53%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 skill body is a clean, well-sectioned overview that correctly defers implementation detail to a real one-level-deep reference file, and it names the key techniques precisely. However, it contains no executable code inline, its fix workflow's verification steps are hidden in the reference, and its opening paragraph duplicates reference content instead of earning its tokens.
Suggestions
Delete the opening "More than half of users prefer dark mode..." paragraph (or reduce it to one line) — it is background Claude already knows and is duplicated verbatim in references/rule.md.
Inline a minimal copy-paste-ready snippet in the Fix section (the :root custom properties plus the prefers-color-scheme: dark override) so the body is actionable without opening the reference.
Make the review-then-fix sequence explicit (e.g., "1. Check for prefers-color-scheme/data-theme usage and hard-coded colors → 2. Fix via custom properties → 3. Verify rendered layout at affected breakpoints") and surface the reference's verification checklist in the body's workflow.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The opening paragraph ("More than half of users prefer dark mode for reduced eye strain... clean, maintainable addition rather than a disruptive refactor") is motivational background Claude already knows, and it is duplicated verbatim in references/rule.md's "Why It Matters" section. The rest (Quick Reference, Check, Fix, Explain, Code Review) is reasonably tight. Not score 2 because padding is confined to one paragraph; not score 4 because that paragraph plus the generic "Explain" section are tokens that could be trimmed or moved to the reference. | 3 / 5 |
Actionability | The body gives technique-level specifics ("@media (prefers-color-scheme: dark)", "CSS custom properties on :root", "localStorage and setting a data-theme attribute", "WCAG contrast ratios") but contains no code at all — every executable example lives in references/rule.md. This matches anchor 3 ("Some concrete guidance but incomplete... missing key details") better than 4 ("concrete code or commands with minor gaps"), since a reader of the body alone cannot execute the fix without opening the reference. | 3 / 5 |
Workflow Clarity | The Check → Fix → Explain → Code Review sections imply a review-then-fix sequence, but the order is implicit rather than stated, and validation checkpoints (the Verification steps exist only in references/rule.md) are not surfaced in the body. This fits anchor 3 ("Steps listed but validation gaps; sequence present but checkpoints missing or implicit"). Not score 2 because the sections do map to a coherent process; not score 4 because no explicit checkpoint or ordering statement is written. | 3 / 5 |
Progressive Disclosure | The body is a short overview with well-labeled sections and a clearly signaled one-level-deep pointer: "see `references/rule.md`" (which exists and holds the full code examples, toggle, and verification details). This matches anchor 4 ("Good structure; most content is appropriately placed... minor organization gaps") rather than 5 because the "why it matters" paragraph is duplicated verbatim between the body and the reference rather than cleanly split, leaving a minor placement gap. | 4 / 5 |
