muse) as a background implementer, then review its diff and
land it yourself. Use this whenever the user wants to hand implementation work to Muse — phrasings
like "have Muse do X", "delegate this to Muse", "run it through Muse", or "use Muse to
implement/fix/refactor" — or wants to run a queue of coding tasks through Muse while staying the
reviewer. Prefer it when the user will review the diff and commit it themselves. It applies only
when the user wants that separate muse exec implementer run: if you are Muse yourself and the
user simply asks you to write the code, do it directly. DO NOT USE for tasks small enough to do
inline.
license: MIT
compatibility: Requires the muse CLI installed and authenticated (muse login or META_API_KEY), Node 18+, and git. Upstream's launcher targets UNIX (macOS/Linux). The orchestrating agent must be able to run shell commands and read files. Shell examples assume bash/zsh.
metadata:
version: 0.5.0You are the orchestrator. This skill lets you hand a bounded coding task to a separate
implementer — Muse Code (muse) — then review what it produced and land it yourself. You write
the brief and own the judgment; Muse does the typing in its own exec run; you verify and commit.
Nothing here is specific to one orchestrating agent. The loop needs only the ability to run a shell command and read a file, so any agent with those two capabilities can drive it. The full delegate → review → commit loop has been run with Claude Code as the orchestrator. Other orchestrators remain unproven.
muse CLI is not installed or not authenticated (run muse login, or set META_API_KEY).muse launcher is Darwin/Linux
only; this skill still ships in the Windows contract matrix, but a live Windows dispatch is not a
supported Muse install.Headless Muse is muse exec only. muse resume is the interactive TUI and is never invoked.
--resume-last is rejected; continue a run with --session <id> (Muse's --session-id).
Write runs keep Muse's sandbox on and pass --disable-approval so a headless run cannot hang on a
tool-approval prompt. They also pass --trust-workspace and --user-input-auto-resolve. That is not
--yolo and not --full-access — do not invent either as the default. --trust-workspace loads the
target repo's rules and skills into the implementer run, and nothing in the relay narrows the
implementer's tool set inside the sandbox; the brief is what bounds it to the task.
--read-only adds --disable-write (non-shell filesystem writes) and --disable-shell. Approval
stays disabled so the review cannot block on a prompt either.
--provider echo|meta is a relay-only flag for tests and explicit probes. It is not a fleet dial.
muse --version succeeds. If not, install Muse Code and run muse login (or export META_API_KEY).muse is on PATH. command -v muse shows the active launcher. The relay records
the version it ran into result.json.--cd at) the target git repository.Muse has a configured default model, so a fresh run may omit --model. Pass --model or a fleet
--lane that sets one when you need to pin a catalog id. On a resumed --session run, omit
--model to keep the session's model. If the human has not named a usable set, ask before guessing
a metered id.
More depth: references/writing-the-brief.md.
Run these five steps per task. Steps 1, 4, and 5 are your judgment; 2 and 3 are mechanical.
Muse sees only the text you send plus what it can read from the working tree — no chat history, no shared context. Everything the task needs goes in the brief: the goal, the current state, what to change, what to leave untouched, the project's actual gate commands (discover them from the repo's AGENTS.md/CLAUDE.md/Makefile — do not assume), and a report contract. Tell Muse it will not commit (you will). Keep one task per brief. Full guidance and a template: references/writing-the-brief.md.
Send the brief to Muse with the bundled helper. It wraps muse exec --json --prompt-file, captures
the run, and writes a structured result.json. (<skill-dir> below is this skill's installed
directory — the folder containing this SKILL.md.)
node "<skill-dir>/scripts/relay.mjs" --brief brief.txt --cd /path/to/repo
# optional model: add --model <id>
# fleet lane from delegate-setup: add --lane <name> (dials apply; flags still win)
# reasoning intensity: add --effort none|minimal|low|medium|high|xhigh|max|ultra
# read-only (no non-shell writes, no shell): add --read-only
# continue a specific Muse session: add --session <id> (delta brief only; no --resume-last)
# hard time limit (watchdog): add --timeout 2h (default: off; implementation runs routinely need 1-2h)
# see all options: node .../relay.mjs --help
The helper writes artifacts to a temp dir, so the repo under review stays clean. It never commits
— see step 5. Mechanics, flags, and the result.json shape:
references/dispatch-and-poll.md.
The helper blocks until Muse finishes, so back it with whatever your orchestrator offers and resume when it returns:
run_in_background: true; you are notified on completion.result.json exists with a status. (A pre-run usage error —
bad args or an empty brief — instead exits with code 2 and writes no result file, so check the exit
code too. A missing muse binary exits 127 but does write a result.json with status
muse_unavailable. --resume-last is a usage error: headless resume is --session <id>.)Do not trust progress trackers over reality: a run is finished when result.json is written and the
process has exited. Muse can exit 0 without a run.terminal.completed event; the relay reports that
as failed, not completed. The implementer's full report is the finalMessage field in
result.json (also printed in full on stdout between the report markers).
Muse's result.json includes its own final message and any gate claims. Re-verify, don't accept:
touchedFiles in the result is your starting point.guard-skills) — this skill produces the work; those skills judge it.Full checklist: references/review-and-land.md.
The implementer edits the working tree; the orchestrator commits. Committing should be the act of the party that verified the work. Only after the gates pass and the diff holds:
--session <id> (don't restate the whole task) and
review again. There is no headless --resume-last.Delegation is something the human opts into. Once they have ("run this queue", "proceed"), committing verified, gate-passing work is the agreed contract — that is the whole point. Two limits on that mandate: surface, don't absorb (report Muse's design decisions, defensible-but-unasked turns, and non-blocking nitpicks rather than silently keeping them) and stop for scope changes (if correct completion needs going beyond the brief, ask — don't expand the mandate yourself). The full treatment is in references/review-and-land.md.
