Zen

zen
Review PRs and ship features in parallel — each one in its own Claude-ready worktree.

You're reviewing more PRs and starting more features than ever, because Claude Code makes each one faster. But your IDE and your shell still want one branch at a time. Zen fixes that mismatch.

For every PR in your review queue and every feature you're working on, zen creates a dedicated git worktree with Claude pre-armed: PR context injected as CLAUDE.local.md (never touching the repo's own CLAUDE.md), the right slash command installed, terminal tab opened on demand. A background daemon watches GitHub, prepares review worktrees silently as PRs come in, fast-forwards them when the PR head moves, and removes them a few days after merge. Open a tab when you're ready — everything is already set up.

Quick start

- Alternatively, skip mv zen ~/bin and install with Nix.

When a PR shows up in your inbox, zen review  opens that PR in a new terminal tab with Claude pre-armed and the PR context loaded. See Prerequisites for what to install first.

What needs your attention?

zen inbox is your daily triage. Three classes of PRs land here:

- Reviews waiting on you — PRs from configured authors, plus any explicit review requests.
- Your own approved-but-unmerged PRs — signed off, ready to land.
- Open PRs touching paths you watch — for staying aware of areas you care about.

Drafts are shown by default. To skip drafts permanently, set ignore_drafts: true in your config — see docs/configuration.md. The --ignore-drafts flag overrides the config for a single run.
