The body is lean (~25 lines), assumes Claude knows git, and every line is actionable — it does not pad with explanations of what git or commits are, matching the 'lean and efficient; every token earns its place' anchor.

Provides concrete executable commands ('git status', 'git diff --cached', 'git log --oneline -5', 'git add <specific files>') plus a copy-paste-ready message format, fully actionable rather than abstract.

Clear numbered sequence with an explicit confirmation checkpoint before the destructive commit (step 6) and a secret-warning safety check (step 5); as a simple single-purpose skill this satisfies the validation-checkpoint requirement, so it is not capped at 2.

Under 50 lines with no need for external references and well-organized sections ('Git Commit Workflow', 'Commit Message Format'), which per the guidelines lets progressive disclosure score 3 on well-organized sections alone.

Names one concrete action ('Generate git commit messages from staged changes') and the domain, but does not list multiple specific actions like the score-3 anchor does; it is not vague, so above 1.

Clearly states what the skill does, but the 'when' is missing entirely — there is no explicit trigger clause, which per the guidelines caps completeness at 2.

Contains relevant natural terms ('git commit messages', 'staged changes') but lacks common variations and has no 'Use when...' trigger phrase, matching 'some relevant keywords but missing common variations' rather than full coverage.

The niche is fairly distinct (git commits), but without explicit triggers in the description it could overlap with general git skills, so it does not reach the clear-niche score-3 anchor.
