Conciseness

Mostly efficient (dense tables, no explaining of concepts Claude already knows), but the "Description" section restates the frontmatter, the "Features" table largely duplicates it, and the "Related Skills" table adds little actionable value — noticeably tightenable. Not 4 because the duplication between the Description and Features sections is more than 'minor instances'; not 2 because there is no padded conceptual explanation or fluff.

Actionability

Fully executable throughout: copy-paste scanner and contrast-checker commands with flags ("python scripts/a11y_scanner.py /path/to/project --json"), complete CLI option blocks for both scripts, slash-command variants, and a full before/after React example with exact WCAG citations and contrast ratios. Matches the level-5 anchor covering the common cases.

Workflow Clarity

The three-phase Scan → Fix → Verify workflow is clearly sequenced with a command per phase and a verification checkpoint (Phase 3 re-run with "--baseline audit-baseline.json" to confirm fixes and check regressions). Not 5 because there is no explicit error-recovery loop (e.g., 'if violations remain, re-fix and re-scan') and the Fix phase delegates to a reference; not 3 because validation is present, so the batch-operation cap for missing verification does not apply.

Progressive Disclosure

Good structure scored against the actual bundle: all nine references/ files exist, are linked one level deep with a descriptive navigation table plus two inline point-of-use links, and both scripts are documented. Not 5 because assets/sample-component.tsx is never referenced from SKILL.md (orphaned asset), and the Common Pitfalls table is content that could live in a reference file to keep the overview lean.

Specificity

Names several concrete third-person actions — "Scans with a11y_scanner.py", "checks contrast with contrast_checker.py", "then fixes and re-verifies" — with the tool scripts explicitly named. Not 5 because capabilities demonstrated in the body (compliance report generation, CI integration, framework-specific fix code) are absent from the description; not 3 since it goes well beyond 1-2 generic actions.

Completeness

Explicitly answers both: what ("Scans with a11y_scanner.py and checks contrast with contrast_checker.py, then fixes and re-verifies") and when ("Use for any accessibility audit or a11y fix" with concrete parenthetical trigger phrases). Matches the level-5 anchor with concrete trigger phrases; level 4's 'when could be more explicit' does not apply here.

Trigger Term Quality

Good natural-term coverage including the "a11y" synonym, "WCAG 2.2 A/AA", "color contrast", "compliance report", "CI check", and all five framework names plus HTML. Not 5 because common user phrasings like "screen reader", "ARIA", "keyboard navigation", "tab order", or standards like "Section 508/ADA" are missing; not 3 since coverage with synonyms is clearly better than 'some relevant keywords'.

Distinctiveness Conflict Risk

Accessibility auditing with WCAG triggers and named scanner scripts is a clear niche with minimal conflict risk. Not 5 because general code-review or frontend skills could plausibly claim overlapping triggers (e.g., "fix this component"); not 3 since the a11y/WCAG trigger set is far more distinct than 'somewhat specific'.
