The body assumes Claude's competence — it never explains git/worktree concepts — and every section earns its place; the repeated 'cd <main-working-tree> &&' chaining rule is deliberate safety emphasis for a footgun rather than filler, matching the lean score-3 anchor and staying above the score-2 'could be tightened' bar.

Every step gives fully executable, copy-paste-ready commands with concrete flags (e.g. 'git -C <worktree-path> status --porcelain', 'gh pr list --head <branch-name> --state open --json number --jq length'), matching the score-3 anchor with no pseudocode or missing details that would drop it to score 2.

Steps 1–5 form a clear sequence with explicit validation checkpoints (uncommitted-change check, open-PR check before branch deletion) and a 'Recovery: Dead CWD' feedback loop, plus a Red Flags Never/Always checklist — matching the score-3 anchor for destructive operations rather than the checkpoint-gap score 2.

As a single-file skill with no bundle files, it is well-organized into clear sections (Overview, Process, Red Flags, Quick Reference, Integration) with easy navigation and nothing that obviously belongs in a separate file, satisfying the well-organized-sections path to score 3 rather than the inline-bloat score 2.

Lists multiple specific concrete actions — 'Removes git worktrees safely, cleans up associated branches, and pulls latest mainline' plus 'Checks for uncommitted changes, verifies no open PRs before branch deletion, and handles force-removal of locked worktrees' — matching the score-3 anchor for comprehensive concrete actions, not the partial coverage of score 2.

It explicitly answers both 'what' (removes worktrees, cleans branches, pulls mainline) and 'when' via a detailed 'Use when...' clause with explicit triggers, matching the score-3 anchor; it is not score 2 because the 'when' is explicit rather than missing or implied.

The 'Use when finished with a worktree, done with a branch, cleaning up after a merge or PR, abandoning work in a worktree, or when git worktree list shows stale entries' clause covers natural phrasings a user would actually say, satisfying the score-3 anchor rather than the incomplete keyword coverage of score 2.

It occupies a clear niche — worktree cleanup — with distinct triggers like 'git worktree list shows stale entries', making it unlikely to fire for unrelated git skills, matching the score-3 anchor rather than the overlap-prone score 2.
