Muse Code workflows: parallel child agents with a control room
At a glance
Official Muse Code docs: request a workflow to fan out up to 1,000 child tasks (active cap ~16) for audits, migrations, or research→verify→synthesize. `/workflows` control room cancel/pause/skip; save reusable JS under `.agents/workflows/` via `muse workflows save`; settings auto|explicit|off. Note: some Apple silicon builds omit the workflow engine. This workflow is listed under Meta-Muse, Muse-Code, multi-agent, workflows, devtools, HITL.
Official Muse Code cookbook: four built-in playbooks load only on the turn you invoke them. /plan grounds a decision-complete plan and stops for approval; /grilling and /grill-with-docs pressure-test designs (optionally writing ADRs); /taste strips AI-slop UI defaults. Explicit-invocation only—won’t auto-plan ordinary implement requests.
Meta’s Muse Code co-trained agent (with Muse Spark) fans work out automatically: parent spawns write-capable children, each in its own git worktree so parallel edits never collide; background observer agents stay live for memory/skill/goal/verification. Fully auditable event log; workers + reviewers by default. Install: curl -fsSL https://dev.meta.ai/install.sh | bash.
Muse Code journals sessions to an append-only event log. Author a focused golden fixture (records + expected_model_context), then `muse trace inspect --fixture` replays projection with no model, tools, or network. Gate merges on zero diffs via replay_gate.sh / GitHub Actions—catch harness drift before it ships.
Helicon is a free MIT desktop (and browser) client for Meta’s Muse Code CLI: project sidebars, session history, inline diffs, approval queue and cost meter at published API rates—on the Muse Code login you already have. Native Windows (no WSL required), universal macOS DMG, Linux AppImage/source; not affiliated with Meta. Fills the “GUI for Muse Code” gap while Meta ships TUI-first.
