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://windsurf.com/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-for-terminal` 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\":\"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\"},{\"name\":\"playwright\"}]}\n\nIMPORTANT: You MUST call `mcp_list_tools` for a server before calling `mcp_call_tool` on it.

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\":\"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\"},{\"name\":\"playwright\"}]}\n\nIMPORTANT: You MUST call `mcp_list_tools` for a server before calling `mcp_call_tool` on it.

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.

PDFs are supported in Cursor. Videos are not yet supported.\n...\nAh sorry, we were referring to 2 different things. My notion of support for PDFs was can the Agent ingest PDFs, which yes it can. As far as viewing the PDF natively in Cursor - that is not supported right now. You’ll need to rely on your system’s native PDF viewer like Preview on Mac.\n\n## 2. Bug in pdf preview - Bug Reports - Cursor - Community Forum\nURL: https://forum.cursor.com/t/bug-in-pdf-preview/40205\n\nI’m using cursor for latex writing and I found a bug in the pdf preview. My device is a MacBook Pro M3. Specifically, I found I cannot zoom or enlarge the pdf through gesture operation or click operation. To exclude personal issues, I also tried to zoom pdf on the vscode and it works, so I believe it’s a bug in cursor.\n...\n28b3\n...\n.js: 1\n...\n4.0.6367.2\n...\n3 V8: 2\n...\nOS: 1\n...\nNo - Cursor works, but with this issue\n...\nI have this same issue.

Works in vscode.\n...\nSame issue here with macbook pro where VSCode works for PDF viewing with the same setup.\n...\nI think this is related with this Scrollbar issues viewing large PDFs. The problem is that the version of VS Code is not compatible with the version of Latex-workshop.\n...\nhere is a workaround:\n...\n> I was having the same problem. I think the issue is the version of LaTeX Workshop: you are using v10.7.5, which requires VS Code 1.96.0, however, your version of Cursor (0.44.11) is using VS Code 1.93.1. image A workaround that worked for me was to downgrade the version of LaTeX Workshop to v10.7.1. I guess that when Cursor updates its version of VS Code, the problem will get automatically solved and we will be able to use again the latest version of Latex Workshop. I was having the same …\n\n## 3. cursor-viewer - Visual Studio Marketplace\nURL: https://marketplace.visualstudio.com/items?itemName=xJchen.cursor-viewer\n\nWe’re building a Cursor / VS Code extension that helps you preview almost any file directly inside the editor—including binary files and archives.\n...\nIt’s not just a viewer. By leveraging Cursor’s`@` workflow,`cursor-viewer` helps Cursor “understand” Word / Excel / PowerPoint content more reliably by converting them into formats that are easier for Cursor to read.\n...\nCursor can’t directly understand many binary formats such as Word / Excel / PPT. If you want Cursor to work from those documents, you often end up switching apps and pasting screenshots into chat—slow and error-prone.\n...\n`cursor-viewer` solves this with conversion +`@` references: since Cursor works much better with PDF and CSV, we convert your documents and integrate with the`@` workflow so Cursor can reliably read content it previously couldn’t.\n...\nPDF:`.pdf`\n...\n- Built-in rendering—no extra tools required\n\n## 4. PDFs are stale in the Cursor browser - Bug Reports - Cursor - Community Forum\nURL: https://forum.cursor.com/t/pdfs-are-stale-in-the-cursor-browser/160016\n\nCursor IDE PDF preview cache bug\n...\nThe PDFs show updated correctly when I view outside of Cursor, but inside Cursor it’s old versions i’m seeing. I already cleared the Cursor cache. I am using the Refresh button in the toolbar, and also closing the file in the Cursor browser and reopening it. The error persists.\n...\nI work mostly with PDF files in Cursor, every once in a while suddenly none of the changes that the chat says it’s making are showing in the PDF I view in Cursor. Today I checked the PDF file outside of Cursor and what do you know, the change is there. It’s just not showing the latest updated PDF file correctly in Cursor. I already cleared my Cursor cache, but it didn’t help.\n...\nthe PDF files should show the latest updated version when I push the Refresh button in the Cursor browser, the PDF file should match in Cursor what I show when I open the PDF file outside of Cursor\n...\nThis is a caching bug with the built-in PDF viewer. We’ve identified the root cause and filed it with our engineering team.\n...\nWorkaround: Click the toolbar refresh button (circular arrow icon in the browser toolbar) instead of using the keyboard shortcut. The toolbar button does a hard reload that bypasses the cache, while the keyboard shortcut does a normal reload that serves cached content.\n...\nIf that still doesn’t work in some cases, closing and reopening the PDF tab will force a completely fresh load.\n...\nI was using the Refresh button in the toolbar, as well as closing and reopening the file in the Cursor browser. Neither solution works, which is why I must change my workflow and open the PDF outside of Cursor. I have updated my post to reflect these assumed details.\n...\nThanks for confirming, Miriam, and you’re right that the toolbar refresh and close/reopen don’t resolve this.\n...\nA couple of things that should force a genuinely fresh load in the meantime:\n...\n- Open the updated PDF under a new filename (or save a copy with a new name).

PDF detected as application/octet-stream · Issue #285 · gabriel-vasile/mimetype\nURL: https://github.com/gabriel-vasile/mimetype/issues/285\n\nIf you try to open the file above, you'll see just a blank document. But, if you open the source of that file, you'll see that `%PDF-1.4` is in the 2nd line and not in the 1st one. And this is exactly the same problem that I've found in my real PDF file - the only difference is that my real PDF file works locally (i.e. with Preview/MacOS) without any issues and the one I faked actually got blank after I moved the `%PDF-1.4` to the 2nd line.\n...\nTherefore, I understand that my file is kinda corrupted (although, the customer got it from some accounting system) but it also works locally without any issues.

Email Attachments Not Sending in Windsurf App — Fix Guide | humans fix ai\nURL: https://humansfix.ai/guides/windsurf/email-attachments-not-sending\n\nEmails sent from your Windsurf-generated app arrive without their attachments, with empty attachments, or with corrupted files that can't be opened. The email itself sends successfully, but the attached file is missing or broken.\n...\nThis commonly happens with invoice PDFs, receipt exports, user-uploaded files, and generated reports that your app needs to send via email. Cascade may have configured the attachment incorrectly, pointing to a file that doesn't exist in production, using wrong encoding, or hitting size limits.\n...\nsize exceeds maximum permitted Attachment shows\n...\n: file is corrupted\n...\n- File path doesn't exist in production — Cascade used a local file path (/tmp/report.pdf) that exists during development but not in the serverless production environment\n- Wrong content encoding — Binary file content passed as a UTF-8 string instead of a Buffer, corrupting binary attachments\n- Attachment size exceeds SMTP limit — Most SMTP providers limit messages to 10-25MB total including base64 encoding overhead (which increases file size by ~33%)\n- Missing content-type header — The attachment doesn't specify the correct MIME type, causing email clients to ignore or mishandle it\n- Async file generation not awaited — The PDF or report is generated asynchronously but the email sends before the file is ready\n...\n1. Use Buffer content instead of file paths — Pass attachment content as a Buffer instead of a file path: attachments: [{ filename: 'report.pdf', content: pdfBuffer }]\n...\n2. Set content-type explicitly — Always include contentType in attachments: { filename: 'report.pdf', content: buffer, contentType: 'application/pdf' }\n...\n3. Await file generation before sending — If generating a PDF or report, await the generation and verify the buffer is not empty before attaching\n...\n4. Check total message size — Calculate base64 size (file size * 1.37) and ensure total message stays under your SMTP provider's limit\n...\n5. Log attachment details — Before sending, log the...\n\n## 3.

PDF preview broken in file viewer after 2.1.165 — local PDFs blocked by pdf-server roots gating · Issue #66250 · anthropics/claude-code\nURL: https://github.com/anthropics/claude-code/issues/66250\n\n## PDF preview broken in file viewer after 2.1.165 — local PDFs blocked by pdf-server roots gating\n...\nClicking a local PDF in the Claude Code file viewer used to render it. After updating to **2.1.165** it falls back to the text previewer:\n...\n> This file appears to contain binary data and cannot be previewed as text.\n...\nWorked in **2.1.161**. Regression in 2.1.165.\n...\n- Claude Code (desktop \"code\" mode), Windows\n- claude-code: **2.1.165** (regression vs 2.1.161)\n- Bundled plugin `pdf-viewer@inline` → PDF Server v1.7.2 (ext `ant.dir.gh.anthropic.pdf-server-mcp`)\n...\nPDF Server v1.7.2 only allows local files inside a directory present in `allowedLocalDirs`. That set is populated **only** from:\n...\n(a) CLI path args at launch, or\n(b) MCP client `roots` via `refreshRoots()`, which is gated by `clientCapabilities.roots`.\n...\nIn 2.1.165:\n\n- The `pdf-viewer` MCP launches with args `[\"dist/index.js\", \"--stdio\"]` — no directory arg.\n- The client initializes with `capabilities: {}` — **no `roots` capability** — so `refreshRoots()` returns early and never populates `allowedLocalDirs`.\n...\nResult: `allowedLocalDirs` stays empty and `validateUrl()` rejects every local PDF:\n...\n```\n[pdf-server] Local file not in allowed list: \\.pdf\n Allowed dirs:\n```\n...\n1. Open a project folder in Claude Code 2.1.165 (Windows).\n2. Click any local `.pdf` in the file viewer.\n3. \"binary data\" message appears instead of the rendered PDF.\n...\nFile viewer exposes the open workspace folder to the pdf-server (as a launch arg or via MCP `roots`) so clicked local PDFs render.\n...\nEmpty allowed list → all local PDFs rejected → text-preview fallback.\n...\nAdding the workspace dir as a launch arg to the **Desktop extension** manifest registers it (`[pdf-server] Registered local directory: ...`) and fixes the Desktop-chat side. But the file viewer uses the built-in `pdf-viewer@inline` plugin baked into `claude.exe`, which is not user-editable — so the file-viewer path cannot be fixed from user...\n\n## 5. \"view pdf\" right-click not available · Issue #2751 · James-Yu/LaTeX-Workshop\nURL: https://github.com/James-Yu/LaTeX-Workshop/issues/2751\n\n## \"view pdf\" right-click not available\n...\nHow do I view a pdf file thats not generated by a .tex document.

We’ve identified the root cause and filed it with our engineering team.\n...\nWorkaround: Click the toolbar refresh button (circular arrow icon in the browser toolbar) instead of using the keyboard shortcut.

This problem is unique to Cursor as I haven’t encountered it in VS Code.\n...\nWhen viewing large PDFs of LaTeX documents (40-60 pages), the entire document isn’t loaded into the viewer.

If that doesn't work, try logging out of Devin Desktop on the website, restarting your IDE, and logging back into Devin Desktop. Additionally, please make sure you have the latest version of Devin Desktop installed.\n \n\n \n You can cancel your paid plan by going to your Profile by clicking your icon on the top right of the [Devin Desktop website](https://windsurf.com/profile).\n\n To cancel your Pro subscription, navigate to the `Billing` page in the navigation panel on the left and click \"Cancel Plan\".\n\n To cancel your Teams subscription, navigate to the `Manage Team` page in the navigation panel on the left and click \"Cancel Plan\".\n \n\n \n As mentioned on our [security page](/admin/security#how-is-your-data-used-to-improve-devin), you can opt out of code snippet telemetry by going to your [account settings](https://windsurf.com/settings). For more information, please visit our [Terms of Service](https://windsurf.com/terms-of-service-individual).\n \n\n \n Reach out to [support](https://windsurf.com/support/) to delete your account.\n \n\n \n You can share feature requests and feedback through our community channels:\n [Reddit](https://www.reddit.com/r/windsurf/), [Discord](https://discord.com/invite/3XFf78nAx5), or [Twitter/X](https://x.com/windsurf).\n\n You can also reach out to us via our [support platform](https://windsurf.com/support/).\n \n\n\n### I'm experiencing rate limiting issues\n\nWe're subject to rate limits and unfortunately sometimes hit capacity for the premium models we work with. We are actively working on getting these limits increased and fairly distributing the capacity that we have!\n\nThis should not be an issue forever. If you get this error, please wait a few moments and try again.\n\n### Pylance or Pyright isn't working / Python syntax highlighting is broken or subpar\n\nWe've gone ahead and developed a [Pyright extension specifically for Devin Desktop](/desktop/advanced#windsurf-extensions). Please search for \"Windsurf Pyright\" or paste `@id:codeium.windsurfPyright` into the extension search.\n\n### How do I download Diagnostic logs to send to the Devin Desktop support team?\n\nYou can download diagnostic logs by going to your Cascade Panel, tapping the three dots in the top right corner, and then clicking \"Download Diagnostics\".\n\n\n \n\n\n### On MacOS, I see a pop-up: 'Devin Desktop' is damaged and cannot be opened.\n\nThis pop-up is due to a false positive in MacOS security features. You can usually resolve this by going to \"System Settings -> Privacy & Security\" and clicking \"Allow\" or \"Open anyway\" for Devin Desktop. If this fails or is not possible, try the following steps:\n\n1. Ensure that Devin Desktop is placed under your `/Applications` folder and that you are running it from there.\n2. Check your processor type: if your Mac has an Intel chip, make sure you have the Intel version. If it's Apple Silicon (like M1, M2 or M3), make sure you have the Apple Silicon version. You can select the processor type from the [Mac download page](https://windsurf.com/windsurf/download_mac).\n3. Try redownloading the DMG and reinstalling from [the official download page](https://windsurf.com/windsurf/download_mac), as the failing security feature is usually triggered on download.\n4. Make sure Devin Desktop (and the \"Devin Desktop is Damaged\" pop-up) is closed, and run `xattr -c \"/Applications/Devin.app/\"`.\n\n### I received an error message about updates on Windows, or updates are not appearing on Windows.\n\nFor example:\n\n> Updates are disabled because you are running the user-scope installation of Devin Desktop as Administrator.\n\nWe cannot auto-update Devin Desktop when it is run as Administrator. Please re-run Devin Desktop with User scope to update.\n\n### On macOS, Remote SSH fails with \"Undefined error: 0\" but SSH works from Terminal\n\nIf Remote SSH in Devin Desktop fails immediately while the same SSH connection works from Terminal, VS Code, or other applications, this is usually caused by macOS blocking Devin Desktop's local network access.\n\nIn the Remote - SSH output log (View → Output → Remote - SSH), you will see:\n\n```\ndebug1: Connecting to port 22.\nssh: connect to host port 22: Undefined error: 0\n```\n\nfollowed by `SSH server closed unexpectedly. Error code: 255`.\n\nThe `Undefined error: 0` message (rather than \"Connection refused\" or \"Network unreachable\") is the key indicator — this is the error macOS returns when an application is not granted Local Network permission under Privacy & Security.\n\nTo fix this:\n\n1. Open **System Settings → Privacy & Security → Local Network**.\n2. Find **Devin Desktop** in the list and **enable** the toggle.\n3. Restart Devin Desktop and retry the connection.\n\nIf Devin Desktop does not appear in the Local Network list, try initiating an SSH connection from Devin Desktop first to trigger the macOS permission prompt. If the prompt was previously dismissed and the toggle does not appear, deleting and reinstalling Devin Desktop will re-trigger the prompt on next launch.\n\n### What domains should I whitelist for network filters/firewalls, VPNs, or proxies?\n\nIf you're using any network filtering, firewalls, VPN services, or working in environments with restricted network access, you may experience connectivity issues with Devin Desktop. To ensure smooth operation, please whitelist the following domains in your network configuration:\n\n* \\*.codeium.com\n* \\*.windsurf.com\n* \\*.codeiumdata.com\n\n### On Linux, Devin Desktop quietly doesn't launch, or crashes on launch\n\nThis is usually due to an Electron permissions issue, which VSCode also has, and is expected when using the tarball on Linux.\n\nThe easiest way to fix it is to run the following:\n\n```bash theme={null}\nsudo chown root:root /path/to/windsurf/chrome-sandbox\nsudo chmod 4755 /path/to/windsurf/chrome-sandbox\n```\n\nYou should then be able to launch Devin Desktop. You can also just run `windsurf` with the flag `--no-sandbox`, though we don't encourage this.\n\nIf this fails, then try the below.\n\n### I received an error message saying 'Devin Desktop failed to start'\n\nWarning: deleting these folders will remove your conversation history and local settings!\n\nDelete the following folder:\n\nWindows: `C:\\Users\\\\.codeium\\windsurf\\cascade`\n\nLinux/Mac: `~/.codeium/windsurf/cascade`\n\nand try restarting the IDE.\n\n### My Cascade panel goes blank\n\nPlease reach out to us if this happens! A screen recording would be much appreciated. This can often be solved by clearing your chat history (`~/.codeium/windsurf/cascade`).\n\n### Terminal session appears stuck in Cascade\n\nIf a terminal command has finished running in the terminal but Cascade still shows the session as in progress or stuck, this can be caused by several issues:\n\n**Default terminal profile not set**\n\nThis may be caused by the default terminal profile not being explicitly set. To resolve this, you can set the default terminal profile in your Editor settings.\n\nOpen the Settings UI (Cmd/Ctrl + ,), search for \"terminal default profile\", and set the appropriate value for your operating system. Alternatively, you can add the following to your `settings.json`:\n\nFor macOS:\n\n```json theme={null}\n\"terminal.integrated.defaultProfile.osx\": \"zsh\"\n```\n\nFor Windows:\n\n```json theme={null}\n\"terminal.integrated.defaultProfile.windows\": \"PowerShell\"\n```\n\nFor Linux:\n\n```json theme={null}\n\"terminal.integrated.defaultProfile.linux\": \"bash\"\n```\n\nReplace the value with your preferred shell (e.g., `bash`, `zsh`, `PowerShell`, `Command Prompt`, etc.).\n\n**Customized zsh themes**\n\nIn some cases, a heavily customized zsh theme (for example, themes from Oh My Zsh, Powerlevel10k, or other prompt frameworks) can also cause Cascade to think a command is still running even after it finishes. To check if this is the issue:\n\n1. Open your `~/.zshrc` file in a text editor.\n2. Temporarily disable your theme by commenting out lines that set or load it, such as `ZSH_THEME=\"...\"`, `source ~/.p10k.zsh`, or `eval \"$(oh-my-posh init zsh)\"`.\n3. Save the file, restart Devin Desktop (or open a new terminal in Devin Desktop), and run a command again.\n\nIf the terminal session no longer appears stuck in Cascade, you can either keep a simpler theme in `~/.zshrc`, or create a separate, minimal zsh configuration used only by the Devin Desktop terminal so your other terminals can continue using the more complex theme.\n\n**Systemd terminal context tracking (Linux)**\n\nOn some newer Linux distributions (reported on Fedora 43 and later), the shell startup chain (`~/.bashrc` → `/etc/bashrc` → `/etc/profile.d/80-systemd-osc-context.sh`) can enable systemd \"terminal context tracking,\" which emits OSC 3008 escape sequences via `PS0` or `PROMPT_C… (231 chars truncated)\n… (6 lines truncated)\n\nFull output written to: /var/folders/d9/mzhyr7lx6xbf236j5ll9v_300000gn/T/devin-overflows-501/19754e6b/content.txt\n","created_at":"2026-07-03T07:45:46.966327Z","finish_reason":null,"metrics":null},{"message_id":"59f549ae-e737-4b0c-9690-ebed0b4d9bb8","node_id":57,"role":"assistant","content":"","tool_calls":[{"id":"functions.web_search:10","name":"web_search","arguments":{"query":"Windsurf file viewer PDF binary not supported workspace display 2025"}}],"thinking":"The docs don't mention PDF issues specifically. The user mentioned that PDFs used to open as PDFs in both Devin Desktop and Cursor. Now they open as binary encodings. This is likely because:\n\n1. Cursor: In the Agent Window (file viewer), PDFs are not supported - only text and images. But in the Editor Window, PDFs do work. The user may be using Agent Window and seeing binary.\n\n2. Devin Desktop: Similar situation - there might be a workspace viewer or Cascade panel that shows files, and it might not support PDFs. Or it could be a regression.\n\nSince the user is asking \"can you get pdfs to open as pdfs rather than the binary encodings?\" - they want to know if it's possible. I should give them actionable advice and be honest about what I can confirm.\n\nLet me also check if there's a skill or any relevant Windsurf config. But I think I've gathered enough.

After updating to **2.1.165** it falls back to the text previewer:\n...\n> This file appears to contain binary data and cannot be previewed as text.\n...\nWorked in **2.1.161**. Regression in 2.1.165.\n...\n- Claude Code (desktop \"code\" mode), Windows\n- claude-code: **2.1.165** (regression vs 2.1.161)\n- Bundled plugin `pdf-viewer@inline` → PDF Server v1.7.2 (ext `ant.dir.gh.anthropic.pdf-server-mcp`)\n...\nPDF Server v1.7.2 only allows local files inside a directory present in `allowedLocalDirs`. That set is populated **only** from:\n...\n(a) CLI path args at launch, or\n(b) MCP client `roots` via `refreshRoots()`, which is gated by `clientCapabilities.roots`.\n...\nIn 2.1.165:\n\n- The `pdf-viewer` MCP launches with args `[\"dist/index.js\", \"--stdio\"]` — no directory arg.\n- The client initializes with `capabilities: {}` — **no `roots` capability** — so `refreshRoots()` returns early and never populates `allowedLocalDirs`.\n...\nResult: `allowedLocalDirs` stays empty and `validateUrl()` rejects every local PDF:\n...\n```\n[pdf-server] Local file not in allowed list: \\.pdf\n Allowed dirs:\n```\n...\n1. Open a project folder in Claude Code 2.1.165 (Windows).\n2. Click any local `.pdf` in the file viewer.\n3. \"binary data\" message appears instead of the rendered PDF.\n...\nFile viewer exposes the open workspace folder to the pdf-server (as a launch arg or via MCP `roots`) so clicked local PDFs render.\n...\nEmpty allowed list → all local PDFs rejected → text-preview fallback.\n...\nAdding the workspace dir as a launch arg to the **Desktop extension** manifest registers it (`[pdf-server] Registered local directory: ...`) and fixes the Desktop-chat side. But the file viewer uses the built-in `pdf-viewer@inline` plugin baked into `claude.exe`, which is not user-editable — so the file-viewer path cannot be fixed from user...\n\n## 2. \"view pdf\" right-click not available · Issue #2751 · James-Yu/LaTeX-Workshop\nURL: https://github.com/James-Yu/LaTeX-Workshop/issues/2751\n\n## \"view pdf\" right-click not available\n...\nHow do I view a pdf file thats not generated by a .tex document.
