Conciseness

The body is lean and assumes competence — the Check/Fix/Code Review sections are one to three lines each with no concept explanations. Minor padding keeps it from a 5: the "mystery meat" motivational opener and the generic "Explain how clear labels... improve accessibility and general usability" line add little an expert needs.

Actionability

Some concrete guidance exists ("Add descriptive text content or `aria-label` attributes", "Flag exact elements, roles, labels, focus behavior, or keyboard interactions"), but the body itself contains no code, no tooling commands, and no specifics on how to audit — the executable HTML examples and axe/Lighthouse verification steps all live in references/rule.md. It is not a 4 because the in-body guidance stops at the level of direction rather than executable instruction; it is above a 2 because the fix and flagging targets are specific.

Workflow Clarity

The Check → Fix → Explain → Code Review section order forms a coherent, unambiguous sequence for a simple single-purpose audit skill, and verification is addressed ("note how to verify the fix with browser accessibility tooling or assistive tech", with a detailed Verification section in the reference). Not a 5 because there is no explicit validate-the-fix checkpoint or feedback loop stated as a step in the body itself.

Progressive Disclosure

The body is a well-organized overview (Quick Reference, Check, Fix, Explain, Code Review) that defers all implementation detail to references/rule.md — a real file, verified to exist, one level deep, and clearly signposted ("For full implementation details, code examples, and framework-specific guidance, see `references/rule.md`"). Navigation is easy and nothing that belongs in a separate file is inlined.

Specificity

The description lists several concrete actions — "Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output" — giving it real specificity. It falls short of a 5 because the embedded, ungrammatical rule title ("related to Provide accessible names for all interactive elements") muddles the core capability, and coverage drifts beyond naming into keyboard/focus territory without tying them together.

Completeness

Both components exist: the "what" is the check/inspect procedure and the "when" is an explicit "Use when reviewing rendered HTML, interactive components, or design-system patterns" clause, so it clears the level-3 cap. It is not a 5 because the "what" is expressed as a garbled embedded sentence rather than a clear capability statement, leaving the 'when' clause doing awkward double duty.

Trigger Term Quality

Natural trigger phrases like "reviewing rendered HTML, interactive components, or design-system patterns" and "screen-reader output" are present and phrased the way users would say them. A few obvious natural terms are missing — "accessibility", "a11y", "ARIA", "aria-label", "icon button" — which keeps it at 4 rather than 5.

Distinctiveness Conflict Risk

"Reviewing rendered HTML, interactive components, or design-system patterns" is broad enough that many other frontend/accessibility review skills (keyboard navigation, focus order, ARIA roles) would trigger on the same phrasing, and the description itself enumerates keyboard behavior and focus flow that belong to sibling rules. It is not a 2 because the accessible-names/screen-reader angle does anchor a recognizable niche.
