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 actionable, well-sequenced, and uses clean one-level-deep progressive disclosure to offload full code examples to the reference file. Its only weakness is minor conceptual redundancy between the intro and Explain sections.
Suggestions
Trim the redundancy between the opening paragraph and the "Explain" section — keep the fallback mechanism explanation in one place to avoid restating a concept Claude already knows.
Consider folding the short "Explain" section's unique point (alt belongs on <img>, not <source>) into Quick Reference rather than re-explaining how <picture>/source ordering works.
The intro and Explain both cite IE11/unsupported-format fallback; consolidate into a single concise statement.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is mostly lean and well-organized, but the intro paragraph and the "Explain" section restate the same <picture>/<img> fallback mechanism — a concept Claude already knows — so some tokens could be trimmed; not quite the every-token-earns-its-place level. | 2 / 3 |
Actionability | The Check list names exact attributes (alt, width, height, type, srcset, media) and the Fix section gives a concrete markup template with specific attribute names and values, providing specific actionable guidance rather than vague direction. | 3 / 3 |
Workflow Clarity | A clear Check→Fix→Explain→Code Review sequence with the Check section itself acting as an explicit validation checklist and a verify step in Fix; this is a read-only review task so the destructive-feedback-loop cap does not apply. | 3 / 3 |
Progressive Disclosure | Well-organized sections plus a clearly signaled, one-level-deep pointer to references/rule.md (verified to exist) for full implementation details and code examples, splitting content appropriately. | 3 / 3 |
