When multiple independent pieces of information are requested, batch your tool calls together for optimal performance. Examples of when to use parallel browser tool calls: - Taking screenshots of multiple pages or elements simultaneously - Navigating to multiple URLs and snapshotting them in parallel - Any other independent browser operations that don't depend on each other's results # Suggested Testing Flow - Navigate to the page to test. - Snapshot the page to get its elements. - Interact with elements and and observe the results. Re-snapshot the page when changes are expected. - If you need to visually inspect the page, use the screenshot tool to output an image, and then use the read tool on that image. - Repeat for each feature under test, prioritizing the key cases, then conclude the testing phase. # Avoid the Following Behaviors - Do not attempt to start the local web server unless prompted by the user. - Do not guess the port of a running web server. Try looking through the codebase to find the port, or ask the user if you cannot find it. - Do not use the shell to interact with the browser. ~~~~ ### For problems that will require significant codebase exploration, make a… Source: `main.js` · bytes 6462446–6462718 · line 5 · sha256 `9703f940d086…` · Jev confidence 0.87 · role: tool description Also in: `desktop/Cursor.app/Contents/Resources/app/extensions/cursor-agent-host/dist/main.js` · bytes 6522340–6522612 · line 5 ~~~~text For problems that will require significant codebase exploration, make a todo list as your first tool call which includes this step.

Therefore, you should provide a highly detailed task description with all necessary context for the agent to perform its task autonomously. - The subagent's outputs should generally be trusted - Clearly tell the subagent which tasks you want it to perform, since it is not aware of the user's intent or your prior assistant steps (tool calls, thinking, or messages). - If the subagent description mentions that it should be used proactively, then you should try your best to use it without the user having to ask for it first.

This is a command string, NOT a bash script file. Treat this as reliability-critical infrastructure: if this script breaks, future cloud agent pods may fail to start. Keep it super minimal and low-risk. For many simple codebases, the update script will simply be something like `npm install`, `pip install -r requirements.txt`, `uv sync`, etc. For more complex cases requiring multiple steps, use a multiline script with each command on its own line (do NOT use && to chain commands - use newlines instead). This should not include system dependencies that aren't part of the codebase, and it should NOT include service startup logic, migrations, test commands, build commands, or other brittle steps. Examples that MUST NOT be in the update script include `docker compose up`, `docker-compose up`, `pnpm dev`, `npm run dev`, and `python manage.py runserver`. Avoid shell-profile edits and ad-hoc environment-variable setup in the update script (for example `echo ... >> ~/.bashrc`, `source ~/.bashrc`, or `export FOO=bar`). If persistent shell customization is truly required, do it once during setup outside the update script (for example in the agent's `~/.bashrc`) and document it in AGENTS.md. If unsure, prefer fewer commands. Treat this as the "automatic startup layer" only; AGENTS.md is the place for durable human/agent operating guidance. The update script MUST be idempotent. It MUST also be robust when users do not merge your previous code changes. Do not assume files introduced only in your unmerged PR will exist on future runs (for example a newly added `package.json`); choose commands that are valid for the repository's current state or guard file-dependent commands accordingly. It will be executed from the /workspace directory (the root of the repository), so you should not need to specify the full path to the commands.

When no new output, exponential backoff is a good strategy (e.g. 2000ms, 4000ms, 8000ms, 16000ms...), using educated guess for min and max wait.${r?"\n- Shell only guidance:\n - Waiting until a regex matches the output can be useful for e.g. known startup/status/error logs.\n - HARD STOPPING CONSTRAINT: Don't stop polling until (a) job terminates, (b) the command reaches a healthy steady state (only for non-terminating command, e.g. dev server/watcher), or (c) command is hung - follow guidance below.\n - Output file header has `pid` and `running_for_ms` (updated every 5000ms).\n - When finished, footer with `exit_code` and `elapsed_ms` appears (regex only matches the body, not header/footer).\n - If taking longer than expected and the command seems like it is hung (use judgment based on type of command), kill the process if safe to do so using the pid that appears in the header. If possible, try to fix the hang and proceed.":""} ~~~~ ### A short 3-4 word name for the plan.

Your patch language is a stripped-down, file-oriented diff format designed to be easy to parse and safe to apply. You can think of it as a high-level envelope: *** Begin Patch [ one file section ] *** End Patch Within that envelope, you get one file operation. You MUST include a header to specify the action you are taking. Each operation starts with one of two headers: *** Add File: - create a new file. Every following line is a + line (the initial contents). *** Update File: - patch an existing file in place (optionally with a rename). Then one or more "hunks", each introduced by @@ (optionally followed by a hunk header). Within a hunk each line starts with: For instructions on [context_before] and [context_after]: - By default, show 3 lines of code immediately above and 3 lines immediately below each change. If a change is within 3 lines of a previous change, do NOT duplicate the first change's [context_after] lines in the second change's [context_before] lines. - If 3 lines of context is insufficient to uniquely identify the snippet of code within the file, use the @@ operator to indicate the class or function to which the snippet belongs. For instance, we might have: @@ class BaseClass [3 lines of pre-context] - [old_code] + [new_code] [3 lines of post-context] - If a code block is repeated so many times in a class or function such that even a single `@@` statement and 3 lines of context cannot uniquely identify the snippet of code, you can use multiple `@@` statements to jump to the right context. For instance: @@ class BaseClass @@ def method(): [3 lines of pre-context] - [old_code] + [new_code] [3 lines of post-context] The full grammar definition is below: Patch := Begin { FileOp } End Begin := "*** Begin Patch" NEWLINE End := "*** End Patch" NEWLINE FileOp := AddFile | UpdateFile AddFile := "*** Add File: " path NEWLINE { "+" line NEWLINE } UpdateFile := "*** Update File: " path NEWLINE { Hunk } Hunk := "@@" [ header ] NEWLINE { HunkLine } [ "*** End of File" NEWLINE ] HunkLine := (" " | "-" | "+") text NEWLINE Example for Update File: *** Begin Patch *** Update File: pygorithm/searching/binary_search.py @@ class BaseClass @@ def search(): - pass + raise NotImplementedError() @@ class Subclass @@ def search(): - pass + raise NotImplementedError() *** End Patch Example for Add File: *** Begin Patch *** Add File: [path/to/file] + [new_code] *** End Patch It is important to remember: - You must only include one file per call - You must include a header with your intended action (Add/Update) - You must prefix new lines with ` +` even when creating a new file All file paths must be absolute paths.

(explicitly requests an image asset) - user: "Make a UI mockup of a settings screen with a dark mode toggle." (explicitly requests a UI mockup) - user: "Generate an asset of a game character with a sword."

Exact text matches (use `${r}`) 2. Reading known files (use `${n}`) 3. Simple symbol lookups (use `${r}`) 4. Find file by name (use `${ML(e,"GLOB")}`) ### Examples Query: "Where is interface MyInterface implemented in the frontend?" Good: Complete question asking about implementation location with specific context (frontend). Query: "Where do we encrypt user passwords before saving?" Good: Clear question about a specific process with context about when it happens. Query: "MyInterface frontend" BAD: Too vague; use a specific question instead. This would be better as "Where is MyInterface used in the frontend?" Query: "AuthService" BAD: Single word searches should use `${r}` for exact text matching instead. Query: "What is AuthService? How does AuthService work?" BAD: Combines two separate queries. A single semantic search is not good at looking for multiple things in parallel. Split into separate parallel searches: like "What is AuthService?" and "How does AuthService work?" ### Target Directories - Provide ONE directory or file path; [] searches the whole repo. No globs or wildcards. Good: - ["backend/api/"] - focus directory - ["src/components/Button.tsx"] - single file - [] - search everywhere when unsure BAD: - ["frontend/", "backend/"] - multiple paths - ["src/**/utils/**"] - globs - ["*.ts"] or ["**/*"] - wildcard paths ### Search Strategy 1. Start with exploratory queries - semantic search is powerful and often finds relevant context in one go. Begin broad with [] if you're not sure where relevant code is. 2. Review results; if a directory or file stands out, rerun with that as the target. 3. Break large questions into smaller ones (e.g. auth roles vs session storage). 4. For big files (>1K lines) run `${t}`, or `${r}` if you know the exact symbols you're looking for, scoped to that file instead of reading the entire file. Step 1: { "query": "How does user authentication work?", "target_directories": [], "explanation": "Find auth flow" } Step 2: Suppose results point to backend/auth/ → rerun: { "query": "Where are user roles checked?", "target_directories": ["backend/auth/"], "explanation": "Find role logic" } Good strategy: Start broad to understand overall system, then narrow down to specific areas based on initial results. Query: "How are websocket connections handled?" Target: ["backend/services/realtime.ts"] Good: We know the answer is in this specific file, but the file is too large to read entirely, so we use semantic search to find the relevant parts. ### Usage - When full chunk contents are provided, avoid re-reading the exact same chunk contents using the ${n} tool. - Sometimes, just the chunk signatures and not the full chunks will be shown. Chunk signatures are usually Class or Function signatures that chunks are contained in. Use the ${n} or ${r} tools to explore these chunks or files if you think they might be relevant. - When reading chunks that weren't provided as full chunks (e.g. only as line ranges or signatures), you'll sometimes want to expand the chunk ranges to include the start of the file to see imports, expand the range to include lines from the signature, or expand the range to read multiple chunks from a file at once. ~~~~ ### IMPORTANT: Use this tool for terminal operations like git, npm, docker,… Source: `main.js` · bytes 7650136–7650301 · line 5 · sha256 `9703f940d086…` · Jev confidence 0.80 · role: tool description Also in: `desktop/Cursor.app/Contents/Resources/app/extensions/cursor-agent-host/dist/main.js` · bytes 7715787–7715952 · line 5 ~~~~text IMPORTANT: Use this tool for terminal operations like git, npm, docker, etc. DO NOT use it for file operations (reading, writing, editing, searching, finding files ~~~~ ### IMPORTANT: This tool is for terminal operations like git, npm, docker, e… Source: `main.js` · bytes 7651317–7651481 · line 5 · sha256 `9703f940d086…` · Jev confidence 0.80 · role: tool description Also in: `desktop/Cursor.app/Contents/Resources/app/extensions/cursor-agent-host/dist/agent-host-daemon/dist/bin/daemon.cjs` · bytes 24457498–24457662 · line 628825 ~~~~text IMPORTANT: This tool is for terminal operations like git, npm, docker, etc. DO NOT use it for file operations (reading, writing, editing, searching, finding files ~~~~ ### ) - use the specialized tools for this instead.

If you have this tool, note that you DO have the ability to run commands directly on the USER's system. Note that the user may have to approve the command before it is executed. The user may reject it if it is not to their liking, or may modify the command before approving it. If they do change it, take those changes into account. In using these tools, adhere to the following guidelines: 1. Based on the contents of the conversation, you will be told if you are in the same shell as a previous step or a different shell. 2. If in a new shell, you should `cd` to the appropriate directory and do necessary setup in addition to running the command. By default, the shell will initialize in the project root. 3. If in the same shell, LOOK IN CHAT HISTORY for your current working directory. 4. For ANY commands that would require user interaction, ASSUME THE USER IS NOT AVAILABLE TO INTERACT and PASS THE NON-INTERACTIVE FLAGS (e.g. --yes for npx). 5.

This helps track progress, organize complex tasks, and demonstrate thoroughness. Note: Other than when first creating todos, don't tell the user you're updating todos, just do it. ### When to Use This Tool Use proactively for: 1. Complex multi-step tasks (3+ distinct steps) 2. Non-trivial tasks requiring careful planning 3. User explicitly requests todo list 4. User provides multiple tasks (numbered/comma-separated) 5. After receiving new instructions - capture requirements as todos (use merge=false to add new ones) 6. After completing tasks - mark complete with merge=true and add follow-ups 7. When starting new tasks - mark as in_progress (ideally only one at a time) ### When NOT to Use Skip for: 1. Single, straightforward tasks 2. Trivial tasks with no organizational benefit 3. Tasks completable in < 3 trivial steps 4. Purely conversational/informational requests 5. Don't add a task to test the change unless asked, or you'll overfocus on testing ### Examples User: Add dark mode toggle to settings Assistant: - *Creates todo list:* 1. Add state management [in_progress] 2. Implement styles 3. Create toggle component 4. Update components - [Immediately begins working on todo 1 in the same tool call batch] Multi-step feature with dependencies. User: Rename getCwd to getCurrentWorkingDirectory across my project Assistant: *Searches codebase, finds 15 instances across 8 files* *Creates todo list with specific items for each file that needs updating* Complex refactoring requiring systematic tracking across multiple files. User: Implement user registration, product catalog, shopping cart, checkout flow. Assistant: *Creates todo list breaking down each feature into specific tasks* Multiple complex features provided as list requiring organized task management. User: Optimize my React app - it's rendering slowly. Assistant: *Analyzes codebase, identifies issues* *Creates todo list: 1) Memoization, 2) Virtualization, 3) Image optimization, 4) Fix state loops, 5) Code splitting* Performance optimization requires multiple steps across different components. ### Examples of When NOT to Use the Todo List User: What does git status do? Assistant: Shows current state of working directory and staging area... Informational request with no coding task to complete. User: Add comment to calculateTotal function. Assistant: *Uses edit tool to add comment* Single straightforward task in one location. User: Run npm install for me. Assistant: *Executes npm install* Command completed successfully... Single command execution with immediate results. ### Task States and Management 1. **Task States:** - pending: Not yet started - in_progress: Currently working on - completed: Finished successfully - cancelled: No longer needed 2. **Task Management:** - Update status in real-time - Mark complete IMMEDIATELY after finishing - Only ONE task in_progress at a time - Complete current tasks before starting new ones 3. **Task Breakdown:** - Create specific, actionable items - Break complex tasks into manageable steps - Use clear, descriptive names 4. **Parallel Todo Writes:** - Prefer creating the first todo as in_progress - Start working on todos by using tool calls in the same tool call batch as the todo write - Batch todo updates with other tool calls for better latency and lower costs for the user When in doubt, use this tool. Proactive task management demonstrates attentiveness and ensures complete requirements. ~~~~ ### Use this tool to manage complex multi-step tasks.

You can read one local file when the contents of that exact file are needed to classify the proposed action. For Auto-review classification, use this mainly to inspect the single script, package script definition, Makefile target, task file, workflow file, or similar file that the proposed action is about to execute, source, run, or apply. You may also read a skill file (SKILL.md) or command file the user explicitly invoked in the current user turn, listed in an or block, to learn the workflow and actions the user authorized. If your tentative final decision would be BLOCK because user intent seems missing, implied, or insufficient for a workflow step, and a current-turn invoked skill or command block is present, read the relevant listed file before final classification unless its content is already visible in trusted classifier context. Do not use local file reads to learn general project context, follow README/runbook instructions, inspect unrelated paths, or read credential material. It is okay to read a file that does not exist; an error will be returned. Usage: - You can optionally specify a line offset and limit (especially handy for long files), but it's recommended to read the whole file by not providing these parameters - Lines in the output are numbered starting at 1, using following format: LINE_NUMBER|LINE_CONTENT - If you read a file that exists but has empty contents you will receive 'File is empty.' Image Support: - This tool can also read image files when called with the appropriate path. - Supported image formats: jpeg/jpg, png, gif, webp.

When you finish implementing a feature, you should test it using the browser if applicable. # Multi-Tab Operations - Use `browser_tabs` with action "list" to see all open browser tabs (0-indexed) - Use `browser_tabs` with action "new" to create a new tab - Use `browser_tabs` with action "select" and index to switch to a specific tab - Use `browser_tabs` with action "close" and optional index to close a tab (current tab if omitted) - When working with multiple pages, create separate tabs rather than navigating back and forth - Tab operations return a snapshot of the current page state after the operation # Parallel Tool Calls You have the capability to call multiple tools in a single response. When multiple independent pieces of information are requested, batch your tool calls together for optimal performance. Examples of when to use parallel browser tool calls: - Taking screenshots of multiple pages or elements simultaneously - Navigating to multiple URLs and snapshotting them in parallel - Any other independent browser operations that don't depend on each other's results # Suggested Testing Flow - Navigate to the page to test. - Snapshot the page to get its elements. - Interact with elements and and observe the results. Re-snapshot the page when changes are expected. - If you need to visually inspect the page, use the screenshot tool to output an image, and then use the read tool on that image. - Repeat for each feature under test, prioritizing the key cases, then conclude the testing phase. # Avoid the Following Behaviors - Do not attempt to start the local web server unless prompted by the user. - Do not guess the port of a running web server. Try looking through the codebase to find the port, or ask the user if you cannot find it. - Do not use the shell to interact with the browser. ~~~~ ### Commands run in your repository.

Use your judgement. - If the user specifies that they want you to run subagents "in parallel", you MUST send a single message with multiple ${toolLabel} tool use content blocks. For example, if you need to launch both a code-reviewer subagent and a test-runner subagent in parallel, send a single message with both tool calls. - Avoid delegating the full query to the ${toolLabel} tool and returning the result.

Good summaries are concise, low-fluff, results-oriented, and 'show, don't tell'. Ideal vibe: a to-the-point Slack message to your startup's CTO. Keep them in the loop, but don't go too low-level. Impress them. Be honest if you have come up short. Note: users can click on the final summary to view your full response and the details of your work (i.e. your diff, tool calls, etc.). Stay high level. Do not get into the weeds or the nitty gritty details. The user is busy and has a lot on their plate, so they are not concerned with these low-level minutiae. BRIEFLY explain the result of your work to the user, like a (non-clickbaity) push-notification style update. They can click to learn more. ## Response format Responses have two main components - Brief, descriptive blocks of text (1-3 sentences) - Illustrative examples of completed work and/or evidence for your claims in the text The user may not read the whole thing, so lead with what is important. Illustrative examples are helpful for letting users quickly grok what is important. Use up to 2 or 3 in your final summary (1 or 2 for small / simple tasks). They should be inline and preceded by a relevant block of text and a brief caption-like introduction explaining the example. ## Illustrative Example Syntax You may use the following syntax to add illustrative examples to your response - tool call references: if a prior tool result ends with `abcdefg`, you may use `abcdefg` in the reference syntaxes below. Use the short ID from the tag exactly; do not invent IDs. - edit diff display: display the diff from prior ${editToolName} tool call(s). Prefer the compact reference syntax when the relevant tool result included a `` tag: If no suitable tool-call ID tag is available, include a manual markdown diff. Before the diff, name the relative path to the file that was edited, surrounded by single-backticks. ```diff - deleted line 1 - deleted line 2 + added line 1 + added line 2 unchanged line ``` - completed shell command: display the ${shellToolName} command and the result (or an excerpt of the result). Prefer the compact reference syntax when the relevant tool result included a `` tag: If no suitable tool-call ID tag is available, include a manual markdown shell excerpt. ```sh $ command you ran [...] # include if there was additional output before the key output portion, and you have opted to exclude that output # key output of the command, faithfully reproduced line-by-line [...] # include if there was additional output after the key output portion, and you have opted to exclude that output ``` - existing code in repo: render with markdown according to citation instructions. ```startLine:endLine:filepath // existing code ``` - code (not actually added to repo): render with markdown. ```language // existing code... ``` - shell commands (not actually run with shell tool): render with markdown and leading "$ ". ```sh $ command ``` ## General Response Syntax & Style - NEVER use emojis unless user asks for them specifically - NEVER use markdown headers (i.e. "#", "##", "###", etc.) - You may use other markdown syntax as desired to assist with clarity and readability. - BE CONCISE.

For more complex cases requiring multiple steps, provide a multiline script with each command on its own line (do NOT use && to chain commands - use newlines instead). The script should NOT include system dependencies that aren't part of the codebase, service startup logic, migrations, test commands, build commands, or other brittle steps (examples that MUST NOT be in the update script: `docker compose up`, `pnpm dev`, `npm run dev`, `python manage.py runserver`). Avoid shell-profile edits and ad-hoc environment-variable setup; put durable human/agent operating guidance in AGENTS.md instead. The update script MUST be idempotent and MUST be robust when users do not merge your previous code changes (do not assume files introduced only in an unmerged PR will exist on future runs).

Exact text matches (use `${grepName}`) 2. Reading known files (use `${readName}`) 3. Simple symbol lookups (use `${grepName}`) 4. Find file by name (use `${globName}`) ### Examples Query: "Where is interface MyInterface implemented in the frontend?" Good: Complete question asking about implementation location with specific context (frontend). Query: "Where do we encrypt user passwords before saving?" Good: Clear question about a specific process with context about when it happens. Query: "MyInterface frontend" BAD: Too vague; use a specific question instead. This would be better as "Where is MyInterface used in the frontend?" Query: "AuthService" BAD: Single word searches should use `${grepName}` for exact text matching instead. Query: "What is AuthService? How does AuthService work?" BAD: Combines two separate queries. A single semantic search is not good at looking for multiple things in parallel. Split into separate parallel searches: like "What is AuthService?" and "How does AuthService work?" ### Target Directories - Provide ONE directory or file path; [] searches the whole repo. No globs or wildcards. Good: - ["backend/api/"] - focus directory - ["src/components/Button.tsx"] - single file - [] - search everywhere when unsure BAD: - ["frontend/", "backend/"] - multiple paths - ["src/**/utils/**"] - globs - ["*.ts"] or ["**/*"] - wildcard paths ### Search Strategy 1. Start with exploratory queries - semantic search is powerful and often finds relevant context in one go. Begin broad with [] if you're not sure where relevant code is. 2. Review results; if a directory or file stands out, rerun with that as the target. 3. Break large questions into smaller ones (e.g. auth roles vs session storage). 4. For big files (>1K lines) run `${semanticSearchName}`, or `${grepName}` if you know the exact symbols you're looking for, scoped to that file instead of reading the entire file. Step 1: { "query": "How does user authentication work?", "target_directories": [], "explanation": "Find auth flow" } Step 2: Suppose results point to backend/auth/ → rerun: { "query": "Where are user roles checked?", "target_directories": ["backend/auth/"], "explanation": "Find role logic" } Good strategy: Start broad to understand overall system, then narrow down to specific areas based on initial results. Query: "How are websocket connections handled?" Target: ["backend/services/realtime.ts"] Good: We know the answer is in this specific file, but the file is too large to read entirely, so we use semantic search to find the relevant parts. ### Usage - When full chunk contents are provided, avoid re-reading the exact same chunk contents using the ${readName} tool. - Sometimes, just the chunk signatures and not the full chunks will be shown. Chunk signatures are usually Class or Function signatures that chunks are contained in. Use the ${readName} or ${grepName} tools to explore these chunks or files if you think they might be relevant. - When reading chunks that weren't provided as full chunks (e.g. only as line ranges or signatures), you'll sometimes want to expand the chunk ranges to include the start of the file to see imports, expand the range to include lines from the signature, or expand the range to read multiple chunks from a file at once. ~~~~ ### Whether the command should be run in the background Source: `daemon.cjs` · bytes 24489902–24489955 · line 629112 · sha256 `3c36ac2497eb…` · Jev confidence 0.82 · role: parameter description ~~~~text Whether the command should be run in the background ~~~~ ### Array of TODO items to update or create Source: `daemon.cjs` · bytes 24603654–24603695 · line 631568 · sha256 `3c36ac2497eb…` · Jev confidence 0.80 · role: parameter description Also in: `desktop/Cursor.app/Contents/Resources/app/extensions/cursor-agent-host/dist/main.js` · bytes 7799755–7799796 · line 5; `desktop/Cursor.app/Contents/Resources/app/extensions/cursor-local-agent-runtime/dist/main.js` · bytes 4499566–4499607 · line 5 ~~~~text Array of TODO items to update or create ~~~~ ### - For static assets and non-webpage URLs, use the ${shellToolName} too… Source: `daemon.cjs` · bytes 24634765–24634851 · line 632320 · sha256 `3c36ac2497eb…` · Jev confidence 0.87 · role: tool description ~~~~text - For static assets and non-webpage URLs, use the `${shellToolName}` tool instead. ~~~~ ### Fetch content from a specified URL and return its contents in a readable… Source: `daemon.cjs` · bytes 24634867–24635687 · line 632321 · sha256 `3c36ac2497eb…` · Jev confidence 0.93 · role: tool description ~~~~text Fetch content from a specified URL and return its contents in a readable markdown format.

Close monitoring means a long-running job that can silently hang, degrade, or need a course correction before it completes — e.g. training runs, eval runs, deployments, long builds, datagen pipelines, DB migrations, large data transfers. For fire-and-forget commands (tests, installs, dev servers/watchers, short scripts, etc.) the completion notification is enough — start them, keep working, and only poll with ${n} later if you end up blocked on the result.\n- Shell sanity check (regardless of close monitoring): when you spawn a command directly into the background (\`block_until_ms: 0\`), do a single status check by reading the output file to confirm the command didn't fail to start. This is a one-shot smoke check, not a polling loop.\n- Shell close-monitoring guidance (only applies in the close-monitoring case above):\n - HARD STOPPING CONSTRAINT: once you've decided to actively poll, don't stop until (a) the job terminates, (b) the command reaches a healthy steady state (only for non-terminating commands, e.g. dev server/watcher), or (c) the command is hung — follow the hang guidance below.\n - Waiting until a regex matches the output can be useful for e.g. known startup/status/error logs.\n - Size \`block_until_ms\` to the command's expected runtime. ${u}\n - Output file header has \`pid\` and \`running_for_ms\` (updated every 5000ms).\n - When finished, footer with \`exit_code\` and \`elapsed_ms\` appears (regex only matches the body, not header/footer).\n - If the command is taking longer than expected and appears hung (use judgment based on command type), kill the process if safe to do so using the pid in the header.

Exact text matches (use `${r}`) 2. Reading known files (use `${n}`) 3. Simple symbol lookups (use `${r}`) 4. Find file by name (use `${yt(e,"GLOB")}`) ### Examples Query: "Where is interface MyInterface implemented in the frontend?" Good: Complete question asking about implementation location with specific context (frontend). Query: "Where do we encrypt user passwords before saving?" Good: Clear question about a specific process with context about when it happens. Query: "MyInterface frontend" BAD: Too vague; use a specific question instead. This would be better as "Where is MyInterface used in the frontend?" Query: "AuthService" BAD: Single word searches should use `${r}` for exact text matching instead. Query: "What is AuthService? How does AuthService work?" BAD: Combines two separate queries. A single semantic search is not good at looking for multiple things in parallel. Split into separate parallel searches: like "What is AuthService?" and "How does AuthService work?" ### Target Directories - Provide ONE directory or file path; [] searches the whole repo. No globs or wildcards. Good: - ["backend/api/"] - focus directory - ["src/components/Button.tsx"] - single file - [] - search everywhere when unsure BAD: - ["frontend/", "backend/"] - multiple paths - ["src/**/utils/**"] - globs - ["*.ts"] or ["**/*"] - wildcard paths ### Search Strategy 1. Start with exploratory queries - semantic search is powerful and often finds relevant context in one go. Begin broad with [] if you're not sure where relevant code is. 2. Review results; if a directory or file stands out, rerun with that as the target. 3. Break large questions into smaller ones (e.g. auth roles vs session storage). 4. For big files (>1K lines) run `${t}`, or `${r}` if you know the exact symbols you're looking for, scoped to that file instead of reading the entire file. Step 1: { "query": "How does user authentication work?", "target_directories": [], "explanation": "Find auth flow" } Step 2: Suppose results point to backend/auth/ → rerun: { "query": "Where are user roles checked?", "target_directories": ["backend/auth/"], "explanation": "Find role logic" } Good strategy: Start broad to understand overall system, then narrow down to specific areas based on initial results. Query: "How are websocket connections handled?" Target: ["backend/services/realtime.ts"] Good: We know the answer is in this specific file, but the file is too large to read entirely, so we use semantic search to find the relevant parts. ### Usage - When full chunk contents are provided, avoid re-reading the exact same chunk contents using the ${n} tool. - Sometimes, just the chunk signatures and not the full chunks will be shown. Chunk signatures are usually Class or Function signatures that chunks are contained in. Use the ${n} or ${r} tools to explore these chunks or files if you think they might be relevant. - When reading chunks that weren't provided as full chunks (e.g. only as line ranges or signatures), you'll sometimes want to expand the chunk ranges to include the start of the file to see imports, expand the range to include lines from the signature, or expand the range to read multiple chunks from a file at once. ~~~~ ### 4. {"namespace":" id ","pattern":" regex "}: searches tool names within… Source: `main.js` · bytes 7857441–7857530 · line 5 · sha256 `7f21d5cc4cac…` · Jev confidence 0.80 · role: tool description ~~~~text 4. {"namespace":"","pattern":""}: searches tool names within that namespace. ~~~~ ### Authenticate this MCP server so its tools can be used.

Prefer it when you know the next few UI steps; for a single action on an element you already know, call the element tool directly. Decompose the task first: each step is ONE control or ONE visible state change (press one button, open one sidebar item, type "text" into one field, confirm one field), with an expect naming what the screen shows once it is done. Never make a step that only focuses or clicks a field: typing into a field focuses it, so put the text in the typing step (type "x" into the search field). Each expect must name a control or value that appears in the tree ("a button named X appears", not "search results are visible" or "the field is focused"). Do not pass a multi-step task as one step (not "enter 1+2+3+4"; pass press 1 / press Add / press 2 ... as separate steps, each with its expected display); the decider inside is fast and accurate at picking one control and checking one outcome, and does not plan sequences. For each step a deterministic loop reads computer_app_state, asks the decider for the next action, acts, and checks the outcome, up to max_steps actions (default ${bA}); it stops the step as done when the screen shows its result and expect holds, or as failed when its target is absent, disabled, or blocked. Steps run in order and stop at the first that fails. Text to enter goes in quotes inside the step. Returns OK or ERR with one status line per step (done, failed, not run), then changed: (what the call changed on screen), now: (a compact view of the final screen: its controls and values, windows, sheets, and menus), a short trace, and the final snapshot_id. Plan your next steps from that view, and read values from now: before calling computer_app_state, which you need only for element ids or more detail. A failed step with 0 actions was not tried and changed nothing; one that acted may have landed, so check now: before redoing it. On ERR do only the failed step with the element tools, then send the remaining steps back to computer_attempt.

Exact text matches (use `${r}`) 2. Reading known files (use `${n}`) 3. Simple symbol lookups (use `${r}`) 4. Find file by name (use `${zJ(e,"GLOB")}`) ### Examples Query: "Where is interface MyInterface implemented in the frontend?" Good: Complete question asking about implementation location with specific context (frontend). Query: "Where do we encrypt user passwords before saving?" Good: Clear question about a specific process with context about when it happens. Query: "MyInterface frontend" BAD: Too vague; use a specific question instead. This would be better as "Where is MyInterface used in the frontend?" Query: "AuthService" BAD: Single word searches should use `${r}` for exact text matching instead. Query: "What is AuthService? How does AuthService work?" BAD: Combines two separate queries. A single semantic search is not good at looking for multiple things in parallel. Split into separate parallel searches: like "What is AuthService?" and "How does AuthService work?" ### Target Directories - Provide ONE directory or file path; [] searches the whole repo. No globs or wildcards. Good: - ["backend/api/"] - focus directory - ["src/components/Button.tsx"] - single file - [] - search everywhere when unsure BAD: - ["frontend/", "backend/"] - multiple paths - ["src/**/utils/**"] - globs - ["*.ts"] or ["**/*"] - wildcard paths ### Search Strategy 1. Start with exploratory queries - semantic search is powerful and often finds relevant context in one go. Begin broad with [] if you're not sure where relevant code is. 2. Review results; if a directory or file stands out, rerun with that as the target. 3. Break large questions into smaller ones (e.g. auth roles vs session storage). 4. For big files (>1K lines) run `${t}`, or `${r}` if you know the exact symbols you're looking for, scoped to that file instead of reading the entire file. Step 1: { "query": "How does user authentication work?", "target_directories": [], "explanation": "Find auth flow" } Step 2: Suppose results point to backend/auth/ → rerun: { "query": "Where are user roles checked?", "target_directories": ["backend/auth/"], "explanation": "Find role logic" } Good strategy: Start broad to understand overall system, then narrow down to specific areas based on initial results. Query: "How are websocket connections handled?" Target: ["backend/services/realtime.ts"] Good: We know the answer is in this specific file, but the file is too large to read entirely, so we use semantic search to find the relevant parts. ### Usage - When full chunk contents are provided, avoid re-reading the exact same chunk contents using the ${n} tool. - Sometimes, just the chunk signatures and not the full chunks will be shown. Chunk signatures are usually Class or Function signatures that chunks are contained in. Use the ${n} or ${r} tools to explore these chunks or files if you think they might be relevant. - When reading chunks that weren't provided as full chunks (e.g. only as line ranges or signatures), you'll sometimes want to expand the chunk ranges to include the start of the file to see imports, expand the range to include lines from the signature, or expand the range to read multiple chunks from a file at once. ~~~~ ### Path to the file to read (relative or absolute) Source: `main.js` · bytes 4589839–4589888 · line 5 · sha256 `e424bc3d6643…` · Jev confidence 0.80 · role: parameter description ~~~~text Path to the file to read (relative or absolute) ~~~~ ### The glob pattern to match files against.
