57%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured, brief overview with excellent progressive disclosure to references/rule.md. It is held back by generic, near-empty Check/Fix/Explain sections and the absence of any concrete markup example in the body itself.
Suggestions
Replace the generic Fix/Explain one-liners with concrete guidance — e.g., a minimal correct `<img srcset sizes>` snippet or the exact attributes to add — or fold them into the Code Review section to remove restatement.
Add one short example of correct responsive `<img>` markup (srcset + sizes + width/height) in the body so the core action is copy-paste ready without requiring the reference.
Tighten the Check section into a concrete verification step (e.g., "Confirm `sizes` matches the rendered layout width, not just the viewport") to give the workflow a real checkpoint.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is largely lean, but the Check/Fix/Explain one-liners ("Implement responsive images with srcset for different screen sizes and resolutions", "Explain how responsive images deliver optimized versions based on device capabilities") are generic restatements that restate the title rather than earning their tokens. | 2 / 3 |
Actionability | The Code Review section gives concrete flags ("Flag pages that always ship desktop-sized assets to mobile, omit `sizes`"), but the body provides no example srcset/sizes markup or commands, so the guidance is actionable yet incomplete. | 2 / 3 |
Workflow Clarity | A Check→Fix→Code Review structure is present, but it is loosely sequenced with no validation checkpoints, and the Fix/Explain sections are generic rather than concrete steps. | 2 / 3 |
Progressive Disclosure | The SKILL.md is a concise overview that clearly signals a single one-level-deep reference ("see `references/rule.md`") for full implementation details; the referenced file exists and content is appropriately split. | 3 / 3 |
