Conciseness

The body is lean and assumes Claude's git competence — no explanation of what commits or hooks are, every guideline is a guardrail. Two minor instances could be trimmed: the opening paragraph restates the frontmatter description, and 'Construct the git commit command with the generated message. Execute the commit:' is redundant phrasing. That matches the 'minor instances of over-explanation' anchor rather than perfect leanness.

Actionability

Fully executable, copy-paste-ready commands at every step: 'git log --oneline -20', 'git status --short', 'git diff --cached', 'git commit -m "<subject>" -m "<body>"', plus explicit handling rules for staged vs unstaged changes and hook outcomes. Specific and complete for the common cases.

Workflow Clarity

A clearly sequenced 5-step workflow with explicit validation checkpoints: the stop condition on a clean tree, post-commit verification via 'git status --short' and 'git log --oneline -1', and an explicit error-recovery path for pre-commit hooks ('do not amend automatically. Tell the user what changed and ask...'). Feedback loops are present, so the destructive-operation cap does not apply.

Progressive Disclosure

No bundle files exist (references/scripts/assets absent), and none are needed: this is a single-purpose skill whose content fits comfortably in one file, organized into a Guidelines section and a numbered Workflow with clear headers. Structure and placement are appropriate with no buried or inlined-overflow content.

Specificity

Concrete actions are stated in third person — 'Commit staged or unstaged changes', 'AI-generated commit message', 'matches the repository's existing commit style' — giving several specific actions with minor coverage gaps (no mention of convention detection or diff analysis). It exceeds the 1-2-action anchor below but falls short of comprehensive coverage.

Completeness

Explicitly answers both: what ('Commit staged or unstaged changes with an AI-generated commit message that matches the repository's existing commit style') and when ('Use when the user asks to...') with concrete trigger phrases, matching the top anchor.

Trigger Term Quality

Five natural quoted phrases users would actually say — 'commit', 'commit changes', 'create a commit', 'save my work', 'check in code' — including non-obvious synonyms. Coverage is comprehensive for this domain; there are no natural variants missing (file extensions don't apply).

Distinctiveness Conflict Risk

Clear niche (git commit operation) with distinct trigger phrases; overlaps minimally with adjacent skills (e.g. commit-message drafting), mirroring the rubric's own good commit-related example.
