57%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The skill is well-structured with good progressive disclosure to a real reference file, but it carries conceptual redundancy and defers both its complete code examples and its verification steps to the reference rather than surfacing a validation checkpoint inline.
Suggestions
Trim or remove the 'Explain' section's browser-behavior primer and the duplicated intro paragraph; keep only what is not common knowledge.
Add an explicit inline verification step to the Check/Fix workflow (e.g. 'Verify in DevTools Network tab that no image requests return 4xx and the fallback renders').
Move the 'Code Review' section's framing into the Check/Fix steps or into the reference to reduce overlap between Check and Code Review.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is mostly efficient, but the 'Explain' section re-describes browser 404/broken-icon behavior Claude already knows and the intro paragraph duplicates the reference's 'Why It Matters' content. | 2 / 3 |
Actionability | A concrete copy-paste onerror handler ('onerror="this.src='/images/fallback.png'; this.onerror=null;"') and numbered fix steps are present, but the full executable examples (build-time validation script, React component, monitoring) live only in references, leaving the body's guidance incomplete on its own. | 2 / 3 |
Workflow Clarity | Check → Fix → Explain → Code Review is sequenced, but the body lacks an explicit validation/verification checkpoint (e.g. confirm in DevTools Network tab), which the rubric caps at 2 for batch image operations. | 2 / 3 |
Progressive Disclosure | The body is a concise overview with a clearly signaled, one-level-deep pointer to the real 'references/rule.md' for full implementation details, matching the well-organized one-level reference anchor. | 3 / 3 |
