The body is short and does not over-explain concepts Claude knows, but the Quick Reference bullets ("Place all <dt>... within a <dl>", "Avoid using description list items as standalone elements") overlap with the Check and Fix sections and could be tightened.

For an instruction-only review skill the guidance is concrete and actionable — "Locate any <dt> or <dd> elements that are not children of a <dl>" and "Wrap orphaned <dt> and <dd> elements in a parent <dl> container" — which the rubric rewards without requiring inline code.

The Check → Fix → Explain → Code Review sequence is clear and unambiguous for a simple single-task review skill, and verification is referenced in the Code Review section; no destructive/batch operation requires an inline validation checkpoint.

The body is a concise overview that signals a single one-level-deep reference ("see references/rule.md") for full implementation details, code examples, and framework guidance; the referenced file exists and is self-contained with no nested indirection.

The description lists multiple concrete actions — "Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output" — rather than vague language, matching the anchor for listing several specific concrete actions.

It has an explicit "Use when..." trigger clause and states what the skill does (the check/inspect actions), clearly answering both what and when; not capped at 2 because the trigger guidance is explicit.

It includes natural terms a reviewer would actually say ("rendered HTML", "interactive components", "design-system patterns", "definition items in a definition list"), giving good coverage rather than just technical jargon.

The rule-specific phrase ("Wrap definition items in a definition list") is distinct, but the leading "reviewing rendered HTML, interactive components, or design-system patterns" reads as a shared template across sibling accessibility skills and could overlap with them.
