Worktrees - Claude Code
Isolated git worktrees for parallel Claude Code sessions.
Git worktrees let you run multiple Claude Code sessions against the same repo on different branches without stomping on each other.
What it does
A worktree is a second checkout of the same repo, pointing at a different branch. Claude Code's EnterWorktree tool creates one, runs tasks in it, and exits back to the main checkout when done. Each session has its own working directory, its own branch, and its own in-flight changes - but shares the git object store.
When to use it
- Running two or three agents in parallel on different features.
- Keeping a clean main checkout while Claude experiments in a branch.
- Reviewing a PR in isolation without stashing.
- Dogfooding branch-heavy workflows like stacked PRs.
Gotchas
- Some tools (node_modules, build artifacts) need a separate install in each worktree.
- Hooks that assume a single working directory may misfire. Check your SessionStart scripts.
- Cleaning up abandoned worktrees takes an explicit prune - they're not garbage-collected.
