70%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
Well-organized with strong actionability and good progressive disclosure to a verified reference file. The main weaknesses are a somewhat redundant intro that explains familiar browser behavior and a missing validate-after-fix checkpoint in the body workflow.
Suggestions
Trim the intro paragraph to remove the explanation of how script tags block HTML parsing and FCP — Claude already knows this; keep the one-line Quick Reference as the summary.
Add an explicit validation step after 'Fix' (e.g., re-inspect the rendered markup or route to confirm scripts now carry defer/async) rather than leaving verification only in references/rule.md.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The intro paragraph re-explains how plain script tags block HTML parsing and how defer/async reduce FCP — browser behavior Claude already knows — and overlaps with the Quick Reference bullets. | 2 / 3 |
Actionability | Concrete directives ('Find all script tags… Flag any in the <head> without defer or async', 'Add defer or async… or convert to type=module') give clear executable guidance for an instruction-only skill. | 3 / 3 |
Workflow Clarity | Check, Fix, Explain, and Code Review sections form a sequence, but the Fix step lacks an explicit validation checkpoint to confirm the rendered markup now satisfies the rule. | 2 / 3 |
Progressive Disclosure | The body is a concise overview and detailed material (examples, decision guide, verification) is correctly split into the real references/rule.md, signaled clearly at one level of depth. | 3 / 3 |
