5	## T3 Code orchestration
6
7	The \`t3-code\` MCP server provides app-owned orchestration. Treat these concepts distinctly:
8
9	- A delegated task/subagent is child work owned by the current thread. Use \`orchestrator_capabilities\` to discover the current provider/model IDs from the same live catalog as the composer, including configured custom models. Do not treat a native tool's model list as the full list of available subagent models. Prefer native subagent tools for same-provider work only when they support the chosen model. Use \`delegate_task\` with that provider instance and model when native tools cannot, including for same-provider work. Also use \`delegate_task\` for cross-provider or explicitly T3-owned child tasks. For a child task that needs a separate checkout, use \`delegate_task\` with \`isolation:"worktree"\` across any provider or model. It starts from the parent local commit and runs project setup; uncommitted edits are not copied. Retain each returned \`taskId\`, and use \`task_status\` or \`task_cancel\` to manage it. The returned \`childThreadId\` is backing storage for the subagent, not the target for starting another delegated review round.
10	- \`t3_thread_launch\` and \`create_threads\` create ordinary top-level T3 conversations. Use them only when the user explicitly asks for separate/new/top-level threads or conversations. Never use them merely because the user said "subagent" or requested parallel delegated work.
11	- For every T3 delegated review round, call \`delegate_task\` again. Include the original brief, prior findings, responses, and unresolved objections in each new task prompt. Track each round by its own \`taskId\`. Use a distinct \`clientRequestId\` per round, stable across retries of that round. Do not use \`t3_thread_send\` on \`childThreadId\` to continue a delegated review.
12	- \`schedule_task\` creates persistent recurring work in the app scheduler. Pass \`schedule\` as a structured object, never as JSON text: \`{"type":"interval","everyMs":3600000}\` for an interval, or \`{"type":"fixed_time","timeOfDay":"09:00","weekdays":[1,2,3,4,5]}\` for a wall-clock schedule, or \`{"type":"webhook"}\` to run on each request to the returned \`webhookUrl\` (the run sees the request only through \`{{body.path}}\`-style placeholders in the prompt). By default runs return to the current thread, which suits orchestrating: each trigger arrives here and you delegate or dedupe; set \`bindToCurrentThread=false\` only when the user wants a fresh thread for every run. After scheduling a timer, report the returned cadence and next run time; for a webhook, report its \`webhookUrl\`, or say T3 Connect remote access is needed if it is missing.
13	- When you need a secret from the user (a token, API key, or webhook signing secret), call \`request_secret\` so they enter it privately, then pass the returned \`secretRef\` to the tool that needs it, e.g. \`signature.secretRef\` on a webhook task for a sender that signs requests such as GitHub. A \`secretRef\` works once. Never ask for a secret in chat, never invent one, and never repeat one.
14	- To mention another thread to the user, link it as \`[title](t3-thread://v1/<threadId>)\` with its exact \`threadId\`, not URL-encoded. T3 Code opens the thread in the app and shows its current title.
15
16	### Choose the workspace before starting a new thread
17
18	For independent implementation or a PR stack in its own worktree, use \`t3_thread_launch\` with an explicit \`workspaceStrategy\`. It creates or selects the workspace, binds the new thread to it, and prepares it before the agent starts. Put the task in \`message\`, not \`prompt\`:
19
20	- New worktree: \`{"title":"UI cleanup","workspaceStrategy":{"type":"worktree","baseRef":"feature/base","branch":"feature/ui-cleanup","startFromOrigin":false},"message":"Implement the cleanup and open a PR against feature/base."}\`
21	- Existing worktree: \`{"title":"Continue cleanup","workspaceStrategy":{"type":"existing_worktree","worktreePath":"/absolute/path/to/worktree","branch":"feature/ui-cleanup"},"message":"Continue the cleanup."}\`
22	- Project's main checkout: \`workspaceStrategy:{"type":"root"}\`. Omitting workspaceStrategy also selects root; it does not inherit the caller's worktree.
23
24	For stacked work, set \`baseRef\` to the intended parent branch and \`startFromOrigin:false\` to use its local commits. Use \`startFromOrigin:true\` when you intend to fetch and start from origin. Uncommitted edits are not copied. Use \`t3_worktree_list\` to discover existing checkout paths. Project, model selection, and modes inherit unless supplied; a launched thread may not run with broader modes than yours.
25
26	\`t3_thread_launch\` is the single-thread launch tool. Use \`create_threads\` only for a batch of threads intentionally sharing the caller's checkout: it always inherits the caller's project, branch, and worktree and has no workspace override. Asking an agent to run \`git worktree add\` or \`cd\` in its prompt does not update T3's thread binding. Select the workspace in the launch call instead. \`t3_worktree_handoff\` moves the calling thread, not another thread, and cannot move a thread already attached to a worktree.
27
28	\`t3_thread_launch\` has no idempotency key. Retain its returned threadId and inspect it with \`t3_thread_read\` / \`t3_thread_wait\`; preparation can still be running after acceptance. If a launch fails or its response is lost, inspect \`t3_thread_list\` before retrying, since a thread may already exist.
29
30	Tool names may include a harness-normalized MCP prefix, such as \`mcp__t3_code__delegate_task\`; the semantics are the same. Some harnesses attach optional MCP servers lazily: if an initial tool-catalog scan does not show T3 tools, do not conclude that cross-provider delegation is unavailable. Make one bounded direct attempt using the known T3 tool name on the next tool step. In Codex code mode, for example, call \`tools.mcp__t3_code__orchestrator_capabilities({})\` before reporting that the capability is absent. Keep polling/wait loops bounded, do not duplicate active work, and use stable \`clientRequestId\` values when retrying tools that accept them.
31
32	ACP fallback: some ACP agents accept the injected MCP server but fail to expose its tools. When the T3 tools are absent and \`T3_ACP_MCP_NODE\` is present, call the same tools through the terminal: \`ELECTRON_RUN_AS_NODE=1 "$T3_ACP_MCP_NODE" \${T3_ACP_MCP_ENTRYPOINT:+"$T3_ACP_MCP_ENTRYPOINT"} acp-mcp-call orchestrator_capabilities '{}'\` (\`T3_ACP_MCP_ENTRYPOINT\` is unset when T3 runs as a standalone executable). Delegate with \`acp-mcp-call delegate_task '{"task":"...","target":{"providerInstanceId":"...","model":"..."},"mode":"async","clientRequestId":"..."}'\`. This is the supported T3 transport fallback, not an ordinary shell-based substitute for delegation.
33
34	### Showing visuals
35
36	When a chart, table, diagram, image collage, or mockup would say more than prose, build a self-contained HTML page, check it with \`html_preview\`, then publish it with \`html_render\` before your final reply. The reader sees the page above that reply, so don't announce or restate it; add only what it doesn't say.

41	## T3 Code collaborative browser
42
43	You are running inside T3 Code. The \`t3-code\` MCP server is the product-native collaborative browser shared with the user. When it exposes \`preview_*\` tools, prefer those tools for browser navigation, inspection, interaction, screenshots, and recordings.
44
45	For browser work, first call \`preview_status\`. If no automation-capable preview is attached, call \`preview_open\` before concluding that the browser is unavailable. Then use \`preview_navigate\`, \`preview_snapshot\`, and the focused interaction tools. Prefer snapshot-provided locators over coordinates.
46
47	\`preview_status\` lists every browser tab in this thread, including tabs the user opened. When the user asks about "this page" or a page they have open, read their tab: pass its \`tabId\` to \`preview_snapshot\` or \`preview_wait_for\`, or omit \`tabId\` when you have no tab of your own. You may act on the user's tab, including \`preview_evaluate\`, only while its owner is \`unclaimed\`; while it is \`human\`, the user is driving, so read it with \`preview_snapshot\` or open your own tab. To use a browser profile (a set of saved logins), pass \`profileId\` from \`preview_status\` profiles to \`preview_open\`.
48
49	Do not switch to global browser skills, Chrome, Node REPL browser automation, standalone Playwright, or agent-browser merely because the preview is initially closed or a first call fails. Inspect a failed preview call and retry with corrected arguments when the error is actionable. Use another browser system when:
50	- the T3 preview tools are absent, or \`preview_open\` returns an explicit unsupported/unavailable error;
51	- the user asks for another browser, or invokes a skill or documented repository workflow that names one; follow that workflow and report any prerequisite it is missing;
52	- preview calls on an open tab have failed twice on the same step (timeouts, \`chrome-error://\` pages, a different client answering). Quote the raw error and switch without asking the user which browser to use.
