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

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

The missing rows from 24018 onward suggest the daemon might not be running currently, but that would affect entire recent sessions rather than just the last assistant message in specific chats. This points to either a daemon availability issue or a race condition.\n\nActually, I think I've found it — the real culprit is likely the UNIQUE constraint on (session_id, node_id) combined with INSERT OR REPLACE in the CLI. When finalizing an assistant message, the CLI replaces the row by deleting the old one and inserting a new one with a higher row_id. But in Supabase, the upsert only tracks by row_id, so the old row never gets deleted — both the stale old row and the new row persist. Then when data.ts dedupes messages by message_id, if both rows have the same node_id and message_id but different row_ids, the ordering becomes ambiguous and the last-wins logic could pick the stale one instead of the fresh one.\n\nBut wait, my diff script checked rows in Supabase against SQLite by row_id up to the watermark and found missingLocal=0, meaning no rows were missing locally. If REPLACE was happening, the old row_ids would be gone from SQLite but still in Supabase, which would show up as missingLocal > 0. So that's not it.\n\nThe data actually syncs faithfully up to the watermark, so the real issue might be row_id gaps — SQLite shows max row_id of 24827 but only 23247 rows, leaving 770 gaps. AUTOINCREMENT shouldn't create gaps unless rows are deleted or transactions roll back, which means the CLI is actively deleting rows. Those deletes don't propagate to Supabase, but my diff found no evidence of that either.\n\nThe actual race condition I'm seeing: with multiple concurrent CLI sessions writing to the same database, the daemon polls and sets its watermark based on the max committed row_id it observes. But SQLite's write locking and WAL mode serialize commits in order, so row allocation and commit happen atomically — a row allocated later can't commit before an earlier one, so out-of-order commits shouldn't happen.\n\nThe gaps are likely from deletes or rollbacks happening before the daemon syncs them, or from delete-and-reinsert cycles within the same transaction that the daemon never observes. Since data up to the watermark is perfectly consistent, the real issue is rows beyond it — the daemon probably stopped running. The timestamps suggest it halted around 11:12 UTC, which would explain why recent chat tails are missing. But the user's description of \"last assistant message not surfaced\" sounds more systematic than just a stopped daemon — it's a specific pattern where everything syncs except the final assistant message, which suggests something about the write ordering or sync sequencing for that particular message type.\n\nLooking at the read path, there's a deduplication mechanism keyed by message_id that keeps the last node when duplicates exist, but the schema uses a tree structure with parent_node_id and a main_chain_id per session. The web app fetches all nodes sorted by node_id and dedupes by message_id without respecting the tree structure, which could theoretically surface wrong messages. But that wouldn't explain a missing last message — it would show the wrong one. Since the watermark data is perfectly consistent, any missing message must be beyond the watermark, which points back to daemon stoppage. But the timing correlation is suspicious enough that I should look at actual data to see if there's a pattern I'm missing.\n\nActually, I think I've found it: the CLI streams assistant responses by inserting the node early and updating it in place as chunks arrive. The daemon polls every 2 seconds and syncs the row mid-stream with partial content. Since the watermark is row_id-based, subsequent updates to that same row never get re-synced. The final assistant message of a conversation is most vulnerable because nothing follows it to trigger a new row and force a resync. The reason my diff showed zero mismatches for rows within the watermark is probably because the user ran a bulk sync recently, which would have re-upserted everything and hidden the evidence of mid-stream captures.\n\nNow I'm noticing the state file shows last_message_row_id at 24017 but the actual max is 24827 — that's a significant gap. I should test this empirically by monitoring whether rows actually get updated in place. Since this very session I'm running in the CLI is writing to sessions.db, I can watch the \"zany-glade\" session and sample the same row's content length a few seconds apart to see if it changes, or check whether the newest assistant message rows have grown since my earlier query.The synced rows are byte-for-byte identical between SQLite and Supabase, so the daemon is working correctly. Now I'll check whether the CLI updates rows in place after insertion by observing the live session.","created_at":"2026-07-08T11:15:10.799006Z","finish_reason":"tool_calls","metrics":{"ttft_ms":7022,"total_time_ms":60779,"input_tokens":2,"output_tokens":4059,"cache_read_tokens":41661,"cache_creation_tokens":184,"tpot_ms":13.24390243902439,"tokens_per_sec":75.50644567219153}},{"message_id":"0e54786b-54c5-4242-a06f-7eb7a9b3a3ae","node_id":191,"role":"tool","content":"Output from command in shell 0b94fa:\n24840|54|20894|assistant|tool_calls\n24839|53|1014|tool|\n24838|52|1344|assistant|tool_calls\n24837|51|825|assistant|tool_calls\n24836|50|810|tool|\n24835|49|13830|assistant|tool_calls\n24834|48|6989|assistant|tool_calls\n24833|47|1222|tool|\n--- 5s later ---\n24840|54|20894|assistant\n24839|53|1014|tool\n24838|52|1344|assistant\n24837|51|825|assistant\n24836|50|810|tool\n24835|49|13830|assistant\n24834|48|6989|assistant\n24833|47|1222|tool\n\n\nExit code: 0","created_at":"2026-07-08T11:15:15.865136Z","finish_reason":null,"metrics":null},{"message_id":"e7480549-bd2d-404d-ab8d-41bf23cfa3a3","node_id":192,"role":"assistant","content":"","tool_calls":[{"id":"toolu_012wAUffXbSJrEbpn2JgJm8k","name":"write","arguments":{"file_path":"/Users/root1/devin-chats/scripts/diagnose-missing.ts","content":"#!/usr/bin/env tsx\n/** Temp diagnostic: per-session, find rows present in SQLite but missing in Supabase. */\nimport { createClient } from '@supabase/supabase-js'\nimport { readFileSync, existsSync } from 'fs'\nimport path from 'path'\nimport Database from 'better-sqlite3'\nimport { expandTilde } from '../lib/paths'\nimport { DEFAULT_DB_PATH } from '../lib/sqlite'\n\nfunction loadEnvFile() {\n const envPath = path.join(process.cwd(), '.env.local')\n if (!existsSync(envPath)) return\n for (const line of readFileSync(envPath, 'utf-8').split('\\n')) {\n const t = line.trim()\n if (!t || t.startsWith('#')) continue\n const eq = t.indexOf('=')\n if (eq === -1) continue\n if (!process.env[t.slice(0, eq).trim()]) process.env[t.slice(0, eq).trim()] = t.slice(eq + 1).trim()\n }\n}\nloadEnvFile()\n\nconst supabase = createClient(\n process.env.NEXT_PUBLIC_SUPABASE_URL!,\n process.env.SUPABASE_SERVICE_ROLE_KEY!,\n { auth: { persistSession: false } }\n)\n\nasync function main() {\n const db = new Database(expandTilde(DEFAULT_DB_PATH), { readonly: true })\n\n // All row_ids in supabase\n const sbIds = new Set()\n for (let from = 0; ; from += 1000) {\n const { data, error } = await supabase\n .from('message_nodes')\n .select('row_id')\n .order('row_id', { ascending: true })\n .range(from, from + 999)\n if (error) throw error\n for (const r of data ??

The current message I'm generating hasn't been inserted yet—that happens once this turn finishes. I'm trying to figure out the exact timing of when the database writes occur.\n\nThe real question is why some chats are missing their last assistant message in Supabase. Since rows up to the watermark match perfectly between SQLite and Supabase, the missing data must be above the watermark, which points to the daemon stopping at 02:20. But I should verify this against the actual data: for sessions fully below the watermark, check if any are missing their final assistant message. If none are, then the root cause is simply that the daemon stopped.\n\nThere's also a potential race condition in the sessions watermark logic—the daemon re-reads the max activity timestamp after upserting sessions, and if a session's last_activity_at advanced during the network call, the watermark could jump past it, leaving that session's row out of sync until it becomes active again. That would cause stale session metadata, though not missing messages. The message batch fetching looks fine with its 500-item limit and watermark update. But there's another angle I haven't fully explored yet around the daemon's long-lived prepared statements.\n\nLet me write a quick query to check for sessions where all rows are below the watermark but the last message is still missing in Supabase, and also characterize the overall message count differences per session to understand the scope of \"some chats.\"I've confirmed that rows are stable once written and the assistant message only inserts when the step completes.

after watermark 24017, which corresponds to 09:20:17 UTC—the daemon appears to have stopped syncing around that timestamp, with the .sync-state.json modification time suggesting this happened in the local timezone as well. skipped on the next sync. That's the real bug: between the final empty batch and saving state, new rows inserted aren't captured until the next daemon tick.\n\nThe user's actual symptom though — missing 70+ rows per chat, not just the final message — points back to the daemon simply not running since 02:20. The smaller race condition is theoretically possible but unlikely to explain this scale of data loss.\n\nLet me verify the write timing: checking a few idle sessions shows their final nodes are assistant messages already in SQLite, which means writes happen at turn end, not lazily on the next user message. And during active conversations, messages appear every few seconds, so the writes are prompt. This rules out a per-turn buffering issue.\n\nThe state file timestamp confirms the daemon stopped at 02:20:17 AM local time, and everything written after that — 829 rows across 4 sessions — never made it to Supabase. The daemon likely crashed, the terminal closed, or the laptop slept. I should check if there's a process manager or log file that might explain why it stopped.\n\nNow I'm realizing the user said \"some chats\" are missing their last assistant message. If the daemon has been down since 02:20, then chats active across that boundary would be truncated in Supabase, while older chats would appear complete. But I need to verify whether the session rows themselves synced — if panoramic-bicycle and zany-glade session rows are missing from Supabase, those chats wouldn't even appear in the list. Let me check the sessions table directly.\n\nAlso, I'm wondering if there was an earlier instance of this before today that got fixed by a later bulk run, or if the user ran bulk at 02:20 and never started the daemon afterward.\n\nI should check the shell history to see what commands were actually run, and look for any LaunchAgent or background process that might be keeping the sync running.I found that every missing row occurs after the state-file watermark at 2026-07-08 09:20 UTC. Now I'll check the session rows in Supabase and verify the daemon's expected running state.","created_at":"2026-07-08T11:16:45.566372Z","finish_reason":"tool_calls","metrics":{"ttft_ms":6495,"total_time_ms":48990,"input_tokens":2,"output_tokens":3132,"cache_read_tokens":48294,"cache_creation_tokens":5700,"tpot_ms":13.56800766283525,"tokens_per_sec":73.70278856336039}},{"message_id":"3b382399-e7e4-45cb-a45d-6ebae0221cf6","node_id":197,"role":"tool","content":"Output from command in shell 322a04:\n{\n \"name\": \"devin-chats\",\n \"version\": \"0.1.0\",\n \"private\": true,\n \"scripts\": {\n \"dev\": \"next dev\",\n \"build\": \"next build\",\n \"start\": \"next start\",\n \"lint\": \"next lint\",\n \"sync:bulk\": \"tsx scripts/sync-to-supabase.ts bulk\",\n \"sync:daemon\": \"tsx scripts/sync-to-supabase.ts daemon\"\n },\n \"dependencies\": {\n \"@supabase/supabase-js\": \"^2.39.0\",\n \"better-sqlite3\": \"^12.11.1\",\n \"next\": \"16.2.10\",\n \"next-themes\": \"^0.4.6\",\n \"react\": \"^19.0.0\",\n \"react-dom\": \"^19.0.0\"\n },\n \"devDependencies\": {\n \"@tailwindcss/postcss\": \"^4.0.0\",\n \"@types/better-sqlite3\": \"^7.6.13\",\n \"@types/node\": \"^20\",\n \"@types/react\": \"^19\",\n \"@types/react-dom\": \"^19\",\n \"eslint\": \"^9\",\n \"eslint-config-next\": \"16.2.10\",\n \"tailwindcss\": \"^4.0.0\",\n \"tsx\": \"^4.23.0\",\n \"typescript\": \"^5\"\n }\n}\ndiagnose-diff.ts\ndiagnose-missing.ts\nsync-to-supabase.ts\nWed Jul 8 09:20:17 UTC 2026\nWed Jul 8 02:20:17 PDT 2026\n\n\nExit code: 0","created_at":"2026-07-08T11:16:45.699912Z","finish_reason":null,"metrics":null},{"message_id":"e7f8044d-6ee6-4033-af50-459f836408fa","node_id":198,"role":"tool","content":"Output from command in shell 315f58:\nroot1 4409 20.1 1.6 1894413984 410032 ??

The last sync happened at July 8, 02:20:17 PDT when the state was saved at watermark 24017. Everything up to that point made it to Supabase intact, but anything after that sync is gone. I'm wondering why the user is describing this as missing assistant messages in specific chats rather than seeing it as a broader issue with recent conversations being incomplete.\n\nLooking at serious-fisher, the missing nodes start at node 24 (just 9 seconds after the daemon stopped) and continue through 10:22, so chats that were active when the daemon died have their tails cut off while earlier messages remain. For chats that started after the daemon stopped like zany-glade and panoramic-bicycle, the entire conversation is missing because the session rows themselves never synced to Supabase. The user probably doesn't even see those chats in their session list.\n\nThe daemon likely stopped because the user terminated it manually or closed the terminal. There's also a potential latent bug in how the daemon handles sync errors — when it opens the SQLite database and encounters a network failure, it logs and retries, but I need to trace through what happens if that error persists.\n\nThere are a couple of other subtle issues worth noting: the bulk sync sets the watermark after the loop, so rows written between the last batch and the watermark call could get skipped. Sessions use second-granularity timestamps for the watermark, so if a session updates twice in the same second, the second update might be missed until the next activity. But the empirical evidence is clear — the root cause is simply that the daemon stopped running at 02:20:17 PDT with no supervision mechanism to restart it.\n\nNow I'm verifying the Supabase data: the max row_id of 24017 matches what I'd expect, and the count of synced messages (23247) aligns perfectly with what's in SQLite, confirming nothing was synced after the watermark. The .sync-state.json modification time at 02:20 indicates that's when the sync stopped, whether the daemon crashed or was never running as a background process. I can't easily determine which from the available logs, but either way the sync halted at that moment.\n\nFor the perceived symptom — the last assistant message missing from a partially-synced session — the session row in Supabase would also be stale, showing an older last_activity timestamp than what's actually in the local database. The user would see messages up to a certain point in the chat, but nothing beyond that.\n\nNow I'll clean up the diagnostic scripts I created and prepare the root cause analysis with recommendations for fixes like restarting the daemon or adding proper supervision.The daemon stopped at the watermark time with no supervision. I'll check how the affected chats appear in Supabase and then clean up my diagnostic scripts.","created_at":"2026-07-08T11:17:20.650651Z","finish_reason":"tool_calls","metrics":{"ttft_ms":6130,"total_time_ms":34949,"input_tokens":2,"output_tokens":2065,"cache_read_tokens":53994,"cache_creation_tokens":4496,"tpot_ms":13.95593220338983,"tokens_per_sec":71.65411707554044}},{"message_id":"f3c5e8e6-299d-470f-b66b-9465030bd251","node_id":200,"role":"tool","content":"Output from command in shell e67c96:\n21|user|use crt, find all subdomains concept.dev\n22|system| The following skills can be invoked using\n23|assistant|I'll query crt.sh's Certificate Transparency logs for `conce\n24|assistant|I'll query crt.sh's Certificate Transparency logs for `conce\n25|tool|# Web Content from https://crt.sh/?q=%25.concept.dev&output=\n\n\nExit code: 0","created_at":"2026-07-08T11:17:20.680113Z","finish_reason":null,"metrics":null},{"message_id":"1e0458a9-10f7-433c-a324-0eb702422ffe","node_id":201,"role":"assistant","content":"The picture is complete.

This leaves the last visible assistant message in the database truncated, missing its tail or follow-up content. The problem occurs at turn boundaries because the daemon polls every 2 seconds, and it died right at 09:20 when this sync was happening.\n\nThe daemon likely stopped because the user closed the terminal or pressed Ctrl+C — the `.sync-state.json` modification time matches 09:20 UTC, consistent with a shutdown handler saving state. Without supervision (no launchd agent), any daemon exit silently halts syncing, so recent turns remain incomplete. There's also a latent race condition: nodes 23 and 24 share the same message_id with streaming snapshots, deduped by last-wins logic. If the daemon syncs the partial node 23 but dies before node 24 completes, the UI shows the incomplete version — exactly the \"last assistant message not surfaced\" symptom the user reported.\n\nI'm also checking whether the sync is actually complete while the daemon runs. Looking at the evidence: all rows up to the watermark match perfectly, including plenty of final assistant messages, so the daemon does sync correctly when active. However, there's another latent bug worth flagging — a race in the bulk-mode watermark logic where rows inserted between the final empty fetch and the getMaxRowId() call could be permanently skipped. The watermark is 24017 and all synced rows match exactly up to that point with matching counts, so this particular bug didn't trigger, but it's a real vulnerability given how frequently active sessions write and how long bulk syncs can take.\n\nLooking at the state file timing: it was last modified at 02:20 local time, and the watermark shows last_session_activity at 09:20:17 UTC (02:20:17 PDT). The missing rows start at 09:20:19 UTC, just two seconds after that watermark. Checking the workspace file timestamps, the user was actively developing around 02:11–02:20 — likely ran a one-shot bulk sync at 02:20 and never started the daemon, thinking sync was ongoing. The bulk sync completed and exited at 02:20:17, then nothing ran after that. The supabase count of 23247 matches exactly all SQLite rows up to 24017, which is consistent with either bulk or daemon, but the perfect timing and consistency point to bulk running once at 02:20 and the daemon never starting.\n\nThe fix is straightforward: restart the daemon to resume from watermark 24017 and catch up on everything since 02:20 local.\n\nI should present the diagnosis and RCA to the user, then offer to restart the daemon and optionally harden the setup with launchd supervision and race condition fixes.

So the sync logic itself (`row_id`-watermark upserts) is not corrupting or skipping data while running.\n\n2. **Everything missing is after one exact timestamp.** SQLite now has 24,076+ rows; Supabase stops at `row_id 24017`. Every missing row across 4 affected sessions (`first-scorpio`, `serious-fisher`, `panoramic-bicycle`, `zany-glade`) has `created_at >= 2026-07-08 09:20:19 UTC` — i.e. **02:20 local**, which is exactly `last_session_activity: 1783502417` in (mtime: Jul 8 02:20).\n\n3. **No sync process is running.** `ps` shows no `sync-to-supabase` daemon, and there's no launchd agent supervising it.\n\n4. The symptom reads as \"last assistant message missing\" because of how partial turns land. E.g. in `serious-fisher`, node 23 (a streaming snapshot of the assistant turn) was synced at 02:20, but node 24 — the finalized message that supersedes it in the `message_id` dedupe in — was written 2 seconds later and never synced.\n\n## Root cause\n\n**The sync daemon has not been running since 02:20 local.** Timeline correlation strongly suggests you ran a sync around 02:20 (env/scripts were being edited 02:11–02:18) — likely `sync:bulk`, which is one-shot and exits after saving the state file — and the `daemon` mode was never (re)started. Nothing supervises it, so the failure was silent: chats active at that moment got cut mid-turn, and every chat since is missing its tail.\n\n## Contributing factors (latent bugs worth fixing)\n\n- **No supervision / liveness signal**: the daemon dies silently with the terminal; nothing restarts it or alerts on staleness.\n- **Bulk-mode watermark race** (): `getMaxRowId()` is re-read *after* the sync loop finishes — rows inserted in that window are skipped forever. Same pattern for sessions in daemon mode (), where `getMaxActivity()` is re-read after a slow network upsert. Neither fired this time, but both are permanent-data-loss races.\n\n## Immediate remediation\n\nRunning `npm run sync:daemon` will self-heal — the watermark is at 24017, so it will backfill everything missed and catch up.\n\nWant me to:","tool_calls":[{"id":"toolu_01GYpTYL4eqfnPu4goeKJb8y","name":"ask_user_question","arguments":{"questions":[{"question":"How would you like to remediate?","header":"Remediation","multi_select":true,"options":[{"label":"Restart daemon now","description":"Start sync:daemon in the background; it backfills everything since 02:20 automatically"},{"label":"Install launchd agent","description":"Supervise the daemon so it auto-starts at login and restarts on crash"},{"label":"Fix watermark races","description":"Use the fetched batch's own max values instead of re-reading max after sync"},{"label":"Diagnosis only","description":"Stop here; you'll handle remediation yourself"}]}]}}],"thinking":"I should present the root cause analysis in a straightforward way and then check if they'd like me to provide solutions.","created_at":"2026-07-08T11:18:16.921840Z","finish_reason":"tool_calls","metrics":{"ttft_ms":4519,"total_time_ms":21800,"input_tokens":2,"output_tokens":1393,"cache_read_tokens":58904,"cache_creation_tokens":2062,"tpot_ms":12.405599425699927,"tokens_per_sec":80.60876106706787}},{"message_id":"86fe3d8e-fff3-47a4-b582-4989482bfa2c","node_id":204,"role":"tool","content":"The user submitted without answering any questions.","created_at":"2026-07-08T11:29:40.523711Z","finish_reason":null,"metrics":null},{"message_id":"7b4ddeec-98bb-477d-b442-16dc92b51b80","node_id":205,"role":"user","content":"ask me the question again","created_at":"2026-07-08T11:29:57.061549Z","finish_reason":null,"metrics":null},{"message_id":"55ded416-9825-410a-8be5-1ba2017192ef","node_id":207,"role":"assistant","content":"","tool_calls":[{"id":"chatcmpl-tool-8a590de0d34818b7","name":"ask_user_question","arguments":{"questions":[{"header":"Remediation","multi_select":true,"options":[{"description":"Start sync:daemon in the background; it backfills everything since 02:20 automatically","label":"Restart daemon now"},{"description":"Supervise the daemon so it auto-starts at login and restarts on crash","label":"Install launchd agent"},{"description":"Use the fetched batch's own max values instead of re-reading max after sync","label":"Fix watermark races"},{"description":"Stop here; you'll handle remediation yourself","label":"Diagnosis only"}],"question":"How would you like to remediate?"}]}}],"created_at":"2026-07-08T11:29:59.712790Z","finish_reason":"tool_calls","metrics":{"ttft_ms":null,"total_time_ms":2643,"input_tokens":35775,"output_tokens":157,"cache_read_tokens":204,"cache_creation_tokens":null,"tpot_ms":16.8343949044586,"tokens_per_sec":59.40219447597427}},{"message_id":"e07bd455-bfbb-442c-90b1-7813e4af0372","node_id":208,"role":"tool","content":"User answered your questions:\n{\n \"How would you like to remediate?\": {\n \"selected\": [\n \"Restart daemon now\",\n \"Install launchd agent\",\n \"Fix watermark races\"\n ]\n }\n}","created_at":"2026-07-08T11:30:04.905689Z","finish_reason":null,"metrics":null},{"message_id":"63b8e05e-fae9-4a80-8312-3f7b28b8b658","node_id":210,"role":"assistant","content":"","tool_calls":[{"id":"chatcmpl-tool-a9d6a50fc33a931b","name":"todo_write","arguments":{"todos":[{"content":"Restart sync daemon in background to backfill missing rows","status":"in_progress"},{"content":"Fix watermark races in sync-to-supabase.ts (use batch's own max values)","status":"pending"},{"content":"Install launchd agent to supervise the daemon","status":"pending"}]}}],"thinking":"Let me do all three.

Bulk mode (lines 130-133): re-reads getMaxRowId()/getMaxActivity() after sync. Fix: compute max from the data we actually synced.\n\n2. Daemon mode sessions (lines 160-163): re-reads getMaxActivity() after upsert. Fix: use max of synced sessions' last_activity_at. But last_activity_at is a string ISO timestamp in SessionRow... I need to compare. Better: track the max unix timestamp from the raw rows. But getSessions returns converted rows with ISO strings. \n\nActually the sessions query orders by last_activity_at ASC, and filters `WHERE last_activity_at > ?` with unix seconds. The converted SessionRow has ISO string. To compute the new watermark I need the unix seconds. I could either:\n- Add the raw unix value to SessionRow, or\n- Just re-query getMaxActivity() BEFORE upsert (snapshot), not after.\n\nActually the cleanest fix that matches \"use the fetched batch's own max values\": for messages, use `batch[batch.length-1].row_id` (already done correctly in daemon!). For sessions, the issue is we don't have the unix timestamp in the converted row.\n\nWait, let me re-read the daemon code. Lines 170-178 for messages already use `batch[batch.length - 1].row_id` — that's correct! The race I called out is only for sessions in daemon mode (line 163) and bulk mode (lines 131-133).\n\nFor sessions: the simplest correct fix is to snapshot max BEFORE fetching, or compute from fetched rows. Since SessionRow has ISO string last_activity_at, I can compute max from the batch and convert back to unix seconds. Or, cleaner: change getSessions to also return the raw unix timestamp. But that changes the Supabase row type... Actually SessionRow is the Postgres row type. I shouldn't add fields.\n\nAlternative: add a separate method or have getSessions return both. Simplest minimal fix: compute max from the fetched sessions' last_activity_at ISO strings, convert to unix seconds.\n\nActually, even simpler and fully correct: snapshot the current max BEFORE the fetch, then after successful upsert set state to that snapshot. No — that misses rows inserted between snapshot and fetch end... \n\nHmm. The real issue: we fetch `WHERE last_activity_at > state.last_session_activity`, upsert them, then set state to max(activity). If between fetch and upsert-completion a new session is inserted with higher activity, the re-read max would include it, and we'd advance the watermark past a row we never upserted → data loss.\n\nFix: set watermark to max of what we actually fetched (the batch), not max of the table. That's the principled fix. For sessions, I need the max unix timestamp among fetched rows.\n\nLet me add a helper that converts the ISO string back to unix seconds, or better, have getSessions return the raw value too. I'll add an internal method that returns raw rows, or just compute from ISO.\n\nActually cleanest: change `getSessions(since)` to return SessionRow[] but also expose the raw last_activity_at unix. Let me just add a parallel method `getSessionsRaw` ... no, too invasive.\n\nSimplest: parse the ISO string back. `Math.floor(new Date(iso).getTime() / 1000)`. That's exact since we generated it from unix seconds. Let me do that.\n\nFor bulk mode: \n- sessions: use max of fetched sessions' last_activity_at → unix\n- messages: use last batch's last row_id (already have `since` variable tracking it)\n\nLet me rewrite bulkSync and the sessions part of daemonSync.","created_at":"2026-07-08T11:30:39.484486Z","finish_reason":"tool_calls","metrics":{"ttft_ms":1013,"total_time_ms":11733,"input_tokens":200,"output_tokens":979,"cache_read_tokens":37094,"cache_creation_tokens":null,"tpot_ms":10.949948927477017,"tokens_per_sec":91.32462686567163}},{"message_id":"61365b43-7510-40a4-871d-16d9ee5b9ab2","node_id":226,"role":"tool","content":"The file /Users/root1/devin-chats/scripts/sync-to-supabase.ts has been updated.

Summary:\n\n## RCA\nThe sync daemon hadn't been running since 02:20 local (likely a one-shot `sync:bulk` that exited). With no supervision, the failure was silent, so every chat active at or after 02:20 lost its tail in Supabase — including finalized assistant messages whose earlier streaming snapshots *were* synced, producing the \"last assistant message missing\" symptom. Sync fidelity itself is verified perfect (byte-for-byte, 0 mismatches across 23,247 rows).\n\n## Remediation applied\n1. **Backfilled** — restarted the daemon; it caught up 981 missing rows (24017 → 25040+) and is now live-tracking.\n2. **Fixed two watermark races** in : both bulk and daemon modes now advance the watermark to the max of *what was actually upserted* instead of re-reading `MAX()` after the network call — closing the window where a concurrent insert would be skipped forever. `tsc --noEmit` passes.\n3. **Installed supervision** — runs the daemon at login, auto-restarts on crash (verified: killed -9, relaunched as new PID within 10s), and logs to `.sync-daemon.log`.\n\nUseful commands going forward:\n- `tail -f /Users/root1/devin-chats/.sync-daemon.log` — watch sync activity\n- `launchctl unload ~/Library/LaunchAgents/com.devin-chats.sync-daemon.plist` — stop\n- `launchctl load ~/Library/LaunchAgents/com.devin-chats.sync-daemon.plist` — start","tool_calls":[],"created_at":"2026-07-08T11:31:29.413786Z","finish_reason":"stop","metrics":{"ttft_ms":1258,"total_time_ms":5105,"input_tokens":301,"output_tokens":379,"cache_read_tokens":41724,"cache_creation_tokens":null,"tpot_ms":10.150395778364116,"tokens_per_sec":98.51832596828699}}]}
