85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is well-structured, highly actionable, and properly splits detail into a one-level-deep reference. Its main weakness is conciseness: it re-explains well-known SEO/accessibility concepts and repeats the Google update across sections.
Suggestions
Collapse the redundant Google 2017 update mentions (Quick Reference, Check, Explain) into a single statement to remove repetition of a concept Claude already knows.
Trim the Explain section to only what is non-obvious — keep the WCAG SC numbers (2.1.2, 4.1.3) but drop the general re-explanation of why modal focus management matters.
Merge the intro paragraph into Quick Reference since both cover mobile/accessibility/SEO impact, eliminating overlapping prose.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient but re-explains concepts Claude already knows (the 2017 Intrusive Interstitials Update, WCAG/ARIA dialog pattern) and repeats the Google update across Quick Reference, Check, and Explain, so it could be tightened. | 2 / 3 |
Actionability | Provides concrete actionable guidance — specific selectors (position: fixed/absolute with high z-index), a concrete breakpoint (< 600px width), numeric fix constraints (max-height 10-15% of viewport), and exact ARIA attributes (role='dialog', aria-modal='true', aria-labelledby, Escape, focus return). | 3 / 3 |
Workflow Clarity | The Check section is a numbered 5-point checklist culminating in the explicit validation step "Flag dialogs that fail any of these checks," and Fix is sequenced 1–4 with sub-steps, giving a clear review workflow. | 3 / 3 |
Progressive Disclosure | SKILL.md is a well-sectioned overview that defers full implementation, code examples, and framework guidance to a single, clearly signaled one-level-deep reference at references/rule.md (verified to exist). | 3 / 3 |
