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\":\"playwright\"},{\"name\":\"fff\",\"description\":\"FFF is a fast file finder with frecency-ranked results (frequent/recent files first, git-dirty files boosted).\\n\\n## Which Tool Should I Use?\\n\\n- **grep**: DEFAULT tool. Searches file CONTENTS -- definitions, usage, patterns. Use when you have a specific name or pattern.\\n- **find_files**: Explores which files/modules exist for a topic. Use when you DON'T have a specific identifier or LOOKING FOR A FILE.\\n- **multi_grep**: OR logic across multiple patterns. Use for case variants (e.g. ['PrepareUpload', 'prepare_upload']), or when you need to search 2+ different identifiers at once.\\n\\n## Core Rules\\n\\n### 1. Search BARE IDENTIFIERS only\\nGrep matches single lines. Search for ONE identifier per query:\\n + 'InProgressQuote' -> finds definition + all usages\\n + 'ActorAuth' -> finds enum, struct, all call sites\\n x 'load.*metadata.*InProgressQuote' -> regex spanning multiple tokens, 0 results\\n x 'ctx.data::' -> code syntax, too specific, 0 results\\n x 'struct ActorAuth' -> adding keywords narrows results, misses enums/traits/type aliases\\n x 'TODO.*#\\\\d+' -> complex regex, use simple 'TODO' then filter visually\\n\\n### 2. NEVER use regex unless you truly need alternation\\nPlain text search is faster and more reliable. Regex patterns like `.*`, `\\\\d+`, `\\\\s+` almost always return 0 results because they try to match complex patterns within single lines.\\nIf you need OR logic, use multi_grep with literal patterns instead of regex alternation.\\n\\n### 3. Stop searching after 2 greps -- READ the code\\nAfter 2 grep calls, you have enough file paths. Read the top result to understand the code.\\nDo NOT keep grepping with variations. More greps != better understanding.\\n\\n### 4. Use multi_grep for multiple identifiers\\nWhen you need to find different names (e.g. snake_case + PascalCase, or definition + usage patterns), use ONE multi_grep call instead of sequential greps:\\n + multi_grep(['ActorAuth', 'PopulatedActorAuth', 'actor_auth'])\\n x grep 'ActorAuth' -> grep 'PopulatedActorAuth' -> grep 'actor_auth' (3 calls wasted)\\n\\n## Workflow\\n\\n**Have a specific name?** -> grep the bare identifier.\\n**Need multiple name variants?** -> multi_grep with all variants in one call.\\n**Exploring a topic / finding files?** -> find_files.\\n**Got results?** -> Read the top file. Don't grep again.\\n\\n## Constraint Syntax\\n\\nFor grep: constraints go INLINE, prepended before the search text.\\nFor multi_grep: constraints go in the separate 'constraints' parameter.\\n\\nConstraints MUST match one of these formats:\\n Extension: '*.rs', '*.{ts,tsx}'\\n Directory: 'src/', 'quotes/'\\n Filename: 'schema.rs', 'src/main.rs'\\n Exclude: '!test/', '!*.spec.ts'\\n\\n! Bare words without extensions are NOT constraints. 'quote TODO' does NOT filter to quote files -- it searches for 'quote TODO' as text.\\n + 'schema.rs TODO' -> searches for 'TODO' in files schema.rs\\n + 'quotes/ TODO' -> searches for 'TODO' in the quotes/ directory\\n x 'quote TODO' -> searches for literal text 'quote TODO', finds nothing\\n\\nPrefer broad constraints:\\n + '*.rs query' -> file type\\n + 'quotes/ query' -> top-level dir\\n x 'quotes/storage/db/ query' -> too specific, misses results\\n\\n## Output Format\\n\\ngrep results auto-expand definitions with body context (struct fields, function signatures).\\nThis often provides enough information WITHOUT a follow-up Read call.\\nLines marked with | are definition body context. [def] marks definition files.\\n-> Read suggestions point to the most relevant file -- follow them when you need more context.\\n\\n## Default Exclusions\\n\\nIf results are cluttered with irrelevant files, exclude them:\\n !tests/ - exclude tests directory\\n !*.spec.ts - exclude test files\\n !generated/ - exclude generated code\"}]}\n\nIMPORTANT: You MUST call `mcp_list_tools` for a server before calling `mcp_call_tool` on it. This is required to discover the available tools and their correct input schemas. Never guess tool names or arguments — always list tools first.\n","metadata":{"metrics":null,"telemetry":{"source":"sysprompt","operation":"normal"},"created_at":"2026-06-29T07:09:00.305318Z","num_tokens":null,"request_id":null,"finish_reason":null,"is_user_input":null},"message_id":"0435ce5c-2a7c-4c85-a07b-0d29d3f1997c"}],"tool_availability":{"BlockList":[{"Name":{"exact":"exit_plan_mode"}}]},"append_system_messages":[]},{"model":"glm-5-2","source":{"Session":"System"},"context":[],"lifetime":{"Unique":"core/model"},"permissions":[],"user_display":[],"footer_messages":[],"set_system_prefix":null,"tool_availability":{"AllowList":[{"Name":{"exact":"exec"}},{"Name":{"exact":"read"}},{"Name":{"exact":"edit"}},{"Name":{"exact":"grep"}},{"Name":{"exact":"glob"}},{"Name":{"exact":"exit_plan_mode"}},{"Name":{"literal":"get_output"}},{"Name":{"literal":"kill_shell"}},{"Name":{"literal":"write_to_process"}},{"Name":{"literal":"write"}},{"Name":{"literal":"notebook_read"}},{"Name":{"literal":"notebook_edit"}},{"Name":{"literal":"todo_write"}},{"Name":{"literal":"webfetch"}},{"Name":{"literal":"web_search"}},{"Name":{"literal":"ask_user_question"}},{"Name":{"literal":"run_subagent"}},{"Name":{"literal":"read_subagent"}},{"Name":{"literal":"request_scope"}},{"Name":{"literal":"mcp_call_tool"}},{"Name":{"literal":"mcp_list_servers"}},{"Name":{"literal":"mcp_list_tools"}},{"Name":{"literal":"mcp_read_resource"}},{"Name":{"literal":"skill"}}]},"append_system_messages":[{"role":"system","content":"You are powered by GLM-5.2 High.","metadata":{"metrics":null,"telemetry":{"source":"system","operation":"unknown"},"created_at":"2026-06-29T07:09:00.306538Z","num_tokens":null,"request_id":null,"finish_reason":null,"is_user_input":null},"message_id":"731787e9-6c27-49f1-baa9-86b6b0e3c127"}]},{"model":null,"source":{"Session":"System"},"context":[],"lifetime":{"Unique":"core/parallel-tool-calls"},"permissions":[],"user_display":[],"footer_messages":[],"set_system_prefix":null,"tool_availability":null,"append_system_messages":[]},{"model":null,"source":"Subagent","context":[],"lifetime":{"Unique":"core/read_only_kinds"},"permissions":[[{"Tool":{"Kind":"read"}},"Allow"],[{"Tool":{"Kind":"search"}},"Allow"],[{"Tool":{"Kind":"think"}},"Allow"]],"user_display":[],"footer_messages":[],"set_system_prefix":null,"tool_availability":null,"append_system_messages":[]},{"model":null,"source":{"Session":"System"},"context":[],"lifetime":{"Unique":"core/subagent_profiles"},"permissions":[],"user_display":[],"footer_messages":[],"set_system_prefix":null,"tool_availability":null,"append_system_messages":[{"role":"system","content":"Available subagent profiles for the `run_subagent` tool.

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\":\"playwright\"},{\"name\":\"fff\",\"description\":\"FFF is a fast file finder with frecency-ranked results (frequent/recent files first, git-dirty files boosted).\\n\\n## Which Tool Should I Use?\\n\\n- **grep**: DEFAULT tool. Searches file CONTENTS -- definitions, usage, patterns. Use when you have a specific name or pattern.\\n- **find_files**: Explores which files/modules exist for a topic. Use when you DON'T have a specific identifier or LOOKING FOR A FILE.\\n- **multi_grep**: OR logic across multiple patterns. Use for case variants (e.g. ['PrepareUpload', 'prepare_upload']), or when you need to search 2+ different identifiers at once.\\n\\n## Core Rules\\n\\n### 1. Search BARE IDENTIFIERS only\\nGrep matches single lines. Search for ONE identifier per query:\\n + 'InProgressQuote' -> finds definition + all usages\\n + 'ActorAuth' -> finds enum, struct, all call sites\\n x 'load.*metadata.*InProgressQuote' -> regex spanning multiple tokens, 0 results\\n x 'ctx.data::' -> code syntax, too specific, 0 results\\n x 'struct ActorAuth' -> adding keywords narrows results, misses enums/traits/type aliases\\n x 'TODO.*#\\\\d+' -> complex regex, use simple 'TODO' then filter visually\\n\\n### 2. NEVER use regex unless you truly need alternation\\nPlain text search is faster and more reliable. Regex patterns like `.*`, `\\\\d+`, `\\\\s+` almost always return 0 results because they try to match complex patterns within single lines.\\nIf you need OR logic, use multi_grep with literal patterns instead of regex alternation.\\n\\n### 3. Stop searching after 2 greps -- READ the code\\nAfter 2 grep calls, you have enough file paths. Read the top result to understand the code.\\nDo NOT keep grepping with variations. More greps != better understanding.\\n\\n### 4. Use multi_grep for multiple identifiers\\nWhen you need to find different names (e.g. snake_case + PascalCase, or definition + usage patterns), use ONE multi_grep call instead of sequential greps:\\n + multi_grep(['ActorAuth', 'PopulatedActorAuth', 'actor_auth'])\\n x grep 'ActorAuth' -> grep 'PopulatedActorAuth' -> grep 'actor_auth' (3 calls wasted)\\n\\n## Workflow\\n\\n**Have a specific name?** -> grep the bare identifier.\\n**Need multiple name variants?** -> multi_grep with all variants in one call.\\n**Exploring a topic / finding files?** -> find_files.\\n**Got results?** -> Read the top file. Don't grep again.\\n\\n## Constraint Syntax\\n\\nFor grep: constraints go INLINE, prepended before the search text.\\nFor multi_grep: constraints go in the separate 'constraints' parameter.\\n\\nConstraints MUST match one of these formats:\\n Extension: '*.rs', '*.{ts,tsx}'\\n Directory: 'src/', 'quotes/'\\n Filename: 'schema.rs', 'src/main.rs'\\n Exclude: '!test/', '!*.spec.ts'\\n\\n! Bare words without extensions are NOT constraints. 'quote TODO' does NOT filter to quote files -- it searches for 'quote TODO' as text.\\n + 'schema.rs TODO' -> searches for 'TODO' in files schema.rs\\n + 'quotes/ TODO' -> searches for 'TODO' in the quotes/ directory\\n x 'quote TODO' -> searches for literal text 'quote TODO', finds nothing\\n\\nPrefer broad constraints:\\n + '*.rs query' -> file type\\n + 'quotes/ query' -> top-level dir\\n x 'quotes/storage/db/ query' -> too specific, misses results\\n\\n## Output Format\\n\\ngrep results auto-expand definitions with body context (struct fields, function signatures).\\nThis often provides enough information WITHOUT a follow-up Read call.\\nLines marked with | are definition body context. [def] marks definition files.\\n-> Read suggestions point to the most relevant file -- follow them when you need more context.\\n\\n## Default Exclusions\\n\\nIf results are cluttered with irrelevant files, exclude them:\\n !tests/ - exclude tests directory\\n !*.spec.ts - exclude test files\\n !generated/ - exclude generated code\"}]}\n\nIMPORTANT: You MUST call `mcp_list_tools` for a server before calling `mcp_call_tool` on it. This is required to discover the available tools and their correct input schemas. Never guess tool names or arguments — always list tools first.\n","created_at":"2026-06-29T07:09:00.305318Z","finish_reason":null,"metrics":null},{"message_id":"92b37409-9e9f-4444-ac9e-9b3881937b6e","node_id":17,"role":"system","content":"Available subagent profiles for the `run_subagent` tool.

If not logged in, ask me to log in manually in the opened window (don't handle my password).\n3. Once on `https://x.com/home`, read `ct0` from `document.cookie`:\n `document.cookie.match(/ct0=([^;]+)/)[1]`\n4. Call X's GraphQL endpoints directly via `fetch()` inside `browser_evaluate`. Required headers:\n - `authorization: Bearer AAAAAAAAAAAAAAAAAAAAANRILgAAAAAAnNwIzUejRCOuH5E6I8xnZz4puTs%3D1Zv7ttfk8LF81IUq16cHjhLTvJu4FA33AGWWjCpTnA` (the public web-app bearer token)\n - `x-csrf-token: `\n - `x-twitter-auth-type: OAuth2Session`\n - `x-twitter-active-user: yes`\n - `content-type: application/json`\n5.

And if you're struggling with it, there is nothing wrong with you. It is actually a little unnatural for a human to be so productive all the time. But the good news is that there are systems of productivity that you can build that make being productive much easier. So, in this video, I want to share with you a productivity system that I use myself and I've been using for years and I also coach to my clients that is very simple. It is very doable by by anyone. You can fit it into a busy schedule and it really simplifies productivity. So there are four parts to the system and I'll go through each of the four parts and I'll also explain a little bit about why each of those parts works and that's important because knowing how and why something works is how you make adjustments and personalizations for yourself. So start with the first part which is just to define what productivity even means. When I was uh in my teens and and early 20s there was a lot of this productivity advice that was floating around. It was kind of the birth of the productivity guru. And what I know now is that a lot of that advice was just plain wrong or even made things worse. And so when I think about the word productivity or being productive, I used to have this connotation of being this sort of uh calculating uh super disciplined almost like a robot just being able to execute on things with no hesitation. And that's just not a very healthy or productive uh way of thinking about productivity because it doesn't really work that way. And one of the traps that I fell into and I think it's very easy to fall into is that it can be easy to just optimize things for the sake of optimizing. It's like hustle for the sake of hustle. And I really don't like that a lot of productivity advice assumes that you should be always pushing to be the best uh the best of yourself um every single day. and that every second is precious...

That puts a lot of pressure on yourself. I don't actually think it makes you more productive. And I think that is really the mentality that creates toxic productivity. And so the first most important thing to lay down to be very very clear about is that productivity is just stuff that you do that gets you towards your goals. Your goals, not anyone else's. So if your goal is just to live a chill life, that's perfectly fine. You get to decide what is a meaningful outcome for you and therefore what is productive. Being productive is not the same thing as being busy. Being productive is not the same thing as just doing more things is not the same thing as having great time management. None of these things are productive unless they are helping you live your life in the way that you want to live it. Achieving the goals that are important. So the first part about building the productivity system is just defining productivity. Most people if I say what are the goals and the outcomes that you want to achieve they can give me a list of like 10 15 different things refine that down to just two or three of what you think are the most meaningful outcomes that you want to optimize towards. So for me, I want to build great learning products that help people learn to learn and use their brain in the best way. And I want to build a successful business around that. But I want to achieve that goal while enjoying the journey and not burning out and actually feeling fulfilled in my everyday life. And that's a really important goal for me. So as a result, going out with friends, having hobbies, working out, getting enough sleep, these are all highly productive things. That's what allows me to achieve that goal and it doesn't fill me with the guilt that it used to fill me with when I wasn't clear about what productivity really means for me. So that's part one. Define productivity. The second part is to do what I call flow matching. And this is really simple. All you're going to do is write down all the tasks that you need to do for the week. And next to those tasks, you figure out how complex and cognitively involved those tasks are likely to be. And the idea is that if you were to uh draw this graph, time on the x-axis and your productivity on the y, then as your day goes on, your productivity usually starts pretty high and then you get more and more tired. And if you do something to to recover energy, uh then that productivity might dip again. But then as you do more thinking, you're going to get more tired again. And this is essentially tracking your energy level throughout the day. The ability for your brain to really focus and and do these complex tasks. So if you've got this big task that's really complicated, requires a lot of deep thinking, and you do it here or here, then your brain is not in a great position to do that. And so you're going to need to spend more time doing it, which is wasted time. It's going to be harder to get the outcome that you want. And when you do create some kind of output, the chances are that the quality of it is actually going to be lower. And so ideally, you want to do these big tasks here where you are in your cognitive peak. And when you are down here and you're a little bit more tired, this is when you should do some more of those admin tasks, the things that don't require so much concentration. And this is what flow matching means. You are matching the time of the day where you are at your cognitive peak with the actual activity that you are doing. And flow matching is what dictates what your daily schedule actually looks like. It tells you which task you're going to do when during the day in which order. And obviously within reason because you can't necessarily control uh every single task that you do during the day, but for the parts that you can control, you try to abide by this principle. And flow matching is really important because by putting your brain in the optimum state to do that task, it reduces the amount of wasted time and wasted energy. So for every hour that you're putting in, you're getting more return, more bang for your buck. And it helps to avoid what is the worst case scenario where out of the time that you have put it in, you haven't been able to reach the output or the result that you needed. And so now you're in a situation where you have to compensate for that by putting in more time and that almost always does not work. In fact, there's this uh book that I read a few years ago called diminishing returns at work written by John Pincaval. What he sort of says is that as the amount of hours you spend on work increases per week, if this is your productivity on the y-axis, again, initially as you put in more hours, your productivity goes up, but then it starts to plateau and then over time it actually goes down. So, as you put in more hours, your productivity reduces. And so, this point at which you're getting diminishing returns is at about 50 hours. And what he says in the book is that someone who is working 70 hours is actually only producing about as much output as someone that works 55 hours. So your productivity actually drops so sharply after 50 hours that the additional 15 hours uh is basically wasted time. And I personally felt this myself because I used to be working 100 120 hours a week working as a junior doctor while simultaneously running a business full-time. And then I quit medicine. I quit being a doctor and I spent all of that time just working on my business. But even though I was spending double or triple the amount of time, the actual business outcomes that I was able to create for myself didn't really change by much. And fast forward to now, I work 40 to 50 hours a week. I'm not doing those crazy hours anymore at all, but I'm more productive than I've ever been. And that is because of the time that I'm spending, a very high percentage of that time is producing really high quality work d\n\n\nExit code: 0","created_at":"2026-06-29T07:09:42.459550Z","finish_reason":null,"metrics":null},{"message_id":"e6c0e225-dfa6-4c61-8061-df063157a2f7","node_id":37,"role":"assistant","content":"","tool_calls":[{"id":"chatcmpl-tool-b3f3b6b08c2083da","name":"exec","arguments":{"command":"cd /tmp && python3 -c \"\nwith open('yt_summary.txt') as f:\n t = f.read()\nprint(t[8000:14000])\n\""}}],"created_at":"2026-06-29T07:09:44.499359Z","finish_reason":"tool_calls","metrics":{"ttft_ms":null,"total_time_ms":2038,"input_tokens":1382,"output_tokens":45,"cache_read_tokens":17480,"cache_creation_tokens":null,"tpot_ms":45.28888888888889,"tokens_per_sec":22.080471050049066}},{"message_id":"c69b1a22-a653-476a-9a10-cd838ed0f1fe","node_id":38,"role":"tool","content":"Output from command in shell c79633:\neep in flow. And flow matching makes that process much easier. So, we've now got a first part of a ritual that we can start building to form your productivity system. that Sunday evening, Saturday evening, whenever you're going to do your planning, you start by writing down the list of tasks and then flow matching it, putting that into your schedule. Now, when you do that, you're going to have some tasks that you know historically you maybe are not going to be able to complete. It might be a little ambitious. A great one is exercise. So, let's say Tuesday evening, you want to get to the gym after work. So, you schedule it in at 7:00 p.m. That is your intention. But then Tuesday evening rolls around, situations have changed and now you're not able to get to the gym anymore. And so instead, let's say you sit on the couch and by the end of the night, you're feeling terrible because you didn't do the thing that you set out to do that you know is good for you. And so for those high risk tasks that we intend to do, once we put them in our schedule, we should identify them and then move on to the third part of our productivity system, which is to create scripted actions. So scripted actions are basically predetermined decisions that you're making for yourself. And it says if X then why. So you scheduled an exercise on Tuesday evening. And so what we're going to do now is think about all the barriers or the conditions, the things that could happen that prevent you from acting on that intention. These are predictable risks. If I finish late from work and therefore I'm not able to pick up the groceries to make dinner in time and that's a risk and if I can't make dinner in time, I'm I know I'm going to choose to just make dinner and then not go to the gym. Then we would say if I finish late from work and can't pick up the groceries to make dinner, then I'm going to just get takeout that day. You're making that decision in advance, which in this example is because on that day going to the gym is more important for you. you would deem that as more productive and again that is relative to your goals and you would do that for the other risks that you can think of and by creating these scripted actions we're setting ourselves up for success. The research shows that when we use scripted actions the gap between intention and behavior i.e. you intending to do something and whether you actually do it or not that gap reduces by half which basically means that it is twice as likely that you will do what you set out to do. And this is without becoming less busy, reducing your level of responsibility. It is just by having these decisions made upfront. And the reason scripted actions are so powerful is the same reason why you get diminishing returns when you put in too many hours with work. It's the reason why you have cognitive peaks and troughs in the first place. And all of this comes to something called the preffrontal cortex and specifically a phenomenon which is preffrontal cortex fatigue. So that's PFC fatigue. Your prefrontal cortex is the part of your brain that is involved in decision-m and planning uh and executive functioning and coordination. So this is the part of the brain and the human that is more developed than any other species. Most of the really complex big tasks that you need to schedule in your day that you're flow matching, these require prefrontal cortex involvement. And your prefrontal cortex is very energy consuming and it fatigues very quickly. And the reason I'm teaching you about prefrontal cortex fatigue is that once you learn to recognize this, this is really what makes productivity easy. When you enter into prefrontal cortex fatigue, you will notice a few things. Because it is involved in decision-m, you become more reluctant to make decisions. You become increasingly lazy. If you're pushing through and still trying to work despite being in PFC fatigue, the quality of your work is going to go down. And that is a reason why when you push through too many hours, you get this diminishing return on your output because the prefrontal cortex which is responsible for that output is no longer really functioning properly. It's got nothing left to give. And so we can say that your productivity is strongly influenced by your prefrontal cortex. And so with scripted actions, what we're trying to do is instead of saying, \"Hey, we're at the end of the day. It's Tuesday evening. You've spent an entire day at work making decisions and solving problems and using your brain. Your prefrontal cortex is fatigued. And now we're coming home. We're coming home late. We didn't get the groceries. And now we have to decide and coordinate again. Are we going to get takeout? Can we afford to get takeout? If I make dinner now and do a grocery run, am I going to get time to go to the gym? If I don't go to the gym today, when will I make it up? This is a lot of complex decision-making we have to do. and your PFC is already fatigued. And so if you're in that position trying to make those decisions with that state of your brain, then you're going to feel lazy and reluctant. It is very difficult to be productive when the engine of your productivity has shut down. It is much easier to have made as many of those decisions upfront as possible with our scripted actions so that when Tuesday evening rolls around, we simply observe what has happened. I've come home late. I already decided what I'm going to do. I'm going to get take out. You just have to execute. The PFC does not need to be involved in that. It doesn't increase its level of fatigue. But now we have three parts of a productivity system, right? So we have a very clear goal of what we're optimizing towards that might update over time. And then on a Sunday evening, we are writing down all of the tasks. We're figuring out how much concentration and focus it requires. We're scheduling that. We're identifying high-risk tasks and we're creating scripted actions fo\n\n\nExit code: 0","created_at":"2026-06-29T07:09:44.548058Z","finish_reason":null,"metrics":null},{"message_id":"a8aea2a6-abf2-4a49-a8f8-aa2f1975f535","node_id":40,"role":"assistant","content":"","tool_calls":[{"id":"chatcmpl-tool-919a1562eb8304fa","name":"exec","arguments":{"command":"cd /tmp && python3 -c \"\nwith open('yt_summary.txt') as f:\n t = f.read()\nprint(t[14000:])\n\""}}],"created_at":"2026-06-29T07:09:49.427054Z","finish_reason":"tool_calls","metrics":{"ttft_ms":null,"total_time_ms":4877,"input_tokens":1356,"output_tokens":42,"cache_read_tokens":18861,"cache_creation_tokens":null,"tpot_ms":116.11904761904762,"tokens_per_sec":8.611851548082837}},{"message_id":"f28ba065-7e75-400d-9147-be600018f2f2","node_id":41,"role":"tool","content":"Output from command in shell 4ed52e:\nr them. And when you do this a few times, this process becomes very fast because you you tend to have the same scripted actions because the risks are predictable and the tasks repeat. But by taking the time to do this upfront, we are setting ourselves up for success for the entire week. When I'm coaching someone and they describe this daily grind of going uphill to create productivity every single day, then that's a red flag. That tells me that they're not setting themselves up properly because most of the productivity throughout the week is determined by the decisions that you make days ago. Now, speaking of setting yourself up for success, if you found that the insights and the things that I'm talking about in this video are useful to you, hopefully you're finding it refreshing, a little bit hopeful, not the standard toxic productivity vibe, then you may also enjoy the insights that I have in my free weekly newsletter. I'm personally big on making sure that what I teach really works. So, it has to have a strong grounding in research. I have to have had personal experience using it and I have to have seen a strong track record of it being effective for my clients that I coach. And after having done this for 14 years, teaching people how to learn and be productive, I've distilled together what I think are some of the key insights and perspectives and practical takeaways that I wish I had known when I was first starting out. These are packaged into emails that you receive once a week. I write them myself. If you're interested, I'll leave a link for you to sign up in the description below. You can cancel and unsubscribe anytime if you'd like to. But now moving on to the fourth part of your productivity system, which is to build action architecture. So when I was 18 and first getting exposed to all these thoughts around productivity and what it means to be productive, a lot of the discussion was centered around motivation. And the way that I understood it at the time was in order for you to take action that has to be preceded by motivation. And so you wait around waiting to feel motivated in order to do something. And a lot of the productivity advice was around increasing this motivation so that you can take this action. So I used to watch motivational videos and read inspirational quotes and really try to hype myself up all the time. But when you look at the research in behavioral science, you see that motivation actually only accounts for 20 to 30% of whether people actually take action or not. And really disciplined people that have a lot of self-efficacy, they do not have more motivation, they just need less motivation. So, how do you need less motivation? Well, the answer that most people give is, well, you have to turn these behaviors into habits. But the thing is it's actually really hard to build habits because and if I had just one thing that I don't like about atomic habits that James Clear wrote uh is that he doesn't really emphasize the fact that most complex behaviors are not habits. So for a moment don't think about the word habit. Instead, I want you to think about the word Q because building action architecture is all about Q's. A Q is a trigger that you interact with in your environment that prompts a certain kind of response. And that response hopefully is the desired action or behavior. So, let's say that you want to go for a run. Well, a cue could be having your running shoes right by the door. packing your running clothes so that you can get changed straight after work. Creating a nice tidy workspace for yourself that's free of distractions. What we want to do is we want to create as many cues as possible that lead to a desired behavior while removing the cues that take us away from that behavior. These are our distractions. In my experience coaching people on productivity, the most disciplined, most productive people that I work with, they take this really seriously. When they intend to do something and it doesn't go as intended, they don't internalize that as, oh, here's another example of me failing. Here's evidence of the fact that I'm not a productive person. They use that as feedback to ask themselves, what was the cue that was present that distracted me and pulled me away? How could I remove that? or what is a cue that I could place that was missing that would make it easier for me to naturally go towards that behavior and they think about this a lot whereas people that chronically struggle with productivity they do the bare minimum for this they set up a few cues it doesn't work and they say h it's not working for me but the process of optimizing your environment creating the right cues creating the architecture that allows you to take action this is a process that takes iterations weeks weeks, maybe months of experimenting and reflecting so that it eventually gets easier and easier and easier to just naturally become productive. And by doing this, we are shifting the focus from motivation dependent productivity to Q dependent productivity. And it is crucial to make this shift because only when you have Qependent actions are you able to build habits. This is what I was mentioning before in that most complex behaviors are not habits. If the behavior that you want is to eat more healthy or to exercise more, these are not single behaviors. These are a series of complex decisions and considerations and multiple behaviors that come together and they come together differently at different meals and at different times and depending on your energy level. Your brain can't take all of that and just turn all of that into a habit. From your brain's perspective, in order for something to become a habit, there has to be a very clear cue and a response to that Q. So, while it might struggle with become more healthy, exercise more, instead turning that into when I walk out my door and see the pull-up bar attached to my door frame, I'm going to do five pull-ups. That can become a habit. It could even be an emotional, psychological cue. When I notice that I'm feeling lazier, my prefrontal cortex is more fatigued. Instead of what I normally do, my existing habit, which is to sit on the couch, scroll for for 5 hours, and feel like crap. Uh, instead, I'm going to go for a short walk. I'm going to do a 3 minute stretch. You can see that the pairing of the action and the cue is very clear and very specific. And so the time it takes for you to develop a habit is strongly influenced by how clear and specific that Q response pairing is. When you have multiple different cues all going towards slightly different responses, your brain doesn't really know how to turn that into a habit. And so it takes a much longer time for the habit to emerge, if ever. So by focusing on building this action architecture and moving from motivation dependent to really thinking actively about the cues then we start naturally forming much clearer and tighter Q to response pairings which means that these become habits much faster. And once something becomes a habit it does not use the prefrontal cortex anymore. It's a different part of the brain. So now it no longer requires your prefrontal cortex to have the energy for you to be productive. That productive behavior is running on autopilot. Most people understand that theory. What they don't understand is the requirements to build the habit in the first place, which is this Q response pairing. So what does building the action architecture look like as part of your productivity system? So this means that on that Sunday evening, you're writing down your tasks, you're flow matching, you're creating your scripted actions, and you're also asking yourself, what are the steps between intending to do it and actually doing it? And how many of those steps can I do? Can I put in place? Can I make it easier for me to do right now? You identify the distracting cues, you go and remove them. You identify good cues that stimulate the behavior, you go and put them in place. or you schedule time in your calendar to set yourself up for that. Remember that a large part of the productivity you feel today has been dictated by what you did to set yourself up for success in the days before. And again, as you continue to do this week by week, it gets faster and easier to set up that action architecture and plant those cues because those tasks and those habits that you're trying to build, they're usually repeating. So, you already know what you need to set up and those cues are already there as long as you didn't move them away. They still exist and all you're doing is you're refining it. You're adding more cues. You're tweaking it a little bit and optimizing it week by week. And so, this entire system takes half an hour. You use it once a week and it makes being productive for the rest of that week so much easier. Now there is sort of a sneaky fifth part of this productivity system which is what happens if our prefrontal cortex never recovers. What happens if our graph of productivity doesn't look like this where each day we're tired and we go to sleep and we wake up rested and then we you know burn through our energy again. What if instead it just looks like this and we can barely remember back when we were actually energized and we didn't feel fatigued and we didn't feel lazy. What that usually means is that you have been in a chronic state of prefrontal cortex fatigue and that usually happens because of inadequate recovery. And so the fifth part of the productivity system is optimizing your recovery. The easy answer to give is to say just get more sleep. But actually prefrontal cortex fatigue does not necessarily recover with sleep. This is why even despite having great sleep, you may still feel tired. And there is a science to recovery. There is a checklist of things that if you do allows your brain to see that as valid recovery and even when you can't get enough sle… (272 chars truncated)\n… (1 lines truncated)\n\nExit code: 0\n\nFull output written to: /var/folders/d9/mzhyr7lx6xbf236j5ll9v_300000gn/T/devin-overflows-501/bfdb9c34/content.txt\n","created_at":"2026-06-29T07:09:49.479374Z","finish_reason":null,"metrics":null},{"message_id":"03980a3e-bb15-4c6a-9229-46a35f50df07","node_id":43,"role":"assistant","content":"","tool_calls":[{"id":"chatcmpl-tool-b8635bdc1a86ba48","name":"read","arguments":{"file_path":"/var/folders/d9/mzhyr7lx6xbf236j5ll9v_300000gn/T/devin-overflows-501/bfdb9c34/content.txt"}}],"created_at":"2026-06-29T07:09:51.473231Z","finish_reason":"tool_calls","metrics":{"ttft_ms":null,"total_time_ms":1992,"input_tokens":2176,"output_tokens":50,"cache_read_tokens":20216,"cache_creation_tokens":null,"tpot_ms":39.84,"tokens_per_sec":25.100401606425702}},{"message_id":"e7931599-40e3-4216-85ea-920e13d57dc7","node_id":44,"role":"tool","content":"\n 1|Output from command in shell 4ed52e:\n 2|r them.

Here's the summary:\n\n## Summary: \"Productivity is Hard Until You Build Systems Like This\" — Justin Sung (24:25)\n\nJustin Sung shares a simple, weekly productivity system he uses and coaches to clients. The core thesis: productivity shouldn't depend on daily willpower or \"hustle\" — it should be set up in advance so that doing the right thing becomes the path of least resistance.\n\n### The 4 (+1) Part System\n\n**1. Define productivity (for yourself)**\nProductivity ≠ being busy or having great time management. It means doing stuff that moves you toward *your* goals — not anyone else's. Refine your goal list down to 2–3 meaningful outcomes. For Justin, that's building great learning products + a successful business *while enjoying the journey and not burning out*. Under that definition, going out with friends, hobbies, sleep, and exercise are all \"productive\" — which removes the guilt that comes from toxic productivity advice.\n\n**2. Flow matching**\nWrite down all weekly tasks and rate how cognitively demanding each is. Your brain has a daily energy curve — high at the start, dipping as you use it, recovering after breaks, then dipping again. Schedule deep/complex work during your cognitive peak, and admin/low-focus tasks during the troughs. This reduces wasted time and prevents the worst case: putting in hours but producing nothing usable, then \"compensating\" with even more hours.\n\nKey supporting point: John Pencavel's research in *Diminishing Returns at Work* — productivity plateaus around 50 hrs/week and then *declines*. Someone working 70 hrs produces about as much as someone working 55 hrs. Justin personally felt this working 100–120 hrs/week as a junior doctor while running a business — cutting to 40–50 hrs made him more productive, not less.\n\n**3. Scripted actions (if-then plans)**\nFor high-risk tasks (e.g. \"go to the gym Tuesday at 7pm\"), pre-decide what you'll do when predictable barriers arise. Example: *\"If I finish work late and can't get groceries, then I'll order takeout so I can still go to the gym.\"* Research shows scripted actions roughly **double** the likelihood you'll follow through — they halve the intention–behavior gap — without making you less busy.\n\nThe mechanism: **prefrontal cortex (PFC) fatigue**. The PFC handles decision-making, planning, and executive function. It's energy-hungry and fatigues fast. By Tuesday evening after a full workday, your PFC is drained — asking it to re-decide \"takeout vs cook vs gym vs make it up later\" is exactly when you'll feel lazy and bail. Pre-deciding moves that work to a fresh-brain moment (Sunday planning), so at execution time you just *observe and execute* — no PFC required.\n\n**4. Build action architecture (cues, not motivation)**\nMotivation only accounts for ~20–30% of whether people act. Disciplined people don't have *more* motivation — they *need less*, because they engineer their environment.\n\nThe key concept is **cues**: triggers in your environment that prompt a specific response. Running shoes by the door, gym clothes packed, a clean distraction-free workspace. Add cues that lead to desired behaviors; remove cues that lead to distractions.\n\nJustin's critique of *Atomic Habits*: it under-emphasizes that **most complex behaviors (eat healthy, exercise more) are not habits** — they're bundles of decisions that vary by meal/time/energy. Your brain can't turn that mush into a habit. To build a habit you need a *clear, specific cue → response pairing*: \"When I walk out my door and see the pull-up bar, I do 5 pull-ups.\" Or even an internal cue: \"When I notice I'm feeling lazy/PFC-fatigued, instead of doomscrolling I take a 3-minute walk.\" Tighter pairings → habits form faster. And once something is a habit, it runs on a different brain region — **no PFC required**, so it survives even when you're drained.\n\nThe most productive people he coaches treat a missed intention as *feedback* — \"what cue distracted me, what cue was missing?\" — not as evidence they're a failure. People who chronically struggle set up a few cues, give up when it doesn't work instantly, and conclude \"it doesn't work for me.\" In reality, building action architecture takes weeks-to-months of iteration.\n\n**5. (Sneaky fifth) Optimize recovery**\nIf your energy graph never rebounds — you can't remember the last time you felt actually energized — you're in **chronic PFC fatigue** from inadequate recovery. Crucially, PFC fatigue doesn't always recover with sleep alone; there's a science/checklist to what your brain registers as \"valid recovery.\" Justin punts the details to a separate video on the science of recovery.\n\n### The weekly ritual (puts it all together)\nOn Sunday evening (~30 min):\n1. Write down all tasks for the week\n2. Flow-match them into your schedule by cognitive demand\n3. Identify high-risk tasks and write if-then scripted actions\n4. For each task, ask: what steps sit between intending and doing? Remove distracting cues, add helpful cues, or schedule time to set them up.\n\nBecause tasks and risks repeat week to week, this gets fast over time — you're mostly refining existing cues and scripts. The framing throughout: **most of the productivity you feel today was determined by decisions you made days ago**, not by today's willpower.","tool_calls":[],"created_at":"2026-06-29T07:10:21.921379Z","finish_reason":"stop","metrics":{"ttft_ms":1441,"total_time_ms":28976,"input_tokens":744,"output_tokens":1189,"cache_read_tokens":22964,"cache_creation_tokens":null,"tpot_ms":23.15811606391926,"tokens_per_sec":43.18140548392954}}]}
