The body is mostly lean and well-sectioned, but the Explain section restates figure/figcaption semantics Claude already knows and overlaps the intro paragraph, so it could be tightened.

The Check and Fix sections give concrete numbered steps, but the body only instructs "Show the corrected HTML" without an inline executable example, deferring all code to the reference.

A clear Check→Fix→Explain sequence is present with an explicit four-point verification checklist and a "confirm the fix in DevTools" checkpoint, appropriate for this review skill.

The body is a concise, well-organized overview that signals a single one-level-deep reference (references/rule.md, which exists), splitting detail appropriately.

Lists several concrete actions ("Check encoded size, rendered size, loading strategy, and above-the-fold impact together"), but the description uses imperative second-person voice ("Check…") rather than third-person declarative, so specificity is reduced by 1 per the voice guideline.

It explicitly states both what it does ("Check encoded size, rendered size, loading strategy, and above-the-fold impact") and when to use it ("Use when reviewing image assets, markup, and CDN or build transforms…"), matching the explicit-trigger anchor.

Relevant terms are present ("image captions", "figure", "figcaption", "image assets", "CDN"), but the rule title is embedded verbatim mid-sentence and "CDN or build transforms" is jargon that users would not naturally say, leaving common variations missing.

The figure/figcaption caption niche is distinct, but the broad framing ("CDN or build transforms", "loading strategy", "above-the-fold impact") pulls in general image-performance territory that could overlap with other image-optimization skills.
