Muse Code plugin for Claude Code

Use Meta's Muse Code from inside Claude Code: ask it for a review, hand it a task, or move a Claude session over to it.

Reviews and delegated work run as background jobs you can check on, stop, or resume, so a long Muse run does not hold up the Claude session that started it.

The demo is one real session against Muse Code 1.3.0, captured command by command into docs/demo-captures/. The repository path and home directory are substituted when the demo is built, and the login email is redacted in the capture files. npm run build-demo-script turns the captures into docs/demo-script.json and npm run render-demo draws it.

Everything these commands send (diffs, prompts, transcripts) goes to Meta's hosted model through your Muse login, the same as when you run Muse yourself.

Commands

• /muse:review: read-only review of your working tree or branch
• /muse:critique: a harsher review of the design, with findings returned as structured JSON
• /muse:delegate: hand a task to Muse through the muse:muse-delegate subagent, which Claude may also reach for on its own when a debugging or implementation job is large
• /muse:transfer: continue the current Claude session in Muse
• /muse:runs, /muse:show, /muse:stop: background runs
• /muse:check: setup check; also switches the stop-time review gate on or off
• /muse:sync-skills: import your Claude Code skills into Muse

Some of this comes straight from Muse rather than from the bridge: --worktree delegation, --image attachments, and critique findings that Muse enforces with --output-schema. Session transfer uses Muse's bundled resume-claude skill.

Requirements

• Muse Code, installed and logged in (muse login or META_API_KEY). Runs count against your Muse usage.
• Node.js 20 or later on the machine running Claude Code (CI runs 20 and 22).
• Git on PATH.

Muse installs with curl https://dev.meta.ai/install.sh | bash on macOS and Linux, or irm https://dev.meta.ai/install.ps1 | iex on Windows. The plugin runs muse where Claude Code runs; if you keep Muse inside WSL, run Claude Code there too (see [Windows
