86%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
An excellent, dense standards body: every section is a concrete, actionable rule with exact thresholds, attributes, and tooling, and a genuine validate-and-re-run loop. The main weakness is the dangling REFERENCE.md pointer — the deferred composite-widget patterns are neither inlined nor available in the bundle, leaving the skill's most complex topic (roving tabindex, aria-activedescendant) unaddressed.
Suggestions
Create references/REFERENCE.md with the composite widget patterns (roving tabindex, aria-activedescendant) and link it properly (e.g., "in [REFERENCE.md](references/REFERENCE.md)"), or inline the two patterns as short bullet rules and drop the pointer — currently the referenced file does not exist in the bundle.
Add one line ordering the workflow (e.g., apply section rules while building, then run the Validation section before finishing) so the rule sections and the validation loop have an explicit sequence.
Clarify the navigation pattern section: it says "roving tabindex across top-level items" but defers the actual implementation to the missing REFERENCE.md — either include a minimal code snippet or move both mentions to the same location.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is a lean rule set: exact ratios ("≥4.5:1", "≥3:1"), exact attributes, one precise CSS snippet, and tool names — with zero explanation of concepts Claude already knows. Every token earns its place, matching the "lean and efficient" anchor. | 5 / 5 |
Actionability | Guidance is fully concrete and executable throughout: exact contrast ratios and pixel thresholds, exact ARIA attributes ("aria-invalid=\"true\" + aria-describedby"), a copy-paste-ready skip-link CSS rule, a page-title format template, and named validation commands ("axe-core (axe-playwright or pa11y in CI)"). This is instruction-only guidance at copy-paste specificity, matching the 5 anchor for non-code skills. | 5 / 5 |
Workflow Clarity | The Validation section provides a real feedback loop ("fix all high/critical findings and re-run until clean", plus manual tab-through), which is strong. It falls between anchors 4 and 5 rather than clearly at 5 because the body is a set of parallel rule sections with no guidance on sequencing the checks within a development workflow (e.g., when the tab-order or contrast checks apply relative to building a component). | 4 / 5 |
Progressive Disclosure | Sections are well-organized and the body is appropriately short, but the one external pointer — "Composite widget patterns (roving tabindex, `aria-activedescendant`) in REFERENCE.md" — is not clearly signaled (no path or link) and no such file exists in the bundle (no references/ directory is present). This matches the anchor for references present but not clearly realized, rather than the good-structure anchor 4. | 3 / 5 |
