Conciseness

The body is lean and assumes Claude's competence, with no padding explaining basic concepts; every section (Core Rule, Workflow, Explanation Standards, Output Rules) earns its place.

Actionability

Provides concrete executable guidance for an instruction-only skill — an ordered evidence-preference list, a copy-paste markdown output template, and specific phrasing rules — but lacks a worked end-to-end example covering common cases.

Workflow Clarity

A clear three-step Audit -> Verify -> Explain sequence with explicit partial-failure and overclaiming checkpoints; falls short of 5 because the checkpoints stay somewhat high-level rather than forming a formal validate-fix-retry loop.

Progressive Disclosure

A well-organized single-purpose skill under 50 lines of guidance with clean section headers and no need for external references, meeting the simple-skill exception for a top score.

Specificity

Names three concrete actions ('Audit work', 'verify claims with concrete evidence', 'explain the result in simple grade-5 language'), going beyond the 1-2 of a score 3, but not a comprehensive multi-action enumeration of a score 5.

Completeness

Explicitly answers both what ('Audit work, verify claims with concrete evidence, and explain the result in simple grade-5 language') and when ('Use when the user asks to review, audit, check, verify...') with concrete trigger phrases.

Trigger Term Quality

Comprehensive natural-term coverage with abundant user phrasings and synonyms ('review, audit, check, verify, explain a change, explain a fix, summarize test results, validate whether something works, translate technical findings into plain language').

Distinctiveness Conflict Risk

The three-job audit/verify/grade-5-explain framing is a fairly distinct niche with clear triggers, but the individual review/explain verbs carry minor overlap risk with other general-purpose review skills.
