Conciseness

The body is lean and assumes Claude's competence — no tutorial explanation of what worktrees are — with every section carrying operational content. It could be tightened: the Overview repeats the frontmatter description nearly verbatim, and the Validation Checklist overlaps the Operational Checklist's After Creation items. Efficient with minor trimmable redundancy, matching the 4 anchor rather than the fully lean 5.

Actionability

Commands are copy-paste ready and complete, e.g. 'python scripts/worktree_manager.py --repo . --branch feature/new-auth --name wt-auth --base-branch main --install-deps --format text' and both stdin and '--input file' JSON variants, plus concrete cleanup invocations with flags. Specific examples cover the creation, parallel-run, and cleanup cases.

Workflow Clarity

Multi-step workflows are numbered and paired with explicit validation checkpoints ('Validation Checklist', 'Before Creation / After Creation / Before Removal') and a Failure Recovery section giving feedback loops (e.g. 'If port allocation collides with external service: rerun with adjusted base ports'). The destructive cleanup workflow is guarded by dirty-state and merged-branch checks with a 'remove only merged + clean' rule and a never-force-dirty caveat, so the destructive-operation cap does not apply.

Progressive Disclosure

References are clearly signaled and one level deep ('See [port-allocation-strategy.md](references/port-allocation-strategy.md) for the full strategy and edge cases'), but none of the referenced files — references/*.md, scripts/worktree_manager.py, scripts/worktree_cleanup.py, or README.md — exist in the bundle, so the promised navigation is broken. Not 4, because the split depends on files that are missing; not 2, because the in-body structure and reference signaling are genuinely good.

Specificity

The description lists multiple concrete actions — 'Run parallel feature work safely with Git worktrees', 'Standardizes branch isolation, port allocation, environment sync, and cleanup' — giving comprehensive coverage of the skill's capabilities without padding. It is written in third person ('Run', 'Standardizes'), so no voice penalty applies.

Completeness

It explicitly answers both what ('Run parallel feature work... Standardizes branch isolation, port allocation, environment sync, and cleanup so each worktree behaves like an independent local app') and when ('Use when running multiple feature branches simultaneously, isolating experimental work, or coordinating multi-agent development across the same repo') with concrete trigger phrases. Not 4, because the 'when' clause is explicit and enumerates specific scenarios rather than being generic.

Trigger Term Quality

Natural phrases like 'Git worktrees', 'running multiple feature branches simultaneously', 'isolating experimental work', and 'coordinating multi-agent development' match what users would actually say, but a few natural variations (e.g., 'parallel development', 'hotfix branches') are missing. This sits between 'good keyword coverage' (4) and 'comprehensive coverage with synonyms' (5), closer to 4.

Distinctiveness Conflict Risk

It carves a clear niche — Git worktree parallelism with port/environment isolation for multi-agent workflows — with triggers ('worktrees', 'multiple feature branches simultaneously') that are unlikely to fire for unrelated skills. Not 4, because there is no meaningful overlap with adjacent skills; the trigger terms are distinct.
