Clean up stale Git worktrees without guessing where your tools put them.

Treezap is a small CLI that starts from the directory where your main checkouts live, asks Git where each repository's registered worktrees are, and removes only linked worktrees that pass conservative safety checks.

Agent and editor workflows create worktrees in many different places. The main checkout is usually easy to find; the worktrees are not. Treezap uses Git's own worktree registry to discover them, then applies deterministic checks before deleting anything.

Run it directly with npx:

npx treezap candidates ~/code --min-age 30d

Scan the directory that contains your normal project checkouts:

npx treezap scan ~/code

Evaluate linked worktrees older than the minimum age:

npx treezap candidates ~/code --min-age 30d

The JSON includes candidates for worktrees that pass every safety check and blockedCandidates for old worktrees that need review before deletion.

Print a compact count summary:

npx treezap candidates ~/code --min-age 30d --count

deletable: 15
old_enough_blocked: 116
blocked_dirty: 31
blocked_untracked: 16
blocked_missing_default_branch: 0
blocked_unique_patches: 27

Delete eligible linked worktrees:

npx treezap rm-old ~/code --min-age 30d

Inspect one path:

npx treezap stat /path/to/worktree

Delete one eligible linked worktree:

npx treezap rm /path/to/worktree --min-age 30d

A worktree is not deleted unless it is:

• older than the minimum age
• clean, with no tracked changes
• free of untracked files
• able to identify the repository default branch
• free of unique committed patches relative to the default branch

Bulk deletion skips primary repository checkouts. It only deletes linked worktrees discovered through git worktree list.

Treezap uses refs/remotes/origin/HEAD as the default branch signal and git cherry <default-branch> HEAD to distinguish committed work that is patch-equivalent to the default branch from committed work that still has unique patches. Missing upstream metadata is diagnostic; it is not a deletion blocker when committed patches are already represented on the default branch.

--min-age accepts case-insensitive durations:

• 30d days
• 2w weeks
• 1m months, treated as 30 days
• 1y years, treated as 365 days

The default is 30d.

treezap scan <root>
treezap stat <path>
treezap candidates <root> [--min-age duration] [--count]
treezap rm <path> [--min-age duration]
treezap rm-old <root> [--min-age duration]

Command output is JSON except --help and candidates --count, so the CLI is straightforward to drive from scripts or agents.

npm test
npm run check
npm run build

The Docker fixture creates repositories and worktrees across several locations:

npm run fixture:build
npm run fixture:check
npm run fixture:shell
