The body is lean — short bullets and one-line section descriptions that do not re-explain concepts Claude already knows — so it earns the 'lean and efficient' anchor despite minor HTML-entity escaping clutter.

As an instruction-only review skill it gives concrete directives ('Ensure dl contains only dt, dd...', 'Flag exact elements, roles, labels, focus behavior') and defers executable examples to the real references/rule.md, satisfying the actionable-guidance bar without requiring inline code.

The Quick Reference → Check → Fix → Explain → Code Review sections form a clear review sequence and the single review action is unambiguous, meeting the simple-skill bar; verification is signaled though deferred to the reference rather than an explicit in-body checkpoint.

The body is a concise overview with a clearly signaled one-level-deep reference ('see references/rule.md') plus the rule-page URL, and the referenced file exists and is well organized, matching the clear-overview anchor.

Lists multiple concrete review actions — 'inspect keyboard behavior, focus flow, accessible names, and screen-reader output' — matching the multi-action anchor rather than the single-domain level below.

Both halves are explicit: 'Use when reviewing rendered HTML...' answers when, and the inspection actions answer what, matching the clear what-and-when anchor.

Some natural terms appear ('rendered HTML', 'interactive components'), but the core definition-list vocabulary ('definition list', 'dl/dt/dd', 'accessibility') is largely missing and 'Use correct definition list structure' is an awkwardly interpolated rule title, so it is not at the full-coverage level.

The broad trigger ('rendered HTML, interactive components, or design-system patterns') overlaps with general HTML/accessibility-review skills, and the actual definition-list niche is buried rather than clearly differentiated.
