One-shot convenience: resolve canonical inbox + arm long-poll subscription. Per PR #2 (CCR server-side auto-arm) — IDE-agnostic relay-arrival arming. This is the RECOMMENDED entry point for SessionStart auto-arming across all MCP clients (Claude Code, Antigravity, Cursor, Windsurf, etc.). Equivalent to: 1. resolve_canonical_inbox_name(role) → canonical inbox name 2. nucleus_relay_subscribe(inbox_filter=<canonical>, timeout_seconds=...) Why this exists vs nucleus_relay_subscribe + inbox_filter: nucleus_relay_subscribe + inbox_filter requires the caller to KNOW the canonical inbox name for their role. nucleus_ccr_arm hides that step. Agent just calls nucleus_ccr_arm() with no args; server detects role from CC_SESSION_ROLE / NUCLEUS_SESSION_ROLE env OR detect_session_role().

Hand a coding or review task to a cross-vendor lane — a cheap, non-Claude agent that does the work for you. Use this INSTEAD OF shelling out to any CLI: it picks the vendor, injects the correct per-vendor permission flags, captures all output synchronously, and reports a real status. Do NOT run `agy`/`devin` yourself in Bash — the raw CLIs take DIFFERENT per-vendor flags (pass the wrong one and a build silently makes ZERO edits yet exits 0), and hand-driven background calls flush output late (a finished call looks empty for tens of seconds). This tool is the only robust path. First call `list` — it needs no setup, confirms cross-vendor is enabled, and shows each vendor's selectable_models + default_model. If dispatch/review return a disabled error, cross-vendor is OFF: run `nucleus onboard` once (one-time), then retry. Actions: dispatch - Hand a task to a cross-vendor lane. params: {vendor, prompt, artifact_ref, mode?, model?, expect_paths?, to?} REQUIRED: vendor ∈ 'agy'|'devin', prompt, artifact_ref. mode ∈ 'write'|'read' (default 'write'): write = the vendor CHANGES things (edit files, run commands, build/fix). read = the vendor only LOOKS and REPORTS (analyze/summarize); no file changes. When unsure use 'write': a read task still works in write mode, but a write task silently does NOTHING in read mode. model? — optional. Defaults to the vendor's verified model (agy → gemini-3.1-pro-high, devin → glm-5.2). These are ALREADY the defaults, so omitting model is sufficient; pass it only to be explicit or to override. The response echoes model_id — read model_id (NOT model_family) to confirm which model ran. A cross-wired model (e.g. glm-5.2 with agy) is rejected with the valid ids named. artifact_ref — a commit SHA / PR# / file path to bind the result to. No commit yet (a from-scratch build)? Pass the repo-relative path you will write, e.g. src/foo.py. expect_paths? — optional list of file paths you expect the vendor to change. If you pass them and the vendor changes none, status comes back NOT success ("no_files_touched") even if it narrated success. Without expect_paths, success means only that the vendor produced output — not that it edited anything, so ALWAYS confirm with your own `git diff`. (Paths are checked in the nucleus server process's working dir; pass paths valid there.) You never pass CLI flags — the tool injects the right permissions per vendor. Example (build): action="dispatch", params={"vendor":"devin","prompt":"<task>", "artifact_ref":"src/foo.py","mode":"write","model":"glm-5.2", "expect_paths":["src/foo.py"]} review - Independent, different-model verdict on pasted code / a diff. params: {content, ref?, vendor?, model?, to?} content REQUIRED (paste the code/diff inline). Default vendor agy (Gemini, model gemini-3.1-pro-high) — a genuinely different model from the devin/GLM builder, so the review is diverse. Read-only, edits nothing. Returns a terse two-line verdict. For a devin/GLM second opinion pass vendor='devin'. Example: action="review", params={"content":"<code or diff>", "model":"gemini-3.1-pro-high"} list - Show vendors, their selectable_models + default_model, the mode vocabulary, and whether cross-vendor is enabled. Needs no setup — call it first. A green result is a hypothesis until you verify it on your own shell (zero-trust). Read the response's `status` and `success`: 'ok' = produced output; 'empty_output' / 'no_files_touched' / 'timed_out' / 'error' come back success=false — NOT done. (If NUCLEUS_ENVELOPE is on, gate on the INNER success flag, not the envelope's ok.) Two caveats from real use: - SECRET HYGIENE: vendor OUTPUT is best-effort secret-redacted (Bearer/JWT/API-key patterns -> <REDACTED>; the count is in the response `redacted` field). This is a BACKSTOP, not a guarantee — never put credentials in a prompt, and the tool CANNOT scrub a file the vendor writes itself, so review any vendor file-writes near secrets yourself before trusting them. - REVIEW SEES ONLY WHAT YOU PASTE: 'review' (and 'dispatch') cannot read the repo, a diff, or any file — they judge only the text in your params. Paste the real code/diff or the reviewer will confidently critique things it cannot see. For a whole PR, paste the actual diff, not a description of it.

Report friction/bugs/enhancements to the nucleus team. WHEN TO USE: when the lane misbehaves, a task fails unexpectedly, the SPEC.md format is confusing, or you have an improvement idea. Creates a GitHub issue on the public nucleus-mcp repo (cross-machine visible) AND stores locally. Requires gh CLI auth'd.

Set up an autonomous task-execution loop in a git repo. WHEN TO USE: you have a list of tasks (bugs, features, tests) you want executed automatically without manual prompting — the lane runs watcher/executor/secretary daemons that claim tasks, invoke an LLM to implement them, and independently verify the results. Use this when you want to batch-execute a backlog of well-defined tasks. Creates .brain/, SPEC.md template, and pins via git tag.

Start autonomous lane daemons (watcher + executor + secretary) in background. WHEN TO USE: after nucleus_lane_init and SPEC.md is written — this launches the loop that autonomously claims and executes tasks. The executor invokes an LLM CLI (devin/agy) per task; the secretary independently verifies each result. Runs until nucleus_lane_stop is called.

Check lane status: task counts (PENDING/IN_PROGRESS/DONE/CONFIRMED), daemon health, spec verification. WHEN TO USE: after starting a lane to monitor progress, or before starting to check if a lane is already running.

Stop all running lane daemons. WHEN TO USE: when all tasks are CONFIRMED or you want to pause autonomous execution.

Get the next unread relay message. One call — returns full message body and auto-acks. Long-poll (60s timeout). This is the agent's idle loop. Call it, get a message or None, act or re-call. No separate inbox + ack dance. The agent's loop: 1. nucleus_next_message() → blocks up to 60s for a message 2. If message: handle it (execute task, respond to comment, etc.) 3. Re-call nucleus_next_message() — always re-arm, never sit idle 4. Never stop the loop Role is auto-detected from posture (.brain/posture/current.json). No args needed. Returns: dict with: message: full relay message (id, from, subject, body, priority, task_id) or None acked: True if message was auto-acked waited_seconds: how long the poll ran

Satellite view, commitments, loops, patterns & metrics. Actions: satellite - Unified satellite view. params: {detail_level?} scan_commitments - Scan artifacts for new commitments archive_stale - Auto-archive commitments older than 30 days export - Export brain to zip list_commitments - List open commitments. params: {tier?} close_commitment - Close a commitment. params: {commitment_id, method} commitment_health - Get commitment health summary open_loops - View all open loops. params: {type_filter?, tier_filter?} add_loop - Add a new open loop. params: {description, loop_type?, priority?} weekly_challenge - Manage weekly challenge. params: {action?, challenge_id?} patterns - Manage learned patterns. params: {action?} metrics - Get coordination metrics pr_watch - Enumerate stale PRs (>N days), classify (auto-mergeable / billing-stuck / needs-verdict), fire one relay per stale PR to the integration coord. params: {threshold_days?, dry_run?}

Execute a plan file autonomously. WHEN TO USE: you have a plan file (.brain/plans/*.md) you want executed autonomously — parses the plan, creates tasks, starts a mission with budget/time limits. Chains import_plan_as_tasks() then _brain_start_mission_impl() and returns the mission status string.

Import a plan file as PENDING tasks without starting a mission. WHEN TO USE: you have a plan file (.brain/plans/*.md) you want loaded into the task store so the executor daemon / sprint mission can pick the tasks up later — but you don't want to start a mission right now.

List available plan files in .brain/plans with task counts. WHEN TO USE: you want to discover which plan files exist and how many tasks each contains before importing or executing one. Returns: JSON string: a list of dicts each with ``{"name", "path", "size_bytes", "task_count", "format"}``. Missing directory returns ``[]``.

Relay-substrate facade — post / read / ack / status. Actions: post - Send a relay envelope. params: {to, subject, body, sender?, priority?, in_reply_to?, context?, id?, from_session_id?} sender? auto-fills from your session role when omitted. to accepts short role aliases: main, peer, tb, ops, agy, board. "recipient" is accepted as an alias for "to". Returns {sent: bool, id: str (server message_id), error?: str}. inbox - List inbox messages. params: {role?, unread_only?, limit?} role auto-fills from CC_SESSION_ROLE env. Returns {messages: [...], role: str}. ack - Mark messages seen. params: {message_ids: [str], role?} Returns {acked: int, failed: int}. status - Diagnostic (no server call). params: {role?} Returns {is_http_mode, relay_url_set, bearer_set, canonical_role, resolved_inbox_dir}. Bearer resolves per-role at call-time (~/.tb/relay_token_<role>, falling back to NUCLEUS_RELAY_BEARER env) — never passed via this tool's prompt surface. Per ADR-0036 amendment c068abc1 + v0.2.1 Layer A.

Long-poll subscription that pushes ctx.info() on each new inbox file. Replaces bash polling daemons (watch-relay-*.sh) with server-initiated push. Call once at session start (e.g. via SessionStart hook). Server holds the subscription, watches the calling agent's role-specific inbox dir, and fires info-level notifications on each new relay file arrival. Client re-calls this in a loop for persistent coverage. Per PR #1 (CCR-inversion-for-relay-pickup): `inbox_filter` parameter added to BYPASS role-based dir resolution. Use when role detection is unreliable OR when subscribing to a specific canonical inbox (e.g., 'cc_tb'). Closes 3-week-old feedback_relay_arrival_invisible_midsession HARD RULE.

W5 tier routing — route a prompt to the optimal model tier. Actions: route - Route a prompt to cheapest capable model. params: {prompt, complexity?, context?, estimated_output_tokens?} complexity ∈ 'routine' | 'complex' | 'sovereign' (default 'routine') Returns: provider, model, cost estimates, sovereignty tier.

Quick scan for a PENDING task. Returns the task directly if one is available, or None if no task is ready within the timeout. Default timeout is 5s (non-blocking). The agent should NOT loop on this — tasks arrive via relay push. This is a fallback for when the agent wants to check for tasks without waiting for a relay. No args needed — the role is auto-detected from posture (.brain/posture/current.json) or NUCLEUS_AGENT_ROLES env var.
