accessibility-audit

Run a comprehensive WCAG accessibility audit covering perceivable, operable, understandable, and robust principles. Use this skill whenever the user wants to audit accessibility, review WCAG compliance, fix accessibility issues, prepare for accessibility certification, address an accessibility lawsuit risk, or systematically improve a site's accessibility. Triggers on accessibility audit, WCAG audit, a11y audit, accessibility compliance, ADA compliance, screen reader test, keyboard navigation, accessibility report, fix accessibility, axe scan. Also triggers when accessibility issues have been reported and need systematic remediation.

Quality

Content

67%Weight 40%Scale 1-5

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

A well-organized, actionable audit methodology with concrete tools, keyboard tests, and thresholds, supported by three real one-level reference files. The main weakness is mild verbosity from restating WCAG criteria inline that duplicates the quick-reference file.

Suggestions

Trim the four-principles section: replace the principle definition lines Claude already knows with direct audit checks, and defer full criteria to references/wcag-quick-reference.md.

Add one or two runnable commands for the named CLI tools (e.g., a sample `pa11y` invocation) to lift actionability from mostly-executable to copy-paste-ready.

Add an explicit validation checkpoint in the workflow (e.g., re-scan after remediation to confirm each P0/P1 finding is resolved) to close the validate-fix-retry loop.

DimensionReasoningScore

Conciseness

Mostly efficient and well-structured, but the four-principles section restates WCAG criteria definitions Claude already knows (e.g., 'Information and UI must be presentable in ways users can perceive') and duplicates detail likely present in references/wcag-quick-reference.md, so it could be tightened; fits the 'mostly efficient but includes some unnecessary explanation' anchor rather than 4.

3 / 5

Actionability

Concrete and specific—names tools (axe DevTools, Lighthouse, WAVE, Pa11y), exact keyboard keys (Tab, Shift+Tab, Enter, Space, arrows, Escape), screen reader combos, and measurable thresholds (4.5:1, 200% zoom, 320px)—but tool names appear without runnable commands, a minor gap keeping it at 'mostly executable guidance' rather than copy-paste-ready 5.

4 / 5

Workflow Clarity

A clear 10-step sequenced workflow with a built-in feedback checkpoint via the data-availability rule ('state the gap') and the 'If required data is unavailable' section, but it lacks an explicit validate-then-fix-retry loop; fits 'clear sequence with most checkpoints present; minor validation gaps' rather than 5.

4 / 5

Progressive Disclosure

Good structure with a dedicated Reference files section pointing to three real one-level-deep files (audit-report-template.md, wcag-quick-reference.md, aria-patterns.md), but inline WCAG criteria detail overlaps the quick-reference file, a minor organization gap keeping it just below the 'appropriately split' 5 anchor.

Description

91%Weight 40%Scale 1-5

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

A strong, third-person description with explicit what/when structure and rich, natural trigger terms including synonyms and a tool name. Minor overlap risk with adjacent QA/design skills keeps distinctiveness just below the top anchor.

DimensionReasoningScore

Specificity

Names the domain (WCAG accessibility audit) and several concrete actions—'audit accessibility,' 'fix accessibility issues,' 'prepare for accessibility certification,' 'address an accessibility lawsuit risk'—with only minor coverage gaps, fitting the 'lists several specific actions' anchor rather than the 5 which would require a fully comprehensive action set.

4 / 5

Completeness

Explicitly answers both what ('Run a comprehensive WCAG accessibility audit covering perceivable, operable, understandable, and robust principles') and when ('Use this skill whenever the user wants to...' plus explicit 'Triggers on' phrases), matching the anchor requiring clear what-and-when with concrete trigger phrases.

5 / 5

Trigger Term Quality

Comprehensive natural-term coverage including synonyms and a tool name: 'accessibility audit, WCAG audit, a11y audit, accessibility compliance, ADA compliance, screen reader test, keyboard navigation, accessibility report, fix accessibility, axe scan'—matching the 'comprehensive coverage including synonyms' anchor; not below because no common variant is missing.

5 / 5

Distinctiveness Conflict Risk

Clear accessibility niche with distinct triggers and minimal conflict risk, but terms like 'accessibility compliance' and 'fix accessibility' have minor overlap with general QA or design-standards skills, so it sits at 'mostly distinct; minor overlap risk' rather than the 5 anchor.
