Quality

Content

72%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is token-efficient and well-structured with proper progressive disclosure, but the core guidance is abstract and lacks executable examples or validation checkpoints within the body itself.

Suggestions

Add a small executable example in the body (e.g., a before/after markup snippet showing an invalid vs. valid aria-expanded value) so guidance is copy-paste ready without opening the reference.

Include an explicit validation step in the review workflow, such as how to confirm the fix with browser accessibility tooling or a screen reader, to close the workflow-clarity gap.

Tighten the generic Check/Fix/Explain one-liners into specific, concrete instructions rather than restating the rule.

DimensionReasoningScore

Conciseness

The body is lean — short bullet points and one-line sections with no padding or explanation of concepts Claude already knows, so every token earns its place.

3 / 3

Actionability

The Quick Reference gives some concrete examples ("aria-expanded='true'", avoid yes/no, check IDs in aria-labelledby/aria-owns) but the Check/Fix sections are abstract ("Validate that all ARIA attribute values conform to the allowed types") with no executable code, deferring examples to the reference file.

2 / 3

Workflow Clarity

Sections (Check, Fix, Explain, Code Review) imply a sequence but it is only implicit, with no explicit validation checkpoints or feedback loop for confirming a fix.

2 / 3

Progressive Disclosure

The body is a concise overview that clearly signals a single one-level-deep reference ("see `references/rule.md`") which exists, with well-organized sections and easy navigation.

Description

85%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific, complete with an explicit trigger, and occupies a clear niche, but the trigger phrasing is marred by an awkwardly embedded rule title instead of natural user keywords.

Suggestions

Reword "related to Use valid values for ARIA attributes" into natural trigger phrasing such as "Use when reviewing ARIA attributes for valid values" to improve trigger term quality.

Add common natural variations users might say (e.g., "ARIA roles", "screen reader compatibility", "accessibility audit") to broaden trigger coverage.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "reviewing rendered HTML, interactive components, or design-system patterns", "Check native semantics first", "inspect keyboard behavior, focus flow, accessible names, and screen-reader output" — matching the anchor for several specific concrete actions.

3 / 3

Completeness

It opens with an explicit "Use when..." trigger and names both what the skill does and when to apply it, satisfying the anchor for clearly answering both what and when.

3 / 3

Trigger Term Quality

Relevant keywords appear (HTML, interactive components, ARIA attributes, keyboard behavior) but the awkward embedded rule title "related to Use valid values for ARIA attributes" is not natural user phrasing and common variations are missing.

2 / 3

Distinctiveness Conflict Risk

It targets a narrow accessibility niche (valid ARIA attribute values) with distinct triggers, making confusion with unrelated skills unlikely.
