Conciseness

The body is mostly efficient domain-specific reference material (severity tables, CLI flags, rule arrays) that Claude would not already know, but the full inline rule reference (Type/Subject/Scope/Header/Body/Footer rule tables) plus dated external links ('accessed 2025-01-15') are tightening candidates that could be trimmed or split out, fitting the 'mostly efficient but includes some unnecessary explanation or could be tightened' anchor rather than the lean 4.

Actionability

It provides fully executable, copy-paste-ready guidance across the common cases: install commands for npm/yarn/pnpm, concrete CLI invocations ('npx commitlint --last'), complete JS/TS config examples, and working Python (extract_rules_for_prompt, validate_with_commitlint), matching the 'fully executable; copy-paste ready; covers common cases' anchor and clearly above the mostly-executable 4.

Workflow Clarity

The LLM Integration 'Validation loop pattern' is an explicit validate -> feed errors back -> retry -> return sequence with a feedback loop, satisfying the validation-checkpoint requirement for the risky validation path, but other sections (configuration setup, CLI usage) are listed without consistent checkpoints, fitting 'clear sequence with most checkpoints present; minor validation gaps' rather than the fully checkpointed 5.

Progressive Disclosure

The ~500-line body is well-structured with clear section headers, but it is monolithic: no bundle files exist (references/scripts/assets absent) and large reference content (the full rule tables, CLI reference, programmatic usage) that would naturally live in separate one-level-deep files is inlined, matching the 'some structure but could be better organized; content that should be separate is inline' anchor rather than the well-split 4.

Specificity

The description names the domain (commit message validation) and several concrete actions ('setting up commit message validation', 'configuring CI/CD to enforce commit format', 'extracting commit rules for LLM prompt generation', 'debugging commit message rejection errors'), but the actions are framed only as triggers rather than a comprehensive capability list, matching the anchor that names the domain with 1-2+ actions but is not comprehensive.

Completeness

The description is composed entirely of 'When ...' trigger clauses with no declarative 'what does this skill do' statement, which matches the anchor 'only when is present without what'. It is not a 3 because there is no clear standalone 'what' (the validating capability appears only in the body, not the description), and not a 1 because the when clauses are specific rather than extremely vague.

Trigger Term Quality

It includes natural, relevant trigger terms users would say ('commit message validation', 'CI/CD to enforce commit format', 'commit rules', 'LLM prompt generation') plus concrete file signals ('commitlint.config.js', '.commitlintrc'), giving good keyword coverage with only minor natural variations missing, fitting the 'good keyword coverage; a few natural terms missing' anchor rather than the fully comprehensive 5.

Distinctiveness Conflict Risk

It targets a clear niche (commitlint specifically) with distinct triggers like 'commitlint.config.js or .commitlintrc files' that are unlikely to fire for unrelated skills, leaving only minor overlap risk with a broader Conventional Commits skill, which fits the 'mostly distinct; minor overlap risk' anchor rather than the minimal-risk 5.
