Conciseness

The body is efficient — it states the 7 rules as terse imperatives without explaining git basics, and the principles add genuinely new guidance ('never reference review feedback', 'avoid bullet points'). It falls short of 5 because the 'Checklist Before Committing' section restates rules 2-7 almost verbatim, a minor duplication that could be trimmed.

Actionability

Fully executable guidance: a copy-paste-ready heredoc git commit command, paired good/bad example messages with the failure mode named ('Problem: Vague subject', 'Problem: Over-explains implementation details'), and a concrete pre-flight checklist. This matches the anchor 'fully executable; copy-paste ready code or commands; specific examples cover the common cases'.

Workflow Clarity

For this single-task skill the action is unambiguous — apply the rules, use the given heredoc format, then run the explicit 'Checklist Before Committing' as a validation checkpoint before executing. The checklist provides the verification step, so it sits above anchor 4; there is no multi-step sequence to gap, and commits are not a destructive/batch operation that would demand a stronger feedback loop.

Progressive Disclosure

A single self-contained file with no references/scripts/assets bundle; all content (rules, format, examples, checklist) appropriately lives inline at this size, and the section headers make navigation trivial. This matches the simple-skill pattern of well-organized sections earning the top anchor; nothing is inlined that belongs in a separate file.

Specificity

The description names the domain ('commit messages') and references concrete anchors ('Applies the 7 rules for great commit messages with focus on conciseness and imperative mood'), but does not enumerate the actual capabilities (subject-line limits, body wrapping, heredoc format), matching the anchor 'names domain and 1-2 concrete actions, but not comprehensive'. It is not a 4 because no several specific actions are listed, and not a 2 because the actions named are concrete rather than generic.

Completeness

Both halves are explicit: 'Use when creating git commits' (when) and 'Applies the 7 rules for great commit messages with focus on conciseness and imperative mood' (what). It does not reach 5 because the 'what' stays at the level of named rules rather than concrete trigger-phrase-level detail of what the skill does, matching the anchor 'both what and when; when could be more explicit or specific' — here it is the 'what' that could be more specific.

Trigger Term Quality

'Use when creating git commits' and 'commit messages' are exactly the natural phrases a user would say, giving good keyword coverage. It is short of 5 because common variations like 'committing changes', 'write a commit message', or 'git commit' phrasing are not covered, and above 3 because the core natural terms are present rather than merely relevant.

Distinctiveness Conflict Risk

'Git commits' and 'commit messages' form a clear niche with distinct triggers and minimal overlap with other skills (e.g., code review or PR skills). No generic phrasing that would fire for the wrong skill, matching the anchor 'clear niche with distinct triggers; minimal conflict risk'.
