audio.mp3 --name my-podcast\n\n# Custom output dir + keep downloaded source\nwhisper \"https://...\" --outdir ./transcripts --keep-source\n```\nTranscript text goes to stdout (pipe with `| pbcopy`); structured JSON + readable TXT\nsaved to `/.json` and `/.txt`.\n\n### Key optimizations (vs naive T4 run that took 11.7 min)\n- **A10G GPU** (~8x fp16 throughput vs T4; Modal ~$0.60/hr vs ~$0.16/hr — pennies for short jobs)\n- **`BatchedInferencePipeline`** with `batch_size=16` — batches encoder/decoder across chunks (2-4x)\n- **`beam_size=1`** (greedy) — ~2x faster, negligible WER increase for conversational speech\n- **`vad_filter=True`** — skips silence segments\n- **`compute_type=\"float16\"`** — halves memory bandwidth\n- **No caching**: `force_build=True` on apt/pip steps + unique `download_root` per run forces\n fresh image rebuild + fresh HF model download every time\n\n### Pinned versions (must match)\n- `faster-whisper==1.1.1` (provides `BatchedInferencePipeline`)\n- `ctranslate2==4.8.0`\n- Base image: `nvidia/cuda:12.6.3-cudnn-runtime-ubuntu22.04` (provides `libcublas.so.12`;\n `debian_slim` fails with `RuntimeError: Library libcublas.so.12 is not found`)\n\n### Audio prep (done automatically by the utility)\n```bash\nffmpeg -y -i input.mp4 -vn -ac 1 -ar 16000 -c:a aac -b:a 64k audio.m4a\n```\nMono 16kHz 64kbps AAC — a 65-min video (151 MB stream) becomes ~35 MB audio.\n\n### X/Twitter download notes\n- Tweet URLs can contain **playlists** (multiple videos). Use `--playlist-item N` to pick one.\n- Always use `-f bestaudio/best` to avoid downloading multi-GB high-bitrate video streams.\n- A 65-min interview's video variant can be 2.8+ GB; audio-only is ~63 MB (128 kbps).\n\n### Where things live\n- Utility: `~/Downloads/utilities/whisper_x/whisper_transcribe.py`\n- Strategy doc: `~/Downloads/utilities/whisper_x/STRATEGY.md` (full optimization breakdown)\n- Modal app (standalone): `~/Downloads/utilities/whisper_x/transcribe_fast.py`\n- Modal volume: `whisper-audio` (created automatically; holds uploaded audio files)\n- Modal profile: `aidenhuang-personal` (workspace with GPU access)\n\n\n\n\n\n\n","created_at":"2026-07-14T23:36:58.431601Z","finish_reason":null,"metrics":null},{"message_id":"2aff2862-c128-48ee-b99a-051f27a5f2fa","node_id":24,"role":"user","content":"find all subdomains of concept.dev via crt.sh","created_at":"2026-07-14T23:37:07.008070Z","finish_reason":null,"metrics":null},{"message_id":"9824ebf8-363f-4563-8ddd-04d09bb0629b","node_id":27,"role":"assistant","content":"","tool_calls":[{"id":"functions.exec:0","name":"exec","arguments":{"command":"curl -s \"https://crt.sh/?q=%.concept.dev&output=json\" | jq -r '.[].name_value' | sort -u","timeout":30000}}],"thinking":"The user wants to find all subdomains of concept.dev via crt.sh.

Need to define \"live\" perhaps DNS resolves and maybe HTTP responds. Likely DNS resolution at least. I can script a check for all listed subdomains. We have list of 30 actual hostnames. I can run a loop with dig +short and report those resolving. Also maybe check HTTP 200? But \"live\" can mean resolves. Could do both DNS and HTTP HEAD quickly. Need to be careful not to make too many network requests? It's fine. Use bash loop with dig +short and curl -I. Could output list. Since low-effort, one script. Need to construct list. Could fetch crt.sh again and test, but to save time use already known list. Maybe use a script that fetches crt.sh, dedupes, strips wildcards, then checks DNS and HTTP. But that repeats. Better to write a one-liner that checks all. Need to be efficient. We can generate list inline or fetch. It went background before. Could set a longer timeout. Use a shell script with functions.\n\nWe need to determine live subdomains. I can use `host` or `dig` and `curl -s -o /dev/null -w '%{http_code} %{redirect_url}\\n' --max-time 5`. Some may redirect. Also need to handle wildcard certs? The list. Let's fetch JSON and process with jq. Since curl to crt.sh takes a few seconds, maybe combine. To avoid background, set timeout > expected. Use `curl -m 20` and pipe. Then loop. The total could take 30+ seconds due to 30 HTTP checks. The default idle timeout is 5s, which may background if no output for 5s. Use `timeout` parameter in exec to avoid? The idle_timeout default 5s means if no output for 5s it returns. Setting `timeout` won't override idle? Actually exec has `timeout` and `idle_timeout`. Need to set idle_timeout longer. Use e.g. idle_timeout: 60000, timeout: 120000. Also output lines as they occur by printing progress to avoid idle. Good.\n\nScript plan:\n\n1. Fetch crt.sh JSON.\n2. Extract name_value, strip leading \"*.\", dedupe, filter out apex.\n3. For each host, check DNS: `dig +short A $h | head -1`. If empty, maybe AAAA. Also check if it CNAMEs. Could do `getent hosts` or `dig +short`.\n4. For those resolving, do `curl -sI --max-time 5 -L`? `-I` HEAD might not be supported by all; maybe `-s -o /dev/null -w '%{http_code}' --max-time 5 -L` GET? HEAD is less intrusive. Use `curl -I -L --max-time 5 -s -w '%{http_code} %{url_effective}'`. But with -I and -L, curl may send HEAD to each redirect and final. Some servers reject HEAD, so GET with range? Better use `curl -s -o /dev/null -w '%{http_code}' --max-time 5 -L \"$url\"`, which downloads body (small). For 30 hosts might be okay. But could be slower. Use `curl -I` for speed and note status. If HEAD fails, maybe mark as no response.\n\nAlternatively use `httpx` if installed. But may not. Use curl.\n\nCould also check HTTPS only since HTTP might not serve. Use `https://$h`. Some may not have HTTPS. Use both? For live, start with https. Cloudflare may respond 403/200.\n\nNeed to decide output format. Maybe a markdown table: Host | DNS (A/AAAA/CNAME) | HTTP status | Notes. But building a table in shell is okay.\n\nLet's write script:\n\n```bash\ncurl -s \"https://crt.sh/?q=%.concept.dev&output=json\" | \\\njq -r '[.[] | .name_value] | .[]' | \\\nsed 's/^*\\.//' | sort -u | \\\ngrep -v '^concept\\.dev$' | \\\nwhile read h; do\n # DNS\n ips=$(dig +short A \"$h\" | head -5 | tr '\\n' ' ')\n cname=$(dig +short CNAME \"$h\" | head -1)\n if [ -z \"$ips\" ] && [ -z \"$cname\" ]; then\n # maybe wildcard DNS? dig can return NXDOMAIN. Try one more with AAAA\n ips=$(dig +short AAAA \"$h\" | head -3 | tr '\\n' ' ')\n fi\n if [ -n \"$ips\" ] || [ -n \"$cname\" ]; then\n status=$(curl -sI -L --max-time 5 -o /dev/null -w '%{http_code}' \"https://$h\" 2>/dev/null)\n echo \"$h | DNS: ${cname}${ips} | HTTPS: $status\"\n else\n echo \"$h | NXDOMAIN\"\n fi\ndone\n```\n\nBut printing each line as processed avoids idle timeout. However, dig/curl per host may be slow. Use parallel? We could use `xargs -P` or `parallel`. Simpler: sequential. Total maybe ~30*2s=60s. Set idle_timeout 30s and timeout 120s. Ensure output.\n\nBut `dig +short A` returns CNAME if CNAME record? dig +short A for a CNAME will follow and return CNAME chain and A? Let's recall `dig +short A name` returns CNAME target and A records if exists? Actually `dig +short` with type A returns only A records? It may also print CNAME then A. For pure CNAME with no A, it returns empty. We'll separately query CNAME.\n\nSimplify: use `getent hosts $h` or `host $h` which returns easy. `host` on macOS available. `host -t A $h` returns A, `host -t CNAME $h`. But `host` output needs parsing. `getent hosts` returns both A and AAAA? On macOS `getent` not available. Use `dig`.\n\nMaybe use `drill`? Not needed.\n\nCould use `curl --resolve`? No.\n\nNeed to produce result. Since this might be long, we should use a shell script and maybe capture to file. Could output. Let's implement in one exec. Use `set -o pipefail`? Not needed. Use `printf` for progress.\n\nConcern: `curl -sI -L` with HEAD may fail for some hosts (405) even if site live. But it will show status code 405 which means server responds. That's fine. Some Cloudflare pages may 526/403. We'll report HTTP status. A live subdomain might have a valid cert but 403/401. We'll list any with DNS + HTTP response (including non-2xx). Could also include DNS-only live.\n\nNeed to handle timeouts: if curl times out, status empty. Use a timeout shorter. For 30 hosts, maybe use `xargs -P 8` to parallelize DNS and curl. Could be faster. But complex. Let's use `while` sequential but set max-time 4s. 30*4=120. Fine.\n\nBetter: Use a temporary script to test DNS and HTTP in parallel with `xargs -P 5`. Use `printf`? But output from parallel may interleave. Use `flock`? Too complex. Sequential acceptable.\n\nNeed to ensure we don't accidentally hammer. 30 requests okay.\n\nMaybe a simpler approach: use `httprobe`? Not installed. Use `curl`.\n\nLet's run the script. Also maybe check HTTP first then DNS? No, DNS needed.\n\nLet's prepare command.","created_at":"2026-07-14T23:39:56.670953Z","finish_reason":"tool_calls","metrics":{"ttft_ms":542,"total_time_ms":5539,"input_tokens":240,"output_tokens":1950,"cache_read_tokens":20352,"cache_creation_tokens":null,"tpot_ms":2.5625641025641026,"tokens_per_sec":390.23414048429055}},{"message_id":"0a8bb9b1-4a38-4095-8522-74a2973cf75c","node_id":61,"role":"tool","content":"Output from command in shell 4ed1cd:\n\n\nExit code: 0","created_at":"2026-07-14T23:40:16.713328Z","finish_reason":null,"metrics":null},{"message_id":"f5b04f51-4cf8-42db-9747-91bd9b5890f1","node_id":63,"role":"assistant","content":"","tool_calls":[{"id":"functions.exec:10","name":"exec","arguments":{"command":"curl -s --max-time 20 \"https://crt.sh/?q=%.concept.dev&output=json\" | jq -r '[.[] | .name_value] | .[]' | sed 's/^\\*\\.//' | sort -u | grep -v '^concept\\.dev$' | head -5","idle_timeout":60000,"timeout":30000}}],"thinking":"No output?

Need interpret and present. \"Live\" could mean DNS resolves and HTTPS responds (status not ERR/NXDOMAIN). We should compile list.\n\nObservations:\n- DNS resolves and HTTPS 200: app, auth, demo, docs, login, oauth (307? Actually status 307ERR due to HEAD redirect maybe), proof.internal, qa, session-inspector.internal, status, trust, unleash.internal, www. Also maybe oauth 307 ERR means HTTPS returned 307 but curl -I -L maybe failed? Let's parse. `oauth.concept.dev` DNS cname.workos-dns.com, HTTPS:307ERR. `curl -sI -L ...` returned `307ERR`? Wait format is `%{http_code}` plus `|| echo ERR`. The output `307ERR` means `%{http_code}` printed `307` and then `|| echo ERR` also appended? That can't happen because `||` only runs if curl exits non-zero. But `curl -sI -L -w '%{http_code}'` may exit 0 and print 307. Then `|| echo ERR` should not. Actually output `307ERR` suggests status code string from curl is `307` but then ERR added? Maybe the `printf` line: `printf ... HTTPS:%s` \"$status\"` where `$status` contains `307` from curl and then `ERR` from fallback? Wait if curl fails with exit non-zero, we `echo ERR`. That would set status to just `ERR`, not `307ERR`. Unless `curl` printed `307` to stdout and then `||` appended `ERR`? No. The command `status=$(curl ... || echo ERR)` captures either curl's stdout or ERR. The output `307ERR` indicates curl stdout was `307` and echo ERR also appended? But in command substitution, `||` with `echo ERR` would replace the entire output. Hmm. Maybe `curl -w '%{http_code}'` printed `307` and then exited nonzero; `||` appended `ERR` but the command substitution output would be `307` plus `ERR`? Let's recall: `$(cmd1 || cmd2)` runs cmd1, if fails runs cmd2, and the output of the whole substitution is the output of whichever command ran. If cmd1 prints `307` to stdout and then cmd2 prints `ERR`, the substitution output is `307` and `ERR`? Actually in a subshell, if cmd1 fails, the shell still runs cmd2. The stdout of both could be captured, but cmd2 runs after cmd1. If cmd1 prints `307` then fails, cmd2 prints `ERR`, total output `307ERR`. Yes. So oauth returned HTTP 307 from HEAD but curl considered it a failure? Possibly because `-L` following a redirect with HEAD unsupported? Or maybe `--max-time`. So we need treat oauth as live (DNS resolves and HTTP responds with 307). Also `arena.internal.concept.dev` HTTPS:000ERR means curl didn't connect or returned no status (maybe cert error or connection refused). But DNS resolves. `demo-api` 404, `admin` 404, `api` 404, `filbert` 404, `qa-api` 404, `qa-oauth` 404, `v` 404: these are live (server responds) though 404. `oauth` 307 is live. `arena.internal` 000ERR maybe not reachable via HTTPS but DNS exists; could be a service not serving HTTPS or blocked. Need maybe check HTTP not HTTPS or check port 443. But for \"live\" maybe DNS is enough? We can mention both categories.\n\nNeed to present a clear list of live subdomains. The user likely wants to know which are currently active. We can categorize:\n\nLive (DNS resolves + HTTPS response):\n- 200: app, auth, demo, docs, login, proof.internal, qa, session-inspector.internal, status, trust, unleash.internal, www\n- 404 (server up but page not found): admin, api, demo-api, filbert, qa-api, qa-oauth, v\n- 307 redirect: oauth\n- DNS only / HTTPS failed: arena.internal (resolves to 35.244.252.201 but HTTPS didn't respond)\n\nAlso internal.concept.dev, liquidr.staging, staging-api, staging-app, workspace*, workspace all NXDOMAIN.\n\nLet's maybe also verify with HTTP (not HTTPS) for arena.internal and oauth? Could be `arena.internal.concept.dev` is internal and not publicly accessible; HTTPS may require client cert or block. `000ERR` likely connection refused/timeout. Could try `http://` or `curl -k`? Maybe not. The user didn't ask for deep debugging. We can present.\n\nMaybe should also mention that crt.sh is currently returning 502, so list from earlier cache. Actually we can mention that. But the user said \"figure out which ones are live\" not \"which from crt.sh\". Could note crt.sh is down at the moment, but we used the prior list.\n\nBetter to create a nice table. Since terminal output already has table. Could just summarize live list. Also the earlier output included `cname.workos-dns.com.` for admin, auth, login, oauth, qa-oauth. It says `DNS:cname.workos-dns.com. -> cname.workos-dns.com.` which is weird; CNAME record points to cname.workos-dns.com and no A? Actually `dig +short A` returns nothing and `dig +short CNAME` returns `cname.workos-dns.com.`; then ip empty. We set dns to `$ip${cname:+ -> $cname}` with ip empty, so ` -> cname.workos-dns.com.` Actually output shows `DNS:cname.workos-dns.com. -> cname.workos-dns.com.`? Wait, the output for admin: `DNS:cname.workos-dns.com. -> cname.workos-dns.com. HTTPS:404`. Let's inspect the script: `dns=\"$ip${cname:+ -> $cname}\"`. If ip is empty, dns is ` -> cname.workos-dns.com.` But output shows `cname.workos-dns.com. -> cname.workos-dns.com.`. That suggests `ip` variable got the CNAME content? Wait `ip=$(dig +short A \"$h\" | head -1)`. For admin.concept.dev, `dig +short A` might return the CNAME target and A?

We should improve: extract actual IP (last line) or use `dig +short A +noshort`? Let's parse better. But for final answer we can clean up. The current output is enough, but maybe we want a cleaner summary. We can re-run with improved parsing: use `dig +short A` and take the last line as IP, or if only CNAME no A, use cname. But we already have enough info. However, to give a good final answer, we should maybe regenerate a cleaner table. Since user wants \"figure out which ones are live\". We can provide categories. The previous table is okay but can be confusing. Let's re-run with a more robust script that:\n- Fetches list from file (or hardcode).\n- For DNS: get CNAME and A.

not a typo on your end — it has no DNS record right now, along with the other `workspace-*` subdomains.","tool_calls":[],"thinking":"Great, more complete. Need produce final answer. We can categorize:\n\nDNS resolves + HTTPS response:\n- 200 OK: app, auth, demo, docs, login, qa, status, trust, www (note www redirects to concept.dev, status 301 but response)\n- 404 (server responds): admin, api, demo-api, filbert, qa-api, qa-oauth, v\n- 302/307 (redirects): oauth (307 -> workspace-api...), proof.internal (302 -> Google OAuth), qa-oauth (307 -> qa-api...), session-inspector.internal (302 -> Google OAuth), unleash.internal (302 -> Google OAuth)\n- DNS only but no HTTP/S response: arena.internal (35.244.252.201) - maybe non-web host/firewalled\n\nNXDOMAIN (not live): internal, liquidr.staging, staging-api, staging-app, workspace*, workspace\n\nWe should be concise and maybe present a table. Also mention crt.sh currently 502, but used earlier list. Not necessary. Since output is long due to Location headers, we should summarize, not dump full Google OAuth URLs unless useful. We can note that several internal services redirect to Google IAP OAuth.\n\nNeed also consider `arena.internal` HTTPS:http:000 means HTTP also 000. It resolves but no web server. Could be alive but not web. Mark as \"DNS resolves, no web port\".\n\nAlso `docs.concept.dev` IP 104.21.89.241? Wait earlier docs was 172.67.192.26? The second run shows docs 104.21.89.241. Cloudflare anycast, IPs rotate. Fine.\n\n`www` returns 301 to concept.dev (live). `status` 200. `trust` 200. `app`, `auth`, `demo`, `login`, `qa` 200. \n\n`oauth` 307 to `workspace-api.concept.dev/mcp/oauth/login` but workspace-api NXDOMAIN. That means oauth is accessible but its redirect target isn't public. `qa-oauth` 307 to `qa-api.concept.dev/mcp/oauth/login` and qa-api is 404 (server responds). Wait qa-api 404. So qa-oauth redirects to qa-api, which returns 404? But redirect is at /mcp/oauth/login; status from qa-oauth was 307. Good.\n\n`proof.internal` and `session-inspector.internal` and `unleash.internal` all redirect to Google OAuth (IAP). So they are protected.\n\n`arena.internal` resolves to 35.244.252.201 (Google Cloud) but no HTTP response. Could be a VM with SSH or something. We can mention.\n\nLet's structure answer. Could include two sections: Live (DNS + responds) and Not live (NXDOMAIN). Under Live, subcategories 200, 30x, 404. Mention that 404s are still live servers. Provide a compact list.\n\nShould we include the raw table? It's a bit verbose with long URLs. Better summarize. But the user might appreciate raw. We can include a markdown table with Host, DNS, HTTPS. But the Location URLs are huge; can omit or truncate. Simpler: bullet list.\n\nNeed ensure we don't accidentally expose sensitive info. The Google OAuth URLs include client_id and state; not secret but could be considered. It's public because server redirects to it. Still, maybe avoid dumping full URLs. We can say \"redirects to Google OAuth/IAP\" without full URL. That's more responsible. The `oauth` redirect to workspace-api includes no sensitive info? It includes path. Could mention.\n\nLet's prepare final answer. Also note that \"live\" is based on DNS and a quick HTTPS check, so services on non-standard ports or IP-restricted won't appear.\n\nMaybe also mention `www` redirects to apex. `trust` uses Vanta. `status` is on Cloudflare.\n\nLet's formulate.","created_at":"2026-07-14T23:41:56.611529Z","finish_reason":"stop","metrics":{"ttft_ms":723,"total_time_ms":3643,"input_tokens":4629,"output_tokens":1278,"cache_read_tokens":29056,"cache_creation_tokens":null,"tpot_ms":2.2848200312989047,"tokens_per_sec":437.67123287671234}},{"message_id":"1d28a653-0671-4cda-afb0-fb35d7b7a7f8","node_id":109,"role":"user","content":"diagnose these, figure out how they work Server responds with 404 (live, but no root page)\n\n • admin.concept.dev\n • api.concept.dev\n • demo-api.concept.dev\n • filbert.concept.dev\n • qa-api.concept.dev\n • qa-oauth.concept.dev\n • v.concept.dev","created_at":"2026-07-14T23:42:48.424734Z","finish_reason":null,"metrics":null},{"message_id":"bf3b3d50-2fff-46e7-ade9-83901c619721","node_id":111,"role":"assistant","content":"","tool_calls":[{"id":"functions.exec:25","name":"exec","arguments":{"command":"cat > /tmp/diag.sh << 'EOF'\n#!/bin/bash\nhosts=\"admin.concept.dev api.concept.dev demo-api.concept.dev filbert.concept.dev qa-api.concept.dev qa-oauth.concept.dev v.concept.dev\"\nfor h in $hosts; do\n echo \"===== $h =====\"\n curl -sS -D - -o - --max-time 8 \"https://$h/\" 2>&1 | head -80\n echo\ndone\nEOF\nbash /tmp/diag.sh","idle_timeout":60000,"timeout":120000}}],"thinking":"The user wants to diagnose the subdomains that returned 404, figure out how they work. Need to probe each: check HTTP methods, paths, response headers, body, CORS, API endpoints, robots, swagger, openapi, health. Determine whether they are APIs, admin panels, etc. Could use curl to fetch root, common paths, and inspect headers.\n\nWe should be careful: probing live systems owned by concept.dev. This is authorized? User likely has permission (they are checking their own domain? Not explicit, but since they are diagnosing their own subdomains). It's defensive recon. We can help.\n\nNeed to produce diagnostic info: For each host, what kind of service, framework, endpoints, redirects, auth, etc. We can run curl with verbose on root and some common paths: /, /health, /api, /swagger, /openapi.json, /graphql, /admin, /v1, /version, /robots.txt, /.well-known/security.txt. But many requests; to keep low-effort, perhaps do a quick curl on root with -i to see headers and body, plus /health and /openapi.json or /api. Then infer.\n\nWe can script a diagnostic across the 7 hosts. Could also use `curl -sD - -o /dev/null` to get headers. Use `-A` with a browser user-agent? Use `-L`? For root returned 404. Maybe some require a path. Let's examine response headers and body for each root. Then try a few paths.\n\nWe can use `curl -s -D - https://host/` and capture body. The body might be JSON 404 or HTML. From headers: Server, Content-Type, `X-Powered-By`, `CF-RAY`, `alt-svc`. The IP can hint at hosting provider. `api.concept.dev` resolved to 8.233.251.240 (Cloudflare? Actually 8.x is not Cloudflare? 8.233.x is Cloudflare? Cloudflare IPs are 104, 172, sometimes 8.x? Cloudflare owns 8.0.0.0/8? Not typical; maybe it's a proxy. `api.concept.dev` 404). `demo-api` 136.110.212.49 (maybe Google Cloud or other). `filbert` 35.227.247.54 (Google Cloud). `v` CNAME to proxyhog (Cloudflare? cf-prod-us-proxy.proxyhog.com -> 104.20.19.245). `qa-api` 8.233.118.247. `qa-oauth` CNAME workos-dns. `admin` CNAME workos-dns -> Cloudflare (172.64.152.23). Need to probe.\n\nLet's first get root headers and body for all 7. Use a script with `curl -sS -D - -L --max-time 8`? But -L might follow redirects, for 404 none. Use `curl -sS -D - -o - https://$h/`. This prints headers and body. Might be long. We'll capture.

The app JS uses relative paths `/api/v1/...`. Since the app is served from `app.concept.dev`, the API calls go to `https://app.concept.dev/api/v1/...`. But `app.concept.dev` is a static frontend on Google Frontend. Does it proxy API requests to `api.concept.dev`? Let's test `https://app.concept.dev/api/v1/auth/config` vs `https://api.concept.dev/api/v1/auth/config`. The relative API path may be proxied by the same host (reverse proxy). Let's test. Also the API endpoints discovered: auth, workspaces, concepts, connectors, billing, transcribe, telemetry, etc. The product \"Concept\" appears to be a workspace/platform builder.\n\nNeed to determine which of the 404 domains correspond to which API. `api.concept.dev` is production API, `demo-api` and `qa-api` are environment APIs. But the frontends call relative `/api/v1/...` on `app`, `demo`, `qa`. So each environment likely proxies to its corresponding API (`demo` -> `demo-api`, `qa` -> `qa-api`, `app` -> `api`). We can verify by hitting `https://demo.concept.dev/api/v1/auth/config` and seeing if it returns a config JSON. Also `https://api.concept.dev/api/v1/auth/config`. If the API root is `/api/v1`, our earlier probes didn't include that prefix. That explains all 404.

Wait in GLSL, you can assign to an undeclared variable? No, if `ADD_HELPERS` is not defined, the preprocessor removes those lines, so no issue. Good.\n\nNeed to create the standalone HTML. Let's write the file. Need to include the vertex shader from `shader-mount.js` and fragment shader from `AuthBackground.js` with helper strings inserted. We have the vertex shader lines 1-151. The fragment shader lines 1-270 with `${M}` etc. Need to replace placeholders with actual helper code. The `${s.maxColorCount}` -> `7`. The `${M}` etc.\n\nLet's extract vertex and fragment from files with a script to avoid manual transcription. We can parse using Python. Use `sed`? Let's write a Python script to generate `index.html` from these files. It will:\n\n- Read `/tmp/shader-mount.js`, extract the vertex shader string `I` (starts with `#version 300 es` and ends before `,A=...`). The file line 1 begins `const I=\\`#version 300 es...` and the shader ends before `\\`,A=1920*1080*4;`. We can split on `\\`,A=`.\n- Read `/tmp/auth-background.js`, extract fragment shader `N` (starts with `const N=\\`#version 300 es` and ends before `\\`,W={wave:...`). Then replace placeholders:\n - `${M}` with the `J` string from shader-mount (defines). Need extract `J` string: `const J=\\`...\\`;`? Actually in shader-mount, `J` is the defines: `const J=\\n#define TWO_PI...\\n`; Wait the file line 168? Let's see. The shader-mount.js tail shows `J=\\n#define TWO_PI...`? Actually earlier in read, after `oe`, it says `;function se`. Before `function se` there is `oe` string. The `J` variable is defined earlier? Wait the exports line maps `J as d`. In the file, `const I` is vertex, then `A`, `D` class, then later `J`, `ee`, `te`, `ie`, `re`, `oe`. The `J` is the defines. In read output, after class `D` CSS, line 168 starts `,Q={none:0,contain:1,cover:2},J=\\n#define TWO_PI...`. Wait the read shows line 168: `},Z={fit:\"contain\",...},Q={...},J=\\n#define...`. Actually read:\n\n```\n168|}`,A=1920*1080*4;let D=class{... [class] ... 168? Actually the read line 168 is the CSS closing and then J.\n169|#define TWO_PI 6.28318530718\n170|#define PI 3.14159265358979323846\n171|`,\n```\n\nSo `J` string is `#define TWO_PI ... \\n#define PI ... \\n`. Good.\n\n- `x` = snoise (`oe` string)\n- `v` = rotate (`ee` string)\n- `S` = randomR (`re` string)\n- `k` = hash11 (`te` string)\n\nNeed to extract these strings from shader-mount.js. They are top-level `const J=...`, `const ee=...`, `const te=...`, `const ie=...`, `const re=...`, `const oe=...`. We can parse with regex. They are backtick strings, no nested backticks. Use regex `const (J|ee|te|ie|re|oe)=\\`([\\s\\S]*?)\\`;`. The file may have backticks inside? The strings are GLSL with no backticks. Good.\n\nFor AuthBackground fragment `N`, parse `const N=\\`([\\s\\S]*?)\\`,W={wave:`. Then replace `${M}` with `J` content, `${x}` with `oe` content, `${v}` with `ee` content, `${S}` with `re` content, `${k}` with `te` content, and `${s.maxColorCount}` with `7`.\n\nVertex shader `I` parse `const I=\\`([\\s\\S]*?)\\`,A=`.\n\nThen write `index.html` with these shaders and JS.\n\nLet's write Python script to generate.","created_at":"2026-07-14T23:48:38.743376Z","finish_reason":"tool_calls","metrics":{"ttft_ms":1189,"total_time_ms":8615,"input_tokens":5751,"output_tokens":3506,"cache_read_tokens":92160,"cache_creation_tokens":null,"tpot_ms":2.1180832857957785,"tokens_per_sec":472.1249663345004}},{"message_id":"5d1e3e6c-23ea-42aa-8f8c-1101f2e6fca4","node_id":650,"role":"tool","content":"Output from command in shell 34589f:\nTraceback (most recent call last):\n File \"\", line 9, in \nAttributeError: 'NoneType' object has no attribute 'group'\n\n\nExit code: 1","created_at":"2026-07-14T23:48:38.814012Z","finish_reason":null,"metrics":null},{"message_id":"c4117ee8-7fa7-4c56-bd62-f39b0ed477fd","node_id":651,"role":"assistant","content":"","tool_calls":[{"id":"functions.exec:97","name":"exec","arguments":{"command":"head -c 500 /tmp/shader-mount.js | cat -v","timeout":15000}}],"thinking":"Regex didn't match.

Maybe Python string escaping issue: `rf'const {name}=`([\\\\s\\\\S]*?)`'` double escaping? In raw string, `\\\\s` is two chars `\\s`? Actually `r'...'` with `\\\\` yields a literal backslash then s? Wait raw string `r'\\s'` is backslash-s. `r'\\\\s'` is two backslashes then s, which when used as regex becomes `\\\\s`? That would be literal backslash then s, not whitespace. We need `\\s` in regex. Since we wrote `r'const I=`([\\\\s\\\\S]*?)`,A='`, the regex is `const I=`([\\\\s\\\\S]*?)`,A=`. In regex, `\\\\s` means literal `\\s`? Actually in a regex string, `\\s` is an escape for whitespace. `\\\\s` is an escaped backslash followed by `s`, which is literal `\\s`? Wait the Python `re` module receives the string `const I=`([\\\\s\\\\S]*?)`,A=`. The regex engine sees `\\\\` as a literal backslash? Actually in regex, `\\\\` matches a literal backslash. Then `s` matches s. So `[\\s]`? No, `\\\\s` inside a character class? The pattern is `[\\s\\S]`. To represent `\\s` in the regex string, we need `r'[\\s\\S]'` or `'[\\\\s\\\\S]'`. With raw string `r'[\\s\\S]'` gives `\\s\\S` in pattern. We wrote `r'... [\\\\s\\\\S] ...'`. Since it's raw, `\\\\` is two backslashes. So pattern contains `[\\\\s\\\\S]`, which in regex means a character class containing `\\`, `s`, `\\`, `S`? Actually inside a character class, `\\\\` is literal backslash, then `s` and `S` are literal. That's not correct. We need `[\\s\\S]`. So remove one backslash in raw strings. Use `r'const I=`([\\s\\S]*?)`,A='`. Similarly for helpers.

It had hash21. Good. But `re` length 116 (randomR). `oe` 904 (snoise). `J` 64 (defines). `ee` 93 (rotate). `te` 112 (hash11). All good.\n\nNow regenerate HTML with correct regex. Also need ensure writing to `/tmp/concept-shader/index.html`. Need create directory. Also note the `replace('`', '\\\\`')` etc inside template literal generation: In the Python string, we need to output JavaScript template literal with backticks. For each shader source, we embed inside a JS template literal delimited by backticks. If the shader source contains backticks, none (GLSL uses no backticks). But `replace('\\\\', '\\\\\\\\')` needed? The shader source doesn't contain `\\` except maybe `\\\\`? It doesn't. But we can escape backslashes just in case. However, `fragment.replace('\\\\', '\\\\\\\\').replace('`', '\\\\`')` in Python string will produce e.g. `\\\\` -> `\\\\\\\\` in HTML, which is over-escaping? In JS template literal, a single backslash is fine, but `\\n` in template literal is newline. We don't want that? Wait in JS template literals, `\\n` is a newline, and actual newlines are allowed. The shader source has actual newlines from the file. If we do `fragment.replace('\\\\', '\\\\\\\\')`, it will double any backslashes in the GLSL. The GLSL has `\\\\`? Not in shader code (only `//` comments). It has no `\\n` string. It has `\\\\`? In `#version 300 es` no. So `replace('\\\\', '\\\\\\\\')` is safe.\n\nBut the bigger issue: The shader source string is inserted into Python triple-quoted string `const fragmentSource = `''' + fragment + '''`;`. The Python string uses triple single quotes, which can contain newlines and backticks. The JavaScript code then has `const fragmentSource = `...`;`. The `...` contains the GLSL with newlines, which in a JS template literal is fine. It may contain `${` which would be interpreted as template literal interpolation. The GLSL contains `${...}`? Yes! The AuthBackground fragment shader still contains `${s.maxColorCount}`? We replace that. But also the helper strings may contain `${`? The defines `J` just has `#define`, no. `snoise` no. `randomR` no. `rotate` no. `hash11` no. `hash21` no. Good.\n\nBut the fragment shader from AuthBackground uses `${M}` etc. We replaced them. Ensure no remaining `${` in the combined shader. Check with regex. If any, JS template literal would try to interpolate undefined variables. We can escape them as `\\${`. But since none expected, fine.\n\nHowever, the vertex shader `I` from shader-mount might contain `${`? It doesn't. Good.\n\nAlso the Python triple-quoted string ends with `''';` which could conflict if the shader contains `'''`? It doesn't.\n\nNeed create directory.

Hmm. Actually shape 6 (blob) might be small at t=0.7 and with offset/scale it could be offscreen. Wait earlier when we tested `debug.html` with shape 6, average was also background. The blob branch: `t *= 2;` and trajectories; at t=0.7, positions maybe near edges? But the shape uses `shape_uv` which is `v_objectUV` (range -0.7 to 0.9). The blob trajectories are around 0.2-0.3, so should be visible. But `shape` uses `length(shape_uv + f1_traj)` and `pow(1 - clamp(...), 5)`. If `shape_uv + f1_traj` length > 1, term 0. At t=0.7*2=1.4, f1_traj = .25*vec2(1.3*sin(1.4), .2+1.3*cos(.84+4)) = .25*vec2(1.3*0.985, .2+1.3*cos(4.84)) = .25*vec2(1.28, .2+1.3*0.13)=.25*vec2(1.28,0.37)=vec2(0.32,0.09). That's within [-0.7,0.9]. Should produce a blob. But maybe the `smoothstep(.0,.9,shape)` and `edge` threshold make it 0 if shape < 0.3? Not. Hmm. Maybe `shape_uv` is too large or too small? Wait `shape_uv = v_objectUV`. For contain fit, `v_objectBoxSize` = min(res) = 600? Wait window 800x600, res drawing buffer 800*dpr x 600*dpr (dpr=1 in headless? SwiftShader maybe dpr=1). `v_objectBoxSize` = min(800,600)=600. `objectWorldScale` = (800/600, 600/600) = (1.333,1). `uv` range [-0.5,0.5]. `v_objectUV` = uv*(1.333,1) / 1.1 + (.12,-.18)/1.1. So range x: (-0.667+0.109, 0.667+0.109)=(-0.558,0.776), y: (-0.5-0.164,0.5-0.164)=(-0.664,0.336). The blob trajectories around (0.32,0.09) are within. But `length(shape_uv + f1_traj)` for shape_uv around (0.32,0.09) + (0.32,0.09) = length(0.64,0.18)=0.665. `1-clamp(0,1,0.665)=0.335`, pow^5 = 0.004. That times .5 = 0.002. For shape_uv = (-0.32,-0.09)+ (0.32,0.09) = 0, length 0, term .5. So shape around the trajectory center could be up to .5. Then `smoothstep(.0,.9,shape)` maps .5 to ~0.48, edge `smoothstep(.25,.3,shape)` maps .5 to 1, so shape stays .48. Then `shape` output ~0.48. After `shape = clamp(shape - .5/u_colorsCount,0,1)` with u_colorsCount=4, threshold .125, shape .355. `totalShape = smoothstep(0, softness+2*aa, clamp(shape*4,0,1))` = smoothstep(0, .62+aa, 1.42) ≈ 1. So it should be visible. Why average background? Maybe because `u_shape` uniform for shape 6 is set to 6.0 but the fragment uses `u_shape < 6.5`, so it should hit blob. Unless `u_shape` is not set because `shapeValue` is 6.0 but `gl.uniform1f` not working? But shape 1-5,7 produce different averages, so `u_shape` is set. Hmm. Shape 7 sphere also visible. Shape 6 blob maybe not visible due to offset/scale making the blob offscreen? Let's check shape 6 visually. Use `read` or convert. But we can't see. Maybe open image? Let's open all images with `open` and maybe use `background-computer-use` to take a screenshot? Not needed for final. But we should ensure shape 6 image is not broken. The file size is 146K, not tiny, but average background. Could be the blob is dark and blends? Wait average [9,26,51] is exactly background, so no shape. That's odd.

Maybe blob shape is broken in the original? Or the `u_shape` 6 branch has a bug? Wait the original `AuthBackground` uses shape 4 (corners). The blob branch maybe never used in production. It could be that the `shape_uv` for blob is too large or the `t *= 2` makes trajectories too large. Let's compute at t=10*0.1? Wait `u_time` at virtual budget 10s = performance.now() ~10000? The shader `t = .1 * (u_time + 7)`. `u_time` = now * 0.001 = 10. So t = .1*(10+7)=1.7. Blob branch `t *= 2` => 3.4. f1_traj = .25*vec2(1.3*sin(3.4), .2+1.3*cos(2.04+4)) = .25*vec2(1.3*(-0.26), .2+1.3*cos(6.04)) = .25*vec2(-0.34, .2+1.3*0.97)=.25*vec2(-0.34,1.46)=vec2(-0.085,0.365). For shape_uv in [-0.5,0.7]x[-0.6,0.3], `shape_uv + f1_traj` length can be 0 at (-0.085, -0.365) which is within y range? y -0.365 is within [-0.664,0.336]. So should produce blob. Hmm.\n\nWait maybe `shape_uv` is `v_objectUV` which for blob branch `u_shape > 3.5` uses `shape_uv = v_objectUV; grain_uv = shape_uv;`. Yes. But `v_objectUV` values maybe not what I thought. Let's inspect `v_objectUV` calculation for `u_fit=1` contain, `u_scale=1.1`, `u_offsetX=-.12`, `u_offsetY=-.18`, `u_originX=.5`, `u_originY=.5`, `u_resolution=(800,600)`, `u_worldWidth=0`, `u_pixelRatio=1`.\n\n`givenBoxSize = max(vec2(0,0), vec2(1)) * pixelRatio = vec2(1,1)`. \n`fixedRatioBoxGivenSize = (res.x, 1) = (800,1)`. \n`fixedRatio = 1`. `getBoxSize(1, (800,1))`: `box.x = 1 * min(u_resolution.x / 1, u_resolution.y)` because `u_fit=1` => `min(800,600)=600`. `box.y=600`. `v_objectBoxSize=(600,600)`. `objectWorldScale = (800/600, 600/600) = (1.333,1)`. `uv = gl_Position.xy * .5 = [-0.5,0.5]`. `boxOrigin = (.5-.5, .5-.5) = (0,0)`. `v_objectUV = uv * (1.333,1) + (0,0)*(scale-1) + (-offsetX, offsetY)? Wait `graphicOffset = vec2(-u_offsetX, u_offsetY) = (0.12, -0.18)`. `v_objectUV = uv * objectWorldScale + boxOrigin*(objectWorldScale-1) + graphicOffset;` then `/= u_scale`. So `v_objectUV = (uv*(1.333,1) + (0.12,-0.18)) / 1.1`. Range x: (-0.667+0.12)/1.1 = -0.497, (0.667+0.12)/1.1=0.716. y: (-0.5-0.18)/1.1=-0.618, (0.5-0.18)/1.1=0.291. So my earlier range correct. Blob center at (-0.085,0.365) has y 0.365 outside y max 0.291. Wait f1_traj y = 0.365 > 0.291, so the center is above canvas. To get `shape_uv + f1_traj = 0`, shape_uv = (0.085, -0.365), which is below y min -0.618? No, -0.365 is above -0.618, within range. Wait shape_uv needed is (0.085, -0.365) to cancel f1_traj. That's within x [-0.497,0.716] and y [-0.618,0.291]. Yes. So some pixel should have shape ~0.5. But `shape` uses `clamp(0.,1., length(...))`. If length <=1, term is `1-length`, pow5. At center, length=0, term .5. At distance 0.2, `1-0.2=0.8`, pow5=0.327, term .164. At distance 0.4, `0.6^5=0.078`, term .039. So shape falls quickly. The blob radius maybe 0.2-0.3 in `shape_uv` units. That is small but should be visible.\n\nBut average remains background. Maybe the issue is the `shape` values are below `0.5 / u_colorsCount` threshold? Wait `shape` after summing 4 blobs can be up to ~0.5 (only one blob dominates). Subtract .125 -> .375. `clamp(shape*4,0,1)` = 1.5. `smoothstep(0, .62 + 2*aa, 1.5)` ~1. So totalShape ~1. Then gradient uses mixer=shape*(u_colorsCount-1)=0.375*3=1.125. For colors 0 and 1, localT=1.125-0=1.125 clamped 1, so color = color[1]. For colors 1 and 2, localT=0.125, smoothstep around .5 -> ~0. So gradient ~color[1]. So output should be color[1] (#2f5391) at those pixels. Not background.\n\nSo why background? Let's test by hardcoding `u_shape` to 6 in the fragment shader and capturing. If it works, the problem is `shapeValue` for 6 not being passed. But we saw averages for 1-5,7 differ. Wait shape 1 average [157,167,181] (light), shape 2 [34,54,84], shape 3 [56,76,108], shape 4 [74,94,124], shape 5 [39,61,96], shape 7 [86,103,129]. They differ. For shape 6, if uniform was not set, it would default to 0 and go to `u_shape < 1.5` (wave) or maybe `else` at end? If `u_shape` is 0, `u_shape < 1.5` true -> wave. Wave at t=1.7 could be background? Actually wave branch: `shape = 1. - smoothstep(-1., 1., shape_uv.y + wave)`. At t=1.7, wave amplitude `(.75 + .25*cos(10.2))` = .75+.25*(-0.7)=0.575. `wave` product maybe small. `shape_uv.y` range [-0.6,0.3]. `shape_uv.y + wave` can be between -1.5 and 1.0, so `smoothstep` gives values from 0 to 1, shape maybe 0-1. Some pixels have shape > .125, so not background. But wave average could be background if wave is zero? Not exactly.\n\nMaybe `u_shape` for 6 is set but the blob branch is broken because `shape_uv` is `v_objectUV` and the `if (u_shape > 3.5)` branch only sets `shape_uv = v_objectUV` and `grain_uv = shape_uv`. The `else` branch (for shape <=3.5) uses `v_patternUV`. For shape 6, it enters `if (u_shape > 3.5)`. That's correct. But then the `else if (u_shape < 6.5)` branch should be taken. If `u_shape` is 6, yes. So why background?\n\nCould be `u_shape` is an integer? No, it's float. `parseFloat('6')` = 6.0. `gl.uniform1f` sets 6.0.\n\nMaybe the blob branch produces shape < threshold for all pixels due to `t *= 2` and trajectories making all blobs offscreen. Let's check f1-f4 trajectories at t=1.7 (blob branch t=3.4):\n- f1: .25*(1.3*sin(3.4), .2+1.3*cos(2.04+4=6.04)) = .25*(1.3*(-0.255), .2+1.3*0.969) = .25*(-0.332,1.46)=(-0.083,0.365). As above.\n- f2: .2*(1.2*sin(-3.4), 1.3*sin(5.44)) = .2*(1.2*0.282,1.3*(-0.79)) = .2*(0.338,-1.027)=(0.068,-0.205). That is within range.\n- f3: .25*(1.7*cos(-2.04), cos(-5.44)) = .25*(1.7*(-0.457),0.663)=(-0.194,0.166). Within.\n- f4: .3*(1.4*cos(2.72), 1.2*sin(-2.04)) = .3*(1.4*(-0.912),1.2*(-0.896))=(-0.383,-0.323). Within.\n\nTo get shape from f2, need shape_uv = -f2 = (-0.068,0.205). y=0.205 within y max 0.291. So there is a visible blob. Hmm. So why background?\n\nMaybe `shape_uv` for `u_shape > 3.5` is `v_objectUV` but `v_objectUV` may be huge due to `objectWorldScale`? Wait `objectWorldScale` for `fixedRatioBoxGivenSize = (res.x, 1)` with fit contain gave box size 600x600, scale (1.333,1). That's okay. But if `u_worldWidth=0` and `u_worldHeight=0`, `givenBoxSize = (1,1)*pixelRatio`, but `fixedRatioBoxGivenSize.y = (u_worldHeight==0) ? u_resolution.y : givenBoxSize.y = 600`. So box y = 600. Good.\n\nBut wait `u_pixelRatio` in SwiftShader headless may be 1? CSS size 800x600, canvas width 800, height 600. `u_resolution` = (800,600). Good.\n\nLet's actually read pixel color of shape_6.png to see if any non-background pixels.","created_at":"2026-07-14T23:53:21.593292Z","finish_reason":"tool_calls","metrics":{"ttft_ms":2510,"total_time_ms":9221,"input_tokens":1540,"output_tokens":2614,"cache_read_tokens":129024,"cache_creation_tokens":null,"tpot_ms":2.5673297628156084,"tokens_per_sec":389.50976009536583}},{"message_id":"e29af397-14a5-4fb8-bbec-b874c387eeba","node_id":748,"role":"tool","content":"Output from command in shell 9cb752:\n:5: DeprecationWarning: Image.Image.getdata is deprecated and will be removed in Pillow 14 (2027-10-15).

A generic WebGL2 React wrapper: `ShaderMount`\n\n`assets/shader-mount-DLdhuSwu.js` is the engine. It:\n\n- Creates a WebGL2 canvas\n- Compiles a fixed vertex shader + a user-supplied fragment shader\n- Sets up a fullscreen quad\n- Handles `devicePixelRatio`, resize observers, and `requestAnimationFrame`\n- Maps JS uniforms to GLSL: `u_time`, `u_resolution`, `u_pixelRatio`, plus arbitrary user uniforms like colors, scale, rotation, images/textures\n- Supports noise textures, mipmaps, and image uniforms\n\nSo the creators don’t write a new WebGL bootstrap for every background — they just write a new fragment shader and pass it to ``.\n\n## 2. The vertex shader is generic\n\nIt computes several UV spaces (`v_objectUV`, `v_patternUV`, `v_responsiveUV`, `v_imageUV`) so the fragment shader can choose whether to treat the pattern as a fixed-ratio object, a responsive container, a tiled pattern, or an image cover/contain. That’s why the same renderer can be reused for many different shader designs.\n\n## 3. The fragment shader is hand-written GLSL\n\n`assets/AuthBackground-BDcu6rNF.js` is the actual demo background. The fragment shader:\n\n- Uses `#version 300 es` WebGL2\n- Brings in helper functions: `snoise`, `fbm` (fractal Brownian motion), `valueNoiseR`, `hash11`, `rotate`, `truchet`\n- Has 7 shape branches selected by `u_shape`:\n - wave, dots, truchet, corners, ripple, blob, sphere\n- Uses `smoothstep` and fbm to create soft, animated gradient bands\n- Mixes through a color palette array `u_colors[7]` with `u_colorsCount`, `u_softness`, and `u_intensity`\n\nThe math is classic generative/ShaderToy-style GLSL: noise layering, domain warping, signed-distance-ish shaping, and color banding.\n\n## 4. A React component presets the look\n\n`AuthBackground` is just:\n\n```js\n\n```\n\nSo a designer/front-end dev can tweak colors and shape parameters without touching GLSL.\n\n## 5. Build tooling\n\nThe site is a Vite-built React SPA:\n\n- Hashed JS chunks: `index-CCRpWqwz.js`, `AuthBackground-BDcu6rNF.js`, `shader-mount-DLdhuSwu.js`\n- ES modules with relative imports\n- Static assets served from Google Frontend (likely Google Cloud Storage behind Cloudflare or a CDN)\n\n## In short\n\nThey made it by combining:\n\n- **React** for UI/component structure\n- **Vite** for bundling\n- **WebGL2 + hand-written GLSL** for the visuals\n- **A generic `` engine** so one background shader is a drop-in fragment string + uniforms\n- **Design tokens** for colors/transforms so the same shader can be themed across environments\n\nIt’s the same workflow you’d see on ShaderToy or in generative design tools, just packaged into a production React component.","tool_calls":[],"thinking":"The user asks: \"how did the creators make something like that?\" referring to the shader background. We should explain the pipeline/tools likely used. Based on the code we examined:\n\n- It's a React SPA built with Vite (assets with hash in filename, ES modules, import maps, `index-CCRpWqwz.js`).\n- The shader system is from `paper-shaders` or a similar design system? The CSS includes `[data-paper-shader]` and `paper-shaders` layer. The shader-mount class is likely from a library called `paper-shaders` or internal. The `AuthBackground` uses `@paper-shaders`? The CSS in shader-mount includes `:where([data-paper-shader])` and `@layer paper-shaders`. The JS uses `paper-shader` attribute. This is likely a custom/design-system package.\n- The WebGL renderer `ShaderMount` is a React component that takes a `fragmentShader` string and `uniforms`, compiles WebGL2, sets up a fullscreen quad, handles resize/dpr, supports images as uniforms, mipmaps, etc.\n- The GLSL fragment shader is handwritten: uses fbm, value noise, simplex noise, truchet, sine/cosine, smoothstep, and a multi-stop gradient. It has 7 shape options selected by `u_shape`. The uniforms control transform (origin, scale, rotation, offset, fit), colors, softness, intensity, noise.\n- The `AuthBackground` component wraps `ShaderMount` with default colors and shape \"corners\".\n- The workflow likely: a designer/frontend dev writes GLSL fragment shaders in template strings, builds with Vite, uses React to mount them.\n- The base64 noise texture is a small generated PNG used for `randomR`. They likely use a deterministic noise texture or a generated one.\n- The vertex shader is generic and computes multiple UV spaces (object, responsive, pattern, image) for the fragment shader to use.\n- Tools: React, TypeScript, Vite, custom WebGL2 component, GLSL shaders, possibly Figma/Design tokens for colors, and the `paper-shaders` design system (maybe internal).\n\nWe can also mention the architecture: separate `shader-mount` (generic engine) and `AuthBackground` (specific shader + presets). This separation makes it easy to add new backgrounds by writing a new fragment shader and passing uniforms.\n\nNeed keep it concise. Also mention that the heavy lifting is the fragment shader math (noise, domain warping, signed-distance-like patterns, color banding). The creators are comfortable with GLSL/WebGL.\n\nLet's craft answer.","created_at":"2026-07-14T23:57:15.494516Z","finish_reason":"stop","metrics":{"ttft_ms":1315,"total_time_ms":5326,"input_tokens":639,"output_tokens":1402,"cache_read_tokens":134272,"cache_creation_tokens":null,"tpot_ms":2.8609129814550642,"tokens_per_sec":349.53876838693594}},{"message_id":"81652f49-2986-4cc9-9d2d-0b1df63224a6","node_id":758,"role":"user","content":"make an animated website","created_at":"2026-07-15T00:27:53.081257Z","finish_reason":null,"metrics":null},{"message_id":"ae76799f-a973-4f61-be78-28c4d9dfb05d","node_id":759,"role":"assistant","content":"","tool_calls":[{"id":"functions.exec:148","name":"exec","arguments":{"command":"mkdir -p /Users/root1/animated-site && cp /Users/root1/concept-shader/index.html /Users/root1/animated-site/index.html && ls -la /Users/root1/animated-site/","timeout":15000}}],"thinking":"The user says \"make an animated website\". This is vague. They might want an animated website using the shader backgrounds we already made, or a new one. The context: we just extracted the Concept shader. They might want an animated website *like* that, or using those shapes. We should ask clarifying? But maybe they want us to create a small animated website demo on localhost using these shader options, perhaps with UI to switch shapes and colors. \"make an animated website\" could mean build a more complete site with the animated shader background, maybe a landing page. Given the conversation, let's interpret as: create an animated website (on localhost) showcasing the shader backgrounds with some interactive options. We already have `index.html` with shape query param. We can expand it into a nice landing page with the shader background and controls to switch between shapes and colors, plus some text overlay. This would be an \"animated website\".\n\nWe can create a new site directory `~/animated-site` or update `~/concept-shader` with a more polished page. Since the user asked \"make an animated website\" without specifics, we can create a single-page site with:\n- Fullscreen animated shader background (using the same WebGL code)\n- Overlay with title, subtitle, and buttons/cards to switch shapes\n- Smooth transitions? Changing shape uniform instantly changes animation; we can add a fade or just update uniform.\n- Maybe a music or particle effect? Not needed.\n- Use local server.\n\nWe should not overdo. But a nice animated landing page with shader background and controls fits. Let's create `~/animated-site/index.html` that includes the shader code (extracted) plus a UI. Or update `~/concept-shader/index.html` to be the animated website. The user said \"make an animated website\" singular. Maybe create `~/animated-site` separate from `concept-shader`. But we can reuse code.\n\nSince we already have the shader code in `~/concept-shader/index.html`, we can copy it to `~/animated-site/index.html` and add a UI. The JS currently reads `?shape=` query. We can make it interactive with buttons that set `u_shape` uniform. Also add some content (hero text). Use nice typography.\n\nPlan:\n1. Create `~/animated-site/index.html` based on `~/concept-shader/index.html` but with:\n - A UI overlay: title \"Concept Shader\", subtitle, a row of buttons/pills for each shape, maybe color picker.\n - Buttons call a function `setShape(n)`.\n - Add a color picker or preset buttons for color palettes.\n - Use CSS `mix-blend-mode` or just white text with text-shadow for readability.\n - Make the canvas cover the page.\n2. Serve on localhost (maybe port 8081 if 8080 occupied).\n3. Open in default browser (or just provide URL). We can open via `open http://localhost:8081`.\n\nNeed to ensure the shader code is included. Since `index.html` is self-contained with all JS inline, we can copy and modify. The file is ~18KB. We can read it, then use Python or edit. Simpler: copy `~/concept-shader/index.html` to `~/animated-site/index.html`, then edit to add UI.\n\nBut adding UI in the same file means injecting HTML and CSS and modifying JS. Could also create separate files, but the shader is inline. Let's just create a new `index.html` with the shader code and UI. We can write it using Python f-strings, reading the existing file and injecting UI.\n\nNeed to parse existing file and split at `` and ``. Add `
` with title, controls.

We need to create a new shader or modify the existing one to look like liquid metal. We can build on the existing shader framework. To get liquid metal, we can write a custom fragment shader (or adapt existing one) with:\n\n- Colors: metallic palette: dark gunmetal background, silver/chrome, white highlights.\n- Shapes: use sine/cosine interference, domain warping, noise to create flowing metallic reflections.\n- High specular-like highlights using smoothstep and pow.\n- Use simplex noise + fbm to distort coordinates, then create bands/highlight patterns.\n- Animate slowly.\n- Maybe use a shape value > 7? The existing shader only supports 1-7. We can add a new `u_shape` value 8 for \"liquid metal\" by modifying the fragment shader and adding a branch. Or create an entirely separate fragment shader in a new file `~/liquid-metal-site/index.html`.\n\nGiven the user wants \"the same thing but with a more liquid metal vibe\", easiest is to create a new site `~/liquid-metal-site/index.html` with the same UI but a custom liquid-metal fragment shader. We can reuse the shader-mount vertex shader and the helper functions. We'll write a new fragment shader in GLSL 300 es. The UI can have shape options specific to liquid metal or just one \"liquid metal\" mode plus maybe a few variations. But \"the same thing\" implies same controls (shape, palette, speed). We can keep the same UI and add a new shape \"Liquid Metal\" (shape 8) with the new fragment. Or replace all shapes with liquid-metal variations.\n\nSimpler: create a new page where the shader is always liquid metal, with controls for palette and speed (and maybe a \"turbulence\" or \"ridges\" parameter). But to match \"same thing\", keep shape buttons but make them different liquid-metal modes: e.g., Flow, Ripples, Mercury Pool, Chrome Waves. Let's design 4-5 liquid-metal styles in the fragment shader.\n\nWe need write the GLSL. Let's design a liquid metal fragment shader:\n\nUse the existing vertex shader and helpers (noise, fbm, rotate, random). The fragment shader inputs `v_objectUV`, `v_patternUV`, `v_objectBoxSize`, `v_patternBoxSize`.\n\nLiquid metal idea:\n- Distort UV with fbm and sine.\n- Compute a \"height\" field using multiple octaves of noise + sine waves.\n- Use that to mix between dark metal, mid silver, bright highlight, white specular.\n- Add moving reflections using rotated coordinates and time.\n- Use `pow` for shiny highlights.\n\nA classic chrome/liquid look:\n```\nfloat t = u_time * 0.15;\nvec2 uv = v_objectUV * 0.5;\n// domain warp\nfloat n = snoise(uv * 2.0 + t);\nuv += vec2(cos(uv.y*3.0+t), sin(uv.x*3.0+t)) * 0.15;\n// base pattern\nfloat p = sin(uv.x*4.0 + t + n) * cos(uv.y*4.0 - t);\np += 0.5 * sin(uv.x*8.0 - t*2.0);\np = p * 0.5 + 0.5;\n// ridges\nfloat ridge = abs(sin(p * 10.0 + t));\nridge = pow(ridge, 4.0);\n// mix colors based on p and ridge\nvec3 dark = vec3(0.05,0.05,0.07);\nvec3 mid = vec3(0.4,0.42,0.45);\nvec3 light = vec3(0.85,0.87,0.9);\nvec3 spec = vec3(1.0);\nvec3 color = mix(dark, mid, smoothstep(0.2,0.6,p));\ncolor = mix(color, light, smoothstep(0.5,0.8,ridge));\ncolor += spec * pow(ridge, 8.0) * 0.6;\nfragColor = vec4(color,1.0);\n```\n\nBut we want multiple \"shapes\" maybe. We can create a fragment shader with branches for shape 1-4:\n1. Flowing mercury (domain warped sine interference)\n2. Ripple pool (concentric ripples with noise)\n3. Chrome waves (diagonal sine with noise)\n4. Blobby metal (metaball-like blobs)\n\nUse existing helpers? We can include `snoise`, `fbm`, `rotate`, `hash` etc. For simplicity, we can just write one robust liquid-metal fragment and ignore shape selector or have a few variants.\n\nSince the user likely wants a visually impressive result, we can write a single high-quality liquid metal shader and the UI can switch between a few presets (color palettes and speed). But \"same thing\" suggests same structure. Let's create a new site `~/liquid-metal-site/index.html` with:\n- Full-screen WebGL2 shader background.\n- UI panel with \"Mode\" buttons (Flow, Ripples, Chrome, Blobs), \"Palette\" buttons (Mercury, Gold, Rose Gold, Cyber), speed slider.\n- Use the same vertex shader from before.\n- Write a new fragment shader for liquid metal.\n\nLet's create the fragment shader carefully. We'll use `#version 300 es`, `precision lowp float;`, uniforms: `u_time`, `u_resolution`, `u_pixelRatio`, `u_noiseTexture`, `u_colorBack`, `u_colors[4]`? Instead of colors array, we can have `u_baseColor`, `u_highlightColor`, `u_darkColor` etc. Or use `u_colors[4]` like before and interpret as dark/mid/light/specular. Simpler: define a palette in the fragment using `u_colors[4]` as:\n- colors[0] = dark base\n- colors[1] = mid metal\n- colors[2] = bright highlight\n- colors[3] = specular white\n\nThen `u_colorsCount` = 4. The mixing logic uses these. The original loop mixes colors based on shape gradient; we can repurpose but easier to just directly mix.\n\nLet's design the fragment shader:\n\n```\n#version 300 es\nprecision lowp float;\nuniform mediump float u_time;\nuniform mediump vec2 u_resolution;\nuniform mediump float u_pixelRatio;\nuniform sampler2D u_noiseTexture;\nuniform vec4 u_colorBack;\nuniform vec4 u_colors[4];\nuniform float u_colorsCount;\nuniform float u_shape;\nuniform float u_scale;\nuniform float u_rotation;\nuniform float u_offsetX;\nuniform float u_offsetY;\nuniform float u_originX;\nuniform float u_originY;\nuniform float u_worldWidth;\nuniform float u_worldHeight;\nuniform float u_fit;\n\nin vec2 v_objectUV;\nin vec2 v_patternUV;\nin vec2 v_objectBoxSize;\nin vec2 v_patternBoxSize;\nin vec2 v_responsiveUV;\nin vec2 v_responsiveBoxGivenSize;\nin vec2 v_imageUV;\nout vec4 fragColor;\n\n// helpers: snoise, fbmR, rotate, hash, etc.\n...\n```\n\nBut we need to include helper functions. We can use the same helper strings from `shader-mount.js` (`snoise`, `rotate`, `hash11`, `randomR`, `fbmR` from AuthBackground). For liquid metal, fbm noise is useful. We can include `snoise` and `fbmR`.\n\nLet's write a simpler helper set:\n- `#define PI 3.14159...`\n- `vec2 rotate(vec2 uv, float th)`\n- `float hash11(float p)`\n- `float hash21(vec2 p)`\n- `float randomR(vec2 p)` using noise texture\n- `float valueNoiseR(vec2 st)`\n- `vec4 fbmR(...)`\n- `float snoise(vec2 v)` (simplex)\n\nWe can copy these from the existing files. But simpler: we can include the same combined helper block from the original AuthBackground fragment (we have it in `~/concept-shader/index.html`). We can extract from there. Or write minimal helpers.\n\nLet's write minimal but sufficient helpers for liquid metal:\n\n```\n#define PI 3.14159265359\n\nfloat hash(vec2 p) {\n return fract(sin(dot(p, vec2(127.1, 311.7))) * 43758.5453);\n}\n\nfloat noise(vec2 p) {\n vec2 i = floor(p);\n vec2 f = fract(p);\n f = f*f*(3.0-2.0*f);\n float a = hash(i);\n float b = hash(i + vec2(1.0,0.0));\n float c = hash(i + vec2(0.0,1.0));\n float d = hash(i + vec2(1.0,1.0));\n return mix(mix(a,b,f.x), mix(c,d,f.x), f.y);\n}\n\nfloat fbm(vec2 p) {\n float v = 0.0;\n float a = 0.5;\n for (int i=0;i<5;i++) {\n v += a * noise(p);\n p *= 2.0;\n a *= 0.5;\n }\n return v;\n}\n\nvec2 rotate(vec2 uv, float th) {\n return mat2(cos(th), sin(th), -sin(th), cos(th)) * uv;\n}\n```\n\nThis avoids needing the noise texture. But the original shader requires `u_noiseTexture` because `randomR` uses it. If we don't use `u_noiseTexture`, we can still declare the uniform (WebGL will optimize it out if unused, but the vertex shader passes `v_imageUV` etc. We can keep `u_noiseTexture` uniform but not use it). However, the JS sets `u_noiseTexture` to 0 and creates the texture, which is fine.\n\nFor liquid metal, our own `fbm` with `noise` hash function works.\n\nNow design the modes:\n\n**Mode 1: Flow**\n```\nvec2 uv = v_objectUV * 1.5;\nfloat t = u_time * 0.2;\nfloat n = fbm(uv * 1.5 + t * 0.3);\nvec2 d = vec2(cos(uv.y*2.0 + t + n*2.0), sin(uv.x*2.0 - t + n*2.0));\nuv += d * 0.2;\nfloat p = sin(uv.x*3.0 + t) * cos(uv.y*3.0 - t*0.7);\np += 0.4 * sin(uv.x*7.0 - t*1.5);\np = p*0.5+0.5;\nfloat ridge = 1.0 - abs(sin(p * 8.0 - t*2.0));\nridge = pow(ridge, 5.0);\nfloat shine = pow(ridge, 12.0);\n```\n\n**Mode 2: Ripples**\n```\nvec2 uv = v_objectUV * 1.2;\nfloat t = u_time * 0.25;\nfloat d = length(uv * 0.7);\nfloat ripples = sin(d*12.0 - t*3.0) * 0.5 + 0.5;\nfloat n = fbm(uv*2.0 - t*0.2);\nfloat p = mix(ripples, n, 0.3);\nfloat ridge = pow(1.0 - abs(sin(p*10.0 - t*2.0)), 4.0);\n```\n\n**Mode 3: Chrome Waves**\n```\nvec2 uv = v_objectUV * 1.5;\nfloat t = u_time * 0.2;\nuv = rotate(uv, 0.3);\nfloat p = sin(uv.x*5.0 + uv.y*3.0 + t + fbm(uv*2.0+t*0.1)*1.5);\np = p*0.5+0.5;\nfloat ridge = pow(1.0 - abs(sin(p*12.0 + t*2.0)), 3.0);\n```\n\n**Mode 4: Blobs**\n```\nvec2 uv = v_objectUV * 1.5;\nfloat t = u_time * 0.2;\nfloat shape = 0.0;\nfor (int i=0; i<5; i++) {\n float fi = float(i);\n vec2 traj = 0.4*vec2(sin(t*0.7+fi), cos(t*0.5+fi*1.3));\n shape += 0.2 / (length(uv - traj) + 0.3);\n}\nfloat p = clamp(shape - 0.5, 0.0, 1.0);\nfloat ridge = pow(p, 3.0);\n```\n\nThen color mixing:\n```\nvec4 dark = u_colors[0];\nvec4 mid = u_colors[1];\nvec4 light = u_colors[2];\nvec4 spec = u_colors[3];\nfloat mix1 = smoothstep(0.2, 0.5, p);\nvec4 col = mix(dark, mid, mix1);\ncol = mix(col, light, ridge);\ncol = mix(col, spec, shine);\ncol.rgb *= col.a;\nvec3 final = col.rgb + u_colorBack.rgb * u_colorBack.a * (1.0 - col.a);\nfloat alpha = col.a + u_colorBack.a * (1.0 - col.a);\nfragColor = vec4(final, alpha);\n```\n\nBut `u_colorsCount` maybe 4. We'll pass 4 colors. Palettes:\n- Mercury: back #0b0c10, colors [#1f2833, #66fcf1, #c5f6fa, #ffffff] (teal? Not metal). Better: [#1a1a1a, #6b6b6b, #c4c4c4, #ffffff] (grayscale chrome).\n- Gold: back #1a1200, colors [#4a3b00, #b8860b, #ffd700, #fff8dc]\n- Rose Gold: back #1a0a0a, colors [#4a1c1c, #b76e79, #f7c4c4, #ffffff]\n- Cyber: back #050014, colors [#1a0b2e, #6d28d9, #22d3ee, #ffffff]\n\nLet's create the site. Since we need the vertex shader, we can copy from `~/concept-shader/index.html` and replace the fragment shader with our liquid metal one. Also update UI labels. We can create a new file `~/liquid-metal-site/index.html`.\n\nApproach: Use Python to read the existing `~/animated-site/index.html`, extract the vertex source and the HTML/JS UI, then replace the fragment source with our new one. Or just build from `~/concept-shader/index.html` as base and add UI, since `~/animated-site` has UI. Simpler: copy `~/animated-site/index.html` to `~/liquid-metal-site/index.html`, then replace the fragment shader section. The fragment shader starts after `const fragmentSource = \\`` and ends before `\\`;`? Actually in the file, `const fragmentSource = \\` ... \\`;` with backticks. The content includes backticks? GLSL doesn't have backticks. So we can find `const fragmentSource = \\`` and the matching closing backtick before `;`. But the file also has `const vertexSource = \\` before. We can split.\n\nAlternatively, build the file from scratch using the vertex shader from `~/concept-shader/index.html` and our new fragment, plus UI. Since the file is large, but we can write a Python script that reads the `animated-site/index.html` and uses regex to replace the fragment shader string. The fragment shader is between `const fragmentSource = \\`` and `\\`;` (the backtick before `;` on a line).

Then use regex to replace in `animated-site/index.html` and write to `liquid-metal-site/index.html`. We also need update UI labels: title, headings, shape names, palettes.\n\nLet's create the new fragment shader. Need include helpers. We'll write self-contained helpers using `noise` and `fbm`. We need to define them. The vertex shader outputs `v_objectUV`, `v_patternUV`, etc. We'll use `v_objectUV` as main coordinates.\n\nLet's design the fragment shader code. Important: it must compile in WebGL2 `#version 300 es`. Use `out vec4 fragColor;` and `in` for varyings. We'll include `in` for all varyings.\n\nThe original fragment shader from animated site has `in` declarations at top.

WebGL2 requires `for` loop with constant int. `for (int i=0; i<5; i++)` is fine. `u_colors[4]` uniform size 4. The JS passes 4 colors. Good.\n\nOne issue: `u_colors[4]` uses `u_colors` uniform location; `gl.uniform4fv` sets 4 vec4s. Good. We need `u_colorsCount` set to 4.\n\nThe vertex shader from before uses `u_noiseTexture` and `u_noiseTextureAspectRatio`? Actually vertex shader doesn't use `u_noiseTexture`. The original fragment used `u_noiseTexture`. Our new fragment doesn't use it, but the uniform is still declared in JS and bound to texture unit 0. WebGL will optimize out unused uniforms, but `gl.getUniformLocation` may return `null` for `u_noiseTexture` if not active. In our JS, we have `u_noiseTexture` in the list and `gl.uniform1i(u.u_noiseTexture, 0)`. If `u.u_noiseTexture` is `null`, `gl.uniform1i` throws? Actually `uniform1i` with a null location silently does nothing in WebGL? It may generate `INVALID_VALUE`? Let's check: In WebGL, if location is null, `uniform*` silently does nothing (no error). Actually `uniform1i(null, 0)` does nothing. So fine. But we don't need to create texture. However, creating it is harmless.\n\nAlso `u_noise`, `u_softness`, `u_intensity`, `u_softness` from original are not used in liquid shader. The JS still sets them. They will be null or optimized out, `uniform1f` null does nothing. Fine. But we might want to remove them from UI and JS to avoid confusion. Since we're replacing whole file, we can strip those uniforms and UI. But to keep \"same thing\", we can keep speed slider and maybe use `u_noise` or `u_intensity`? Let's repurpose `u_intensity` to control highlight intensity. But simpler: keep `u_noise`/`u_intensity` unused, or remove. The UI currently has shape, palette, speed. For liquid metal, we can add an `intensity` or `roughness` slider? Not necessary.\n\nWe need update the JS for palettes and shape names. Let's copy `animated-site/index.html` and modify.\n\nLet's write Python script that:\n1. Reads `animated-site/index.html`.\n2. Extracts vertex source (between `const vertexSource = \\`` and `\\`;`).\n3. Keeps HTML/JS up to fragment source and after fragment source.\n4. Replaces fragment source with new.\n5. Updates title, headings, shape buttons, palettes, default shape.\n6. Writes to `liquid-metal-site/index.html`.\n\nBut we can just do string replacements on the copied file. Use regex for fragment source replacement. Then string replace UI text and JS shape/palette definitions. Let's do.\n\nNeed be careful with the regex for fragment source. The pattern `const fragmentSource = \\`([\\s\\S]*?)\\`;` should match from `const fragmentSource = \\`` to the next `\\`;`. But the file contains backticks only for template literal start/end. In the HTML/JS, there are no other backticks. So regex safe.\n\nLet's run Python.","created_at":"2026-07-15T02:04:16.571768Z","finish_reason":"tool_calls","metrics":{"ttft_ms":2007,"total_time_ms":10103,"input_tokens":258,"output_tokens":5029,"cache_read_tokens":145664,"cache_creation_tokens":null,"tpot_ms":1.6098627957844502,"tokens_per_sec":621.1709486166009}},{"message_id":"f255d216-cb32-4e9b-95a2-3c9e41db8776","node_id":782,"role":"tool","content":"Output from command in shell 1fd9d2:\nWrote /Users/root1/liquid-metal-site/index.html size 17762\n\n\nExit code: 0","created_at":"2026-07-15T02:04:16.656619Z","finish_reason":null,"metrics":null},{"message_id":"cd09b4d3-7d3b-4975-a267-fa5de024b5b5","node_id":783,"role":"assistant","content":"","tool_calls":[{"id":"functions.exec:159","name":"exec","arguments":{"command":"python3 -m http.server 8082 --directory /Users/root1/liquid-metal-site > /tmp/liquid_server.log 2>&1","run_in_background":true,"timeout":10000}}],"thinking":"Now serve and verify.

The original had `const colors = ['#17376e','#2f5391','#abb7c5','#f5f1e6'].map(hexToVec4); const colorBack = hexToVec4('#091a33');`. We need update those to mercury palette. We only replaced the `palettes` object, but the initial colors are still ocean. The palette buttons call `setPalette` which uses `palettes`. So on load, the background is ocean, not mercury. The active button says Mercury but colors are ocean. Need fix.\n\nLet's update the initial `colors` and `colorBack` in the JS to mercury. Find and replace.","created_at":"2026-07-15T02:04:38.871062Z","finish_reason":"tool_calls","metrics":{"ttft_ms":1938,"total_time_ms":3129,"input_tokens":512,"output_tokens":422,"cache_read_tokens":151040,"cache_creation_tokens":null,"tpot_ms":2.822274881516588,"tokens_per_sec":354.32409739714524}},{"message_id":"b1dcd78b-8738-4d06-8619-5bd3d2f663e4","node_id":788,"role":"tool","content":"Found 2 match(es) for pattern 'const colors = \\[|const colorBack' in /Users/root1/liquid-metal-site/index.html:\n-- 2 matches in /Users/root1/liquid-metal-site/index.html\n 428|\n>429|const colors = ['#17376e','#2f5391','#abb7c5','#f5f1e6'].map(hexToVec4);\n>430|const colorBack = hexToVec4('#091a33');\n 431|","created_at":"2026-07-15T02:04:38.899576Z","finish_reason":null,"metrics":null},{"message_id":"57c15359-5b25-4b05-a131-91ad93a59635","node_id":789,"role":"assistant","content":"","tool_calls":[{"id":"functions.edit:162","name":"edit","arguments":{"file_path":"/Users/root1/liquid-metal-site/index.html","old_string":"const colors = ['#17376e','#2f5391','#abb7c5','#f5f1e6'].map(hexToVec4);\nconst colorBack = hexToVec4('#091a33');","new_string":"const colors = ['#1a1a1c','#6e6e72','#c8c8cc','#ffffff'].map(hexToVec4);\nconst colorBack = hexToVec4('#0a0a0b');"}}],"thinking":"Replace with mercury colors.

We need to improve the shader to look like real liquid metal. The current shader mixes colors based on pattern and ridges, but it lacks the key features of metal:\n\n- Metals have high contrast between dark shadowed areas and bright specular highlights.\n- The highlights should come from a light source/environment reflection, not just color mixing.\n- Use of Fresnel effect: edges are brighter (rim lighting) due to grazing angle reflections.\n- Anisotropic or environment-like reflections: a highlight map that looks like distorted reflections.\n- High-frequency specular noise (microfacet roughness) vs smooth color.\n- Use of `pow` for sharp highlights, but more importantly, compute a \"normal\" from the height field and reflect a light direction, or use environment map approximation.\n- Liquid metal also has chromatic aberration? Not necessary.\n\nThe \"correct way\" for metallic look in GLSL:\n1. Create a height field/perturbation from noise and patterns.\n2. Derive a normal from the gradient (partial derivatives) using `dFdx`, `dFdy` or analytical gradient. For each pixel, sample height at nearby UVs and compute `normal = normalize(vec3(-dh/dx, -dh/dy, 1.0))`.\n3. Define a view direction and light direction. For metal, use `reflect(-viewDir, normal)` to get reflection vector.\n4. Compute specular as `pow(max(dot(reflectDir, lightDir), 0.0), shininess)`. For metal, environment reflection can be approximated by a dot product with a fixed \"light\" direction plus noise.\n5. Fresnel: `F0 + (1.0 - F0) * pow(1.0 - max(dot(normal, viewDir), 0.0), 5.0)`. Metals have high F0 (0.5-1.0). Use it to modulate diffuse vs specular and rim brightness.\n6. Use a \"environment\" or \"reflection map\" approximated by a high-contrast procedural function of the reflection vector, e.g., `sin(reflectDir.x*10)`, `fbm(reflectDir.xy*2)`, etc.\n7. Color: metals have colored specular (gold, copper) but the base is dark. The diffuse term should be very dark; the metal color appears in the specular.\n\nWe need rewrite the fragment shader with a proper metallic BRDF-ish approximation. Since it's 2D surface (not 3D object), we can treat the surface as a height field and compute normals from derivatives. The view direction is roughly `(0,0,1)` (looking straight at the screen) but for perspective we can use vector from pixel to center? For fullscreen 2D, view dir can be `normalize(vec3(uv * 0.5, 1.0))` or `vec3(0,0,1)`. For a more 3D liquid effect, viewDir varying across screen: `vec3(uv*0.3, 1.0)`. Fresnel edges will be brighter.\n\nLiquid metal often uses \"matcap\" or \"environment reflection\" based on the normal. We can create a procedural environment:\n- A few bright horizontal/vertical bands or a checker/noise in the reflection direction.\n- Use `reflect(ray, normal)` where ray is `vec3(uv*0.5, 1.0)` or `vec3(0,0,1)`.\n- The reflection vector's xy gives UVs into an environment; use a high-contrast `fbm` or sine pattern to simulate reflected lights.\n\nKey: high contrast, sharp specular, dark base, rim light. Use HDR-like output by allowing values >1 and then tone map or clamp.\n\nLet's design the new metallic shader:\n\n```\n// Compute height field h at uv\nfloat getHeight(vec2 uv) {\n float h = 0.0;\n // combine modes similar to before\n if (mode == flow) ...\n else if (ripples) ...\n else if (chrome) ...\n else (blobs)\n return h;\n}\n\n// in main:\nvec2 uv = v_objectUV; // range roughly -0.5 to 0.5? Actually v_objectUV can be larger.\nuv = rotate(uv, rot); uv /= scale; uv += offset;\n\nfloat h = getHeight(uv);\n\n// Compute normal from gradient using dFdx/dFdy of uv? We can analytically perturb normal.\n// Simpler: sample height at neighbors using small offset.\nvec2 eps = vec2(0.005, 0.0);\nfloat hx = getHeight(uv + eps.xy) - h;\nfloat hy = getHeight(uv + eps.yx) - h;\nvec3 normal = normalize(vec3(-hx, -hy, 0.02)); // small z for stronger normal effect\n\n// View direction\nvec3 viewDir = normalize(vec3(uv * 0.4, 1.0)); // slight perspective\nvec3 reflectDir = reflect(-viewDir, normal);\n\n// Light / environment\nvec3 lightDir = normalize(vec3(cos(u_time*0.2), sin(u_time*0.2), 0.8)); // moving light\nfloat spec = pow(max(dot(reflectDir, lightDir), 0.0), 64.0);\n\n// Environment reflection from reflection vector\nfloat env = fbm(reflectDir.xy * 2.0 + u_time*0.1);\nenv = pow(env, 3.0); // high contrast\n// add bright strips\nfloat strip = pow(1.0 - abs(sin(reflectDir.x * 8.0)), 20.0);\nenv += strip * 0.5;\n\n// Fresnel\nfloat fresnel = 0.02 + 0.98 * pow(1.0 - max(dot(normal, viewDir), 0.0), 3.0);\n\n// Metal color (from palette)\nvec3 metalColor = u_colors[1].rgb; // mid metal\nvec3 specColor = u_colors[2].rgb; // highlight\nvec3 specWhite = u_colors[3].rgb; // white spec\n\nvec3 color = u_colorBack.rgb * 0.2; // very dark ambient\ncolor += metalColor * 0.05; // base metal tint\ncolor += specColor * env * 0.8;\ncolor += specWhite * spec * fresnel * 2.0;\ncolor += metalColor * fresnel * 0.3; // rim tint\n\nfragColor = vec4(color, 1.0);\n```\n\nBut this is simplistic. Better to compute a \"metallic\" material:\n- `diffuse` = baseColor * max(dot(normal, lightDir), 0.0) * (1.0 - metalness)\n- `specular` = F0 + (1.0 - F0) * fresnel? For metal, specular color = baseColor, and diffuse ~0.\n- Use Cook-Torrance-like: `D = pow(max(dot(normal, halfway),0.0), roughness)`? But we can use Blinn-Phong: `spec = pow(max(dot(normal, normalize(viewDir+lightDir)),0.0), shininess)`.\n\nThe key visual cue for metal is that the color of the highlight is the metal's color, not white (unless it's chrome/silver). For gold, highlights are gold; for silver, white.\n\nAlso, liquid metal has strong environment reflections. A procedural environment map can be made from `reflectDir` with sharp bright features.\n\nLet's think of a robust approach:\n\n1. **Height field** `h(uv)`:\n - For flow: use fbm + sine waves, output 0..1.\n - For ripples: rings + noise.\n - For chrome: diagonal waves.\n - For blobs: metaballs.\n2. **Normal** from height gradient:\n - Use analytical derivatives? `dFdx(h)` and `dFdy(h)` in fragment shader give screen-space derivatives. We can compute `vec3 normal = normalize(vec3(-dFdx(h), -dFdy(h), 0.01))`. But `dFdx` in GLSL gives derivative in screen space; to get in UV space, we can use `dFdx(uv)` and `dFdy(uv)`. More robust: `vec2 grad = vec2(dFdx(h), dFdy(h));` then transform by screen? Actually to get tangent-space normal from height field, we can use `dFdx` and `dFdy` of `h` directly as slopes in screen x/y, with a small z. That gives a normal. It will be noisy but that's fine for liquid metal. Use `float hx = dFdx(h); float hy = dFdy(h); vec3 normal = normalize(vec3(-hx, -hy, 0.02));`. This is correct for a height field in screen space.\n - But the magnitude of derivatives may be too small/large. The `h` function should produce strong height variations. We can scale `h` by an amplitude.\n3. **Reflection**:\n - `vec3 view = normalize(vec3(0.0, 0.0, 1.0));` or with slight perspective `vec3 view = normalize(vec3(uv*0.3, 1.0));`.\n - `vec3 reflect = reflect(-view, normal);`\n - The `reflect.z` will be near 1 when normal is flat; `xy` gives the reflected environment direction.\n4. **Procedural environment**:\n - Use `fbm` of `reflect.xy * scale + time*0.05` to get low-frequency reflections.\n - Add a few \"light sources\" as bright spots/directions: compute dot product with a few fixed light directions and pow.\n - For example: `float env = fbm(reflect.xy*2.0 + t*0.1);` then `env = pow(env, 2.0)` to increase contrast.\n - Add anisotropic streaks: `float streak = pow(max(sin(reflect.x*10.0 + t),0.0), 20.0);`\n - Add a \"window\" reflection: `float window = smoothstep(0.4,0.6, abs(fract(reflect.y*2.0)-0.5));`? Not.\n5. **Metal shading**:\n - For metals, `specular color = metal color`, diffuse ~0.\n - `float ndotl = max(dot(normal, lightDir), 0.0);`\n - `vec3 halfVec = normalize(view + lightDir);`\n - `float spec = pow(max(dot(normal, halfVec), 0.0), 128.0 * (1.0-roughness))`? High exponent for sharp highlights.\n - Use `fresnel` to boost edges.\n - `vec3 output = baseColor * ambient + metalColor * envReflection * fresnel + specColor * spec * fresnel;`\n6. **Liquid effect**: Animate height field with time; normal changes, causing reflections to flow. This is already done.\n\nLet's implement a proper metallic shader with these ideas. Need decide on palettes:\n- Mercury: base `#0a0a0b`, metal `#6e6e72`, highlight `#c8c8cc`, specular `#ffffff` (white/silver highlights).\n- Gold: base `#120f05`, metal `#a67c00`, highlight `#ffd700`, specular `#fff8dc`.\n- Rose: base `#140a0a`, metal `#b76e79`, highlight `#f7c4c4`, specular `#ffffff`.\n- Cyber: base `#050514`, metal `#5b21b6`, highlight `#06b6d4`, specular `#e0f2fe`.\n\nIn the shader, we can interpret `u_colors[0]` as base/diffuse, `u_colors[1]` as metal tint, `u_colors[2]` as reflection/highlight color, `u_colors[3]` as specular core. `u_colorBack` as ambient/background.\n\nThe fragment shader should be self-contained. Use `dFdx`/`dFdy` for normals. Need ensure `#extension GL_OES_standard_derivatives`? In WebGL2 `#version 300 es`, `dFdx`, `dFdy`, `fwidth` are built-in. Good.\n\nLet's design the height function:\n\n```\nfloat getHeight(vec2 uv, float t) {\n float h = 0.0;\n if (u_shape < 1.5) {\n // Flow: domain warped fbm + sine\n float n = fbm(uv*1.5 + t*0.3);\n uv += vec2(cos(uv.y*3.0 + t + n*2.0), sin(uv.x*3.0 - t + n*2.0)) * 0.15;\n h = sin(uv.x*4.0 + t) * cos(uv.y*4.0 - t*0.7);\n h += 0.3 * sin(uv.x*9.0 - t*1.5);\n h = h*0.5 + 0.5;\n } else if (u_shape < 2.5) {\n // Ripples\n float d = length(uv*0.7);\n h = sin(d*16.0 - t*4.0) * 0.5 + 0.5;\n h += 0.2 * fbm(uv*3.0 - t*0.2);\n h = clamp(h, 0.0, 1.0);\n } else if (u_shape < 3.5) {\n // Chrome waves\n uv = rotate(uv, 0.4);\n h = sin(uv.x*6.0 + uv.y*4.0 + t + fbm(uv*2.5 + t*0.1)*1.2);\n h += 0.3 * sin(uv.x*12.0 - uv.y*8.0 - t*2.0);\n h = h*0.5 + 0.5;\n } else {\n // Blobs\n float s = 0.0;\n for (int i=0; i<5; i++) {\n float fi = float(i);\n vec2 traj = 0.3 * vec2(sin(t*0.5 + fi*1.7), cos(t*0.35 + fi*1.3));\n s += 0.2 / (length(uv - traj) + 0.25);\n }\n h = clamp(s - 0.5, 0.0, 1.0);\n }\n return h;\n}\n```\n\nThen in main:\n```\nfloat t = u_time * 0.15;\nvec2 uv = v_objectUV;\nuv = rotate(uv, u_rotation * PI / 180.0);\nuv /= u_scale;\nuv += vec2(-u_offsetX, u_offsetY);\n\nfloat h = getHeight(uv, t);\n// normal from derivatives\nvec2 dh = vec2(dFdx(h), dFdy(h));\n// scale derivatives to control bump strength\ndh *= 30.0; // tune\nvec3 normal = normalize(vec3(-dh, 0.02));\n\n// view direction\nvec3 viewDir = normalize(vec3(uv * 0.3, 1.0));\n// or fixed viewDir = vec3(0,0,1)\nvec3 reflectDir = reflect(-viewDir, normal);\n\n// lights\nvec3 lightDir = normalize(vec3(cos(t*0.5), sin(t*0.5), 0.7)); // moving light\nvec3 halfVec = normalize(viewDir + lightDir);\nfloat ndotl = max(dot(normal, lightDir), 0.0);\nfloat spec = pow(max(dot(normal, halfVec), 0.0), 96.0);\n// specular tint\nvec3 specColor = u_colors[3].rgb * spec;\n\n// environment reflection from reflectDir\nfloat env = fbm(reflectDir.xy * 2.5 + t * 0.1);\nenv = pow(env, 3.0); // high contrast\n// bright streaks in reflection\nfloat streak = pow(1.0 - abs(sin(reflectDir.x * 6.0 + t)), 12.0);\nenv += streak * 0.3;\nenv = clamp(env, 0.0, 1.0);\n\n// fresnel\nfloat fresnel = 0.04 + 0.96 * pow(1.0 - max(dot(normal, viewDir), 0.0), 2.5);\n\n// metal composition\nvec3 base = u_colorBack.rgb * 0.15; // ambient\nvec3 metal = u_colors[1].rgb * env * 0.8; // reflection color\nvec3 highlight = u_colors[2].rgb * env * 0.5; // secondary reflection\nvec3 core = u_colors[3].rgb * spec * fresnel * 2.0; // bright specular core\n\nvec3 color = base + metal + highlight + core;\ncolor += u_colors[1].rgb * fresnel * 0.2; // rim metal tint\n\nfragColor = vec4(color, 1.0);\n```\n\nBut the issue is `dFdx(h)` depends on `h` changing across screen. If `h` is too smooth, normal will be flat. The height function must have high enough frequency. The derivatives might be too small; we multiply by `30.0`. But the absolute scale of `uv` in screen space: `v_objectUV` covers the screen with values maybe [-0.5,0.5] * worldScale. `dFdx(uv)` is tiny? Actually `dFdx(h)` is derivative of `h` with respect to screen x. If `h` changes over many pixels, derivative is small. Multiplying by 30 may be too much or too little. We can tune.\n\nAlso, the `normal` computed from screen-space derivatives may cause the reflection to be heavily distorted but it can look cool. However, for liquid metal, normals should be derived from the height field in UV space, not screen space, because the height field is defined in UV space. Using `dFdx(h)` in screen space is okay if the UV mapping is roughly uniform, but if the canvas is resized, the bump scale changes with resolution. Better to compute gradient in UV space using `dFdx(uv)` and `dFdy(uv)`:\n\n```\nvec2 uvx = dFdx(uv);\nvec2 uvy = dFdy(uv);\n// approximate dh/duv by sampling? Actually h is function of uv, but dFdx(h) = dot(grad_h, dFdx(uv)).\n// We can compute grad_h analytically? Hard. Instead sample h at uv + small offset.\nfloat h1 = getHeight(uv + vec2(0.001,0.0), t);\nfloat h2 = getHeight(uv + vec2(0.0,0.001), t);\nvec2 grad = (vec2(h1,h2) - h) / 0.001;\nvec3 normal = normalize(vec3(-grad.x, -grad.y, 0.5));\n```\n\nSampling `getHeight` twice per pixel adds cost but fine. The `getHeight` function can be evaluated 3 times per pixel (center + x + y). This gives a stable normal independent of screen resolution. But the small offset (0.001 in uv space) might be too small relative to fbm high frequencies; could produce noisy normals. We can use `0.002` or `0.005`. For liquid metal, fine.\n\nBut `getHeight` is expensive with fbm loops. Calling it 3 times per pixel is okay for 720p. For 4K maybe slow. We can lower fbm octaves or use `dFdx` screen-space. For quality, use screen-space derivative trick: `vec2 dh = vec2(dFdx(h), dFdy(h));` and then transform to uv space by dividing by `dFdx(uv)` and `dFdy(uv)`? Actually `dFdx(h) = dot(grad_h, dFdx(uv))`. To recover `grad_h`, we need solve 2 equations: `dFdx(h) = grad_h.x * dFdx(uv).x + grad_h.y * dFdx(uv).y`, `dFdy(h) = grad_h.x * dFdy(uv).x + grad_h.y * dFdy(uv).y`. This is a 2x2 linear system. But `dFdx(uv)` and `dFdy(uv)` are mostly along x and y (since uv maps to screen), so we can approximate `grad_h.x ≈ dFdx(h) / dFdx(uv.x)`, `grad_h.y ≈ dFdy(h) / dFdy(uv.y)`. If `uv.x` increases left-to-right, `dFdx(uv.x)` is positive. This gives uv-space gradient. Then normal = normalize(vec3(-grad_h.x * bumpScale, -grad_h.y * bumpScale, 1.0)). This is efficient and resolution independent. Let's do that.\n\n```\nvec2 duvdx = dFdx(uv);\nvec2 duvdy = dFdy(uv);\nfloat hx = dFdx(h);\nfloat hy = dFdy(h);\nfloat gx = hx / (abs(duvdx.x) + 1e-5);\nfloat gy = hy / (abs(duvdy.y) + 1e-5);\nvec3 normal = normalize(vec3(-gx * 0.03, -gy * 0.03, 1.0));\n```\n\nBut `dFdx(uv)` and `dFdy(uv)` may be zero if `uv` is constant across screen? No, `v_objectUV` varies across screen. However, for a perspective-correct interpolation, `dFdx(uv.x)` may not be constant. The sign may be negative if `uv` maps flipped. We use `abs`. Also `duvdx.y` may not be exactly 0 but small; we ignore. This is approximate but works.\n\nAlternatively, use `fwidth` and simpler normal: `vec2 grad = vec2(dFdx(h), dFdy(h)) * 50.0; vec3 normal = normalize(vec3(-grad, 1.0));` and accept screen-space derivative. The bump strength will vary with resolution. For a given viewport it's fine. But to be \"correct\", we want resolution independent. Yet for a demo, screen-space is acceptable. The user asked \"figure out the correct way\". So we should derive normals from the height field properly. Let's use the analytical gradient via sampling. It is more correct.\n\nBut analytical gradient via sampling has the problem that the `uv` varies non-linearly due to `rotate`, `scale`, `offset`, but those are linear transformations, so `getHeight` is evaluated in transformed uv. Sampling with a small offset in transformed uv gives correct gradient in that space. The normal is in the transformed uv space; we then need transform to view space. Since the canvas is a flat plane, the tangent space is aligned with screen. If `uv` is proportional to screen coordinates, normal is fine. The original `v_objectUV` is computed from `gl_Position` (screen) and `u_resolution`, so it's proportional to screen position. Good.\n\nLet's implement sampling-based normal. Use a small `e = 0.002`. Compute `h`, `hx = getHeight(uv + vec2(e,0), t)`, `hy = getHeight(uv + vec2(0,e), t)`. Then `grad = (vec2(hx, hy) - h) / e`. `normal = normalize(vec3(-grad.x * bump, -grad.y * bump, 1.0))`. `bump` controls strength; maybe 0.01-0.03. For high-frequency height, `grad` may be large; use `0.01`. Actually the `grad` values can be huge (height changes by 1 over 0.001 -> grad 1000). So `bump` should be very small, like `0.0005`? Let's think: `normal = normalize(vec3(-grad*bump, 1))`. If `grad` ~ 100, `bump` = 0.01 gives z=1, xy=1, normal tilt 45 degrees. That's strong. If grad ~ 10, bump=0.01 gives xy=0.1, subtle. We can tune. We can also scale height output to [-1,1] or [0,1] and reduce amplitude. In `getHeight`, we can multiply by `0.3` to keep slopes moderate. Then `bump` can be 0.02.\n\nWe can also avoid sampling 3 times by computing the gradient analytically? Not feasible for fbm. But we can reduce `getHeight` cost by using lower octaves (3 instead of 5) and simpler noise. For liquid metal, 3 octaves may be enough.\n\nLet's refine the height function to be more metallic:\n\n- Use `fbm` with 4 octaves.\n- Multiply height by amplitude `0.4`.\n- Add moving sine waves.\n\nNow the metal shading. Key: use `reflect` and environment.\n\nEnvironment reflection: We can define a procedural environment map:\n```\nfloat env(vec3 r) {\n // moving bands\n float e = sin(r.x*8.0 + u_time*0.2) * sin(r.y*8.0 - u_time*0.15);\n e = e*0.5+0.5;\n e = pow(e, 4.0);\n // bright diagonal streak\n float streak = pow(1.0 - abs(sin(r.x*3.0 + r.y*3.0 + u_time*0.3)), 8.0);\n e += streak;\n // noise\n e += fbm(r.xy*3.0 + u_time*0.1) * 0.3;\n return clamp(e,0.0,1.0);\n}\n```\n\nBut `r` is reflection vector `vec3`; use `r.xy` for environment UV. The `r.z` indicates how \"forward\" the reflection is; we can use it to fade or not.\n\nLights:\n- `lightDir = normalize(vec3(0.5, 0.8, 0.6))` or moving.\n- `spec = pow(max(dot(reflect(-viewDir, normal), lightDir), 0.0), 64.0)` (Phong reflection).\n- Also `blinn = pow(max(dot(normal, normalize(viewDir+lightDir)),0.0), 128.0)`.\n\nFor metal, the highlight color should be the specular color `u_colors[3]`. The environment reflection color should be `u_colors[2]`. The base `u_colors[1]`. Ambient/dark `u_colorBack`.\n\nLet's also add a subtle iridescent Fresnel? Not needed.\n\nWe can also add chromatic separation: compute reflection slightly differently for R, G, B to get color fringing. That could look more metallic/liquid. For example:\n```\nfloat fresnel = ...;\nvec3 reflect = reflect(-view, normal);\nfloat envR = env(reflect + vec3(fresnel*0.02,0,0));\n...\n```\nOr more simply, shift `normal` per channel. But maybe too much.\n\nLet's implement a solid physically-ish shader. Also consider that the `u_colors` array size is 4. We can use:\n- `u_colors[0]` not used (or as deep shadow)\n- `u_colors[1]` base metal tint\n- `u_colors[2]` reflection/highlight color\n- `u_colors[3]` specular core color\n\nAnd `u_colorBack` as ambient/background.\n\nPalettes:\n- Mercury: back `#050505`, colors `[#0a0a0a, #555555, #bbbbbb, #ffffff]`\n- Gold: back `#0f0a00`, colors `[#2a1f00, #8a6d00, #e6c200, #fff8dc]`\n- Rose: back `#0f0505`, colors `[#2e1515, #a85e6a, #f7c4c4, #ffffff]`\n- Cyber: back `#03010a`, colors `[#120a2a, #4c1d95, #22d3ee, #e0f2fe]`\n\nNow implement in `liquid-metal-site/index.html`. We can either edit the existing file or create a new version. The user says \"make the same thing but with a more liquid metal vibe\". So update the existing `~/liquid-metal-site/index.html` with the improved shader. Keep the UI. Let's rewrite the fragment shader in the file.\n\nNeed extract the existing file and replace fragment shader. The fragment source is between `const fragmentSource = \\`` and `\\`;`. We can use Python regex again. Also update palettes maybe. The initial colors should be mercury. The shape buttons same (Flow, Ripples, Chrome, Blobs). Speed slider same. We can also add an `intensity` or `roughness` slider? Maybe add a `bump` slider for normal strength? Not necessary; we can tune.\n\nLet's write the new fragment shader and replace. Also update the `colors`/`colorBack` initial values to the new mercury palette.\n\nLet's write a Python script to replace fragment and update colors.","created_at":"2026-07-15T02:05:38.483039Z","finish_reason":"tool_calls","metrics":{"ttft_ms":1958,"total_time_ms":24802,"input_tokens":560,"output_tokens":8930,"cache_read_tokens":152832,"cache_creation_tokens":null,"tpot_ms":2.558118701007839,"tokens_per_sec":390.9122745578708}},{"message_id":"bc908df1-a589-4cd7-8178-f25cc7c8fe21","node_id":800,"role":"tool","content":"Output from command in shell 2048e6:\nWrote /Users/root1/liquid-metal-site/index.html size 19147\n\n\nExit code: 0","created_at":"2026-07-15T02:05:38.530238Z","finish_reason":null,"metrics":null},{"message_id":"9fa384fd-4368-4780-884d-a6bd6bfc90d3","node_id":802,"role":"assistant","content":"","tool_calls":[{"id":"functions.exec:167","name":"exec","arguments":{"command":"for shape in 1 2 3 4; do\n \"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome\" --no-sandbox --headless=new --enable-unsafe-swiftshader --use-angle=swiftshader --screenshot=\"/tmp/liquid2_${shape}.png\" --window-size=1280,720 --run-all-compositor-stages-before-draw --virtual-time-budget=4000 \"http://localhost:8082/?shape=${shape}\" > \"/tmp/chrome_liquid2_${shape}.log\" 2>&1\n echo \"shape $shape done\"\ndone\npython3 - << 'EOF'\nfrom PIL import Image\nfor i in range(1,5):\n im = Image.open(f'/tmp/liquid2_{i}.png').convert('RGB')\n px = list(im.getdata())\navg = [sum(c[i] for c in px)//len(px) for i in range(3)]\n mx = max(max(c) for c in px)\n mn = min(min(c) for c in px)\n print(f'liquid2 {i}: avg {avg}, min {mn}, max {mx}')\nEOF","timeout":120000}}],"thinking":"Now capture screenshots.

We can improve further by:\n- Adding a clearcoat/anisotropic highlight.\n- Using environment map with more distinct bright features.\n- Adding subtle color shifts per channel for iridescence.\n- Using `ACES` tone mapping or exposure to make bright highlights pop.\n- Increase contrast: maybe the average is too gray because the environment reflection is not high-contrast enough. We can make `environment` more binary (dark + bright spots). Real metal reflects the environment; if the environment is low-contrast gray, metal looks gray. We should make the environment map have distinct lights.\n\nLet's improve the environment function to produce high-contrast reflections: bright bands and dark areas, like a studio with bright rectangular lights. For example:\n\n```\nfloat environment(vec3 r, float t) {\n // Base dark reflection\n float e = 0.0;\n // Moving bright rectangular bands\n float band1 = smoothstep(0.45, 0.55, sin(r.x * 4.0 + t * 0.3));\n float band2 = smoothstep(0.45, 0.55, sin(r.y * 5.0 - t * 0.2));\n e += band1 * 0.8;\n e += band2 * 0.6;\n // Sharp circular highlights\n float spot = 1.0 - length(fract(r.xy * 2.0 + t * 0.1) - 0.5) * 2.0;\n e += pow(max(spot, 0.0), 8.0) * 0.5;\n // Noise grain\n e += fbm(r.xy * 4.0 + t * 0.15) * 0.2;\n return clamp(e, 0.0, 1.0);\n}\n```\n\nThis will produce bright distinct reflections. Also, the specular highlight from light should be very sharp. We can also add a second rim light.\n\nBut the current version already has `environment` with `pow` and streak. Maybe it's okay. However, the average [62,62,64] suggests it's mostly mid-gray. That may be because the `env` reflection is not strong enough or too spread out. We can increase the contrast by applying a contrast curve to the final color: `color = (color - 0.5) * 1.5 + 0.5`? But we already `pow(color, 0.85)` which brightens midtones. We can also add `color = pow(color, vec3(0.7))` to push darks up? That makes more gray. Instead, we want darks darker and brights brighter: `color = pow(color, vec3(0.8))` compresses? Actually `pow(x, 0.8)` for x<1 increases; for dark values, increases, reducing contrast. We want a sigmoid or contrast: `color = (color - 0.5) * contrast + 0.5`. Or use `mix(color, color*color, ...)`. For metal, we want high contrast: `color = smoothstep(0.0, 1.0, color)`? That maps 0.5 to 0.5, but stretches extremes. Or `color = pow(color, vec3(1.5))` darkens midtones, increasing contrast? For x<1, pow(x, 1.5) < x, so midtones get darker, increasing contrast. That may help.\n\nLet's adjust: remove `pow(color, 0.85)`, instead use `color = pow(color, vec3(1.4))` to darken midtones and make highlights pop more relative. But if color is small, it becomes smaller. Ambient 0.12 becomes 0.05, good. Reflections at 0.8 become 0.74. Highlights at 2.5 become pow(2.5,1.4)=3.8 (clamp to 1). So highlights blow out to white. That looks metallic.\n\nAlso `environment` can be more high-contrast: `env = pow(env, 2.0)` and multiply by 1.5. But if env is 0.5, pow=0.25, darkening reflection. Maybe use `env = smoothstep(0.3, 0.7, env)` to make reflections binary. Or `env = pow(env, 0.5)` to brighten? For metal, reflections should be bright where environment is bright and dark elsewhere. The environment function should be high-contrast by design. Let's rewrite `environment` to have bright bands/spots.\n\nAlso add `specular` from a static bright light and a moving fill light, with high exponent. The `spec` is `pow(max(dot(normal, halfVec),0.0), 128.0)`. For very small highlights, exponent 256. But on a noisy surface, the highlight will sparkle. Good.\n\nMaybe the current version is already an improvement. But the user explicitly wants \"more metallic, figure out the correct way\". Let's further improve and explain the correct way.\n\nThe correct way for metal in real-time graphics:\n- Use physically-based material: metal has no diffuse, specular color = base color, Fresnel high.\n- Use a normal map from a height field.\n- Use environment mapping for reflections.\n- Use high-contrast lighting.\n\nLet's implement these properly. We can update the fragment shader again. Let's design a robust PBR-ish metal shader with:\n- `roughness` parameter (could be uniform or fixed). We can expose a `roughness` slider? The UI could have a roughness slider. But user asked \"same thing\", so maybe not. However, adding a roughness slider would help tune metallic look. Let's add a `roughness` uniform and a slider, since it's useful. But the existing JS doesn't have it. We can add.\n- `metalness` fixed at 1.0.\n- `F0` color = `u_colors[1].rgb`.\n- `diffuse` = `u_colorBack.rgb * 0.05`.\n- `specular` = Cook-Torrance D term: `D = alpha^2 / (PI * ( (NdotH)^2 * (alpha^2 - 1) + 1)^2 )`, where `alpha = roughness^2`. But simpler: `D = pow(NdotH, (1.0-roughness)*128.0 + 4.0)`. That's fine.\n- `F` = F0 + (1 - F0) * (1 - VdotH)^5 (Fresnel-Schlick).\n- `k = ((roughness+1)^2)/8` for geometry. Simplify geometry to `G = NdotV / (NdotV * (1-k) + k)`. Actually Blinn-Phong with Fresnel is okay.\n- Combine: `specular = D * F * G / (4 * NdotV * NdotL + 0.001)`.\n- Environment reflection: `envColor` * `F` (metals reflect environment colored by F0). Use a high-contrast procedural environment.\n- Add ambient occlusion from height? Not necessary.\n\nBut for a 2D shader, a simpler Blinn-Phong + environment map looks more controllable. Let's refine the environment to be high-contrast.\n\nLet's write final improved fragment:\n\n```\n#version 300 es\nprecision lowp float;\n\n... uniforms (same) ...\n\n#define PI 3.14159265359\n\n... noise helpers ...\n\nfloat environment(vec3 r, float t) {\n // Studio light bands\n float bandX = sin(r.x * 5.0 + t * 0.25) * 0.5 + 0.5;\n float bandY = sin(r.y * 6.0 - t * 0.18) * 0.5 + 0.5;\n float bands = max(bandX, bandY);\n bands = smoothstep(0.35, 0.65, bands);\n\n // Moving circular spotlights\n vec2 spotUV = fract(r.xy * 1.5 + vec2(t * 0.08, t * 0.06)) - 0.5;\n float spot = 1.0 - length(spotUV) * 2.0;\n spot = pow(max(spot, 0.0), 12.0);\n\n // Fine grain\n float grain = fbm(r.xy * 4.0 + t * 0.1);\n\n float env = bands * 0.7 + spot * 1.2 + grain * 0.15;\n return clamp(env, 0.0, 1.0);\n}\n\nfloat getHeight(...) { ... }\n\nvoid main() {\n float t = u_time * 0.15;\n vec2 uv = ...;\n\n // Normal\n float h = getHeight(uv, t);\n float e = 0.003;\n vec2 grad = (vec2(getHeight(uv+vec2(e,0),t), getHeight(uv+vec2(0,e),t)) - h) / e;\n vec3 normal = normalize(vec3(-grad*0.012, 1.0));\n\n // View / light\n vec3 viewDir = normalize(vec3(uv*0.35, 1.0));\n vec3 reflectDir = reflect(-viewDir, normal);\n vec3 lightDir = normalize(vec3(cos(t*0.4), sin(t*0.35), 0.85));\n vec3 halfVec = normalize(viewDir + lightDir);\n\n float NdotV = max(dot(normal, viewDir), 0.0);\n float NdotL = max(dot(normal, lightDir), 0.0);\n float NdotH = max(dot(normal, halfVec), 0.0);\n\n // Fresnel (Schlick) for metal\n vec4 metalCol = u_colors[1];\n vec4 specCol = u_colors[3];\n vec4 reflCol = u_colors[2];\n vec3 F0 = metalCol.rgb;\n vec3 F = F0 + (1.0 - F0) * pow(1.0 - NdotV, 5.0);\n\n // Blinn-Phong specular with metal color\n float roughness = 0.15;\n float shininess = (1.0 - roughness) * 256.0 + 8.0;\n float spec = pow(NdotH, shininess);\n\n // Environment reflection\n float env = environment(reflectDir, t);\n\n // Combine\n vec3 color = u_colorBack.rgb * 0.08; // ambient\n color += metalCol.rgb * 0.05; // base\n color += reflCol.rgb * env * F * 2.0; // environment reflection\n color += specCol.rgb * spec * NdotL * 3.0; // specular highlight\n\n // Contrast / tone\n color = pow(color, vec3(1.3)); // darken mids, blow highlights\n color = clamp(color, 0.0, 1.0);\n\n fragColor = vec4(color, 1.0);\n}\n```\n\nWait, `F = F0 + (1-F0)*(1-NdotV)^5`. For metal, F0 is the metal color (e.g., gold). At grazing angles, `F` approaches white. This is good. But `environment` multiplied by `F` means reflections are tinted by metal color. For silver, F0 ~ white. For gold, F0 gold. Good.\n\n`reflCol` maybe not needed if F handles color. But we can use `u_colors[2]` as the highlight/overbright color. Use `metalCol` for environment, `specCol` for spec.\n\nWe can simplify: `color += metalCol.rgb * env * 2.0 * F; color += specCol.rgb * spec * 3.0;`\n\nAlso, `pow(color, 1.3)` will darken ambient and mid reflections, making image overall darker but highlights pop. However, if `env` is 0.5, `color` contributions: ambient 0.08*0.02? Let's compute: base metal 0.05, env 0.5*metal*2*F ~ 0.5*0.7*2=0.7, spec maybe 1.0. Total ~1.75. pow(1.75,1.3)=2.25 clamp to 1. So highlights are clipped white. Mid values 0.4 -> 0.28. Good. Dark values 0.05 -> 0.02. Good contrast.\n\nBut we need avoid the whole image becoming too dark. `environment` should have bright spots. Let's make it more aggressive. Maybe add `bands` and `spot` as above. Also, `fbm` grain will be 0.5 average, adding midtones. To keep contrast, we can use `grain = fbm(...)`, then `grain = smoothstep(0.3,0.7,grain)` to make it binary. But `fbm` returns 0..1 with average 0.5. If we use `grain` as mid reflection, it gives gray. For liquid metal, we want reflections of bright lights, not gray ambient. So `environment` should have large dark areas and bright bands/spots. Use `bands` with `smoothstep` and `spot` with pow. Add `grain` multiplied by 0.1 to break up highlights. So environment is mostly dark with bright features. That will look like metal reflecting studio lights.\n\nLet's update the fragment. Also, maybe expose `roughness` as a uniform and add a slider in the UI. The user asked \"same thing\" but adding roughness helps. We can add `u_roughness` uniform and a slider. But if we don't, we can fix roughness to 0.15. Let's add a roughness slider for control; it's small change in UI and JS. Actually the user said \"its not metallic at all\" — giving them roughness control helps tune. But also the page becomes more complex. Let's add.\n\nUI: add a \"Roughness\" slider (0.0 to 1.0, step 0.01, value 0.15). Add `u_roughness` to uniforms and `gl.getUniformLocation`. In fragment, `uniform float u_roughness;`. In main, use it for shininess and maybe normal bump strength (rougher surfaces have softer normals). Add `bump = (1.0 - u_roughness) * 0.012 + 0.002`? Actually rougher metal has more micro-surface variation; normal bump should be higher. So `bump = u_roughness * 0.02 + 0.003`. And `shininess = (1.0 - u_roughness) * 256.0 + 4.0`.\n\nLet's implement. Need update HTML/JS. The fragment currently doesn't have `u_roughness` uniform. We'll add. The JS list of uniforms and bottom initial setting. Add slider in HTML.\n\nLet's do a comprehensive update with Python. Read the current file, replace fragment source with improved version, add roughness UI, update JS. We can use regex and string replacements. But it's getting complex. Let's write the file fresh with a Python script that builds it from `animated-site/index.html` or `liquid-metal-site/index.html`. Since we have the file, we can replace specific parts.\n\nMaybe easier: Write a new complete `index.html` file using Python with the improved shader, UI, and JS.

However, the user may want even more metallic. Let's consider if there are issues:\n- The environment is mostly dark, so the metal looks dark except for specular highlights. Real liquid metal has bright reflected environment. We need a brighter environment with distinct light sources. The `environment` function currently has `bands` and `spot` but maybe they are too small/dim. Let's compute `environment` values: `bands` = `smoothstep(0.35,0.65,max(bandX,bandY))`. For `r.x` from -1 to 1, `bandX` sinusoidal. `max(bandX,bandY)` high when either band high. `smoothstep` makes it 0 or 1 mostly. `bands*0.8` gives 0.8 in bright areas. `spot` is a small spotlight (pow 14) with 1.5 max. `grain` small. So environment can be up to ~2.3 but clipped to 1. That's good. But perhaps the `reflectDir` values are such that only a small portion hits bright spots, causing average dark.\n\nWe can improve by making the environment always have some brightness: add a constant ambient reflection (e.g., 0.1) plus bright features. Or use a spherical gradient: `env = max(dot(reflectDir, vec3(0,0,1)), 0.0)` as base? That would make facing reflections bright. But for liquid metal, we want the environment to look like a room with lights.\n\nMaybe the issue is `pow(color, 1.35)` darkens too much. With ambient 0.08 + base 0.05 + env up to 1*F*2.2 ~ 2.2, total ~2.3 -> pow(2.3,1.35)=2.9 clamp 1. So bright reflections become white. But if `env` is 0.1 (dark area), total 0.08+0.05+0.1*2.2*~0.5=0.08+0.05+0.11=0.24, pow(0.24,1.35)=0.13. So dark areas are very dark. That's high contrast. Good. But the user may want the metal to look shiny, not dark. They can adjust roughness or use a brighter palette? The `metalCol` is `#3a3a3c`, `reflCol` `#b0b0b6`. In dark environment, the metal looks dark. Maybe we should increase the `base metal` and `environment` contributions. Also `metalCol` for mercury is gray; in dark it looks black. We can use a slightly lighter base or increase ambient reflection.\n\nFor liquid metal, the base color in shadow should still look metallic, not black. Add a \"metal sheen\" term: `color += metalCol.rgb * 0.15;` instead of 0.05. Also `environment` can have a baseline of 0.15 (like ambient environment). And `pow(color,1.35)` maybe too aggressive; use `1.2` or use contrast curve that preserves midtones better. Let's adjust:\n- `color += metalCol.rgb * 0.12;`\n- `env = clamp(bands*0.8 + spot*1.5 + grain + 0.15, 0.0, 1.0);` add ambient 0.15.\n- `pow(color, vec3(1.2));` (less crush).\n- `reflCol` multiply by `2.5` to brighten reflections.\n- `spec` multiply by `4.0`.\n\nLet's test.

This is ambiguous. It could be a challenge: \"you can't do it, that's interesting\" meaning the task is hard and they are interested to see if I can. Or it could be a reaction to the metal shader not being good enough, implying I can't make it truly metallic. It could also be a vague prompt for me to do something even more impressive.\n\nGiven the context, they might be expressing doubt/skepticism and want me to prove I can. Or they are saying \"you can't do it\" as a statement and \"that's interesting\" as a reflection. We should ask what they want? But maybe they want me to push further and actually make it look like liquid metal, perhaps by using a real environment map, anisotropic reflections, better noise, or even raymarching a 3D liquid metal surface.\n\nThe previous shader is 2D. For truly convincing liquid metal, one could:\n- Use a precomputed HDR environment map (not procedural).\n- Use anisotropic highlights.\n- Add chromatic aberration / iridescence.\n- Use ray-marched 3D SDF liquid blobs with reflection/refraction.\n- Use a MatCap (material capture) texture for metal look.\n\nBut the user might be mocking that I can't achieve a true liquid metal look. We should respond honestly: the 2D procedural approach has limits; to get photorealistic liquid metal, you need environment maps / raytracing / 3D. Ask if they want me to try a more advanced technique, e.g., a 3D raymarched liquid metal scene, or use a real environment image. Since the request is ambiguous, the best is to clarify or propose.\n\nHowever, the user said \"you cant do it, thats interesting\" — maybe they are impressed that I couldn't and want me to explain why. Or it's a conversational cue. We should not be defensive. We can say: \"You're right — true photorealistic liquid metal in 2D WebGL is limited. To do it properly, you need environment maps and often 3D raymarching. I can try a more advanced approach if you want.\" Then maybe implement a better one: e.g., load an HDR environment map, or use a 3D raymarched shader.\n\nGiven we have time and tools, we can attempt a more convincing liquid metal. Options:\n\n1. **MatCap shader**: Use a spherical texture of a chrome environment and map based on normal. We can generate a matcap texture procedurally or load an image. A matcap is the easiest way to get realistic metal. We can create a canvas-generated matcap (a gradient circle with bright spots) and use it as a texture. This gives very convincing metal because the reflection is preauthored.\n\n2. **Load a real environment map**: Could fetch an HDR or LDR environment image from a URL? We have webfetch. But we'd need a CORS-friendly environment image. Could use a data URI generated from a small image? Or generate a procedural environment map on canvas.\n\n3. **3D raymarched liquid metal**: Write a fragment shader that raymarches a scene of deformed spheres/metaballs, computes normals, and uses environment/reflection. This would be true 3D liquid metal and much more convincing.\n\nGiven the user's skepticism, perhaps the best is to implement a 3D raymarched liquid metal scene. That would be a \"you can do it\" demonstration. Let's do that. But it's more complex. We can create a new site `~/raymarch-liquid-metal/index.html` with a WebGL2 fragment shader that raymarches signed distance functions for liquid metal blobs, with proper lighting and reflections. This is a different thing from the previous 2D shader.\n\nHowever, the user said \"make the same thing but with a more liquid metal vibe\" and then \"you cant do it, thats interesting\". They might want the same website/2D shader but better. Raymarching is a new thing. But it's an opportunity to show capability.\n\nWe could also improve the 2D shader using a **matcap**. A matcap would make the 2D surface look like real metal, because it fakes environment reflections with a precomputed sphere map. The normal from the height field maps to UVs on the matcap. This is a common technique in ZBrush/Blender. We can generate a matcap texture on a canvas: a radial gradient with bright spots, representing a studio lighting environment. Then the fragment shader does:\n```\nvec2 matcapUV = normal.xy * 0.5 + 0.5;\nvec3 envColor = texture(u_matcap, matcapUV).rgb;\n```\nThis is much more realistic than procedural environment. And we can still animate the height field to make liquid flow. We can generate different matcaps for different metals (mercury, gold, rose, cyber). This would be a big improvement and easier than raymarching.\n\nLet's implement matcap-based liquid metal in the existing `~/liquid-metal-site/index.html`. Steps:\n1. Generate matcap textures (canvas) for each palette and store as data URLs or `ImageData`. Or generate one dynamic matcap based on palette colors.\n2. Use a `sampler2D u_matcap` uniform. Bind the matcap texture to unit 1.\n3. In fragment shader, compute normal from height field. Then `vec2 mcUV = normal.xy * 0.5 + 0.5;` but we need to account for view. Better matcap mapping: `vec3 viewDir = normalize(vec3(uv*0.3,1)); vec3 reflected = reflect(-viewDir, normal);` and use reflected direction to sample an equirectangular or sphere map. Matcap uses view-space normal: `vec2 muv = normalize(normal).xy * 0.5 + 0.5;` Actually common matcap: `vec2 muv = vec2(normal.x, normal.y) * 0.5 + 0.5;` where normal is in view space. This gives a fixed reflection for each normal direction. For a moving surface, the normal changes and the matcap animates, looking like reflections moving.\n4. Generate the matcap image: a 256x256 canvas where color is a function of (x,y) representing a sphere with lighting. For chrome: dark edges, bright center, plus highlight spots. For gold: same but gold-tinted. We can generate one generic grayscale matcap and tint it in shader by `metalCol` / `reflCol`. Or generate colored matcaps.\n\nSimpler: generate a high-contrast grayscale matcap and multiply by palette colors in shader. The matcap should have:\n- A dark vignette around edges (Fresnel dark)\n- A bright broad area in the middle\n- A sharp white highlight spot (specular)\n- Some subtle gradients.\n\nWe can generate it as a radial gradient plus a Gaussian highlight. For example:\n```\nfor each pixel (x,y) in 256x256:\n u = (x/255)*2-1, v = (y/255)*2-1\n r = sqrt(u^2+v^2)\n // base sphere\n intensity = 1 - r^2 // bright center\n // highlight at offset\n hl = exp(-((u-0.4)^2 + (v-0.3)^2)*8)\n intensity += hl * 0.8\n // dark edges\n intensity *= smoothstep(1.1, 0.7, r)\n // add contrast\n intensity = pow(intensity, 0.6)\n color = vec3(intensity)\n```\nThen in shader, `vec3 mat = texture(u_matcap, muv).rgb; color = metalCol.rgb * mat * 2.0 + specCol.rgb * pow(mat,4.0) * 4.0;`. This will look like metal reflecting a studio.\n\nThis is a good \"you can do it\" improvement. Let's implement.\n\nWe need modify `liquid-metal-site/index.html` to:\n- Generate matcap canvas in JS and upload as texture to unit 1.\n- Add uniform `u_matcap` to fragment shader and JS.\n- Update fragment shader to use matcap for reflection instead of procedural environment.\n- Keep roughness slider (maybe not needed if matcap handles it? But roughness can blur normal or sample mipmap).\n\nActually roughness could be simulated by blending normals or using `textureLod(u_matcap, muv, roughness*4.0)` if we generate mipmaps. WebGL2 supports `textureLod` and `generateMipmap`. We can create matcap with mipmaps and use `textureLod(u_matcap, muv, roughness * 4.0)` to blur reflection. This is physically-based! Great. Then roughness slider controls LOD. At roughness 0, sharp matcap; at roughness 1, blurred.\n\nLet's design fragment shader with matcap and roughness:\n\n```\nuniform sampler2D u_matcap;\n\nvoid main() {\n ...\n float h = getHeight(uv, t);\n float e = 0.003;\n vec2 grad = ...;\n float bump = (1.0 - u_roughness) * 0.012 + 0.003; // maybe keep\n vec3 normal = normalize(vec3(-grad * bump, 1.0));\n\n // view-space matcap UV\n vec2 muv = normal.xy * 0.5 + 0.5;\n // Sample matcap with LOD for roughness\n float lod = u_roughness * 5.0;\n vec3 mat = textureLod(u_matcap, muv, lod).rgb;\n\n // Specular highlight from light\n vec3 viewDir = normalize(vec3(uv*0.35,1));\n vec3 lightDir = normalize(...);\n vec3 halfVec = normalize(viewDir + lightDir);\n float spec = pow(max(dot(normal,halfVec),0.0), (1.0-u_roughness)*128.0 + 4.0);\n\n // Fresnel\n float fresnel = 0.04 + 0.96 * pow(1.0 - max(dot(normal,viewDir),0.0), 2.5);\n\n vec4 metalCol = u_colors[1];\n vec4 reflCol = u_colors[2];\n vec4 specCol = u_colors[3];\n\n // Compose\n vec3 color = u_colorBack.rgb * 0.1;\n color += metalCol.rgb * mat * 1.8; // metal color tinted by matcap\n color += reflCol.rgb * mat * fresnel; // rim/edge reflection\n color += specCol.rgb * spec * 3.0; // light glint\n\n color = pow(color, vec3(1.2));\n fragColor = vec4(color,1.0);\n}\n```\n\nBut the matcap generation in JS: create a canvas 256x256, draw radial gradient and highlights, get `ImageData`, upload to WebGL texture with `gl.generateMipmap`. Need ensure `TEXTURE_MIN_FILTER` uses `LINEAR_MIPMAP_LINEAR` and `TEXTURE_MAG_FILTER` `LINEAR`. For `textureLod`, mipmaps must be complete. `generateMipmap` works for power-of-two? 256 is power of 2. Good.\n\nWe can generate a generic grayscale matcap and maybe colorize per palette in shader. But the matcap is grayscale; multiplying by `metalCol` tints it. For gold, `metalCol` is gold, so reflections are gold. For mercury, `metalCol` gray/white. Good. We can also add a separate `u_specColor` matcap highlight (white). The matcap includes bright highlights; `specCol` can boost them.\n\nHowever, a grayscale matcap multiplied by gold will darken the bright highlights (white * gold = gold). That's okay. For white specular, we can add `specCol.rgb * pow(mat,4.0) * 4.0` which emphasizes the brightest parts and tints them `specCol` (e.g., near-white). That gives colored metal with white hot spots. This is common.\n\nWe also want the matcap to be high-contrast. Let's generate it carefully.\n\nGenerate matcap function in JS:\n```\nfunction makeMatcap() {\n const size = 256;\n const canvas = document.createElement('canvas');\n canvas.width = size; canvas.height = size;\n const ctx = canvas.getContext('2d');\n const img = ctx.createImageData(size,size);\n for (let y=0; y476|function hexToVec4(hex) {\n 477| hex = hex.replace(/^#/, '');\n 478| if (hex.length === 3) hex = hex.split('').map(c => c+c).join('');\n...\n 495|const u = {};\n 496|[\n>497| 'u_time','u_resolution','u_pixelRatio','u_noiseTexture','u_colorBack','u_colors','u_colorsCount',\n 498| 'u_softness','u_intensity','u_noise','u_shape','u_originX','u_originY','u_worldWidth','u_worldHeight',\n 499| 'u_fit','u_scale','u_rotation','u_offsetX','u_offsetY','u_roughness'\n...\n 511|resize();\n 512|\n>513|gl.uniform1i(u.u_noiseTexture, 0);\n 514|gl.uniform4fv(u.u_colorBack, colorBack);\n 515|gl.uniform4fv(u.u_colors, colors.flat());","created_at":"2026-07-15T02:10:10.191514Z","finish_reason":null,"metrics":null},{"message_id":"907e88c3-0890-494b-9a1d-0d3f428c3f0c","node_id":846,"role":"system","content":"\n You are a Summarizer that summarizes conversation history.\nYou will be shown a conversation between the user and the assistant, a coding agent.

Below is a summary of the previous conversation thread:\nFull conversation history saved at /Users/root1/.local/share/devin/cli/summaries/history_294ff6baa2b64d6e.md.\nSummary:\n\n## Overview\nThe user asked to recreate a specific shader background from `demo.concept.dev` on a local website. The agent analyzed the provided JavaScript files (`shader-mount-DLdhuSwu.js` and `AuthBackground-BDcu6rNF.js`) to understand how the shader was implemented.\n\n## Key Details & Breadcrumbs\n- The shader background is composed of two main JavaScript files:\n - `shader-mount-DLdhuSwu.js` (aliased as `/tmp/shader-mount.js`): Contains the core WebGL shader logic, including vertex and fragment shader code, and utility functions for various effects (e.g., noise, rotation, color manipulation). (messages 63, 67)\n - `AuthBackground-BDcu6rNF.js` (aliased as `/tmp/auth-background.js`): Integrates the `shader-mount` logic into a React component called `AuthBackground` and defines specific parameters (colors, softness, intensity, shape, speed, etc.) for the background as seen on `demo.concept.dev`. It also references an image for `u_noiseTexture`. (messages 69, 71)\n- The shader uses GLSL (OpenGL Shading Language) within a WebGL context.\n- The `AuthBackground` component sets the initial parameters for the shader, including `shape:\"corners\"`, which suggests the \"corners\" effect is the one visible on the demo site.\n- The `demo.concept.dev` site uses a React SPA architecture, and the shader is a component within it.\n\n## Current State\nThe agent has successfully identified and extracted the relevant JavaScript files that implement the shader background. The next step is to create a local website that uses these files to display the shader.\n\n\nHere are some files that you edited (and perhaps there were others which were touched via shell script):\n - /tmp/probe_subs.py\n\n=== MESSAGE 2 - Assistant ===\n\n\n=== MESSAGE 3 - Tool ===\nOutput from command in shell 6f8fbe:\n`,ee=`\nvec2 rotate(vec2 uv, float th) {\n return mat2(cos(th), sin(th), -sin(th), cos(th)) * uv;\n}\n`,te=`\n float hash11(float p) {\n p = fract(p * 0.3183099) + 0.1;\n p *= p + 19.19;\n return fract(p * p);\n }\n`,ie=`\n float hash21(vec2 p) {\n p = fract(p * vec2(0.3183099, 0.3678794)) + 0.1;\n p += dot(p, p + 19.19);\n return fract(p.x * p.y);\n }\n`,re=`\n float randomR(vec2 p) {\n vec2 uv = floor(p) / 100. + .5;\n return texture(u_noiseTexture, fract(uv)).r;\n }\n`,oe=`\nvec3 permute(vec3 x) { return mod(((x * 34.0) + 1.0) * x, 289.0); }\nfloat snoise(vec2 v) {\n const vec4 C = vec4(0.211324865405187, 0.366025403784439,\n -0.577350269189626, 0.024390243902439);\n vec2 i = floor(v + dot(v, C.yy));\n vec2 x0 = v - i + dot(i, C.xx);\n vec2 i1;\n i1 = (x0.x > x0.y) ? vec2(1.0, 0.0) : vec2(0.0, 1.0);\n vec4 x12 = x0.xyxy + C.xxzz;\n x12.xy -= i1;\n i = mod(i, 289.0);\n vec3 p = permute(permute(i.y + vec3(0.0, i1.y, 1.0))\n + i.x + vec3(0.0, i1.x, 1.0));\n vec3 m = max(0.5 - vec3(dot(x0, x0), dot(x12.xy, x12.xy),\n dot(x12.zw, x12.zw)), 0.0);\n m = m * m;\n m = m * m;\n vec3 x = 2.0 * fract(p * C.www) - 1.0;\n vec3 h = abs(x) - 0.5;\n vec3 ox = floor(x + 0.5);\n vec3 a0 = x - ox;\n m *= 1.79284291400159 - 0.85373472095314 * (a0 * a0 + h * h);\n vec3 g;\n g.x = a0.x * x0.x + h.x * x0.y;\n g.yz = a0.yz * x12.xz + h.yz * x12.yw;\n return 130.0 * dot(m, g);\n}\n`;function se(t){if(Array.isArray(t))return t.length===4?t:t.length===3?[...t,1]:E;if(typeof t!=\"string\")return E;let e,r,i,l=1;if(t.startsWith(\"#\"))[e,r,i,l]=H(t);else if(t.startsWith(\"rgb\"))[e,r,i,l]=G(t);else if(t.startsWith(\"hsl\"))[e,r,i,l]=X(j(t));else return console.error(\"Unsupported color format\",t),E;return[b(e,0,1),b(r,0,1),b(i,0,1),b(l,0,1)]}function H(t){t=t.replace(/^#/,\"\"),t.length===3&&(t=t.split(\"\").map(o=>o+o).join(\"\")),t.length===6&&(t=t+\"ff\");const e=parseInt(t.slice(0,2),16)/255,r=parseInt(t.slice(2,4),16)/255,i=parseInt(t.slice(4,6),16)/255,l=parseInt(t.slice(6,8),16)/255;return[e,r,i,l]}function G(t){const e=t.match(/^rgba?\\s*\\(\\s*(\\d+)\\s*,\\s*(\\d+)\\s*,\\s*(\\d+)\\s*(?:,\\s*([0-9.]+))?\\s*\\)$/i);return e?[parseInt(e[1]??\"0\")/255,parseInt(e[2]??\"0\")/255,parseInt(e[3]??\"0\")/255,e[4]===void 0?1:parseFloat(e[4])]:[0,0,0,1]}function j(t){const e=t.match(/^hsla?\\s*\\(\\s*(\\d+)\\s*,\\s*(\\d+)%\\s*,\\s*(\\d+)%\\s*(?:,\\s*([0-9.]+))?\\s*\\)$/i);return e?[parseInt(e[1]??\"0\"),parseInt(e[2]??\"0\"),parseInt(e[3]??\"0\"),e[4]===void 0?1:parseFloat(e[4])]:[0,0,0,1]}function X(t){const[e,r,i,l]=t,o=e/360,n=r/100,a=i/100;let h,u,c;if(r===0)h=u=c=a;else{const f=(g,R,m)=>(m<0&&(m+=1),m>1&&(m-=1),m<.16666666666666666?g+(R-g)*6*m:m<.5?R:m<.6666666666666666?g+(R-g)*(.6666666666666666-m)*6:g),x=a<.5?a*(1+n):a+n-a*n,_=2*a-x;h=f(_,x,o+1/3),u=f(_,x,o),c=f(_,x,o-1/3)}return[h,u,c,l]}const b=(t,e,r)=>Math.min(Math.max(t,e),r),E=[0,0,0,1],$=\"data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\";function N(t){const e=d.useRef(void 0),r=d.useCallback(i=>{const l=t.map(o=>{if(o!=null){if(typeof o==\"function\"){const n=o,a=n(i);return typeof a==\"function\"?a:()=>{n(null)}}return o.current=i,()=>{o.current=null}}});return()=>{l.forEach(o=>o==null?void 0:o())}},t);return d.useMemo(()=>t.every(i=>i==null)?null:i=>{e.current&&(e.current(),e.current=void 0),i!=null&&(e.current=r(i))},t)}function B(t){if(t.naturalWidth<1024&&t.naturalHeight<1024){if(t.naturalWidth<1||t.naturalHeight<1)return;const e=t.naturalWidth/t.naturalHeight;t.width=Math.round(e>1?1024*e:1024),t.height=Math.round(e>1?1024:1024/e)}}async function z(t){const e={},r=[],i=o=>{try{return o.startsWith(\"/\")||new URL(o),!0}catch{return!1}},l=o=>{try{return o.startsWith(\"/\")?!1:new URL(o,window.location.origin).origin!==window.location.origin}catch{return!1}};return Object.entries(t).forEach(([o,n])=>{if(typeof n==\"string\"){const a=n||$;if(!i(a)){console.warn(`Uniform \"${o}\" has invalid URL \"${a}\".

Source it before use: `set -a; . ~/.env; set +a`\n\n## Cloudflare DNS management\n\nFor Cloudflare DNS management (adding/editing/deleting DNS records), use the **`cf` CLI** instead of `wrangler`.\nWrangler does not have DNS management capabilities, and its OAuth token doesn't work with the Cloudflare REST API for DNS operations.\n\n### Usage\n```bash\n# Check authentication status\ncf auth whoami\n\n# List DNS records for a zone\ncf dns records list -z aidenhuang.com\n\n# Add a DNS record\ncf dns records create -z aidenhuang.com --type CNAME --name devin --content \"target.example.com\" --proxied false\n\n# Delete a DNS record\ncf dns records delete -z aidenhuang.com \n```\n\nThe `cf` CLI uses the same OAuth authentication as `wrangler` and has proper DNS record permissions.\n\n## File search via fff MCP\n\nFor any file search or grep in the current git-indexed project directory, prefer the **fff** MCP tools\n(`mcp__fff__grep`, `mcp__fff__find_files`, `mcp__fff__multi_grep`) over the built-in grep/glob tools.\nfff is frecency-ranked, git-aware, and more token-efficient.\n\nRules the fff server enforces (follow them to avoid 0-result queries):\n- Search BARE IDENTIFIERS only — one identifier per `grep` query. No `load.*metadata.*Foo` style regex.\n- Don't use regex unless you truly need alternation; `.*`, `\\d+`, `\\s+` almost always return 0 results.\n- After 2 grep calls, stop and READ the top result instead of grepping with more variations.\n- Use `multi_grep` for OR logic across multiple identifiers (e.g. snake_case + PascalCase variants) in one call.\n- Have a specific name → `grep`. Exploring a topic / finding files → `find_files`.\n\nThe `fff-mcp` binary lives at `/Users/root1/.local/bin/fff-mcp` and is registered at user scope\nin `~/.config/devin/config.json`. It refuses to run in `$HOME` or `/` — it must be launched from a\nproject directory (Devin does this automatically based on cwd). Update with:\n`curl -fsSL https://raw.githubusercontent.com/dmtrKovalenko/fff.nvim/main/install-mcp.sh | bash`\n\n## X/Twitter scraping via logged-in browser session\n\nWhen I need to scrape X/Twitter data (following, followers, tweets, user info, etc.),\nthe cleanest path is to use the **Playwright MCP** browser session with my own logged-in\nx.com account, rather than spinning up twscrape's account-pool flow. twscrape needs the\n`auth_token` HttpOnly cookie which JS cannot read from `document.cookie`; the browser\nsession attaches all cookies automatically.\n\n### Flow\n1. `mcp_list_tools` on the `playwright` server, then `browser_navigate` to `https://x.com`.\n2. If not logged in, ask me to log in manually in the opened window (don't handle my password).\n3. Once on `https://x.com/home`, read `ct0` from `document.cookie`:\n `document.cookie.match(/ct0=([^;]+)/)[1]`\n4. Call X's GraphQL endpoints directly via `fetch()` inside `browser_evaluate`. Required headers:\n - `authorization: Bearer AAAAAAAAAAAAAAAAAAAAANRILgAAAAAAnNwIzUejRCOuH5E6I8xnZz4puTs%3D1Zv7ttfk8LF81IUq16cHjhLTvJu4FA33AGWWjCpTnA` (the public web-app bearer token)\n - `x-csrf-token: `\n - `x-twitter-auth-type: OAuth2Session`\n - `x-twitter-active-user: yes`\n - `content-type: application/json`\n5. Paginate timelines by reading `content.cursorType === \"Bottom\"` entries and passing\n the value back as...[913 chars truncated]..._id` may also\n be present directly.\n- `is_blue_verified` is the verified flag. `legacy.followers_count`, `legacy.description`\n still exist under `legacy`.\n- Filter timeline entries by `content.entryType === \"TimelineTimelineItem\"` and skip\n `cursor-`, `messageprompt-`, `module-`, `who-to-follow-` entryIds.\n\n### Features dict\nUse the full `GQL_FEATURES` block from twscrape's `api.py` — without it X returns\n`(336) The following features cannot be null`. Pass it URL-encoded as the `features` param.\n\n### Where things live\n- Output CSV: `~/Downloads/utilities/sdand_following.csv` (1613 rows: #, id, screen_name, name, verified, followers, bio)\n- Output JSON: `~/Downloads/utilities/sdand_following_final.json` (double-encoded JSON string; parse with `json.loads(json.loads(raw))`)\n- twscrape repo was cloned to `~/Downloads/utilities/twscrape/` for reference, then deleted after the flow was reverse-engineered. Re-clone from https://github.com/vladkens/twscrape.git if needed.\n\n## Fast Whisper transcription on Modal (A10G)\n\nFor transcribing long-form audio/video (interviews, podcasts, X/Twitter videos), use the\nutility at `~/Downloads/utilities/whisper_x/whisper_transcribe.py`. It does the full\npipeline: URL → yt-dlp download → ffmpeg audio extract → Modal volume upload →\nfaster-whisper on A10G → JSON + TXT output. Validated at **2.3 min wall clock for 65 min\nof audio** (no caching at any layer).\n\n### Usage\nShell alias (defined in `~/.zshrc`): `whisper`\n```bash\n# Transcribe an X/Twitter video (picks first playlist item)\nwhisper \"https://x.com/.../status/123\"\n\n# Pick a specific playlist item, use a smaller model\nwhisper \"https://x.com/...\" --playlist-item 2 --model-size medium\n\n# Transcribe a local audio file\nwhisper /path/to/audio.mp3 --name my-podcast\n\n# Custom output dir + keep downloaded source\nwhisper \"https://...\" --outdir ./transcripts --keep-source\n```\nTranscript text goes to stdout (pipe with `| pbcopy`); structured JSON + readable TXT\nsaved to `/.json` and `/.txt`.\n\n### Key optimizations (vs naive T4 run that took 11.7 min)\n- **A10G GPU** (~8x fp16 throughput vs T4; Modal ~$0.60/hr vs ~$0.16/hr — pennies for short jobs)\n- **`BatchedInferencePipeline`** with `batch_size=16` — batches encoder/decoder across chunks (2-4x)\n- **`beam_size=1`** (greedy) — ~2x faster, negligible WER increase for conversational speech\n- **`vad_filter=True`** — skips silence segments\n- **`compute_type=\"float16\"`** — halves memory bandwidth\n- **No caching**: `force_build=True` on apt/pip steps + unique `download_root` per run forces\n fresh image rebuild + fresh HF model download every time\n\n### Pinned versions (must match)\n- `faster-whisper==1.1.1` (provides `BatchedInferencePipeline`)\n- `ctranslate2==4.8.0`\n- Base image: `nvidia/cuda:12.6.3-cudnn-runtime-ubuntu22.04` (provides `libcublas.so.12`;\n `debian_slim` fails with `RuntimeError: Library libcublas.so.12 is not found`)\n\n### Audio prep (done automatically by the utility)\n```bash\nffmpeg -y -i input.mp4 -vn -ac 1 -ar 16000 -c:a aac -b:a 64k audio.m4a\n```\nMono 16kHz 64kbps AAC — a 65-min video (151 MB stream) becomes ~35 MB audio.\n\n### X/Twitter download notes\n- Tweet URLs can contain **playlists** (multiple videos). Use `--playlist-item N` to pick one.\n- Always use `-f bestaudio/best` to avoid downloading multi-GB high-bitrate video streams.\n- A 65-min interview's video variant can be 2.8+ GB; audio-only is ~63 MB (128 kbps).\n\n### Where things live\n- Utility: `~/Downloads/utilities/whisper_x/whisper_transcribe.py`\n- Strategy doc: `~/Downloads/utilities/whisper_x/STRATEGY.md` (full optimization breakdown)\n- Modal app (standalone): `~/Downloads/utilities/whisper_x/transcribe_fast.py`\n- Modal volume: `whisper-audio` (created automatically; holds uploaded audio files)\n- Modal profile: `aidenhuang-personal` (workspace with GPU access)\n\n\n\n\n\n\n\n\n=== MESSAGE 7 - Assistant ===\n\n\n=== MESSAGE 8 - Tool ===\nOutput from command in shell 34589f:\nTraceback (most recent call last):\n File \"\", line 9, in \nAttributeError: 'NoneType' object has no attribute 'group'\n\n\nExit code: 1\n\n=== MESSAGE 9 - Assistant ===\n\n\n=== MESSAGE 10 - Tool ===\nOutput from command in shell 950d92:\nvar V=Object.defineProperty;var M=(t,e,r)=>e in t?V(t,e,{enumerable:!0,configurable:!0,writable:!0,value:r}):t[e]=r;var s=(t,e,r)=>M(t,typeof e!=\"symbol\"?e+\"\":e,r);import{r as d,j as L}from\"./index-CCRpWqwz.js\";const I=`#version 300 es\nprecision mediump float;\n\nlayout(location = 0) in vec4 a_position;\n\nuniform vec2 u_resolution;\nuniform float u_pixelRatio;\nuniform float u_imageAspectRatio;\nuniform float u_originX;\nuniform float u_originY;\nuniform float u_worldWidth;\nuniform float u_worldHeight;\n\n\nExit code: 0\n\n=== MESSAGE 11 - Assistant ===\n\n\n=== MESSAGE 12 - Tool ===\nOutput from command in shell 40cc4f:\nvertex match: True\nhelper matches: []\n\n\nExit code: 0\n\n=== MESSAGE 13 - Assistant ===\n\n\n=== MESSAGE 14 - Tool ===\nOutput from command in shell 6f2edc:\nJ=`\nee=`\nte=`\nie=`\nre=`\noe=`\n\n\nExit code: 0\n\n=== MESSAGE 15 - Assistant ===\n\n\n=== MESSAGE 16 - Tool ===\nOutput from command in shell 8eea2d:\n\n\nExit code: 1\n\n=== MESSAGE 17 - Assistant ===\n\n\n=== MESSAGE 18 - Tool ===\nOutput from command in shell 7242f6:\nJ len 64\nee len 93\nte len 112\nie len 140\nre len 116\noe len 904\n\n\nExit code: 0\n\n=== MESSAGE 19 - Assistant ===\n\n\n=== MESSAGE 20 - Tool ===\nOutput from command in shell c026f9:\nTraceback (most recent call last):\n File \"\", line 21, in \nAttributeError: 'NoneType' object has no attribute 'group'\n\n\nExit code: 1\n\n=== MESSAGE 21 - Assistant ===\n\n\n=== MESSAGE 22 - Tool ===\nOutput from command in shell 693827:\n1:import{r as B,j as a,p as G}from\"./index-CCRpWqwz.js\";import{d as M,s as x,r as v,t as S,c as k,g as t,S as U,a as R,b as Y}from\"./shader-mount-DLdhuSwu.js\";const s={maxColorCount:7},N=`#version 300 es\n\nExit code: 0\n\n=== MESSAGE 23 - Assistant ===\n\n\n=== MESSAGE 24 - Tool ===\nOutput from command in shell df4873:\nfragment match: True\n\n\nExit code: 0\n\n=== MESSAGE 25 - Assistant ===\n\n\n=== MESSAGE 26 - Tool ===\nOutput from command in shell 8e59c5:\nWrote /tmp/concept-shader/index.html\n\n\nExit code: 0\n\n=== MESSAGE 27 - Assistant ===\n\n\n=== MESSAGE 28 - Tool ===\nCommand running in background with ID: 17fa68\n\n=== MESSAGE 29 - Assistant ===\n\n\n=== MESSAGE 30 - Tool ===\nOutput from command in shell 02e5df:\n\n\n\n\n\nConcept Shader Background\n\n\n\n\n\n597|\n598|\n\n\n=== MESSAGE 95 - Assistant ===\n\n\n=== MESSAGE 96 - Tool ===\nThe file /Users/root1/concept-shader/index.html has been updated.

A generic WebGL2 React wrapper: `ShaderMount`\n\n`assets/shader-mount-DLdhuSwu.js` is the engine. It:\n\n- Creates a WebGL2 canvas\n- Compiles a fixed vertex shader + a user-supplied fragment shader\n- Sets up a fullscreen quad\n- Handles `devicePixelRatio`, resize observers, and `requestAnimationFrame`\n- Maps JS uniforms to GLSL: `u_time`, `u_resolution`, `u_pixelRatio`, plus arbitrary user uniforms like colors, scale, rotation, images/textures\n- Supports noise textures, mipmaps, and image uniforms\n\nSo the creators don’t write a new WebGL bootstrap for every background — they just write a new fragment shader and pass it to ``.\n\n## 2. The vertex shader is generic\n\nIt computes several UV spaces (`v_objectUV`, `v_patternUV`, `v_responsiveUV`, `v_imageUV`) so the fragment shader can choose whether to treat the pattern as a fixed-ratio object, a responsive container, a tiled pattern, or an image cover/contain. That’s why the same renderer can be reused for many different shader designs.\n\n## 3. The fragment shader is hand-written GLSL\n\n`assets/AuthBackground-BDcu6rNF.js` is the actual demo background. The fragment shader:\n\n- Uses `#version 300 es` WebGL2\n- Brings in helper functions: `snoise`, `fbm` (fractal Brownian motion), `valueNoiseR`, `hash11`, `rotate`, `truchet`\n- Has 7 shape branches selected by `u_shape`:\n - wave, dots, truchet, corners, ripple, blob, sphere\n- Uses `smoothstep` and fbm to create soft, animated gradient bands\n- Mixes through a color palette array `u_colors[7]` with `u_colorsCount`, `u_softness`, and `u_intensity`\n\nThe math is classic generative/ShaderToy-style GLSL: noise layering, domain warping, signed-distance-ish shaping, and color banding.\n\n## 4. A React component presets the look\n\n`AuthBackground` is just:\n\n```js\n\n```\n\nSo a designer/front-end dev can tweak colors and shape parameters without touching GLSL.\n\n## 5. Build tooling\n\nThe site is a Vite-built React SPA:\n\n- Hashed JS chunks: `index-CCRpWqwz.js`, `AuthBackground-BDcu6rNF.js`, `shader-mount-DLdhuSwu.js`\n- ES modules with relative imports\n- Static assets served from Google Frontend (likely Google Cloud Storage behind Cloudflare or a CDN)\n\n## In short\n\nThey made it by combining:\n\n- **React** for UI/component structure\n- **Vite** for bundling\n- **WebGL2 + hand-written GLSL** for the visuals\n- **A generic `` engine** so one background shader is a drop-in fragment string + uniforms\n- **Design tokens** for colors/transforms so the same shader can be themed across environments\n\nIt’s the same workflow you’d see on ShaderToy or in generative design tools, just packaged into a production React component.\n\n=== MESSAGE 116 - User ===\nmake an animated website\n\n=== MESSAGE 117 - Assistant ===\n\n\n=== MESSAGE 118 - Tool ===\nOutput from command in shell 59ea65:\ntotal 40\ndrwxr-xr-x 3 root1 staff 96 Jul 14 17:27 .\ndrwxr-x---+ 168 root1 staff 5376 Jul 14 17:27 ..\n-rw-r--r-- 1 root1 staff 18948 Jul 14 17:27 index.html\n\n\nExit code: 0\n\n=== MESSAGE 119 - Assistant ===\n\n\n=== MESSAGE 120 - Tool ===\n\n 1|\n 2|\n 3|\n 4|\n 5|\n 6|Concept Shader Background\n 7|\n 11|\n 12|\n 13|\n 14|\n601|\n602|\n\n\n=== MESSAGE 123 - Assistant ===\n\n\n=== MESSAGE 124 - Tool ===\nOutput from command in shell c272ce:\nWrote /Users/root1/animated-site/index.html size 23760\n\n\nExit code: 0\n\n=== MESSAGE 125 - Assistant ===\n\n\n=== MESSAGE 126 - Tool ===\nCommand running in background with ID: 26243a\n\n=== MESSAGE 127 - Assistant ===\n\n\n=== MESSAGE 128 - Tool ===\nOutput from command in shell 67df27:\n:3: DeprecationWarning: Image.Image.getdata is deprecated and will be removed in Pillow 14 (2027-10-15).

The *correct* real-time trick is **matcap reflection**, and now it's in there.\n\n## What I changed\n\nSwapped the procedural environment function for a **generated matcap texture** (a sphere of studio lights) and used the surface normal to sample it. This is the same technique ZBrush, Blender, and game engines use for fast, convincing metal.\n\n### The shader now\n\n1. Generates a liquid height field (flow / ripples / chrome / blobs)\n2. Derives a normal from the height gradient\n3. Uses that normal as UVs into a **matcap sphere map**\n4. Samples the matcap with mipmaps, where the **Roughness** slider controls LOD (`textureLod(u_matcap, muv, roughness * 5.0)`)\n5. Adds a Fresnel rim and a moving specular glint\n6. Tints the reflection by the metal color\n\nThe matcap itself is drawn at runtime on a 256×256 canvas: a bright sphere with a key light, a fill light, and a dark rim. Because it's a real reflection map, the surface actually reads as chrome/mercury/gold instead of a noisy gradient.\n\n## Files\n\n- **Site:** `~/liquid-metal-site/index.html`\n- **Running at:** `http://localhost:8082/`\n- **Screenshots:** `/tmp/liquid4_1.png` … `/tmp/liquid4_4.png`\n\n## Preview stats\n\n- Min: `0` (deep shadows)\n- Max: `255` (blown specular highlights)\n- Average: `[78, 78, 81]` for Mercury\n\nI opened the page and the four shape renders in your image viewer. Drag the **Roughness** slider — at the left it's a mirror, at the right it's brushed/dull metal.\n\nFor true photorealism you'd still want an HDRI environment map or raytraced 3D, but matcap is the standard correct answer for this kind of real-time 2D liquid-metal look.","tool_calls":[],"thinking":"Now final answer.
