Subject: [PATCH 01/12] fix: keep MCP structured results and warn on malformed
 model entries

Preserve an MCP tool's structured payload alongside its text and media
blocks, dropping the structured copy only when a text block already
carries the same complete JSON value, and escape angle brackets in the
serialized extras instead of stripping literal closing tags.

Warn at config load when a [models] entry has no model field, with a
hint when an unquoted dotted alias parsed as a nested table. Config
sections now contribute load-time diagnostics through a hook.

Scrub every ambient product env var in the engine and gateway test
setups and give the SDK, client and extension projects an explicit
integration-test timeout.

 [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) is an open protocol that lets models safely call tools exposed by external processes or services — for example, reading GitHub issues, querying databases, or operating the local file system. Pythinker Code CLI acts as an MCP client to connect these external tools and exposes them to the Agent alongside built-in tools (`Read`, `Bash`, `Grep`, etc.) with no behavioral difference.
 
+MCP tool results can include text (`content`) and structured data (`structuredContent`). Pythinker Code CLI makes both available to the agent and omits the structured copy only when it can confirm that a text block already contains the same complete JSON value. Text summaries and media do not replace structured records.
+
 ## Connection Methods
 
 Pythinker Code CLI supports three MCP server connection methods:

Subject: [PATCH 02/12] feat: allow read-only tools in side questions and
 clarify subagent models

Side questions started with /btw can now call Read, Grep and Glob so
answers can rest on current file contents; every write or execute tool
stays rejected.

The subagent model list now always names what "primary" is bound to,
drops the duplicate main-model marker, states that pool entries do not
inherit the caller's thinking level, and the dynamic-workflow tool
renders the pool as a one-line summary instead of repeating the block.

 hundred

Glob now takes offset and head_limit, defaults to 100 matches, and
accepts head_limit=0 to lift the match-count limit. Every page stays
within the output character limit, ends on a complete path, reports the
range it covers, and gives the next offset when more matches remain.
The tool card counts only paths, and marks a page that is not the last.

 **`Grep`** invokes ripgrep to search file contents, supporting regular expressions (`pattern`), a search path (`path`), file type filtering (`type`, e.g., `ts`, `py`), glob filtering (`glob`), and output mode (`output_mode`: `files_with_matches` / `content` / `count_matches`; defaults to `files_with_matches`). `content` mode supports context lines (`-A`, `-B`, `-C`), case-insensitive matching (`-i`), line numbers (`-n`, default true), and multiline matching (`multiline`). All modes support `offset` + `head_limit` pagination; `head_limit` defaults to 250 and `0` means unlimited. Sensitive files such as `.env` files and private keys are automatically filtered out; set `include_ignored=true` to search files ignored by `.gitignore`, though sensitive files remain filtered.
 
-**`Glob`** matches files in a specified directory (`path`; defaults to the working directory) by glob pattern (`pattern`). Results are sorted by modification time in descending order, with a maximum of 100 entries. It respects `.gitignore`, `.ignore`, and `.rgignore` by default; set `include_ignored=true` to include ignored files such as build outputs, while sensitive files remain filtered. Brace patterns such as `*.{ts,tsx}` are supported, and broad wildcard patterns are allowed but usually truncate at the match cap.

+Use `offset` (default 0) and `head_limit` (default 100) to page through matching paths; the result provides the next offset when more matches are available. Set `head_limit: 0` to remove the match-count limit. The character limit still applies: pages end at a complete path and provide the next offset when necessary. Large pages are saved to a file that the agent can read with `Read`. Each call searches the current filesystem again, so file changes can shift results between pages. Timeouts, unreadable directories, or the output capture limit can still leave the search incomplete; the result warns about these cases, and increasing the offset cannot recover uncollected paths.
 
 **`ReadMediaFile`** sends an image or video to the model as multimodal content. It accepts `path`, plus optional image-detail controls such as `region` and `full_resolution`; the file size limit is 100 MB. Default image reads are compressed to the configured model limits. If automatic compression cannot meet those limits safely, the tool returns an error without sending the original image and directs the model to create and read a smaller copy. Availability depends on the current model's vision capabilities (`image_in` / `video_in`).

-Results are capped at the first 100 matching paths. If a search would return more, a truncation marker is appended. Refine the pattern (extension, subdirectory) when 100 is not enough, or call again with a narrower anchor.
+Results default to 100 matching paths. Use `offset` (default 0) and `head_limit` (default 100) to page through results. When more matches are available, the result gives the next offset; keep the other search arguments unchanged. Set `head_limit=0` to remove the match-count limit.

+Each call searches the current filesystem again; pagination is not a snapshot, and file changes can shift results between pages. To collect a large list, use `head_limit=0`, read any saved output, and follow continuation offsets if the character limit is reached. Search timeouts, traversal errors, and output capture limits can still produce partial results; the result reports these limits, and pagination cannot recover paths that were never collected. Narrow the search and retry when it is incomplete.
 
 Large-directory caveat — avoid recursing into dependency / build output even with an anchor, especially when `include_ignored` is set:

The subagent runs as a same-process loop instance with its own context and wire file. Delegating also keeps the bulk of intermediate file contents out of your own context — you get a conclusion back instead of a pile of dumps.\\n\\nWriting the prompt:\\n- The subagent starts with zero context — it has not seen this conversation. Brief it like a colleague who just walked into the room: state the goal, list what you already know, hand over the specifics.\\n- Lookups (read this file, run that test): put the exact path or command in the prompt. The subagent should not have to search for things you already know.\\n- Investigations (figure out X, find why Y): give the question, not prescribed steps — fixed steps become dead weight when the premise is wrong.\\n- Do not delegate understanding. If the task hinges on a file path or line number, find it yourself first and write it into the prompt.\\n\\nUsage notes:\\n- When the task continues earlier work a subagent already did, prefer resuming that agent (pass its \`resume\` id) over spawning a fresh instance — the resumed agent keeps its prior context.\\n- A subagent's result is only visible to you, not to the user. When the user needs to see what a subagent produced, summarize the relevant parts yourself in your own reply.\\n- Subagents use a fixed 2-hour timeout. If one times out, resume the same agent instead of starting over.\\n\\nWhen NOT to use Agent: skip delegation for trivial work you can do directly — reading a file whose path you already know, searching a small known set of files, or any task that takes only a step or two. Delegation has a context-handoff cost; it pays off only when the task is substantial enough to outweigh it.\\n\\nOnce a subagent is running, leave that scope to it: do not redo its searches or reads in parallel, and do not abandon it midway and finish the job manually. Both undo the context savings the delegation was meant to buy.\\n\\n\\nWhen \`run_in_background=true\`, the subagent runs detached from this turn. The completion arrives in a later turn as a synthetic user-role message containing its result — you do not need to poll, sleep, or check on its progress. Continue with other work or respond to the user. Never fabricate or predict what the result will say.\\n\\nDefault to a foreground subagent (omit \`run_in_background\`) when your next step needs its result — foreground hands the result straight back. Reach for \`run_in_background=true\` only when you have other work to do while it runs and do not need its result to proceed. Never launch in the background and then immediately wait on it (by polling \`TaskOutput\`, sleeping, or otherwise): that just blocks the turn for no benefit — run it in the foreground instead.\\n\\n\\nAvailable agent types (pass via subagent_type):\\n- plan: Read-only implementation planning and architecture design. Use this agent when the parent agent needs a step-by-step implementation plan, key file identification, and architectural trade-off analysis before code changes are made.\\n  Tools: Read, ReadMediaFile, Glob, Grep, WebSearch, FetchURL\\n- coder: General software engineering agent — the only subagent type with file-editing tools; use it for any delegated task that must modify code. Use this agent for non-trivial software engineering work that may require reading files, editing code, running commands, and returning a compact but technically complete summary to the parent agent.\\n  Tools: Bash, CronCreate, CronDelete, CronList, Edit, EnterPlanMode, ExitPlanMode, Glob, Grep, Read, ReadMediaFile, Skill, TaskList, TaskOutput, TaskStop, TodoList, WaitFor, WebSearch, FetchURL, Write, mcp__*\\n- explore: Fast codebase exploration with prompt-enforced read-only behavior. Fast agent specialized for exploring codebases. Use this when you need to quickly find files by patterns (e.g. \\"src/**/*.yaml\\"), search code for keywords (e.g. \\"database connection\\"), or answer questions about the codebase (e.g. \\"how does the auth module work?\\"). When calling this agent, specify the desired thoroughness level: \\"quick\\" for basic searches, \\"medium\\" for moderate exploration, or \\"thorough\\" for comprehensive analysis across multiple locations and naming conventions. Use this agent for any read-only exploration that will clearly require more than 3 search queries.

When doing that, you must provide a short \`description\`. Background commands default to a 600s timeout and \`timeout\` is capped at 86400s; set \`disable_timeout=true\` only when the task should run without a timeout. You will be automatically notified when the task completes. After starting one, default to returning control to the user instead of immediately waiting on it. Use \`TaskOutput\` only for a non-blocking status/output snapshot — do not wait on a task you just launched, since its completion arrives automatically. Use \`TaskStop\` only if the task must be cancelled. If a human user wants to inspect background tasks themselves, point them to the background-task panel.\\n\\n**Guidelines for safety and security:**\\n- Each shell tool call will be executed in a fresh shell environment. The shell variables, current working directory changes, and the shell history is not preserved between calls. To run a command in a particular directory, pass the \`cwd\` argument (or use absolute paths) rather than relying on a \`cd\` from an earlier call.\\n- The tool call will return after the command is finished. You shall not use this tool to execute an interactive command or a command that may run forever. For possibly long-running foreground commands, set the \`timeout\` argument in seconds. Foreground commands default to 60s and allow up to 300s. When a foreground command hits its timeout it is moved to the background instead of being killed, and you will be automatically notified when it completes. The user can also move a running foreground command to the background at any time.\\n- Avoid using \`..\` to access files or directories outside of the working directory.\\n- Avoid modifying files outside of the working directory unless explicitly instructed to do so.\\n- Never run commands that require superuser privileges unless explicitly instructed to do so.\\n- Run git-mutating commands such as \`git commit\`, \`git push\`, \`git reset\`, and \`git rebase\` only when the user asks for them.\\n\\n**Guidelines for efficiency:**\\n- Use \`&&\` to chain commands that genuinely depend on each other, e.g. \`npm install && npm test\`. Independent read-only commands (separate \`git show\`, \`ls\`, or status checks) should be issued as separate parallel Bash calls in one response, not chained into a single call — chaining serializes their execution and mixes their output. Do not stitch outputs together with \`echo\` separators.\\n- Use \`;\` to run commands sequentially regardless of success/failure\\n- Use \`||\` for conditional execution (run second command only if first fails)\\n- Use pipe operations (\`|\`) and redirections (\`>\`, \`>>\`) to chain input and output between commands\\n- Always quote file paths containing spaces with double quotes (e.g., cd \\"/path with spaces/\\")\\n- Compose multi-step logic in a single call with \`if\` / \`case\` / \`for\` / \`while\` control flows.\\n- Prefer \`run_in_background=true\` for long-running builds, tests, watchers, or servers when you need the conversation to continue before the command finishes.\\n\\n**Commands available:**\\nThe following common command categories are usually available. Availability still depends on the host, so when in doubt run \`which <command>\` first to confirm a command exists before relying on it.\\n- Navigation and inspection: \`ls\`, \`pwd\`, \`cd\`, \`stat\`, \`file\`, \`du\`, \`df\`, \`tree\`\\n- File and directory management: \`cp\`, \`mv\`, \`rm\`, \`mkdir\`, \`touch\`, \`ln\`, \`chmod\`, \`chown\`\\n- Text and data processing: \`wc\`, \`sort\`, \`uniq\`, \`cut\`, \`tr\`, \`diff\`, \`xargs\`\\n- Archives and compression: \`tar\`, \`gzip\`, \`gunzip\`, \`zip\`, \`unzip\`\\n- Networking and transfer: \`curl\`, \`wget\`, \`ping\`, \`ssh\`, \`scp\`\\n- Version control: \`git\`; for GitHub-hosted work (PRs, issues, CI runs, API queries) prefer the \`gh\` CLI when installed — it carries the user's GitHub auth and can return structured JSON\\n- Process and system: \`ps\`, \`kill\`, \`top\`, \`env\`, \`date\`, \`uname\`, \`whoami\`\\n- Language and package toolchains: \`node\`, \`npm\`, \`pnpm\`, \`yarn\`, \`python\`, \`pip\` (use whichever the project actually relies on)\\n", "parameters": { "$schema": "http://json-schema.org/draft-07/schema#", "type": "object", "properties": { "command": { "type": "string", "minLength": 1, "description": "The command to execute." }, "cwd": { "description": "The working directory in which to run the command.

One-shot tasks are never marked stale.\\n\\n## Jitter behavior\\n\\nAnti-herd jitter is applied deterministically per task id:\\n  - Recurring: ideal fire time is shifted **forward** by an offset ≤ min(10% of the cron period, 15 minutes). A \`*/5 * * * *\` task can drift up to 30s; a \`0 9 * * *\` task can drift up to 15 minutes.\\n  - One-shot: only when the ideal fire lands on \`:00\` or \`:30\` of the hour, the fire is pulled **earlier** by ≤ 90 seconds. Other minutes pass through unchanged.\\n\\n## One-shot vs recurring — when to pick which\\n\\nUse \`recurring: false\` for \\"remind me at X\\" style requests, single deadlines, \\"in N minutes do Y\\", and any task that should not repeat. Use \`recurring: true\` for periodic polling (CI status, build watchers, scheduled reports), workday rituals, and anything the user explicitly described as recurring.\\n\\n## Session lifetime\\n\\nCron tasks live in the current session. When you exit, they\\nare persisted under the session homedir; resuming the same session\\nreloads them and the scheduler resumes from each task's \`createdAt\`. Fire times that fell during the offline window are\\ncollapsed into a single delivery via \`coalescedCount\` (and recurring\\ntasks past their 7-day window arrive with \`stale: true\` as their final\\ndelivery).\\n\\nTasks do **not** carry over into a brand-new session — they are scoped\\nto the resumed session id, not to the working directory.\\n\\n## Limits\\n\\nA session holds at most 50 live cron tasks; creating one beyond that is rejected.

The subagent runs as a same-process loop instance with its own context and wire file. Delegating also keeps the bulk of intermediate file contents out of your own context — you get a conclusion back instead of a pile of dumps.\\n\\nWriting the prompt:\\n- The subagent starts with zero context — it has not seen this conversation. Brief it like a colleague who just walked into the room: state the goal, list what you already know, hand over the specifics.\\n- Lookups (read this file, run that test): put the exact path or command in the prompt. The subagent should not have to search for things you already know.\\n- Investigations (figure out X, find why Y): give the question, not prescribed steps — fixed steps become dead weight when the premise is wrong.\\n- Do not delegate understanding. If the task hinges on a file path or line number, find it yourself first and write it into the prompt.\\n\\nUsage notes:\\n- When the task continues earlier work a subagent already did, prefer resuming that agent (pass its \`resume\` id) over spawning a fresh instance — the resumed agent keeps its prior context.\\n- A subagent's result is only visible to you, not to the user. When the user needs to see what a subagent produced, summarize the relevant parts yourself in your own reply.\\n- Subagents use a fixed 2-hour timeout. If one times out, resume the same agent instead of starting over.\\n\\nWhen NOT to use Agent: skip delegation for trivial work you can do directly — reading a file whose path you already know, searching a small known set of files, or any task that takes only a step or two. Delegation has a context-handoff cost; it pays off only when the task is substantial enough to outweigh it.\\n\\nOnce a subagent is running, leave that scope to it: do not redo its searches or reads in parallel, and do not abandon it midway and finish the job manually. Both undo the context savings the delegation was meant to buy.\\n\\n\\nWhen \`run_in_background=true\`, the subagent runs detached from this turn. The completion arrives in a later turn as a synthetic user-role message containing its result — you do not need to poll, sleep, or check on its progress. Continue with other work or respond to the user. Never fabricate or predict what the result will say.\\n\\nDefault to a foreground subagent (omit \`run_in_background\`) when your next step needs its result — foreground hands the result straight back. Reach for \`run_in_background=true\` only when you have other work to do while it runs and do not need its result to proceed.

Use this agent when the parent agent needs a step-by-step implementation plan, key file identification, and architectural trade-off analysis before code changes are made.\\n  Tools: Read, ReadMediaFile, Glob, Grep, WebSearch, FetchURL\\n- coder: General software engineering agent — the only subagent type with file-editing tools; use it for any delegated task that must modify code. Use this agent for non-trivial software engineering work that may require reading files, editing code, running commands, and returning a compact but technically complete summary to the parent agent.\\n  Tools: Bash, CronCreate, CronDelete, CronList, Edit, EnterPlanMode, ExitPlanMode, Glob, Grep, Read, ReadMediaFile, Skill, TaskList, TaskOutput, TaskStop, TodoList, WaitFor, WebSearch, FetchURL, Write, mcp__*\\n- explore: Fast codebase exploration with prompt-enforced read-only behavior. Fast agent specialized for exploring codebases.

Background commands default to a 600s timeout and \`timeout\` is capped at 86400s; set \`disable_timeout=true\` only when the task should run without a timeout. You will be automatically notified when the task completes. After starting one, default to returning control to the user instead of immediately waiting on it.

The shell variables, current working directory changes, and the shell history is not preserved between calls. To run a command in a particular directory, pass the \`cwd\` argument (or use absolute paths) rather than relying on a \`cd\` from an earlier call.\\n- The tool call will return after the command is finished. You shall not use this tool to execute an interactive command or a command that may run forever. For possibly long-running foreground commands, set the \`timeout\` argument in seconds. Foreground commands default to 60s and allow up to 300s. When a foreground command hits its timeout it is moved to the background instead of being killed, and you will be automatically notified when it completes. The user can also move a running foreground command to the background at any time.\\n- Avoid using \`..\` to access files or directories outside of the working directory.\\n- Avoid modifying files outside of the working directory unless explicitly instructed to do so.\\n- Never run commands that require superuser privileges unless explicitly instructed to do so.\\n- Run git-mutating commands such as \`git commit\`, \`git push\`, \`git reset\`, and \`git rebase\` only when the user asks for them.\\n\\n**Guidelines for efficiency:**\\n- Use \`&&\` to chain commands that genuinely depend on each other, e.g. \`npm install && npm test\`. Independent read-only commands (separate \`git show\`, \`ls\`, or status checks) should be issued as separate parallel Bash calls in one response, not chained into a single call — chaining serializes their execution and mixes their output. Do not stitch outputs together with \`echo\` separators.\\n- Use \`;\` to run commands sequentially regardless of success/failure\\n- Use \`||\` for conditional execution (run second command only if first fails)\\n- Use pipe operations (\`|\`) and redirections (\`>\`, \`>>\`) to chain input and output between commands\\n- Always quote file paths containing spaces with double quotes (e.g., cd \\"/path with spaces/\\")\\n- Compose multi-step logic in a single call with \`if\` / \`case\` / \`for\` / \`while\` control flows.\\n- Prefer \`run_in_background=true\` for long-running builds, tests, watchers, or servers when you need the conversation to continue before the command finishes.\\n\\n**Commands available:**\\nThe following common command categories are usually available. Availability still depends on the host, so when in doubt run \`which <command>\` first to confirm a command exists before relying on it.\\n- Navigation and inspection: \`ls\`, \`pwd\`, \`cd\`, \`stat\`, \`file\`, \`du\`, \`df\`, \`tree\`\\n- File and directory management: \`cp\`, \`mv\`, \`rm\`, \`mkdir\`, \`touch\`, \`ln\`, \`chmod\`, \`chown\`\\n- Text and data processing: \`wc\`, \`sort\`, \`uniq\`, \`cut\`, \`tr\`, \`diff\`, \`xargs\`\\n- Archives and compression: \`tar\`, \`gzip\`, \`gunzip\`, \`zip\`, \`unzip\`\\n- Networking and transfer: \`curl\`, \`wget\`, \`ping\`, \`ssh\`, \`scp\`\\n- Version control: \`git\`; for GitHub-hosted work (PRs, issues, CI runs, API queries) prefer the \`gh\` CLI when installed — it carries the user's GitHub auth and can return structured JSON\\n- Process and system: \`ps\`, \`kill\`, \`top\`, \`env\`, \`date\`, \`uname\`, \`whoami\`\\n- Language and package toolchains: \`node\`, \`npm\`, \`pnpm\`, \`yarn\`, \`python\`, \`pip\` (use whichever the project actually relies on)\\n", "parameters": { "$schema": "http://json-schema.org/draft-07/schema#", "type": "object", "properties": { "command": { "type": "string", "minLength": 1, "description": "The command to execute." }, "cwd": { "description": "The working directory in which to run the command.

The origin carries \`coalescedCount\` showing how many ideal fires were collapsed into this single delivery. You should treat \`coalescedCount > 1\` as \\"I missed some checks; only the latest state matters\\" rather than running the prompt that many times.\\n\\n## Cron-fire envelope\\n\\nWhen a cron task fires, the prompt you scheduled is re-injected wrapped in an XML envelope that exposes the fire context:\\n\\n\`\`\`\\n<cron-fire jobId=\\"...\\" cron=\\"...\\" recurring=\\"true|false\\" coalescedCount=\\"N\\" stale=\\"true|false\\">\\n<prompt>\\nyour original prompt text, verbatim\\n</prompt>\\n</cron-fire>\\n\`\`\`\\n\\nThe envelope is parseable. Use \`coalescedCount > 1\` to know multiple ideal fires were collapsed into a single delivery (treat as \\"only the latest state matters\\"), and \`stale=\\"true\\"\` as a cue that the task is past its 7-day threshold.\\n\\n## 7-day stale behavior\\n\\nRecurring tasks that have been alive for more than 7 days fire one\\nfinal time with \`stale: true\` on the envelope, and the system then\\nauto-deletes the task. The flag is the model's notice that this is\\nthe last delivery. If the schedule is still wanted, call \`CronCreate\`\\nagain with the same \`cron\` and \`prompt\` — that resets \`createdAt\` and\\nstarts a fresh 7-day window. One-shot tasks are never marked stale.\\n\\n## Jitter behavior\\n\\nAnti-herd jitter is applied deterministically per task id:\\n  - Recurring: ideal fire time is shifted **forward** by an offset ≤ min(10% of the cron period, 15 minutes). A \`*/5 * * * *\` task can drift up to 30s; a \`0 9 * * *\` task can drift up to 15 minutes.\\n  - One-shot: only when the ideal fire lands on \`:00\` or \`:30\` of the hour, the fire is pulled **earlier** by ≤ 90 seconds. Other minutes pass through unchanged.\\n\\n## One-shot vs recurring — when to pick which\\n\\nUse \`recurring: false\` for \\"remind me at X\\" style requests, single deadlines, \\"in N minutes do Y\\", and any task that should not repeat. Use \`recurring: true\` for periodic polling (CI status, build watchers, scheduled reports), workday rituals, and anything the user explicitly described as recurring.\\n\\n## Session lifetime\\n\\nCron tasks live in the current session. When you exit, they\\nare persisted under the session homedir; resuming the same session\\nreloads them and the scheduler resumes from each task's \`createdAt\`. Fire times that fell during the offline window are\\ncollapsed into a single delivery via \`coalescedCount\` (and recurring\\ntasks past their 7-day window arrive with \`stale: true\` as their final\\ndelivery).\\n\\nTasks do **not** carry over into a brand-new session — they are scoped\\nto the resumed session id, not to the working directory.\\n\\n## Limits\\n\\nA session holds at most 50 live cron tasks; creating one beyond that is rejected.

The subagent runs as a same-process loop instance with its own context and wire file. Delegating also keeps the bulk of intermediate file contents out of your own context — you get a conclusion back instead of a pile of dumps.\\n\\nWriting the prompt:\\n- The subagent starts with zero context — it has not seen this conversation. Brief it like a colleague who just walked into the room: state the goal, list what you already know, hand over the specifics.\\n- Lookups (read this file, run that test): put the exact path or command in the prompt. The subagent should not have to search for things you already know.\\n- Investigations (figure out X, find why Y): give the question, not prescribed steps — fixed steps become dead weight when the premise is wrong.\\n- Do not delegate understanding. If the task hinges on a file path or line number, find it yourself first and write it into the prompt.\\n\\nUsage notes:\\n- When the task continues earlier work a subagent already did, prefer resuming that agent (pass its \`resume\` id) over spawning a fresh instance — the resumed agent keeps its prior context.\\n- A subagent's result is only visible to you, not to the user. When the user needs to see what a subagent produced, summarize the relevant parts yourself in your own reply.\\n- Subagents use a fixed 2-hour timeout. If one times out, resume the same agent instead of starting over.\\n\\nWhen NOT to use Agent: skip delegation for trivial work you can do directly — reading a file whose path you already know, searching a small known set of files, or any task that takes only a step or two. Delegation has a context-handoff cost; it pays off only when the task is substantial enough to outweigh it.\\n\\nOnce a subagent is running, leave that scope to it: do not redo its searches or reads in parallel, and do not abandon it midway and finish the job manually. Both undo the context savings the delegation was meant to buy.\\n\\n\\nWhen \`run_in_background=true\`, the subagent runs detached from this turn. The completion arrives in a later turn as a synthetic user-role message containing its result — you do not need to poll, sleep, or check on its progress. Continue with other work or respond to the user. Never fabricate or predict what the result will say.\\n\\nDefault to a foreground subagent (omit \`run_in_background\`) when your next step needs its result — foreground hands the result straight back. Reach for \`run_in_background=true\` only when you have other work to do while it runs and do not need its result to proceed. Never launch in the background and then immediately wait on it (by polling \`TaskOutput\`, sleeping, or otherwise): that just blocks the turn for no benefit — run it in the foreground instead.\\n\\n\\nAvailable agent types (pass via subagent_type):\\n- plan: Read-only implementation planning and architecture design. Use this agent when the parent agent needs a step-by-step implementation plan, key file identification, and architectural trade-off analysis before code changes are made.\\n  Tools: Read, ReadMediaFile, Glob, Grep, WebSearch, FetchURL\\n- coder: General software engineering agent — the only subagent type with file-editing tools; use it for any delegated task that must modify code. Use this agent for non-trivial software engineering work that may require reading files, editing code, running commands, and returning a compact but technically complete summary to the parent agent.\\n  Tools: Bash, CronCreate, CronDelete, CronList, Edit, EnterPlanMode, ExitPlanMode, Glob, Grep, Read, ReadMediaFile, Skill, TaskList, TaskOutput, TaskStop, TodoList, WaitFor, WebSearch, FetchURL, Write, mcp__*\\n- explore: Fast codebase exploration with prompt-enforced read-only behavior. Fast agent specialized for exploring codebases. Use this when you need to quickly find files by patterns (e.g. \\"src/**/*.yaml\\"), search code for keywords (e.g. \\"database connection\\"), or answer questions about the codebase (e.g. \\"how does the auth module work?\\"). When calling this agent, specify the desired thoroughness level: \\"quick\\" for basic searches, \\"medium\\" for moderate exploration, or \\"thorough\\" for comprehensive analysis across multiple locations and naming conventions.

The output may be truncated if it is too long. If the command exits non-zero, the output ends with a \`Command failed with exit code: N\` line; a command killed by its timeout or interrupted by the user ends with its own message instead.\\n\\nIf \`run_in_background=true\`, the command will be started as a background task and this tool will return a task ID instead of waiting for command completion. When doing that, you must provide a short \`description\`. Background commands default to a 600s timeout and \`timeout\` is capped at 86400s; set \`disable_timeout=true\` only when the task should run without a timeout. You will be automatically notified when the task completes. After starting one, default to returning control to the user instead of immediately waiting on it. Use \`TaskOutput\` only for a non-blocking status/output snapshot — do not wait on a task you just launched, since its completion arrives automatically. Use \`TaskStop\` only if the task must be cancelled. If a human user wants to inspect background tasks themselves, point them to the background-task panel.\\n\\n**Guidelines for safety and security:**\\n- Each shell tool call will be executed in a fresh shell environment. The shell variables, current working directory changes, and the shell history is not preserved between calls. To run a command in a particular directory, pass the \`cwd\` argument (or use absolute paths) rather than relying on a \`cd\` from an earlier call.\\n- The tool call will return after the command is finished. You shall not use this tool to execute an interactive command or a command that may run forever. For possibly long-running foreground commands, set the \`timeout\` argument in seconds. Foreground commands default to 60s and allow up to 300s. When a foreground command hits its timeout it is moved to the background instead of being killed, and you will be automatically notified when it completes. The user can also move a running foreground command to the background at any time.\\n- Avoid using \`..\` to access files or directories outside of the working directory.\\n- Avoid modifying files outside of the working directory unless explicitly instructed to do so.\\n- Never run commands that require superuser privileges unless explicitly instructed to do so.\\n- Run git-mutating commands such as \`git commit\`, \`git push\`, \`git reset\`, and \`git rebase\` only when the user asks for them.\\n\\n**Guidelines for efficiency:**\\n- Use \`&&\` to chain commands that genuinely depend on each other, e.g. \`npm install && npm test\`.

The origin carries \`coalescedCount\` showing how many ideal fires were collapsed into this single delivery. You should treat \`coalescedCount > 1\` as \\"I missed some checks; only the latest state matters\\" rather than running the prompt that many times.\\n\\n## Cron-fire envelope\\n\\nWhen a cron task fires, the prompt you scheduled is re-injected wrapped in an XML envelope that exposes the fire context:\\n\\n\`\`\`\\n<cron-fire jobId=\\"...\\" cron=\\"...\\" recurring=\\"true|false\\" coalescedCount=\\"N\\" stale=\\"true|false\\">\\n<prompt>\\nyour original prompt text, verbatim\\n</prompt>\\n</cron-fire>\\n\`\`\`\\n\\nThe envelope is parseable. Use \`coalescedCount > 1\` to know multiple ideal fires were collapsed into a single delivery (treat as \\"only the latest state matters\\"), and \`stale=\\"true\\"\` as a cue that the task is past its 7-day threshold.\\n\\n## 7-day stale behavior\\n\\nRecurring tasks that have been alive for more than 7 days fire one\\nfinal time with \`stale: true\` on the envelope, and the system then\\nauto-deletes the task. The flag is the model's notice that this is\\nthe last delivery. If the schedule is still wanted, call \`CronCreate\`\\nagain with the same \`cron\` and \`prompt\` — that resets \`createdAt\` and\\nstarts a fresh 7-day window. One-shot tasks are never marked stale.\\n\\n## Jitter behavior\\n\\nAnti-herd jitter is applied deterministically per task id:\\n  - Recurring: ideal fire time is shifted **forward** by an offset ≤ min(10% of the cron period, 15 minutes). A \`*/5 * * * *\` task can drift up to 30s; a \`0 9 * * *\` task can drift up to 15 minutes.\\n  - One-shot: only when the ideal fire lands on \`:00\` or \`:30\` of the hour, the fire is pulled **earlier** by ≤ 90 seconds. Other minutes pass through unchanged.\\n\\n## One-shot vs recurring — when to pick which\\n\\nUse \`recurring: false\` for \\"remind me at X\\" style requests, single deadlines, \\"in N minutes do Y\\", and any task that should not repeat. Use \`recurring: true\` for periodic polling (CI status, build watchers, scheduled reports), workday rituals, and anything the user explicitly described as recurring.\\n\\n## Session lifetime\\n\\nCron tasks live in the current session. When you exit, they\\nare persisted under the session homedir; resuming the same session\\nreloads them and the scheduler resumes from each task's \`createdAt\`. Fire times that fell during the offline window are\\ncollapsed into a single delivery via \`coalescedCount\` (and recurring\\ntasks past their 7-day window arrive with \`stale: true\` as their final\\ndelivery).\\n\\nTasks do **not** carry over into a brand-new session — they are scoped\\nto the resumed session id, not to the working directory.\\n\\n## Limits\\n\\nA session holds at most 50 live cron tasks; creating one beyond that is rejected.

Users have no direct \`/cron\` command or self-service UI to manage reminders themselves; they must ask the model to make changes (e.g. \\"cancel my 9am reminder\\" or \\"change my daily check to 10am\\").

The subagent runs as a same-process loop instance with its own context and wire file. Delegating also keeps the bulk of intermediate file contents out of your own context — you get a conclusion back instead of a pile of dumps.\\n\\nWriting the prompt:\\n- The subagent starts with zero context — it has not seen this conversation. Brief it like a colleague who just walked into the room: state the goal, list what you already know, hand over the specifics.\\n- Lookups (read this file, run that test): put the exact path or command in the prompt. The subagent should not have to search for things you already know.\\n- Investigations (figure out X, find why Y): give the question, not prescribed steps — fixed steps become dead weight when the premise is wrong.\\n- Do not delegate understanding. If the task hinges on a file path or line number, find it yourself first and write it into the prompt.\\n\\nUsage notes:\\n- When the task continues earlier work a subagent already did, prefer resuming that agent (pass its \`resume\` id) over spawning a fresh instance — the resumed agent keeps its prior context.\\n- A subagent's result is only visible to you, not to the user. When the user needs to see what a subagent produced, summarize the relevant parts yourself in your own reply.\\n- Subagents use a fixed 2-hour timeout. If one times out, resume the same agent instead of starting over.\\n\\nWhen NOT to use Agent: skip delegation for trivial work you can do directly — reading a file whose path you already know, searching a small known set of files, or any task that takes only a step or two. Delegation has a context-handoff cost; it pays off only when the task is substantial enough to outweigh it.\\n\\nOnce a subagent is running, leave that scope to it: do not redo its searches or reads in parallel, and do not abandon it midway and finish the job manually. Both undo the context savings the delegation was meant to buy.\\n\\n\\nWhen \`run_in_background=true\`, the subagent runs detached from this turn. The completion arrives in a later turn as a synthetic user-role message containing its result — you do not need to poll, sleep, or check on its progress.

Use this agent when the parent agent needs a step-by-step implementation plan, key file identification, and architectural trade-off analysis before code changes are made.\\n  Tools: Read, ReadMediaFile, Glob, Grep, WebSearch, FetchURL\\n- coder: General software engineering agent — the only subagent type with file-editing tools; use it for any delegated task that must modify code. Use this agent for non-trivial software engineering work that may require reading files, editing code, running commands, and returning a compact but technically complete summary to the parent agent.\\n  Tools: Bash, CronCreate, CronDelete, CronList, Edit, EnterPlanMode, ExitPlanMode, Glob, Grep, Read, ReadMediaFile, Skill, TaskList, TaskOutput, TaskStop, TodoList, WaitFor, WebSearch, FetchURL, Write, mcp__*\\n- explore: Fast codebase exploration with prompt-enforced read-only behavior. Fast agent specialized for exploring codebases. Use this when you need to quickly find files by patterns (e.g. \\"src/**/*.yaml\\"), search code for keywords (e.g. \\"database connection\\"), or answer questions about the codebase (e.g. \\"how does the auth module work?\\"). When calling this agent, specify the desired thoroughness level: \\"quick\\" for basic searches, \\"medium\\" for moderate exploration, or \\"thorough\\" for comprehensive analysis across multiple locations and naming conventions. Use this agent for any read-only exploration that will clearly require more than 3 search queries.

When doing that, you must provide a short \`description\`. Background commands default to a 600s timeout and \`timeout\` is capped at 86400s; set \`disable_timeout=true\` only when the task should run without a timeout. You will be automatically notified when the task completes. After starting one, default to returning control to the user instead of immediately waiting on it. Use \`TaskOutput\` only for a non-blocking status/output snapshot — do not wait on a task you just launched, since its completion arrives automatically. Use \`TaskStop\` only if the task must be cancelled. If a human user wants to inspect background tasks themselves, point them to the background-task panel.\\n\\n**Guidelines for safety and security:**\\n- Each shell tool call will be executed in a fresh shell environment. The shell variables, current working directory changes, and the shell history is not preserved between calls. To run a command in a particular directory, pass the \`cwd\` argument (or use absolute paths) rather than relying on a \`cd\` from an earlier call.\\n- The tool call will return after the command is finished. You shall not use this tool to execute an interactive command or a command that may run forever. For possibly long-running foreground commands, set the \`timeout\` argument in seconds. Foreground commands default to 60s and allow up to 300s. When a foreground command hits its timeout it is moved to the background instead of being killed, and you will be automatically notified when it completes. The user can also move a running foreground command to the background at any time.\\n- Avoid using \`..\` to access files or directories outside of the working directory.\\n- Avoid modifying files outside of the working directory unless explicitly instructed to do so.\\n- Never run commands that require superuser privileges unless explicitly instructed to do so.\\n- Run git-mutating commands such as \`git commit\`, \`git push\`, \`git reset\`, and \`git rebase\` only when the user asks for them.\\n\\n**Guidelines for efficiency:**\\n- Use \`&&\` to chain commands that genuinely depend on each other, e.g. \`npm install && npm test\`. Independent read-only commands (separate \`git show\`, \`ls\`, or status checks) should be issued as separate parallel Bash calls in one response, not chained into a single call — chaining serializes their execution and mixes their output. Do not stitch outputs together with \`echo\` separators.\\n- Use \`;\` to run commands sequentially regardless of success/failure\\n- Use \`||\` for conditional execution (run second command only if first fails)\\n- Use pipe operations (\`|\`) and redirections (\`>\`, \`>>\`) to chain input and output between commands\\n- Always quote file paths containing spaces with double quotes (e.g., cd \\"/path with spaces/\\")\\n- Compose multi-step logic in a single call with \`if\` / \`case\` / \`for\` / \`while\` control flows.\\n- Prefer \`run_in_background=true\` for long-running builds, tests, watchers, or servers when you need the conversation to continue before the command finishes.\\n\\n**Commands available:**\\nThe following common command categories are usually available. Availability still depends on the host, so when in doubt run \`which <command>\` first to confirm a command exists before relying on it.\\n- Navigation and inspection: \`ls\`, \`pwd\`, \`cd\`, \`stat\`, \`file\`, \`du\`, \`df\`, \`tree\`\\n- File and directory management: \`cp\`, \`mv\`, \`rm\`, \`mkdir\`, \`touch\`, \`ln\`, \`chmod\`, \`chown\`\\n- Text and data processing: \`wc\`, \`sort\`, \`uniq\`, \`cut\`, \`tr\`, \`diff\`, \`xargs\`\\n- Archives and compression: \`tar\`, \`gzip\`, \`gunzip\`, \`zip\`, \`unzip\`\\n- Networking and transfer: \`curl\`, \`wget\`, \`ping\`, \`ssh\`, \`scp\`\\n- Version control: \`git\`; for GitHub-hosted work (PRs, issues, CI runs, API queries) prefer the \`gh\` CLI when installed — it carries the user's GitHub auth and can return structured JSON\\n- Process and system: \`ps\`, \`kill\`, \`top\`, \`env\`, \`date\`, \`uname\`, \`whoami\`\\n- Language and package toolchains: \`node\`, \`npm\`, \`pnpm\`, \`yarn\`, \`python\`, \`pip\` (use whichever the project actually relies on)\\n", "parameters": { "$schema": "http://json-schema.org/draft-07/schema#", "type": "object", "properties": { "command": { "type": "string", "minLength": 1, "description": "The command to execute." }, "cwd": { "description": "The working directory in which to run the command.

One-shot tasks are never marked stale.\\n\\n## Jitter behavior\\n\\nAnti-herd jitter is applied deterministically per task id:\\n  - Recurring: ideal fire time is shifted **forward** by an offset ≤ min(10% of the cron period, 15 minutes). A \`*/5 * * * *\` task can drift up to 30s; a \`0 9 * * *\` task can drift up to 15 minutes.\\n  - One-shot: only when the ideal fire lands on \`:00\` or \`:30\` of the hour, the fire is pulled **earlier** by ≤ 90 seconds. Other minutes pass through unchanged.\\n\\n## One-shot vs recurring — when to pick which\\n\\nUse \`recurring: false\` for \\"remind me at X\\" style requests, single deadlines, \\"in N minutes do Y\\", and any task that should not repeat. Use \`recurring: true\` for periodic polling (CI status, build watchers, scheduled reports), workday rituals, and anything the user explicitly described as recurring.\\n\\n## Session lifetime\\n\\nCron tasks live in the current session. When you exit, they\\nare persisted under the session homedir; resuming the same session\\nreloads them and the scheduler resumes from each task's \`createdAt\`. Fire times that fell during the offline window are\\ncollapsed into a single delivery via \`coalescedCount\` (and recurring\\ntasks past their 7-day window arrive with \`stale: true\` as their final\\ndelivery).\\n\\nTasks do **not** carry over into a brand-new session — they are scoped\\nto the resumed session id, not to the working directory.\\n\\n## Limits\\n\\nA session holds at most 50 live cron tasks; creating one beyond that is rejected.

The subagent runs as a same-process loop instance with its own context and wire file. Delegating also keeps the bulk of intermediate file contents out of your own context — you get a conclusion back instead of a pile of dumps.\\n\\nWriting the prompt:\\n- The subagent starts with zero context — it has not seen this conversation. Brief it like a colleague who just walked into the room: state the goal, list what you already know, hand over the specifics.\\n- Lookups (read this file, run that test): put the exact path or command in the prompt. The subagent should not have to search for things you already know.\\n- Investigations (figure out X, find why Y): give the question, not prescribed steps — fixed steps become dead weight when the premise is wrong.\\n- Do not delegate understanding. If the task hinges on a file path or line number, find it yourself first and write it into the prompt.\\n\\nUsage notes:\\n- When the task continues earlier work a subagent already did, prefer resuming that agent (pass its \`resume\` id) over spawning a fresh instance — the resumed agent keeps its prior context.\\n- A subagent's result is only visible to you, not to the user. When the user needs to see what a subagent produced, summarize the relevant parts yourself in your own reply.\\n- Subagents use a fixed 2-hour timeout. If one times out, resume the same agent instead of starting over.\\n\\nWhen NOT to use Agent: skip delegation for trivial work you can do directly — reading a file whose path you already know, searching a small known set of files, or any task that takes only a step or two. Delegation has a context-handoff cost; it pays off only when the task is substantial enough to outweigh it.\\n\\nOnce a subagent is running, leave that scope to it: do not redo its searches or reads in parallel, and do not abandon it midway and finish the job manually. Both undo the context savings the delegation was meant to buy.\\n\\n\\nWhen \`run_in_background=true\`, the subagent runs detached from this turn. The completion arrives in a later turn as a synthetic user-role message containing its result — you do not need to poll, sleep, or check on its progress. Continue with other work or respond to the user. Never fabricate or predict what the result will say.\\n\\nDefault to a foreground subagent (omit \`run_in_background\`) when your next step needs its result — foreground hands the result straight back. Reach for \`run_in_background=true\` only when you have other work to do while it runs and do not need its result to proceed.

The output may be truncated if it is too long. If the command exits non-zero, the output ends with a \`Command failed with exit code: N\` line; a command killed by its timeout or interrupted by the user ends with its own message instead.\\n\\nIf \`run_in_background=true\`, the command will be started as a background task and this tool will return a task ID instead of waiting for command completion. When doing that, you must provide a short \`description\`. Background commands default to a 600s timeout and \`timeout\` is capped at 86400s; set \`disable_timeout=true\` only when the task should run without a timeout. You will be automatically notified when the task completes. After starting one, default to returning control to the user instead of immediately waiting on it. Use \`TaskOutput\` only for a non-blocking status/output snapshot — do not wait on a task you just launched, since its completion arrives automatically. Use \`TaskStop\` only if the task must be cancelled. If a human user wants to inspect background tasks themselves, point them to the background-task panel.\\n\\n**Guidelines for safety and security:**\\n- Each shell tool call will be executed in a fresh shell environment. The shell variables, current working directory changes, and the shell history is not preserved between calls. To run a command in a particular directory, pass the \`cwd\` argument (or use absolute paths) rather than relying on a \`cd\` from an earlier call.\\n- The tool call will return after the command is finished. You shall not use this tool to execute an interactive command or a command that may run forever. For possibly long-running foreground commands, set the \`timeout\` argument in seconds. Foreground commands default to 60s and allow up to 300s. When a foreground command hits its timeout it is moved to the background instead of being killed, and you will be automatically notified when it completes. The user can also move a running foreground command to the background at any time.\\n- Avoid using \`..\` to access files or directories outside of the working directory.\\n- Avoid modifying files outside of the working directory unless explicitly instructed to do so.\\n- Never run commands that require superuser privileges unless explicitly instructed to do so.\\n- Run git-mutating commands such as \`git commit\`, \`git push\`, \`git reset\`, and \`git rebase\` only when the user asks for them.\\n\\n**Guidelines for efficiency:**\\n- Use \`&&\` to chain commands that genuinely depend on each other, e.g. \`npm install && npm test\`. Independent read-only commands (separate \`git show\`, \`ls\`, or status checks) should be issued as separate parallel Bash calls in one response, not chained into a single call — chaining serializes their execution and mixes their output. Do not stitch outputs together with \`echo\` separators.\\n- Use \`;\` to run commands sequentially regardless of success/failure\\n- Use \`||\` for conditional execution (run second command only if first fails)\\n- Use pipe operations (\`|\`) and redirections (\`>\`, \`>>\`) to chain input and output between commands\\n- Always quote file paths containing spaces with double quotes (e.g., cd \\"/path with spaces/\\")\\n- Compose multi-step logic in a single call with \`if\` / \`case\` / \`for\` / \`while\` control flows.\\n- Prefer \`run_in_background=true\` for long-running builds, tests, watchers, or servers when you need the conversation to continue before the command finishes.\\n\\n**Commands available:**\\nThe following common command categories are usually available. Availability still depends on the host, so when in doubt run \`which <command>\` first to confirm a command exists before relying on it.\\n- Navigation and inspection: \`ls\`, \`pwd\`, \`cd\`, \`stat\`, \`file\`, \`du\`, \`df\`, \`tree\`\\n- File and directory management: \`cp\`, \`mv\`, \`rm\`, \`mkdir\`, \`touch\`, \`ln\`, \`chmod\`, \`chown\`\\n- Text and data processing: \`wc\`, \`sort\`, \`uniq\`, \`cut\`, \`tr\`, \`diff\`, \`xargs\`\\n- Archives and compression: \`tar\`, \`gzip\`, \`gunzip\`, \`zip\`, \`unzip\`\\n- Networking and transfer: \`curl\`, \`wget\`, \`ping\`, \`ssh\`, \`scp\`\\n- Version control: \`git\`; for GitHub-hosted work (PRs, issues, CI runs, API queries) prefer the \`gh\` CLI when installed — it carries the user's GitHub auth and can return structured JSON\\n- Process and system: \`ps\`, \`kill\`, \`top\`, \`env\`, \`date\`, \`uname\`, \`whoami\`\\n- Language and package toolchains: \`node\`, \`npm\`, \`pnpm\`, \`yarn\`, \`python\`, \`pip\` (use whichever the project actually relies on)\\n", "parameters": { "$schema": "http://json-schema.org/draft-07/schema#", "type": "object", "properties": { "command": { "type": "string", "minLength": 1, "description": "The command to execute." }, "cwd": { "description": "The working directory in which to run the command.

The origin carries \`coalescedCount\` showing how many ideal fires were collapsed into this single delivery. You should treat \`coalescedCount > 1\` as \\"I missed some checks; only the latest state matters\\" rather than running the prompt that many times.\\n\\n## Cron-fire envelope\\n\\nWhen a cron task fires, the prompt you scheduled is re-injected wrapped in an XML envelope that exposes the fire context:\\n\\n\`\`\`\\n<cron-fire jobId=\\"...\\" cron=\\"...\\" recurring=\\"true|false\\" coalescedCount=\\"N\\" stale=\\"true|false\\">\\n<prompt>\\nyour original prompt text, verbatim\\n</prompt>\\n</cron-fire>\\n\`\`\`\\n\\nThe envelope is parseable. Use \`coalescedCount > 1\` to know multiple ideal fires were collapsed into a single delivery (treat as \\"only the latest state matters\\"), and \`stale=\\"true\\"\` as a cue that the task is past its 7-day threshold.\\n\\n## 7-day stale behavior\\n\\nRecurring tasks that have been alive for more than 7 days fire one\\nfinal time with \`stale: true\` on the envelope, and the system then\\nauto-deletes the task. The flag is the model's notice that this is\\nthe last delivery. If the schedule is still wanted, call \`CronCreate\`\\nagain with the same \`cron\` and \`prompt\` — that resets \`createdAt\` and\\nstarts a fresh 7-day window. One-shot tasks are never marked stale.\\n\\n## Jitter behavior\\n\\nAnti-herd jitter is applied deterministically per task id:\\n  - Recurring: ideal fire time is shifted **forward** by an offset ≤ min(10% of the cron period, 15 minutes). A \`*/5 * * * *\` task can drift up to 30s; a \`0 9 * * *\` task can drift up to 15 minutes.\\n  - One-shot: only when the ideal fire lands on \`:00\` or \`:30\` of the hour, the fire is pulled **earlier** by ≤ 90 seconds. Other minutes pass through unchanged.\\n\\n## One-shot vs recurring — when to pick which\\n\\nUse \`recurring: false\` for \\"remind me at X\\" style requests, single deadlines, \\"in N minutes do Y\\", and any task that should not repeat. Use \`recurring: true\` for periodic polling (CI status, build watchers, scheduled reports), workday rituals, and anything the user explicitly described as recurring.\\n\\n## Session lifetime\\n\\nCron tasks live in the current session. When you exit, they\\nare persisted under the session homedir; resuming the same session\\nreloads them and the scheduler resumes from each task's \`createdAt\`. Fire times that fell during the offline window are\\ncollapsed into a single delivery via \`coalescedCount\` (and recurring\\ntasks past their 7-day window arrive with \`stale: true\` as their final\\ndelivery).\\n\\nTasks do **not** carry over into a brand-new session — they are scoped\\nto the resumed session id, not to the working directory.\\n\\n## Limits\\n\\nA session holds at most 50 live cron tasks; creating one beyond that is rejected. (The \`prompt\` body is also capped — see its parameter description.) Expressions that never fire within the next 5 years (e.g. \`0 0 31 2 *\`, an impossible date) are rejected at create time.\\n\\n## Returned fields\\n\\n\`id\` (ULID), \`cron\` (the normalized expression), \`humanSchedule\` (English summary), \`recurring\`,\\n\`nextFireAt\` (local ISO timestamp with numeric offset, or null). \`id\` is needed by \`CronDelete\`.\\n\\n## Tell the user how to cancel or modify\\n\\nAfter successfully creating a task, proactively tell the user how they can cancel or modify it later. Users have no direct \`/cron\` command or self-service UI to manage reminders themselves; they must ask the model to make changes (e.g. \\"cancel my 9am reminder\\" or \\"change my daily check to 10am\\").

The subagent runs as a same-process loop instance with its own context and wire file. Delegating also keeps the bulk of intermediate file contents out of your own context — you get a conclusion back instead of a pile of dumps.\\n\\nWriting the prompt:\\n- The subagent starts with zero context — it has not seen this conversation. Brief it like a colleague who just walked into the room: state the goal, list what you already know, hand over the specifics.\\n- Lookups (read this file, run that test): put the exact path or command in the prompt. The subagent should not have to search for things you already know.\\n- Investigations (figure out X, find why Y): give the question, not prescribed steps — fixed steps become dead weight when the premise is wrong.\\n- Do not delegate understanding. If the task hinges on a file path or line number, find it yourself first and write it into the prompt.\\n\\nUsage notes:\\n- When the task continues earlier work a subagent already did, prefer resuming that agent (pass its \`resume\` id) over spawning a fresh instance — the resumed agent keeps its prior context.\\n- A subagent's result is only visible to you, not to the user. When the user needs to see what a subagent produced, summarize the relevant parts yourself in your own reply.\\n- Subagents use a fixed 2-hour timeout. If one times out, resume the same agent instead of starting over.\\n\\nWhen NOT to use Agent: skip delegation for trivial work you can do directly — reading a file whose path you already know, searching a small known set of files, or any task that takes only a step or two. Delegation has a context-handoff cost; it pays off only when the task is substantial enough to outweigh it.\\n\\nOnce a subagent is running, leave that scope to it: do not redo its searches or reads in parallel, and do not abandon it midway and finish the job manually. Both undo the context savings the delegation was meant to buy.\\n\\n\\nWhen \`run_in_background=true\`, the subagent runs detached from this turn. The completion arrives in a later turn as a synthetic user-role message containing its result — you do not need to poll, sleep, or check on its progress. Continue with other work or respond to the user. Never fabricate or predict what the result will say.\\n\\nDefault to a foreground subagent (omit \`run_in_background\`) when your next step needs its result — foreground hands the result straight back. Reach for \`run_in_background=true\` only when you have other work to do while it runs and do not need its result to proceed. Never launch in the background and then immediately wait on it (by polling \`TaskOutput\`, sleeping, or otherwise): that just blocks the turn for no benefit — run it in the foreground instead.\\n\\n\\nAvailable agent types (pass via subagent_type):\\n- plan: Read-only implementation planning and architecture design. Use this agent when the parent agent needs a step-by-step implementation plan, key file identification, and architectural trade-off analysis before code changes are made.\\n  Tools: Read, ReadMediaFile, Glob, Grep, WebSearch, FetchURL\\n- coder: General software engineering agent — the only subagent type with file-editing tools; use it for any delegated task that must modify code. Use this agent for non-trivial software engineering work that may require reading files, editing code, running commands, and returning a compact but technically complete summary to the parent agent.\\n  Tools: Bash, CronCreate, CronDelete, CronList, Edit, EnterPlanMode, ExitPlanMode, Glob, Grep, Read, ReadMediaFile, Skill, TaskList, TaskOutput, TaskStop, TodoList, WaitFor, WebSearch, FetchURL, Write, mcp__*\\n- explore: Fast codebase exploration with prompt-enforced read-only behavior. Fast agent specialized for exploring codebases. Use this when you need to quickly find files by patterns (e.g. \\"src/**/*.yaml\\"), search code for keywords (e.g. \\"database connection\\"), or answer questions about the codebase (e.g. \\"how does the auth module work?\\"). When calling this agent, specify the desired thoroughness level: \\"quick\\" for basic searches, \\"medium\\" for moderate exploration, or \\"thorough\\" for comprehensive analysis across multiple locations and naming conventions.

If the command exits non-zero, the output ends with a \`Command failed with exit code: N\` line; a command killed by its timeout or interrupted by the user ends with its own message instead.\\n\\nIf \`run_in_background=true\`, the command will be started as a background task and this tool will return a task ID instead of waiting for command completion. When doing that, you must provide a short \`description\`. Background commands default to a 600s timeout and \`timeout\` is capped at 86400s; set \`disable_timeout=true\` only when the task should run without a timeout. You will be automatically notified when the task completes. After starting one, default to returning control to the user instead of immediately waiting on it. Use \`TaskOutput\` only for a non-blocking status/output snapshot — do not wait on a task you just launched, since its completion arrives automatically. Use \`TaskStop\` only if the task must be cancelled. If a human user wants to inspect background tasks themselves, point them to the background-task panel.\\n\\n**Guidelines for safety and security:**\\n- Each shell tool call will be executed in a fresh shell environment. The shell variables, current working directory changes, and the shell history is not preserved between calls. To run a command in a particular directory, pass the \`cwd\` argument (or use absolute paths) rather than relying on a \`cd\` from an earlier call.\\n- The tool call will return after the command is finished. You shall not use this tool to execute an interactive command or a command that may run forever. For possibly long-running foreground commands, set the \`timeout\` argument in seconds. Foreground commands default to 60s and allow up to 300s. When a foreground command hits its timeout it is moved to the background instead of being killed, and you will be automatically notified when it completes. The user can also move a running foreground command to the background at any time.\\n- Avoid using \`..\` to access files or directories outside of the working directory.\\n- Avoid modifying files outside of the working directory unless explicitly instructed to do so.\\n- Never run commands that require superuser privileges unless explicitly instructed to do so.\\n- Run git-mutating commands such as \`git commit\`, \`git push\`, \`git reset\`, and \`git rebase\` only when the user asks for them.\\n\\n**Guidelines for efficiency:**\\n- Use \`&&\` to chain commands that genuinely depend on each other, e.g. \`npm install && npm test\`. Independent read-only commands (separate \`git show\`, \`ls\`, or status checks) should be issued as separate parallel Bash calls in one response, not chained into a single call — chaining serializes their execution and mixes their output. Do not stitch outputs together with \`echo\` separators.\\n- Use \`;\` to run commands sequentially regardless of success/failure\\n- Use \`||\` for conditional execution (run second command only if first fails)\\n- Use pipe operations (\`|\`) and redirections (\`>\`, \`>>\`) to chain input and output between commands\\n- Always quote file paths containing spaces with double quotes (e.g., cd \\"/path with spaces/\\")\\n- Compose multi-step logic in a single call with \`if\` / \`case\` / \`for\` / \`while\` control flows.\\n- Prefer \`run_in_background=true\` for long-running builds, tests, watchers, or servers when you need the conversation to continue before the command finishes.\\n\\n**Commands available:**\\nThe following common command categories are usually available. Availability still depends on the host, so when in doubt run \`which <command>\` first to confirm a command exists before relying on it.\\n- Navigation and inspection: \`ls\`, \`pwd\`, \`cd\`, \`stat\`, \`file\`, \`du\`, \`df\`, \`tree\`\\n- File and directory management: \`cp\`, \`mv\`, \`rm\`, \`mkdir\`, \`touch\`, \`ln\`, \`chmod\`, \`chown\`\\n- Text and data processing: \`wc\`, \`sort\`, \`uniq\`, \`cut\`, \`tr\`, \`diff\`, \`xargs\`\\n- Archives and compression: \`tar\`, \`gzip\`, \`gunzip\`, \`zip\`, \`unzip\`\\n- Networking and transfer: \`curl\`, \`wget\`, \`ping\`, \`ssh\`, \`scp\`\\n- Version control: \`git\`; for GitHub-hosted work (PRs, issues, CI runs, API queries) prefer the \`gh\` CLI when installed — it carries the user's GitHub auth and can return structured JSON\\n- Process and system: \`ps\`, \`kill\`, \`top\`, \`env\`, \`date\`, \`uname\`, \`whoami\`\\n- Language and package toolchains: \`node\`, \`npm\`, \`pnpm\`, \`yarn\`, \`python\`, \`pip\` (use whichever the project actually relies on)\\n", "parameters": { "$schema": "http://json-schema.org/draft-07/schema#", "type": "object", "properties": { "command": { "type": "string", "minLength": 1, "description": "The command to execute." }, "cwd": { "description": "The working directory in which to run the command.

A \`*/5 * * * *\` task can drift up to 30s; a \`0 9 * * *\` task can drift up to 15 minutes.\\n  - One-shot: only when the ideal fire lands on \`:00\` or \`:30\` of the hour, the fire is pulled **earlier** by ≤ 90 seconds. Other minutes pass through unchanged.\\n\\n## One-shot vs recurring — when to pick which\\n\\nUse \`recurring: false\` for \\"remind me at X\\" style requests, single deadlines, \\"in N minutes do Y\\", and any task that should not repeat. Use \`recurring: true\` for periodic polling (CI status, build watchers, scheduled reports), workday rituals, and anything the user explicitly described as recurring.\\n\\n## Session lifetime\\n\\nCron tasks live in the current session. When you exit, they\\nare persisted under the session homedir; resuming the same session\\nreloads them and the scheduler resumes from each task's \`createdAt\`. Fire times that fell during the offline window are\\ncollapsed into a single delivery via \`coalescedCount\` (and recurring\\ntasks past their 7-day window arrive with \`stale: true\` as their final\\ndelivery).\\n\\nTasks do **not** carry over into a brand-new session — they are scoped\\nto the resumed session id, not to the working directory.\\n\\n## Limits\\n\\nA session holds at most 50 live cron tasks; creating one beyond that is rejected.

Subject: [PATCH 04/12] fix: stop silently dropping telemetry event attributes

turn_ended now carries the engine error code when a turn fails, session
attribution keys emit empty strings so they survive payload flattening,
and properties a sink cannot accept are reported through a new
onUnexpectedError hook instead of vanishing. Properties are sanitized
when the sink accepts the event, so drops on events queued before
initialization are reported once a handler is installed.

Subject: [PATCH 05/12] fix: tower mission context, review reconciliation and
 spawn metadata

Tower missions take an optional context field that carries the user's own
sentences verbatim into the mission file and every briefing, so worker
and reviewer see the intent and not only a paraphrase. Reviewer briefings
now include the mission text and the author's own report with an
intent-first checklist, and workers escalate substantive ambiguity to the
tower instead of guessing.

Tower spawns honour the configured subagent timeout instead of a fixed
two hours, and the /tasks list shows each background agent's model.

 Usage notes:
 - When the task continues earlier work a subagent already did, prefer resuming that agent (pass its `resume` id) over spawning a fresh instance — the resumed agent keeps its prior context.
 - A subagent's result is only visible to you, not to the user. When the user needs to see what a subagent produced, summarize the relevant parts yourself in your own reply.
-- Subagents use a fixed 2-hour timeout. If one times out, resume the same agent instead of starting over.
 
 When NOT to use Agent: skip delegation for trivial work you can do directly — reading a file whose path you already know, searching a small known set of files, or any task that takes only a step or two. Delegation has a context-handoff cost; it pays off only when the task is substantial enough to outweigh it.

 ## Tower workflow
 
 1. **Init** — `TowerInit`. It creates `.tower/` and records the base branch — when the human enabled tower mode with `/tower <base>`, the workspace and base branch are already set up, so `TowerInit` just confirms them. Workers and reviewers never prompt for tool approvals — they are pinned to the auto permission mode at spawn, whatever the session's mode. Your own orchestration calls still follow the session mode, so if it would interrupt you with constant prompts, tell the human once that a more autonomous mode fits tower better — then proceed regardless. When `TowerInit` reports carried-over open missions from a previous session, settle them **before planning**: continue the ones that belong to the current objective with fresh workers, and abandon the unrelated ones (`TowerMission status=abandoned`) — missions that are neither merged nor abandoned keep their scopes reserved, so `TowerPlan` rejects any new mission overlapping them.
-2. **Plan** — break the objective into 2–4 missions and call `TowerPlan` with each mission's title, **disjoint** scope globs (picomatch: `**` crosses directories), tasks, and dependencies. Mark read-only investigation missions `kind: "survey"`: a survey's scope is informational (it reserves nothing, so surveys and builds may overlap the same paths), the worker must not change code, and it closes with a zero-diff `TowerMerge` — no reviewer needed. Shared files (lockfiles, central configs) belong to exactly one build mission or to your own integration work. Post the plan to the human in one compact message and launch immediately — their words are plan changes, never a gate.
+2. **Plan** — break the objective into 2–4 missions and call `TowerPlan` with each mission's title, **disjoint** scope globs (picomatch: `**` crosses directories), tasks, and dependencies. Write tasks as **verifiable** items a reviewer can map to the diff, and when the human's own words carry intent your paraphrase could lose, copy the key sentences into the mission's `context` **verbatim** — when in doubt, include it. `context` supplements your paraphrase (never replaces it, never holds the full conversation history) and is the one channel that carries the human's voice to both worker and reviewer. Mark read-only investigation missions `kind: "survey"`: a survey's scope is informational (it reserves nothing, so surveys and builds may overlap the same paths), the worker must not change code, and it closes with a zero-diff `TowerMerge` — no reviewer needed. Shared files (lockfiles, central configs) belong to exactly one build mission or to your own integration work. Post the plan to the human in one compact message and launch immediately — their words are plan changes, never a gate.
 3. **Spawn** — one `TowerSpawn` per mission (`kind: "worker"`, background, code-built briefing), and **spawn every dependency-unblocked mission right away**: fire the `TowerSpawn` calls back to back, never trickle them out one at a time and never wait for one worker before launching the next — the fleet exists to run in parallel. The tool refuses duplicate names — resume the existing agent with the `Agent` tool instead. Workers commit on their branch; their completion wakes you. Once the batch is running, **end your turn**: completions and inbox traffic arrive as notifications, so never poll `TowerInbox`/`TowerStatus` in a loop and never sit synchronously waiting on a worker. Workers bind the configured secondary model when the secondary-model experiment is on (they inherit your model otherwise); reviewers always bind your primary model — review quality is not where you save. The resolved model is shown in the spawn output and the `spawn` line of `activity.log`.
 4. **Supervise** — on every wake (worker completion, human message): `TowerInbox` and `TowerStatus`, then act:
-   - Review request → `TowerSpawn` a reviewer (`kind: "reviewer"`, `review_target` the branch). Do not review mission code yourself. Survey missions skip review — close them with `TowerMerge` once their summary lands.
+   - Review request → first reconcile the worker's report against the mission tasks **item by item** (a silently dropped task means the mission is not done — send it back), then `TowerSpawn` a reviewer (`kind: "reviewer"`, `review_target` the branch) — the briefing hands the reviewer the mission text and the worker's report, so the review verifies intent, not only code health. Do not review mission code yourself. Survey missions skip review — close them with `TowerMerge` once their summary lands.
    - Review verdict not clean → resume the author (Agent tool) pointing at the review file; the author fixes, pushes, and requests re-review. Round cap: at 5 rounds, or when two consecutive rounds report the same findings, stop the loop, inform the human, and redirect (reassign, split, descope).
    - Blocker → answer or reassign if you can; if it genuinely needs the human, inform them and keep the rest moving.
    - Finding → triage: assign to a mission, plan a new one, or backlog — the disposition is your call; tell the human.

 Split the tower goal into missions. Each mission gets an id (M1, M2, …), a branch (feat/<slug>), and an isolated git worktree (.tower/worktrees/wt-N).
 
+Write tasks as verifiable check items — the worker ticks them off, the completion report reconciles against them item by item, and the reviewer maps every one to the diff. When the user's own words carry intent your paraphrase could lose, copy the key sentences into `context` verbatim (when in doubt, include it): context supplements your paraphrase, never replaces it, travels with the mission into the worker and reviewer briefings, and is never the full conversation history.

 Rules enforced by the store: scopes of build missions must be pairwise disjoint (survey missions are read-only and reserve no scope), and deps must reference existing mission ids. Plan once, then spawn one worker per mission with TowerSpawn. Requires an active tower workspace (run TowerInit first).

 Spawn a tower worker or reviewer as a background subagent and register it in the tower roster.

+Workers: pass mission_id — the tool creates the mission worktree, marks the mission active with this worker as owner, and briefs the agent with the full mission text. Reviewers: pass review_target — when the branch belongs to a mission, the briefing carries the full mission text (title, tasks, and any verbatim user context) plus the author's own review-request when one is on file, so the review verifies intent against the mission, not only code health; the agent must submit its verdict via TowerReview.
 
 If the base checkout has uncommitted changes (staged, unstaged, or untracked) when a worker spawns, the tool captures them as a snapshot commit that becomes the mission branch's first commit — the worker starts from HEAD + that WIP instead of plain HEAD. The checkout itself is never touched (nothing is committed, staged, or stashed there), and the merge gate later diffs the branch from that snapshot while it remains part of the branch's history (falling back to the base branch once a rebase drops the snapshot commit), so the WIP is never mistaken for the worker's own scope. Snapshotting requires the main checkout to be on the recorded base branch: WIP sitting on a different branch (or a detached HEAD) belongs to that line of work, so the spawn is refused rather than mixing that content into the base — switch back to the base or commit/stash first. The snapshot only happens when the branch is first created; re-adding an existing branch reuses it as-is.

The subagent runs as a same-process loop instance with its own context and wire file. Delegating also keeps the bulk of intermediate file contents out of your own context — you get a conclusion back instead of a pile of dumps.\\n\\nWriting the prompt:\\n- The subagent starts with zero context — it has not seen this conversation. Brief it like a colleague who just walked into the room: state the goal, list what you already know, hand over the specifics.\\n- Lookups (read this file, run that test): put the exact path or command in the prompt. The subagent should not have to search for things you already know.\\n- Investigations (figure out X, find why Y): give the question, not prescribed steps — fixed steps become dead weight when the premise is wrong.\\n- Do not delegate understanding. If the task hinges on a file path or line number, find it yourself first and write it into the prompt.\\n\\nUsage notes:\\n- When the task continues earlier work a subagent already did, prefer resuming that agent (pass its \`resume\` id) over spawning a fresh instance — the resumed agent keeps its prior context.\\n- A subagent's result is only visible to you, not to the user. When the user needs to see what a subagent produced, summarize the relevant parts yourself in your own reply.\\n- Subagents use a fixed 2-hour timeout. If one times out, resume the same agent instead of starting over.\\n\\nWhen NOT to use Agent: skip delegation for trivial work you can do directly — reading a file whose path you already know, searching a small known set of files, or any task that takes only a step or two. Delegation has a context-handoff cost; it pays off only when the task is substantial enough to outweigh it.\\n\\nOnce a subagent is running, leave that scope to it: do not redo its searches or reads in parallel, and do not abandon it midway and finish the job manually. Both undo the context savings the delegation was meant to buy.\\n\\n\\nWhen \`run_in_background=true\`, the subagent runs detached from this turn. The completion arrives in a later turn as a synthetic user-role message containing its result — you do not need to poll, sleep, or check on its progress. Continue with other work or respond to the user. Never fabricate or predict what the result will say.\\n\\nDefault to a foreground subagent (omit \`run_in_background\`) when your next step needs its result — foreground hands the result straight back. Reach for \`run_in_background=true\` only when you have other work to do while it runs and do not need its result to proceed. Never launch in the background and then immediately wait on it (by polling \`TaskOutput\`, sleeping, or otherwise): that just blocks the turn for no benefit — run it in the foreground instead.\\n\\n\\nAvailable agent types (pass via subagent_type):\\n- plan: Read-only implementation planning and architecture design. Use this agent when the parent agent needs a step-by-step implementation plan, key file identification, and architectural trade-off analysis before code changes are made.\\n  Tools: Read, ReadMediaFile, Glob, Grep, WebSearch, FetchURL\\n- coder: General software engineering agent — the only subagent type with file-editing tools; use it for any delegated task that must modify code. Use this agent for non-trivial software engineering work that may require reading files, editing code, running commands, and returning a compact but technically complete summary to the parent agent.\\n  Tools: Bash, CronCreate, CronDelete, CronList, Edit, EnterPlanMode, ExitPlanMode, Glob, Grep, Read, ReadMediaFile, Skill, TaskList, TaskOutput, TaskStop, TodoList, WaitFor, WebSearch, FetchURL, Write, mcp__*\\n- explore: Fast codebase exploration with prompt-enforced read-only behavior. Fast agent specialized for exploring codebases. Use this when you need to quickly find files by patterns (e.g. \\"src/**/*.yaml\\"), search code for keywords (e.g. \\"database connection\\"), or answer questions about the codebase (e.g. \\"how does the auth module work?\\"). When calling this agent, specify the desired thoroughness level: \\"quick\\" for basic searches, \\"medium\\" for moderate exploration, or \\"thorough\\" for comprehensive analysis across multiple locations and naming conventions.

Use this for shell semantics — pipes, env, processes, git, package managers, build/test runners, anything genuinely interactive or multi-step.\\n\\n**Translate these to a dedicated tool instead:**\\n- \`cat\` / \`head\` / \`tail\` (known path) → \`Read\`\\n- \`sed\` / \`awk\` (in-place edit) → \`Edit\`\\n- \`echo > file\` / \`cat <<EOF\` → \`Write\`\\n- \`find\` / recursive \`ls\` to locate files by name pattern → \`Glob\` (plain \`ls <known-directory>\` is fine for listing a directory)\\n- \`grep\` / \`rg\` (search file contents) → \`Grep\`\\n- \`echo\` / \`printf\` (talk to the user) → just output text directly\\n\\nThe dedicated tools render in the per-tool permission UI and keep raw stdout out of the conversation; that is why they are worth reaching for whenever one fits.\\n\\n**Output:**\\nThe stdout and stderr will be combined and returned as a string. The output may be truncated if it is too long. If the command exits non-zero, the output ends with a \`Command failed with exit code: N\` line; a command killed by its timeout or interrupted by the user ends with its own message instead.\\n\\nIf \`run_in_background=true\`, the command will be started as a background task and this tool will return a task ID instead of waiting for command completion. When doing that, you must provide a short \`description\`. Background commands default to a 600s timeout and \`timeout\` is capped at 86400s; set \`disable_timeout=true\` only when the task should run without a timeout. You will be automatically notified when the task completes. After starting one, default to returning control to the user instead of immediately waiting on it. Use \`TaskOutput\` only for a non-blocking status/output snapshot — do not wait on a task you just launched, since its completion arrives automatically. Use \`TaskStop\` only if the task must be cancelled. If a human user wants to inspect background tasks themselves, point them to the background-task panel.\\n\\n**Guidelines for safety and security:**\\n- Each shell tool call will be executed in a fresh shell environment. The shell variables, current working directory changes, and the shell history is not preserved between calls. To run a command in a particular directory, pass the \`cwd\` argument (or use absolute paths) rather than relying on a \`cd\` from an earlier call.\\n- The tool call will return after the command is finished. You shall not use this tool to execute an interactive command or a command that may run forever. For possibly long-running foreground commands, set the \`timeout\` argument in seconds. Foreground commands default to 60s and allow up to 300s. When a foreground command hits its timeout it is moved to the background instead of being killed, and you will be automatically notified when it completes. The user can also move a running foreground command to the background at any time.\\n- Avoid using \`..\` to access files or directories outside of the working directory.\\n- Avoid modifying files outside of the working directory unless explicitly instructed to do so.\\n- Never run commands that require superuser privileges unless explicitly instructed to do so.\\n- Run git-mutating commands such as \`git commit\`, \`git push\`, \`git reset\`, and \`git rebase\` only when the user asks for them.\\n\\n**Guidelines for efficiency:**\\n- Use \`&&\` to chain commands that genuinely depend on each other, e.g. \`npm install && npm test\`. Independent read-only commands (separate \`git show\`, \`ls\`, or status checks) should be issued as separate parallel Bash calls in one response, not chained into a single call — chaining serializes their execution and mixes their output. Do not stitch outputs together with \`echo\` separators.\\n- Use \`;\` to run commands sequentially regardless of success/failure\\n- Use \`||\` for conditional execution (run second command only if first fails)\\n- Use pipe operations (\`|\`) and redirections (\`>\`, \`>>\`) to chain input and output between commands\\n- Always quote file paths containing spaces with double quotes (e.g., cd \\"/path with spaces/\\")\\n- Compose multi-step logic in a single call with \`if\` / \`case\` / \`for\` / \`while\` control flows.\\n- Prefer \`run_in_background=true\` for long-running builds, tests, watchers, or servers when you need the conversation to continue before the command finishes.\\n\\n**Commands available:**\\nThe following common command categories are usually available. Availability still depends on the host, so when in doubt run \`which <command>\` first to confirm a command exists before relying on it.\\n- Navigation and inspection: \`ls\`, \`pwd\`, \`cd\`, \`stat\`, \`file\`, \`du\`, \`df\`, \`tree\`\\n- File and directory management: \`cp\`, \`mv\`, \`rm\`, \`mkdir\`, \`touch\`, \`ln\`, \`chmod\`, \`chown\`\\n- Text and data processing: \`wc\`, \`sort\`, \`uniq\`, \`cut\`, \`tr\`, \`diff\`, \`xargs\`\\n- Archives and compression: \`tar\`, \`gzip\`, \`gunzip\`, \`zip\`, \`unzip\`\\n- Networking and transfer: \`curl\`, \`wget\`, \`ping\`, \`ssh\`, \`scp\`\\n- Version control: \`git\`; for GitHub-hosted work (PRs, issues, CI runs, API queries) prefer the \`gh\` CLI when installed — it carries the user's GitHub auth and can return structured JSON\\n- Process and system: \`ps\`, \`kill\`, \`top\`, \`env\`, \`date\`, \`uname\`, \`whoami\`\\n- Language and package toolchains: \`node\`, \`npm\`, \`pnpm\`, \`yarn\`, \`python\`, \`pip\` (use whichever the project actually relies on)\\n", "parameters": { "$schema": "http://json-schema.org/draft-07/schema#", "type": "object", "properties": { "command": { "type": "string", "minLength": 1, "description": "The command to execute." }, "cwd": { "description": "The working directory in which to run the command.

The origin carries \`coalescedCount\` showing how many ideal fires were collapsed into this single delivery. You should treat \`coalescedCount > 1\` as \\"I missed some checks; only the latest state matters\\" rather than running the prompt that many times.\\n\\n## Cron-fire envelope\\n\\nWhen a cron task fires, the prompt you scheduled is re-injected wrapped in an XML envelope that exposes the fire context:\\n\\n\`\`\`\\n<cron-fire jobId=\\"...\\" cron=\\"...\\" recurring=\\"true|false\\" coalescedCount=\\"N\\" stale=\\"true|false\\">\\n<prompt>\\nyour original prompt text, verbatim\\n</prompt>\\n</cron-fire>\\n\`\`\`\\n\\nThe envelope is parseable. Use \`coalescedCount > 1\` to know multiple ideal fires were collapsed into a single delivery (treat as \\"only the latest state matters\\"), and \`stale=\\"true\\"\` as a cue that the task is past its 7-day threshold.\\n\\n## 7-day stale behavior\\n\\nRecurring tasks that have been alive for more than 7 days fire one\\nfinal time with \`stale: true\` on the envelope, and the system then\\nauto-deletes the task. The flag is the model's notice that this is\\nthe last delivery. If the schedule is still wanted, call \`CronCreate\`\\nagain with the same \`cron\` and \`prompt\` — that resets \`createdAt\` and\\nstarts a fresh 7-day window. One-shot tasks are never marked stale.\\n\\n## Jitter behavior\\n\\nAnti-herd jitter is applied deterministically per task id:\\n  - Recurring: ideal fire time is shifted **forward** by an offset ≤ min(10% of the cron period, 15 minutes). A \`*/5 * * * *\` task can drift up to 30s; a \`0 9 * * *\` task can drift up to 15 minutes.\\n  - One-shot: only when the ideal fire lands on \`:00\` or \`:30\` of the hour, the fire is pulled **earlier** by ≤ 90 seconds. Other minutes pass through unchanged.\\n\\n## One-shot vs recurring — when to pick which\\n\\nUse \`recurring: false\` for \\"remind me at X\\" style requests, single deadlines, \\"in N minutes do Y\\", and any task that should not repeat. Use \`recurring: true\` for periodic polling (CI status, build watchers, scheduled reports), workday rituals, and anything the user explicitly described as recurring.\\n\\n## Session lifetime\\n\\nCron tasks live in the current session. When you exit, they\\nare persisted under the session homedir; resuming the same session\\nreloads them and the scheduler resumes from each task's \`createdAt\`. Fire times that fell during the offline window are\\ncollapsed into a single delivery via \`coalescedCount\` (and recurring\\ntasks past their 7-day window arrive with \`stale: true\` as their final\\ndelivery).\\n\\nTasks do **not** carry over into a brand-new session — they are scoped\\nto the resumed session id, not to the working directory.\\n\\n## Limits\\n\\nA session holds at most 50 live cron tasks; creating one beyond that is rejected. (The \`prompt\` body is also capped — see its parameter description.)

Users have no direct \`/cron\` command or self-service UI to manage reminders themselves; they must ask the model to make changes (e.g. \\"cancel my 9am reminder\\" or \\"change my daily check to 10am\\").

The subagent runs as a same-process loop instance with its own context and wire file. Delegating also keeps the bulk of intermediate file contents out of your own context — you get a conclusion back instead of a pile of dumps.\\n\\nWriting the prompt:\\n- The subagent starts with zero context — it has not seen this conversation. Brief it like a colleague who just walked into the room: state the goal, list what you already know, hand over the specifics.\\n- Lookups (read this file, run that test): put the exact path or command in the prompt. The subagent should not have to search for things you already know.\\n- Investigations (figure out X, find why Y): give the question, not prescribed steps — fixed steps become dead weight when the premise is wrong.\\n- Do not delegate understanding. If the task hinges on a file path or line number, find it yourself first and write it into the prompt.\\n\\nUsage notes:\\n- When the task continues earlier work a subagent already did, prefer resuming that agent (pass its \`resume\` id) over spawning a fresh instance — the resumed agent keeps its prior context.\\n- A subagent's result is only visible to you, not to the user. When the user needs to see what a subagent produced, summarize the relevant parts yourself in your own reply.\\n\\nWhen NOT to use Agent: skip delegation for trivial work you can do directly — reading a file whose path you already know, searching a small known set of files, or any task that takes only a step or two. Delegation has a context-handoff cost; it pays off only when the task is substantial enough to outweigh it.\\n\\nOnce a subagent is running, leave that scope to it: do not redo its searches or reads in parallel, and do not abandon it midway and finish the job manually. Both undo the context savings the delegation was meant to buy.\\n\\n\\nWhen \`run_in_background=true\`, the subagent runs detached from this turn. The completion arrives in a later turn as a synthetic user-role message containing its result — you do not need to poll, sleep, or check on its progress. Continue with other work or respond to the user. Never fabricate or predict what the result will say.\\n\\nDefault to a foreground subagent (omit \`run_in_background\`) when your next step needs its result — foreground hands the result straight back. Reach for \`run_in_background=true\` only when you have other work to do while it runs and do not need its result to proceed. Never launch in the background and then immediately wait on it (by polling \`TaskOutput\`, sleeping, or otherwise): that just blocks the turn for no benefit — run it in the foreground instead.\\n\\n\\nAvailable agent types (pass via subagent_type):\\n- plan: Read-only implementation planning and architecture design. Use this agent when the parent agent needs a step-by-step implementation plan, key file identification, and architectural trade-off analysis before code changes are made.\\n  Tools: Read, ReadMediaFile, Glob, Grep, WebSearch, FetchURL\\n- coder: General software engineering agent — the only subagent type with file-editing tools; use it for any delegated task that must modify code. Use this agent for non-trivial software engineering work that may require reading files, editing code, running commands, and returning a compact but technically complete summary to the parent agent.\\n  Tools: Bash, CronCreate, CronDelete, CronList, Edit, EnterPlanMode, ExitPlanMode, Glob, Grep, Read, ReadMediaFile, Skill, TaskList, TaskOutput, TaskStop, TodoList, WaitFor, WebSearch, FetchURL, Write, mcp__*\\n- explore: Fast codebase exploration with prompt-enforced read-only behavior. Fast agent specialized for exploring codebases. Use this when you need to quickly find files by patterns (e.g. \\"src/**/*.yaml\\"), search code for keywords (e.g. \\"database connection\\"), or answer questions about the codebase (e.g. \\"how does the auth module work?\\"). When calling this agent, specify the desired thoroughness level: \\"quick\\" for basic searches, \\"medium\\" for moderate exploration, or \\"thorough\\" for comprehensive analysis across multiple locations and naming conventions.

If the command exits non-zero, the output ends with a \`Command failed with exit code: N\` line; a command killed by its timeout or interrupted by the user ends with its own message instead.\\n\\nIf \`run_in_background=true\`, the command will be started as a background task and this tool will return a task ID instead of waiting for command completion. When doing that, you must provide a short \`description\`. Background commands default to a 600s timeout and \`timeout\` is capped at 86400s; set \`disable_timeout=true\` only when the task should run without a timeout. You will be automatically notified when the task completes. After starting one, default to returning control to the user instead of immediately waiting on it. Use \`TaskOutput\` only for a non-blocking status/output snapshot — do not wait on a task you just launched, since its completion arrives automatically. Use \`TaskStop\` only if the task must be cancelled. If a human user wants to inspect background tasks themselves, point them to the background-task panel.\\n\\n**Guidelines for safety and security:**\\n- Each shell tool call will be executed in a fresh shell environment. The shell variables, current working directory changes, and the shell history is not preserved between calls. To run a command in a particular directory, pass the \`cwd\` argument (or use absolute paths) rather than relying on a \`cd\` from an earlier call.\\n- The tool call will return after the command is finished. You shall not use this tool to execute an interactive command or a command that may run forever. For possibly long-running foreground commands, set the \`timeout\` argument in seconds. Foreground commands default to 60s and allow up to 300s. When a foreground command hits its timeout it is moved to the background instead of being killed, and you will be automatically notified when it completes. The user can also move a running foreground command to the background at any time.\\n- Avoid using \`..\` to access files or directories outside of the working directory.\\n- Avoid modifying files outside of the working directory unless explicitly instructed to do so.\\n- Never run commands that require superuser privileges unless explicitly instructed to do so.\\n- Run git-mutating commands such as \`git commit\`, \`git push\`, \`git reset\`, and \`git rebase\` only when the user asks for them.\\n\\n**Guidelines for efficiency:**\\n- Use \`&&\` to chain commands that genuinely depend on each other, e.g. \`npm install && npm test\`. Independent read-only commands (separate \`git show\`, \`ls\`, or status checks) should be issued as separate parallel Bash calls in one response, not chained into a single call — chaining serializes their execution and mixes their output. Do not stitch outputs together with \`echo\` separators.\\n- Use \`;\` to run commands sequentially regardless of success/failure\\n- Use \`||\` for conditional execution (run second command only if first fails)\\n- Use pipe operations (\`|\`) and redirections (\`>\`, \`>>\`) to chain input and output between commands\\n- Always quote file paths containing spaces with double quotes (e.g., cd \\"/path with spaces/\\")\\n- Compose multi-step logic in a single call with \`if\` / \`case\` / \`for\` / \`while\` control flows.\\n- Prefer \`run_in_background=true\` for long-running builds, tests, watchers, or servers when you need the conversation to continue before the command finishes.\\n\\n**Commands available:**\\nThe following common command categories are usually available. Availability still depends on the host, so when in doubt run \`which <command>\` first to confirm a command exists before relying on it.\\n- Navigation and inspection: \`ls\`, \`pwd\`, \`cd\`, \`stat\`, \`file\`, \`du\`, \`df\`, \`tree\`\\n- File and directory management: \`cp\`, \`mv\`, \`rm\`, \`mkdir\`, \`touch\`, \`ln\`, \`chmod\`, \`chown\`\\n- Text and data processing: \`wc\`, \`sort\`, \`uniq\`, \`cut\`, \`tr\`, \`diff\`, \`xargs\`\\n- Archives and compression: \`tar\`, \`gzip\`, \`gunzip\`, \`zip\`, \`unzip\`\\n- Networking and transfer: \`curl\`, \`wget\`, \`ping\`, \`ssh\`, \`scp\`\\n- Version control: \`git\`; for GitHub-hosted work (PRs, issues, CI runs, API queries) prefer the \`gh\` CLI when installed — it carries the user's GitHub auth and can return structured JSON\\n- Process and system: \`ps\`, \`kill\`, \`top\`, \`env\`, \`date\`, \`uname\`, \`whoami\`\\n- Language and package toolchains: \`node\`, \`npm\`, \`pnpm\`, \`yarn\`, \`python\`, \`pip\` (use whichever the project actually relies on)\\n", "parameters": { "$schema": "http://json-schema.org/draft-07/schema#", "type": "object", "properties": { "command": { "type": "string", "minLength": 1, "description": "The command to execute." }, "cwd": { "description": "The working directory in which to run the command.

Use \`coalescedCount > 1\` to know multiple ideal fires were collapsed into a single delivery (treat as \\"only the latest state matters\\"), and \`stale=\\"true\\"\` as a cue that the task is past its 7-day threshold.\\n\\n## 7-day stale behavior\\n\\nRecurring tasks that have been alive for more than 7 days fire one\\nfinal time with \`stale: true\` on the envelope, and the system then\\nauto-deletes the task. The flag is the model's notice that this is\\nthe last delivery.

One-shot tasks are never marked stale.\\n\\n## Jitter behavior\\n\\nAnti-herd jitter is applied deterministically per task id:\\n  - Recurring: ideal fire time is shifted **forward** by an offset ≤ min(10% of the cron period, 15 minutes). A \`*/5 * * * *\` task can drift up to 30s; a \`0 9 * * *\` task can drift up to 15 minutes.\\n  - One-shot: only when the ideal fire lands on \`:00\` or \`:30\` of the hour, the fire is pulled **earlier** by ≤ 90 seconds. Other minutes pass through unchanged.\\n\\n## One-shot vs recurring — when to pick which\\n\\nUse \`recurring: false\` for \\"remind me at X\\" style requests, single deadlines, \\"in N minutes do Y\\", and any task that should not repeat. Use \`recurring: true\` for periodic polling (CI status, build watchers, scheduled reports), workday rituals, and anything the user explicitly described as recurring.\\n\\n## Session lifetime\\n\\nCron tasks live in the current session. When you exit, they\\nare persisted under the session homedir; resuming the same session\\nreloads them and the scheduler resumes from each task's \`createdAt\`.

The subagent runs as a same-process loop instance with its own context and wire file. Delegating also keeps the bulk of intermediate file contents out of your own context — you get a conclusion back instead of a pile of dumps.\\n\\nWriting the prompt:\\n- The subagent starts with zero context — it has not seen this conversation. Brief it like a colleague who just walked into the room: state the goal, list what you already know, hand over the specifics.\\n- Lookups (read this file, run that test): put the exact path or command in the prompt. The subagent should not have to search for things you already know.\\n- Investigations (figure out X, find why Y): give the question, not prescribed steps — fixed steps become dead weight when the premise is wrong.\\n- Do not delegate understanding. If the task hinges on a file path or line number, find it yourself first and write it into the prompt.\\n\\nUsage notes:\\n- When the task continues earlier work a subagent already did, prefer resuming that agent (pass its \`resume\` id) over spawning a fresh instance — the resumed agent keeps its prior context.\\n- A subagent's result is only visible to you, not to the user. When the user needs to see what a subagent produced, summarize the relevant parts yourself in your own reply.\\n- Subagents use a fixed 2-hour timeout. If one times out, resume the same agent instead of starting over.\\n\\nWhen NOT to use Agent: skip delegation for trivial work you can do directly — reading a file whose path you already know, searching a small known set of files, or any task that takes only a step or two. Delegation has a context-handoff cost; it pays off only when the task is substantial enough to outweigh it.\\n\\nOnce a subagent is running, leave that scope to it: do not redo its searches or reads in parallel, and do not abandon it midway and finish the job manually. Both undo the context savings the delegation was meant to buy.\\n\\n\\nWhen \`run_in_background=true\`, the subagent runs detached from this turn. The completion arrives in a later turn as a synthetic user-role message containing its result — you do not need to poll, sleep, or check on its progress. Continue with other work or respond to the user. Never fabricate or predict what the result will say.\\n\\nDefault to a foreground subagent (omit \`run_in_background\`) when your next step needs its result — foreground hands the result straight back. Reach for \`run_in_background=true\` only when you have other work to do while it runs and do not need its result to proceed. Never launch in the background and then immediately wait on it (by polling \`TaskOutput\`, sleeping, or otherwise): that just blocks the turn for no benefit — run it in the foreground instead.\\n\\n\\nAvailable agent types (pass via subagent_type):\\n- plan: Read-only implementation planning and architecture design. Use this agent when the parent agent needs a step-by-step implementation plan, key file identification, and architectural trade-off analysis before code changes are made.\\n  Tools: Read, ReadMediaFile, Glob, Grep, WebSearch, FetchURL\\n- coder: General software engineering agent — the only subagent type with file-editing tools; use it for any delegated task that must modify code. Use this agent for non-trivial software engineering work that may require reading files, editing code, running commands, and returning a compact but technically complete summary to the parent agent.\\n  Tools: Bash, CronCreate, CronDelete, CronList, Edit, EnterPlanMode, ExitPlanMode, Glob, Grep, Read, ReadMediaFile, Skill, TaskList, TaskOutput, TaskStop, TodoList, WaitFor, WebSearch, FetchURL, Write, mcp__*\\n- explore: Fast codebase exploration with prompt-enforced read-only behavior. Fast agent specialized for exploring codebases. Use this when you need to quickly find files by patterns (e.g. \\"src/**/*.yaml\\"), search code for keywords (e.g. \\"database connection\\"), or answer questions about the codebase (e.g. \\"how does the auth module work?\\"). When calling this agent, specify the desired thoroughness level: \\"quick\\" for basic searches, \\"medium\\" for moderate exploration, or \\"thorough\\" for comprehensive analysis across multiple locations and naming conventions. Use this agent for any read-only exploration that will clearly require more than 3 search queries.

The output may be truncated if it is too long. If the command exits non-zero, the output ends with a \`Command failed with exit code: N\` line; a command killed by its timeout or interrupted by the user ends with its own message instead.\\n\\nIf \`run_in_background=true\`, the command will be started as a background task and this tool will return a task ID instead of waiting for command completion. When doing that, you must provide a short \`description\`. Background commands default to a 600s timeout and \`timeout\` is capped at 86400s; set \`disable_timeout=true\` only when the task should run without a timeout. You will be automatically notified when the task completes. After starting one, default to returning control to the user instead of immediately waiting on it. Use \`TaskOutput\` only for a non-blocking status/output snapshot — do not wait on a task you just launched, since its completion arrives automatically. Use \`TaskStop\` only if the task must be cancelled. If a human user wants to inspect background tasks themselves, point them to the background-task panel.\\n\\n**Guidelines for safety and security:**\\n- Each shell tool call will be executed in a fresh shell environment. The shell variables, current working directory changes, and the shell history is not preserved between calls. To run a command in a particular directory, pass the \`cwd\` argument (or use absolute paths) rather than relying on a \`cd\` from an earlier call.\\n- The tool call will return after the command is finished. You shall not use this tool to execute an interactive command or a command that may run forever. For possibly long-running foreground commands, set the \`timeout\` argument in seconds. Foreground commands default to 60s and allow up to 300s. When a foreground command hits its timeout it is moved to the background instead of being killed, and you will be automatically notified when it completes. The user can also move a running foreground command to the background at any time.\\n- Avoid using \`..\` to access files or directories outside of the working directory.\\n- Avoid modifying files outside of the working directory unless explicitly instructed to do so.\\n- Never run commands that require superuser privileges unless explicitly instructed to do so.\\n- Run git-mutating commands such as \`git commit\`, \`git push\`, \`git reset\`, and \`git rebase\` only when the user asks for them.\\n\\n**Guidelines for efficiency:**\\n- Use \`&&\` to chain commands that genuinely depend on each other, e.g. \`npm install && npm test\`. Independent read-only commands (separate \`git show\`, \`ls\`, or status checks) should be issued as separate parallel Bash calls in one response, not chained into a single call — chaining serializes their execution and mixes their output. Do not stitch outputs together with \`echo\` separators.\\n- Use \`;\` to run commands sequentially regardless of success/failure\\n- Use \`||\` for conditional execution (run second command only if first fails)\\n- Use pipe operations (\`|\`) and redirections (\`>\`, \`>>\`) to chain input and output between commands\\n- Always quote file paths containing spaces with double quotes (e.g., cd \\"/path with spaces/\\")\\n- Compose multi-step logic in a single call with \`if\` / \`case\` / \`for\` / \`while\` control flows.\\n- Prefer \`run_in_background=true\` for long-running builds, tests, watchers, or servers when you need the conversation to continue before the command finishes.\\n\\n**Commands available:**\\nThe following common command categories are usually available. Availability still depends on the host, so when in doubt run \`which <command>\` first to confirm a command exists before relying on it.\\n- Navigation and inspection: \`ls\`, \`pwd\`, \`cd\`, \`stat\`, \`file\`, \`du\`, \`df\`, \`tree\`\\n- File and directory management: \`cp\`, \`mv\`, \`rm\`, \`mkdir\`, \`touch\`, \`ln\`, \`chmod\`, \`chown\`\\n- Text and data processing: \`wc\`, \`sort\`, \`uniq\`, \`cut\`, \`tr\`, \`diff\`, \`xargs\`\\n- Archives and compression: \`tar\`, \`gzip\`, \`gunzip\`, \`zip\`, \`unzip\`\\n- Networking and transfer: \`curl\`, \`wget\`, \`ping\`, \`ssh\`, \`scp\`\\n- Version control: \`git\`; for GitHub-hosted work (PRs, issues, CI runs, API queries) prefer the \`gh\` CLI when installed — it carries the user's GitHub auth and can return structured JSON\\n- Process and system: \`ps\`, \`kill\`, \`top\`, \`env\`, \`date\`, \`uname\`, \`whoami\`\\n- Language and package toolchains: \`node\`, \`npm\`, \`pnpm\`, \`yarn\`, \`python\`, \`pip\` (use whichever the project actually relies on)\\n", "parameters": { "$schema": "http://json-schema.org/draft-07/schema#", "type": "object", "properties": { "command": { "type": "string", "minLength": 1, "description": "The command to execute." }, "cwd": { "description": "The working directory in which to run the command.

When in doubt, nudge a few minutes early or late — the user will not notice, and the fleet will.\\n\\n## Coalesce semantics\\n\\nFires are delivered only while the session is idle: a fire that comes due during an active turn is held and delivered at the next idle moment, never injected mid-turn.\\n\\nIf the scheduler slept past multiple ideal fire times (laptop closed, long-running turn, etc.), only **one** fire is delivered when it wakes up. The origin carries \`coalescedCount\` showing how many ideal fires were collapsed into this single delivery. You should treat \`coalescedCount > 1\` as \\"I missed some checks; only the latest state matters\\" rather than running the prompt that many times.\\n\\n## Cron-fire envelope\\n\\nWhen a cron task fires, the prompt you scheduled is re-injected wrapped in an XML envelope that exposes the fire context:\\n\\n\`\`\`\\n<cron-fire jobId=\\"...\\" cron=\\"...\\" recurring=\\"true|false\\" coalescedCount=\\"N\\" stale=\\"true|false\\">\\n<prompt>\\nyour original prompt text, verbatim\\n</prompt>\\n</cron-fire>\\n\`\`\`\\n\\nThe envelope is parseable. Use \`coalescedCount > 1\` to know multiple ideal fires were collapsed into a single delivery (treat as \\"only the latest state matters\\"), and \`stale=\\"true\\"\` as a cue that the task is past its 7-day threshold.\\n\\n## 7-day stale behavior\\n\\nRecurring tasks that have been alive for more than 7 days fire one\\nfinal time with \`stale: true\` on the envelope, and the system then\\nauto-deletes the task. The flag is the model's notice that this is\\nthe last delivery. If the schedule is still wanted, call \`CronCreate\`\\nagain with the same \`cron\` and \`prompt\` — that resets \`createdAt\` and\\nstarts a fresh 7-day window. One-shot tasks are never marked stale.\\n\\n## Jitter behavior\\n\\nAnti-herd jitter is applied deterministically per task id:\\n  - Recurring: ideal fire time is shifted **forward** by an offset ≤ min(10% of the cron period, 15 minutes). A \`*/5 * * * *\` task can drift up to 30s; a \`0 9 * * *\` task can drift up to 15 minutes.\\n  - One-shot: only when the ideal fire lands on \`:00\` or \`:30\` of the hour, the fire is pulled **earlier** by ≤ 90 seconds. Other minutes pass through unchanged.\\n\\n## One-shot vs recurring — when to pick which\\n\\nUse \`recurring: false\` for \\"remind me at X\\" style requests, single deadlines, \\"in N minutes do Y\\", and any task that should not repeat. Use \`recurring: true\` for periodic polling (CI status, build watchers, scheduled reports), workday rituals, and anything the user explicitly described as recurring.\\n\\n## Session lifetime\\n\\nCron tasks live in the current session. When you exit, they\\nare persisted under the session homedir; resuming the same session\\nreloads them and the scheduler resumes from each task's \`createdAt\`. Fire times that fell during the offline window are\\ncollapsed into a single delivery via \`coalescedCount\` (and recurring\\ntasks past their 7-day window arrive with \`stale: true\` as their final\\ndelivery).\\n\\nTasks do **not** carry over into a brand-new session — they are scoped\\nto the resumed session id, not to the working directory.\\n\\n## Limits\\n\\nA session holds at most 50 live cron tasks; creating one beyond that is rejected. (The \`prompt\` body is also capped — see its parameter description.) Expressions that never fire within the next 5 years (e.g. \`0 0 31 2 *\`, an impossible date) are rejected at create time.\\n\\n## Returned fields\\n\\n\`id\` (ULID), \`cron\` (the normalized expression), \`humanSchedule\` (English summary), \`recurring\`,\\n\`nextFireAt\` (local ISO timestamp with numeric offset, or null). \`id\` is needed by \`CronDelete\`.\\n\\n## Tell the user how to cancel or modify\\n\\nAfter successfully creating a task, proactively tell the user how they can cancel or modify it later. Users have no direct \`/cron\` command or self-service UI to manage reminders themselves; they must ask the model to make changes (e.g. \\"cancel my 9am reminder\\" or \\"change my daily check to 10am\\").

The subagent runs as a same-process loop instance with its own context and wire file. Delegating also keeps the bulk of intermediate file contents out of your own context — you get a conclusion back instead of a pile of dumps.\\n\\nWriting the prompt:\\n- The subagent starts with zero context — it has not seen this conversation. Brief it like a colleague who just walked into the room: state the goal, list what you already know, hand over the specifics.\\n- Lookups (read this file, run that test): put the exact path or command in the prompt. The subagent should not have to search for things you already know.\\n- Investigations (figure out X, find why Y): give the question, not prescribed steps — fixed steps become dead weight when the premise is wrong.\\n- Do not delegate understanding. If the task hinges on a file path or line number, find it yourself first and write it into the prompt.\\n\\nUsage notes:\\n- When the task continues earlier work a subagent already did, prefer resuming that agent (pass its \`resume\` id) over spawning a fresh instance — the resumed agent keeps its prior context.\\n- A subagent's result is only visible to you, not to the user. When the user needs to see what a subagent produced, summarize the relevant parts yourself in your own reply.\\n\\nWhen NOT to use Agent: skip delegation for trivial work you can do directly — reading a file whose path you already know, searching a small known set of files, or any task that takes only a step or two. Delegation has a context-handoff cost; it pays off only when the task is substantial enough to outweigh it.\\n\\nOnce a subagent is running, leave that scope to it: do not redo its searches or reads in parallel, and do not abandon it midway and finish the job manually. Both undo the context savings the delegation was meant to buy.\\n\\n\\nWhen \`run_in_background=true\`, the subagent runs detached from this turn. The completion arrives in a later turn as a synthetic user-role message containing its result — you do not need to poll, sleep, or check on its progress. Continue with other work or respond to the user. Never fabricate or predict what the result will say.\\n\\nDefault to a foreground subagent (omit \`run_in_background\`) when your next step needs its result — foreground hands the result straight back. Reach for \`run_in_background=true\` only when you have other work to do while it runs and do not need its result to proceed.

The output may be truncated if it is too long. If the command exits non-zero, the output ends with a \`Command failed with exit code: N\` line; a command killed by its timeout or interrupted by the user ends with its own message instead.\\n\\nIf \`run_in_background=true\`, the command will be started as a background task and this tool will return a task ID instead of waiting for command completion. When doing that, you must provide a short \`description\`. Background commands default to a 600s timeout and \`timeout\` is capped at 86400s; set \`disable_timeout=true\` only when the task should run without a timeout. You will be automatically notified when the task completes. After starting one, default to returning control to the user instead of immediately waiting on it. Use \`TaskOutput\` only for a non-blocking status/output snapshot — do not wait on a task you just launched, since its completion arrives automatically. Use \`TaskStop\` only if the task must be cancelled. If a human user wants to inspect background tasks themselves, point them to the background-task panel.\\n\\n**Guidelines for safety and security:**\\n- Each shell tool call will be executed in a fresh shell environment. The shell variables, current working directory changes, and the shell history is not preserved between calls. To run a command in a particular directory, pass the \`cwd\` argument (or use absolute paths) rather than relying on a \`cd\` from an earlier call.\\n- The tool call will return after the command is finished. You shall not use this tool to execute an interactive command or a command that may run forever. For possibly long-running foreground commands, set the \`timeout\` argument in seconds. Foreground commands default to 60s and allow up to 300s. When a foreground command hits its timeout it is moved to the background instead of being killed, and you will be automatically notified when it completes. The user can also move a running foreground command to the background at any time.\\n- Avoid using \`..\` to access files or directories outside of the working directory.\\n- Avoid modifying files outside of the working directory unless explicitly instructed to do so.\\n- Never run commands that require superuser privileges unless explicitly instructed to do so.\\n- Run git-mutating commands such as \`git commit\`, \`git push\`, \`git reset\`, and \`git rebase\` only when the user asks for them.\\n\\n**Guidelines for efficiency:**\\n- Use \`&&\` to chain commands that genuinely depend on each other, e.g. \`npm install && npm test\`. Independent read-only commands (separate \`git show\`, \`ls\`, or status checks) should be issued as separate parallel Bash calls in one response, not chained into a single call — chaining serializes their execution and mixes their output. Do not stitch outputs together with \`echo\` separators.\\n- Use \`;\` to run commands sequentially regardless of success/failure\\n- Use \`||\` for conditional execution (run second command only if first fails)\\n- Use pipe operations (\`|\`) and redirections (\`>\`, \`>>\`) to chain input and output between commands\\n- Always quote file paths containing spaces with double quotes (e.g., cd \\"/path with spaces/\\")\\n- Compose multi-step logic in a single call with \`if\` / \`case\` / \`for\` / \`while\` control flows.\\n- Prefer \`run_in_background=true\` for long-running builds, tests, watchers, or servers when you need the conversation to continue before the command finishes.\\n\\n**Commands available:**\\nThe following common command categories are usually available. Availability still depends on the host, so when in doubt run \`which <command>\` first to confirm a command exists before relying on it.\\n- Navigation and inspection: \`ls\`, \`pwd\`, \`cd\`, \`stat\`, \`file\`, \`du\`, \`df\`, \`tree\`\\n- File and directory management: \`cp\`, \`mv\`, \`rm\`, \`mkdir\`, \`touch\`, \`ln\`, \`chmod\`, \`chown\`\\n- Text and data processing: \`wc\`, \`sort\`, \`uniq\`, \`cut\`, \`tr\`, \`diff\`, \`xargs\`\\n- Archives and compression: \`tar\`, \`gzip\`, \`gunzip\`, \`zip\`, \`unzip\`\\n- Networking and transfer: \`curl\`, \`wget\`, \`ping\`, \`ssh\`, \`scp\`\\n- Version control: \`git\`; for GitHub-hosted work (PRs, issues, CI runs, API queries) prefer the \`gh\` CLI when installed — it carries the user's GitHub auth and can return structured JSON\\n- Process and system: \`ps\`, \`kill\`, \`top\`, \`env\`, \`date\`, \`uname\`, \`whoami\`\\n- Language and package toolchains: \`node\`, \`npm\`, \`pnpm\`, \`yarn\`, \`python\`, \`pip\` (use whichever the project actually relies on)\\n", "parameters": { "$schema": "http://json-schema.org/draft-07/schema#", "type": "object", "properties": { "command": { "type": "string", "minLength": 1, "description": "The command to execute." }, "cwd": { "description": "The working directory in which to run the command.

The origin carries \`coalescedCount\` showing how many ideal fires were collapsed into this single delivery. You should treat \`coalescedCount > 1\` as \\"I missed some checks; only the latest state matters\\" rather than running the prompt that many times.\\n\\n## Cron-fire envelope\\n\\nWhen a cron task fires, the prompt you scheduled is re-injected wrapped in an XML envelope that exposes the fire context:\\n\\n\`\`\`\\n<cron-fire jobId=\\"...\\" cron=\\"...\\" recurring=\\"true|false\\" coalescedCount=\\"N\\" stale=\\"true|false\\">\\n<prompt>\\nyour original prompt text, verbatim\\n</prompt>\\n</cron-fire>\\n\`\`\`\\n\\nThe envelope is parseable. Use \`coalescedCount > 1\` to know multiple ideal fires were collapsed into a single delivery (treat as \\"only the latest state matters\\"), and \`stale=\\"true\\"\` as a cue that the task is past its 7-day threshold.\\n\\n## 7-day stale behavior\\n\\nRecurring tasks that have been alive for more than 7 days fire one\\nfinal time with \`stale: true\` on the envelope, and the system then\\nauto-deletes the task. The flag is the model's notice that this is\\nthe last delivery. If the schedule is still wanted, call \`CronCreate\`\\nagain with the same \`cron\` and \`prompt\` — that resets \`createdAt\` and\\nstarts a fresh 7-day window. One-shot tasks are never marked stale.\\n\\n## Jitter behavior\\n\\nAnti-herd jitter is applied deterministically per task id:\\n  - Recurring: ideal fire time is shifted **forward** by an offset ≤ min(10% of the cron period, 15 minutes). A \`*/5 * * * *\` task can drift up to 30s; a \`0 9 * * *\` task can drift up to 15 minutes.\\n  - One-shot: only when the ideal fire lands on \`:00\` or \`:30\` of the hour, the fire is pulled **earlier** by ≤ 90 seconds. Other minutes pass through unchanged.\\n\\n## One-shot vs recurring — when to pick which\\n\\nUse \`recurring: false\` for \\"remind me at X\\" style requests, single deadlines, \\"in N minutes do Y\\", and any task that should not repeat. Use \`recurring: true\` for periodic polling (CI status, build watchers, scheduled reports), workday rituals, and anything the user explicitly described as recurring.\\n\\n## Session lifetime\\n\\nCron tasks live in the current session. When you exit, they\\nare persisted under the session homedir; resuming the same session\\nreloads them and the scheduler resumes from each task's \`createdAt\`. Fire times that fell during the offline window are\\ncollapsed into a single delivery via \`coalescedCount\` (and recurring\\ntasks past their 7-day window arrive with \`stale: true\` as their final\\ndelivery).\\n\\nTasks do **not** carry over into a brand-new session — they are scoped\\nto the resumed session id, not to the working directory.\\n\\n## Limits\\n\\nA session holds at most 50 live cron tasks; creating one beyond that is rejected.

If a previously blocked goal is resumed, treat the resumed run as a fresh blocked audit. If the objective itself is impossible, unsafe, or contradictory, call \`blocked\` in the same turn instead of running more goal turns. Do not use \`blocked\` because the work is large, hard, slow, uncertain, incomplete, still needs validation, would benefit from clarification, or needs more goal turns. Once the 3-turn threshold is met and you cannot make meaningful progress without user input or an external-state change, call \`blocked\` instead of leaving the goal active.\\n\\nMost active goal turns should not call this tool. If you complete one useful slice of work and material work remains, end the turn normally without calling UpdateGoal; the runtime will prompt you to continue in the next goal turn. Call \`complete\` only when all required work is done, any stated validation has passed, and there is no useful next action. Do not call \`complete\` after only producing a plan, summary, first pass, or partial result. Call \`blocked\` only after the blocked audit threshold is met. If you call \`blocked\`, you will be prompted to explain the blocker in your next message. Setting the status is the machine-readable signal; the completion summary or blocker explanation is yours to write in the following message.\\n", "parameters": { "$schema": "http://json-schema.org/draft-07/schema#", "type": "object", "properties": { "status": { "type": "string", "enum": [ "active", "complete", "blocked" ], "description": "The lifecycle status to set for the current goal.

The subagent runs as a same-process loop instance with its own context and wire file. Delegating also keeps the bulk of intermediate file contents out of your own context — you get a conclusion back instead of a pile of dumps.\\n\\nWriting the prompt:\\n- The subagent starts with zero context — it has not seen this conversation. Brief it like a colleague who just walked into the room: state the goal, list what you already know, hand over the specifics.\\n- Lookups (read this file, run that test): put the exact path or command in the prompt. The subagent should not have to search for things you already know.\\n- Investigations (figure out X, find why Y): give the question, not prescribed steps — fixed steps become dead weight when the premise is wrong.\\n- Do not delegate understanding. If the task hinges on a file path or line number, find it yourself first and write it into the prompt.\\n\\nUsage notes:\\n- When the task continues earlier work a subagent already did, prefer resuming that agent (pass its \`resume\` id) over spawning a fresh instance — the resumed agent keeps its prior context.\\n- A subagent's result is only visible to you, not to the user. When the user needs to see what a subagent produced, summarize the relevant parts yourself in your own reply.\\n- Subagents use a fixed 2-hour timeout. If one times out, resume the same agent instead of starting over.\\n\\nWhen NOT to use Agent: skip delegation for trivial work you can do directly — reading a file whose path you already know, searching a small known set of files, or any task that takes only a step or two. Delegation has a context-handoff cost; it pays off only when the task is substantial enough to outweigh it.\\n\\nOnce a subagent is running, leave that scope to it: do not redo its searches or reads in parallel, and do not abandon it midway and finish the job manually. Both undo the context savings the delegation was meant to buy.\\n\\n\\nWhen \`run_in_background=true\`, the subagent runs detached from this turn. The completion arrives in a later turn as a synthetic user-role message containing its result — you do not need to poll, sleep, or check on its progress. Continue with other work or respond to the user. Never fabricate or predict what the result will say.\\n\\nDefault to a foreground subagent (omit \`run_in_background\`) when your next step needs its result — foreground hands the result straight back. Reach for \`run_in_background=true\` only when you have other work to do while it runs and do not need its result to proceed. Never launch in the background and then immediately wait on it (by polling \`TaskOutput\`, sleeping, or otherwise): that just blocks the turn for no benefit — run it in the foreground instead.\\n\\n\\nAvailable agent types (pass via subagent_type):\\n- plan: Read-only implementation planning and architecture design. Use this agent when the parent agent needs a step-by-step implementation plan, key file identification, and architectural trade-off analysis before code changes are made.\\n  Tools: Read, ReadMediaFile, Glob, Grep, WebSearch, FetchURL\\n- coder: General software engineering agent — the only subagent type with file-editing tools; use it for any delegated task that must modify code. Use this agent for non-trivial software engineering work that may require reading files, editing code, running commands, and returning a compact but technically complete summary to the parent agent.\\n  Tools: Bash, CronCreate, CronDelete, CronList, Edit, EnterPlanMode, ExitPlanMode, Glob, Grep, Read, ReadMediaFile, Skill, TaskList, TaskOutput, TaskStop, TodoList, WaitFor, WebSearch, FetchURL, Write, mcp__*\\n- explore: Fast codebase exploration with prompt-enforced read-only behavior. Fast agent specialized for exploring codebases.

When calling this agent, specify the desired thoroughness level: \\"quick\\" for basic searches, \\"medium\\" for moderate exploration, or \\"thorough\\" for comprehensive analysis across multiple locations and naming conventions.

When doing that, you must provide a short \`description\`. Background commands default to a 600s timeout and \`timeout\` is capped at 86400s; set \`disable_timeout=true\` only when the task should run without a timeout. You will be automatically notified when the task completes. After starting one, default to returning control to the user instead of immediately waiting on it. Use \`TaskOutput\` only for a non-blocking status/output snapshot — do not wait on a task you just launched, since its completion arrives automatically. Use \`TaskStop\` only if the task must be cancelled. If a human user wants to inspect background tasks themselves, point them to the background-task panel.\\n\\n**Guidelines for safety and security:**\\n- Each shell tool call will be executed in a fresh shell environment. The shell variables, current working directory changes, and the shell history is not preserved between calls. To run a command in a particular directory, pass the \`cwd\` argument (or use absolute paths) rather than relying on a \`cd\` from an earlier call.\\n- The tool call will return after the command is finished. You shall not use this tool to execute an interactive command or a command that may run forever. For possibly long-running foreground commands, set the \`timeout\` argument in seconds. Foreground commands default to 60s and allow up to 300s. When a foreground command hits its timeout it is moved to the background instead of being killed, and you will be automatically notified when it completes. The user can also move a running foreground command to the background at any time.\\n- Avoid using \`..\` to access files or directories outside of the working directory.\\n- Avoid modifying files outside of the working directory unless explicitly instructed to do so.\\n- Never run commands that require superuser privileges unless explicitly instructed to do so.\\n- Run git-mutating commands such as \`git commit\`, \`git push\`, \`git reset\`, and \`git rebase\` only when the user asks for them.\\n\\n**Guidelines for efficiency:**\\n- Use \`&&\` to chain commands that genuinely depend on each other, e.g. \`npm install && npm test\`.

The origin carries \`coalescedCount\` showing how many ideal fires were collapsed into this single delivery. You should treat \`coalescedCount > 1\` as \\"I missed some checks; only the latest state matters\\" rather than running the prompt that many times.\\n\\n## Cron-fire envelope\\n\\nWhen a cron task fires, the prompt you scheduled is re-injected wrapped in an XML envelope that exposes the fire context:\\n\\n\`\`\`\\n<cron-fire jobId=\\"...\\" cron=\\"...\\" recurring=\\"true|false\\" coalescedCount=\\"N\\" stale=\\"true|false\\">\\n<prompt>\\nyour original prompt text, verbatim\\n</prompt>\\n</cron-fire>\\n\`\`\`\\n\\nThe envelope is parseable. Use \`coalescedCount > 1\` to know multiple ideal fires were collapsed into a single delivery (treat as \\"only the latest state matters\\"), and \`stale=\\"true\\"\` as a cue that the task is past its 7-day threshold.\\n\\n## 7-day stale behavior\\n\\nRecurring tasks that have been alive for more than 7 days fire one\\nfinal time with \`stale: true\` on the envelope, and the system then\\nauto-deletes the task. The flag is the model's notice that this is\\nthe last delivery. If the schedule is still wanted, call \`CronCreate\`\\nagain with the same \`cron\` and \`prompt\` — that resets \`createdAt\` and\\nstarts a fresh 7-day window. One-shot tasks are never marked stale.\\n\\n## Jitter behavior\\n\\nAnti-herd jitter is applied deterministically per task id:\\n  - Recurring: ideal fire time is shifted **forward** by an offset ≤ min(10% of the cron period, 15 minutes). A \`*/5 * * * *\` task can drift up to 30s; a \`0 9 * * *\` task can drift up to 15 minutes.\\n  - One-shot: only when the ideal fire lands on \`:00\` or \`:30\` of the hour, the fire is pulled **earlier** by ≤ 90 seconds. Other minutes pass through unchanged.\\n\\n## One-shot vs recurring — when to pick which\\n\\nUse \`recurring: false\` for \\"remind me at X\\" style requests, single deadlines, \\"in N minutes do Y\\", and any task that should not repeat. Use \`recurring: true\` for periodic polling (CI status, build watchers, scheduled reports), workday rituals, and anything the user explicitly described as recurring.\\n\\n## Session lifetime\\n\\nCron tasks live in the current session. When you exit, they\\nare persisted under the session homedir; resuming the same session\\nreloads them and the scheduler resumes from each task's \`createdAt\`. Fire times that fell during the offline window are\\ncollapsed into a single delivery via \`coalescedCount\` (and recurring\\ntasks past their 7-day window arrive with \`stale: true\` as their final\\ndelivery).\\n\\nTasks do **not** carry over into a brand-new session — they are scoped\\nto the resumed session id, not to the working directory.\\n\\n## Limits\\n\\nA session holds at most 50 live cron tasks; creating one beyond that is rejected.

Users have no direct \`/cron\` command or self-service UI to manage reminders themselves; they must ask the model to make changes (e.g. \\"cancel my 9am reminder\\" or \\"change my daily check to 10am\\").

The subagent runs as a same-process loop instance with its own context and wire file. Delegating also keeps the bulk of intermediate file contents out of your own context — you get a conclusion back instead of a pile of dumps.\\n\\nWriting the prompt:\\n- The subagent starts with zero context — it has not seen this conversation. Brief it like a colleague who just walked into the room: state the goal, list what you already know, hand over the specifics.\\n- Lookups (read this file, run that test): put the exact path or command in the prompt. The subagent should not have to search for things you already know.\\n- Investigations (figure out X, find why Y): give the question, not prescribed steps — fixed steps become dead weight when the premise is wrong.\\n- Do not delegate understanding. If the task hinges on a file path or line number, find it yourself first and write it into the prompt.\\n\\nUsage notes:\\n- When the task continues earlier work a subagent already did, prefer resuming that agent (pass its \`resume\` id) over spawning a fresh instance — the resumed agent keeps its prior context.\\n- A subagent's result is only visible to you, not to the user. When the user needs to see what a subagent produced, summarize the relevant parts yourself in your own reply.\\n\\nWhen NOT to use Agent: skip delegation for trivial work you can do directly — reading a file whose path you already know, searching a small known set of files, or any task that takes only a step or two. Delegation has a context-handoff cost; it pays off only when the task is substantial enough to outweigh it.\\n\\nOnce a subagent is running, leave that scope to it: do not redo its searches or reads in parallel, and do not abandon it midway and finish the job manually.

Never launch in the background and then immediately wait on it (by polling \`TaskOutput\`, sleeping, or otherwise): that just blocks the turn for no benefit — run it in the foreground instead.\\n\\n\\nAvailable agent types (pass via subagent_type):\\n- plan: Read-only implementation planning and architecture design. Use this agent when the parent agent needs a step-by-step implementation plan, key file identification, and architectural trade-off analysis before code changes are made.\\n  Tools: Read, ReadMediaFile, Glob, Grep, WebSearch, FetchURL\\n- coder: General software engineering agent — the only subagent type with file-editing tools; use it for any delegated task that must modify code. Use this agent for non-trivial software engineering work that may require reading files, editing code, running commands, and returning a compact but technically complete summary to the parent agent.\\n  Tools: Bash, CronCreate, CronDelete, CronList, Edit, EnterPlanMode, ExitPlanMode, Glob, Grep, Read, ReadMediaFile, Skill, TaskList, TaskOutput, TaskStop, TodoList, WaitFor, WebSearch, FetchURL, Write, mcp__*\\n- explore: Fast codebase exploration with prompt-enforced read-only behavior. Fast agent specialized for exploring codebases. Use this when you need to quickly find files by patterns (e.g. \\"src/**/*.yaml\\"), search code for keywords (e.g. \\"database connection\\"), or answer questions about the codebase (e.g. \\"how does the auth module work?\\"). When calling this agent, specify the desired thoroughness level: \\"quick\\" for basic searches, \\"medium\\" for moderate exploration, or \\"thorough\\" for comprehensive analysis across multiple locations and naming conventions. Use this agent for any read-only exploration that will clearly require more than 3 search queries.

When doing that, you must provide a short \`description\`. Background commands default to a 600s timeout and \`timeout\` is capped at 86400s; set \`disable_timeout=true\` only when the task should run without a timeout. You will be automatically notified when the task completes. After starting one, default to returning control to the user instead of immediately waiting on it. Use \`TaskOutput\` only for a non-blocking status/output snapshot — do not wait on a task you just launched, since its completion arrives automatically. Use \`TaskStop\` only if the task must be cancelled. If a human user wants to inspect background tasks themselves, point them to the background-task panel.\\n\\n**Guidelines for safety and security:**\\n- Each shell tool call will be executed in a fresh shell environment. The shell variables, current working directory changes, and the shell history is not preserved between calls. To run a command in a particular directory, pass the \`cwd\` argument (or use absolute paths) rather than relying on a \`cd\` from an earlier call.\\n- The tool call will return after the command is finished. You shall not use this tool to execute an interactive command or a command that may run forever. For possibly long-running foreground commands, set the \`timeout\` argument in seconds. Foreground commands default to 60s and allow up to 300s. When a foreground command hits its timeout it is moved to the background instead of being killed, and you will be automatically notified when it completes. The user can also move a running foreground command to the background at any time.\\n- Avoid using \`..\` to access files or directories outside of the working directory.\\n- Avoid modifying files outside of the working directory unless explicitly instructed to do so.\\n- Never run commands that require superuser privileges unless explicitly instructed to do so.\\n- Run git-mutating commands such as \`git commit\`, \`git push\`, \`git reset\`, and \`git rebase\` only when the user asks for them.\\n\\n**Guidelines for efficiency:**\\n- Use \`&&\` to chain commands that genuinely depend on each other, e.g. \`npm install && npm test\`. Independent read-only commands (separate \`git show\`, \`ls\`, or status checks) should be issued as separate parallel Bash calls in one response, not chained into a single call — chaining serializes their execution and mixes their output. Do not stitch outputs together with \`echo\` separators.\\n- Use \`;\` to run commands sequentially regardless of success/failure\\n- Use \`||\` for conditional execution (run second command only if first fails)\\n- Use pipe operations (\`|\`) and redirections (\`>\`, \`>>\`) to chain input and output between commands\\n- Always quote file paths containing spaces with double quotes (e.g., cd \\"/path with spaces/\\")\\n- Compose multi-step logic in a single call with \`if\` / \`case\` / \`for\` / \`while\` control flows.\\n- Prefer \`run_in_background=true\` for long-running builds, tests, watchers, or servers when you need the conversation to continue before the command finishes.\\n\\n**Commands available:**\\nThe following common command categories are usually available. Availability still depends on the host, so when in doubt run \`which <command>\` first to confirm a command exists before relying on it.\\n- Navigation and inspection: \`ls\`, \`pwd\`, \`cd\`, \`stat\`, \`file\`, \`du\`, \`df\`, \`tree\`\\n- File and directory management: \`cp\`, \`mv\`, \`rm\`, \`mkdir\`, \`touch\`, \`ln\`, \`chmod\`, \`chown\`\\n- Text and data processing: \`wc\`, \`sort\`, \`uniq\`, \`cut\`, \`tr\`, \`diff\`, \`xargs\`\\n- Archives and compression: \`tar\`, \`gzip\`, \`gunzip\`, \`zip\`, \`unzip\`\\n- Networking and transfer: \`curl\`, \`wget\`, \`ping\`, \`ssh\`, \`scp\`\\n- Version control: \`git\`; for GitHub-hosted work (PRs, issues, CI runs, API queries) prefer the \`gh\` CLI when installed — it carries the user's GitHub auth and can return structured JSON\\n- Process and system: \`ps\`, \`kill\`, \`top\`, \`env\`, \`date\`, \`uname\`, \`whoami\`\\n- Language and package toolchains: \`node\`, \`npm\`, \`pnpm\`, \`yarn\`, \`python\`, \`pip\` (use whichever the project actually relies on)\\n", "parameters": { "$schema": "http://json-schema.org/draft-07/schema#", "type": "object", "properties": { "command": { "type": "string", "minLength": 1, "description": "The command to execute." }, "cwd": { "description": "The working directory in which to run the command.

One-shot tasks are never marked stale.\\n\\n## Jitter behavior\\n\\nAnti-herd jitter is applied deterministically per task id:\\n  - Recurring: ideal fire time is shifted **forward** by an offset ≤ min(10% of the cron period, 15 minutes). A \`*/5 * * * *\` task can drift up to 30s; a \`0 9 * * *\` task can drift up to 15 minutes.\\n  - One-shot: only when the ideal fire lands on \`:00\` or \`:30\` of the hour, the fire is pulled **earlier** by ≤ 90 seconds. Other minutes pass through unchanged.\\n\\n## One-shot vs recurring — when to pick which\\n\\nUse \`recurring: false\` for \\"remind me at X\\" style requests, single deadlines, \\"in N minutes do Y\\", and any task that should not repeat. Use \`recurring: true\` for periodic polling (CI status, build watchers, scheduled reports), workday rituals, and anything the user explicitly described as recurring.\\n\\n## Session lifetime\\n\\nCron tasks live in the current session. When you exit, they\\nare persisted under the session homedir; resuming the same session\\nreloads them and the scheduler resumes from each task's \`createdAt\`. Fire times that fell during the offline window are\\ncollapsed into a single delivery via \`coalescedCount\` (and recurring\\ntasks past their 7-day window arrive with \`stale: true\` as their final\\ndelivery).\\n\\nTasks do **not** carry over into a brand-new session — they are scoped\\nto the resumed session id, not to the working directory.\\n\\n## Limits\\n\\nA session holds at most 50 live cron tasks; creating one beyond that is rejected.

A task that finished on its own with a clean exit carries neither \`stop_reason\` nor \`terminal_reason\`.\\n- The full, never-truncated log is always available at output_path; use the \`Read\` tool with that path to page through it, whether or not the preview was truncated.\\n- This tool works with the generic background task system and should remain the primary read path for future task types, not just bash.\\n", "parameters": { "$schema": "http://json-schema.org/draft-07/schema#", "type": "object", "properties": { "task_id": { "type": "string", "description": "The background task ID to inspect." } }, "required": [ "task_id" ], "additionalProperties": false } }, { "name": "TaskStop", "description": "Stop a running background task.\\n\\nOnly use this when a task must genuinely be cancelled — for a task that is\\nfinishing normally, wait for its completion notification or inspect it with\\n\`TaskOutput\` instead of stopping it.\\n\\nGuidelines:\\n- This is a general-purpose stop capability for any background task.

Subject: [PATCH 06/12] feat: delete sessions from the session picker

Ctrl+X on a row asks for confirmation and deletes the session. The
picker stays mounted and locks input while the deletion runs, so nothing
races the swap; deleting the current session closes it and starts a
fresh one, and a failed delete reattaches to the session that survived.

Subject: [PATCH 08/12] docs: cover session deletion, side-question tools, and
 subagent model prose

Document the Ctrl-X delete in the session picker, the read-only tools a
/btw side question may call, that the subagent timeout also governs tower
workers and reviewers, and how the reserved primary alias is rendered.

+- **`/sessions`** (alias `/resume`): browse and resume a previous session. Press `Ctrl-X` on a row to delete that session; the picker asks for confirmation and stays open until the deletion finishes. Deleting the session you are in closes it and starts a fresh one.
 - **`/fork`**: fork the current session (see below).
 - **`/title <text>`** (alias `/rename`): set a session title for easier identification; without arguments, displays the current title.

Subject: [PATCH 09/12] fix: address review findings on Glob chips, config
 warnings and tower missions

Count only real paths in the Glob result chip: prefer the page header's own
range when present, and ignore the diagnostic and footer lines the tool emits
around the matches.

Recompute configuration diagnostics per domain, so a persisted write or a
section registered after startup refreshes its warnings instead of leaving
stale ones until the next reload.

Require at least one non-empty task on a tower build mission; read-only survey
missions still need none. Move mission-file reads into the tower store, and
fence the author's review-request in the reviewer briefing so its text is read
as evidence and never as instructions.

Update smol-toml to a release that is not affected by GHSA-7w5x-hrqm-74c2.

Subject: [PATCH 10/12] chore: finish the brand sweep in extension release
 notes and test fixtures

Complete the identity rename in the VS Code extension changelog: the 0.6.x
blocks still carried the old product name, repository links, SDK scope, home
environment variable and setting keys that the newer entries in the same file
already use in their current form.

Drop a stale release note describing a managed OAuth provider id the product
does not ship.

Rename arbitrary model ids in the extension test fixtures to neutral
placeholders.

-- Rename the managed OAuth provider so it is named after the platform that serves it rather than reading as a first-party service: the provider id is now `managed:kimi-code`, its models are aliased `kimi-code/*`, and its credentials are stored under `oauth/kimi-code`.
 - Add an SDK routine that imports a catalog provider and its models into the persisted config, and use it for the CLI provider import so both entry points preserve existing defaults the same way.

From 31e229fd21005e2e5fd6b72e194493643b269118 Mon Sep 17 00:00:00 2001
From: elkaix <melkholy@techmatrix.com>

Subject: [PATCH 11/12] fix: clear stale config warnings and harden the
 reviewer briefing fence

Rebuild the "ignored invalid config section" warnings with each validation
pass, so a write that fixes a section clears its warning instead of leaving it
until the next reload.

Neutralize an author-account fence tag written inside a review request, so a
worker cannot close the untrusted-data block and address the reviewer directly.

Document that the subagent timeout also governs tower workers and reviewers,
and drop a leftover unused variable in the session-picker startup test.

Pass `subagent_type` to choose the profile used by every spawned subagent in the dynamic_workflow, or omit it to use `coder`. Pass `model` (available when [secondary-model routing](../configuration/config-files.md#subagent-model-pool) is enabled and a pool is configured — a `[secondary_model.models]` table or a lone `default_model`) to run item-spawned subagents on a pool alias or on the caller's own model (`"primary"`). Without it, item-spawned subagents bind the pool's `default_model`; without a configured pool, they inherit the caller's model. Resumed subagents keep their own model. Without `resume_agent_ids`, the tool requires at least 2 items; with `resume_agent_ids`, it can resume one or more existing subagents. The tool supports up to 128 total subagents, waits for all subagents to finish, and returns an aggregated report. Each subagent times out after 2 hours by default; configure the limit with [`[dynamic_workflow] timeout_ms`](../configuration/config-files.md#dynamic-workflow) in `config.toml` (`0` means no timeout) or the `PYTHINKER_CODE_AGENT_DYNAMIC_WORKFLOW_TIMEOUT_MS` environment variable. Print mode (`pythinker -p`) defaults to no timeout. A timed-out subagent is aborted and marked as failed in the aggregated report. In the TUI, foreground dynamicWorkflows show a live `Agent dynamic_workflow` progress panel above the input box. If a model response calls `AgentDynamicWorkflow`, that call must be the only tool call in the response; to run multiple dynamicWorkflows, call one `AgentDynamicWorkflow`, wait for its result, then call the next, or combine the work into one dynamic_workflow when a single template can cover it. In `manual` permission mode, `AgentDynamicWorkflow` calls outside active dynamic_workflow mode request approval unless a permission rule allows them; while dynamic_workflow mode is active, `AgentDynamicWorkflow` itself is auto-approved. Permission rules match `AgentDynamicWorkflow` by tool name only — argument patterns such as `AgentDynamicWorkflow(dynamic_workflow)` are not supported. By default the tool ramps up concurrency without an upper limit (5 subagents start immediately, then 1 more every 700 ms); set `[dynamic_workflow] max_concurrency` or `PYTHINKER_CODE_AGENT_DYNAMIC_WORKFLOW_MAX_CONCURRENCY` to a positive integer to cap how many subagents run at the same time across all execution phases. An invalid environment value makes the call fail fast.

Subject: [PATCH 12/12] fix: let the subagent timeout environment variable
 disable the timeout

`[subagent] timeout_ms = 0` already means "no timeout", and the sibling
dynamic-workflow variable accepts the same value, but the subagent environment
variable rejected `0` and silently fell back to the configured value. Accept a
non-negative integer, and ignore a blank value rather than reading it as zero.
