Git Worktree Implementation

Workflow

1. Confirm the current directory is a git repo.
2. Fetch latest refs: git fetch origin.
3. List existing worktrees: git worktree list.
4. Decide branch name.
   • If a name is provided, use it.
   • Otherwise infer naming from git branch -r and propose a name for approval.
5. Determine base branch:
   • git symbolic-ref refs/remotes/origin/HEAD | sed 's@^refs/remotes/origin/@@'
6. Create the worktree:
   • git worktree add -b <branch-name> .worktrees/<sanitized-name> origin/<base>
   • <sanitized-name> replaces / with -.
7. Offer next actions:
   • cd <worktree-path> && codex
   • Continue in current session after cd

Placement rules

• Place worktrees under <repo>/.worktrees/<branch-name>/.
• Keep .worktrees/ out of version control (add to .gitignore if needed).
