The body is lean and assumes Claude's competence; the translation table and phrasing rules are actionable rephrasing standards rather than explanations of concepts Claude already knows, and there is no padding.

Provides a concrete output template (What changed / Why it matters / How I verified it / What is still not proven), explicit phrasing rules ('measured faster' only when before/after measurements exist), and specific term-to-plain-language mappings — concrete, executable guidance for an instruction-only skill.

The three-job workflow (Audit -> Verify -> Explain) is clearly sequenced with an ordered evidence-preference list and explicit handling of partial and failed verification; this is not a destructive/batch operation, so no feedback-loop cap applies.

A single self-contained file with no nested references and well-organized sections (Core Rule, Workflow, Explanation Standards, Output Rules), appropriate for a skill that needs no external bundle files.

Lists multiple concrete actions — 'Audit work, verify claims with concrete evidence, and explain the result in simple grade-5 language' — rather than vague domain language, matching the anchor for naming several specific actions.

Explicitly answers both what (audit, verify, explain in grade-5 language) and when via the 'Use when the user asks to...' clause, so it is not merely implied.

Covers natural terms users would say — 'review, audit, check, verify, explain a change, explain a fix, summarize test results, validate whether something works, translate technical findings into plain language' — giving broad coverage of common phrasings.

The grade-5 plain-language translation niche is distinctive, but the core triggers (review, check, verify, explain, summarize) are generic verbs that overlap with general review and summarization skills, so it could still trigger for a similar skill.
