The body is mostly efficient, but the 4.5:1 / 3:1 thresholds recur across Quick Reference, Check, and Explain, and the intro and Explain sections restate vision-deficiency statistics and the luminance formula that Claude already knows — tightened but not the lean, every-token-earns-its-place level expected at 3.

Guidance is concrete — exact ratios per text size, named tools (WebAIM, DevTools accessibility panel), all interactive states, and an opacity gotcha — but the body itself contains no executable snippet or worked color example (those live in rule.md), and the Fix is prose-level ('darken/lighten until it meets'), short of the copy-paste-ready anchor at 3.

Check → Fix → Explain → Code Review gives an implicit sequence and the Fix mentions verifying with a tool, but there is no explicit numbered workflow or validate → adjust → re-verify checkpoint, so checkpoints remain implicit rather than the explicit feedback loop expected at 3.

The body is a concise overview that clearly signals a single one-level-deep reference — 'For full implementation details, code examples, and framework-specific guidance, see references/rule.md' — and that file exists, giving clean navigation matching the well-signaled one-level-deep anchor.

The description enumerates concrete applicability targets ('visible text and text images, UI component borders (input fields, buttons), focus indicators, icons that convey meaning, and graphical objects'), but it states scope rather than concrete actions — there is no verb such as 'check' or 'fix' — so it falls short of the multi-action anchor at 3 while remaining more concrete than the vague anchor at 1.

The 'when' is explicit and even includes exclusions ('Use when applies to...', 'Does not apply to inactive/disabled UI components or purely decorative elements'), but the 'what does this do' is never stated as a capability, leaving one half of the what/when pair weak and capping completeness at 2 per the rubric guideline.

It lists relevant domain terms (input fields, buttons, focus indicators, icons) but omits the most natural user phrasings — 'color contrast', 'contrast', 'readable text' — and never actually uses the word 'contrast', yielding partial coverage rather than the natural-term spread expected at 3.

The contrast-applicability scope is fairly specific, but because the word 'contrast' is absent the description could overlap with other accessibility skills (alt text, ARIA, keyboard navigation), placing it between the distinct-niche anchor and the conflict-prone anchor.
