Conciseness

The body is lean and assumes Claude's competence — it never explains what READMEs, docstrings, or symbols are. The brief published-research stat directly motivates the guard's premise rather than padding, and each rule earns its place, matching the 'lean and efficient; every token earns its place' anchor rather than including unnecessary explanation (2).

Actionability

As an instruction-only skill its guidance is concrete and executable ('verify... by reading it, not recalling it', 'Grep the docs for the old symbol before finishing', 'Read the implementation before describing it') with a copy-paste reporting template and a mechanical verification procedure referenced, matching the actionable anchor; per scoring notes absence of code is not penalized.

Workflow Clarity

The workflow is clearly sequenced (adapt to project -> apply rules grouped by severity -> self-check -> report) with an explicit validation gate ('If any answer is wrong, fix it before showing the user'), matching the 'clear sequence with explicit validation steps' anchor rather than listing steps with implicit checkpoints (2).

Progressive Disclosure

SKILL.md is a clear overview with well-signaled, one-level-deep references to five real bundle files (all verified present: verification, code-samples, docstrings, review-checklist, sources), content is appropriately split out of the main body, and a dedicated References section describes each file's purpose, matching the 'clear overview with well-signaled one-level-deep references' anchor.

Specificity

Lists multiple concrete actions ('verify every referenced function, flag, endpoint, config key, and code sample against the source', 'catch docs-vs-code drift', 'strip filler and unverifiable claims') and enumerates specific doc surfaces, matching the 'lists multiple specific concrete actions' anchor rather than naming only some actions (2).

Completeness

Explicitly answers both what (review/verify docs, catch drift, strip filler) and when, with an explicit 'Use when the user says...' trigger clause plus reactive timing guidance, matching the anchor that clearly answers both with explicit triggers rather than leaving when only implied (2).

Trigger Term Quality

Provides strong natural-language coverage users would actually say ('review the docs', 'is this documentation accurate', 'write a README', 'document this API', 'add a docstring', 'add a changelog entry'), matching the 'good coverage of natural terms' anchor rather than missing common variations (2).

Distinctiveness Conflict Risk

Carves a clear niche (documentation vs code) and explicitly disambiguates via 'DO NOT USE for production code review (use clean-code-guard), test review (use test-guard)...', matching the 'clear niche with distinct triggers; unlikely to conflict' anchor rather than overlapping with similar skills (2).
