30. The parallel coding crew

The job: You have a repo, a bug list, and no patience for boilerplate. Muse Code (beta for macOS and Linux) runs persistent coding agents in separate worktrees — several tasks in flight at once, with a replay-exact event log of everything it did.

In [repo path]: fix [the flaky checkout test] and add [input validation to the signup form]. Work on each in a separate worktree, run the test suite after every change, and summarize the diff for my review. Do not push, merge, or deploy anything — changes stay local until I approve.

Difficulty Advanced · Best for Developers with bug backlogs · Solo founders · Code reviewers

What Muse will do:

  1. Fix each task in a separate worktree
  2. Run the test suite after every change
  3. Summarize the diff for your review
  4. Keep everything local — no push, merge, or deploy without approval

Why it works: separate worktrees mean parallel agents never step on each other's changes, and the event log lets you replay exactly what happened. You stop writing code and start reviewing it.

Common failures:

  • Two agents in one worktree overwrite each other — one worktree per task, no exceptions
  • Vague task descriptions produce vague diffs — scope each worktree task tightly before launching
  • Skim-reviewing the diff defeats the purpose — the event log is only useful if you actually read it

Prompt variations:

  • Launch one agent per backlog bug on Monday morning, review the whole batch by lunch
  • Add 'write the failing test first' to the prompt for test-driven tasks
