77%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.
The body is a well-structured overview with an unambiguous check-fix-explain workflow, an embedded validation checkpoint, and exemplary progressive disclosure through a single well-signaled reference that contains the full implementation detail. Its only real weakness is redundancy: the vestibular rationale is repeated three times and the Code Review section restates generic review boilerplate.
Suggestions
State the vestibular depth-mismatch rationale once (in the intro or Explain section) and drop the duplicates in Quick Reference and the other section, cutting roughly three lines of repeated content.
Trim or concretize the generic "Code Review" boilerplate ("Flag exact elements, roles, labels, focus behavior, or keyboard interactions") to focus on what parallax review actually flags — missing prefers-reduced-motion guards, content hidden in parallax-only layers, and absent motion toggles.
Optionally surface the manual verification steps from references/rule.md (enable OS "Reduce motion", confirm effects disable and content remains readable) as two or three explicit checklist lines in the Check section so validation does not depend on opening the reference.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The vestibular depth-mismatch fact is stated three times nearly verbatim (intro "mismatch between what the eyes see and what the inner ear senses—triggering dizziness, nausea, and vertigo", Quick Reference "Parallax creates depth mismatch triggering vestibular disorders", and Explain "create a depth mismatch that can trigger vestibular disorders"), and the Code Review section repeats generic review boilerplate. Mostly efficient, but the duplication could be tightened — the middle anchor. | 3 / 5 |
Actionability | "Wrap parallax effects in @media (prefers-reduced-motion: no-preference) queries. Provide static fallbacks that convey the same content. Consider adding a user toggle to disable motion effects site-wide" is concrete, specific guidance naming the exact media feature, with full executable CSS/JS/React examples one hop away in references/rule.md. Not 5 because the body itself contains no inline executable example; above 3 because the instruction is specific and actionable rather than pseudocode-level. | 4 / 5 |
Workflow Clarity | This is a simple, single-purpose skill whose action is unambiguous: Check gives detection criteria ("background and foreground move at different speeds") with an explicit validation checkpoint ("Verify these effects are disabled when prefers-reduced-motion is set, and essential content is accessible without the effect"), followed by Fix and Explain. Per the simple-skill guideline, the single clear action with an embedded verification step earns the top score. | 5 / 5 |
Progressive Disclosure | The body is a lean overview under 50 lines with a single, clearly signaled one-level-deep reference — "For full implementation details, code examples, and framework-specific guidance, see references/rule.md" — and that file exists and delivers exactly the promised CSS, JavaScript, React, and verification content. Content is appropriately split and easy to navigate. | 5 / 5 |
