Which Git hosting platforms are supported?

Prune Worktrees supports both GitHub and GitLab. it automatically detects which platform you are using based on your remote origin URL and uses the 'gh' or 'glab' CLI accordingly.

Can this skill accidentally delete my main repository folder?

No, the logic specifically skips the main worktree (the primary checkout) and only evaluates additional worktrees created via 'git worktree add'.

Does this skill delete my worktrees automatically?

No, the skill is designed with a safety-first approach. it performs a check, lists the worktrees safe for removal, and always requires your explicit confirmation before deleting anything.

What happens if I have uncommitted changes in a worktree?

The skill runs a 'git status' check on every worktree. If uncommitted changes are detected, the worktree is flagged as 'Dirty' and the skill will warn you to review it rather than suggesting it for safe removal.

Developer Tools

Cleans up Git worktrees associated with merged GitLab or GitHub branches to reclaim disk space and organize your workspace.

The Prune Worktrees skill automates the identification and removal of stale Git worktrees by cross-referencing local checkouts with remote merge status. It integrates seamlessly with GitLab (glab) and GitHub (gh) CLIs to detect which feature branches have already been merged into the main codebase. Designed with safety in mind, the skill identifies 'dirty' worktrees with uncommitted changes, skips the primary repository checkout, and requires explicit user confirmation before any deletion occurs, making it an essential utility for developers managing high-velocity git workflows.
