66%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 concise, well-structured into a Check/Fix/Explain/Code Review workflow, and appropriately offloads detail to a real references/rule.md file. Its main gap is actionability: concrete async/defer/lazy-load code examples live only in the reference, leaving the body mostly instructional.
Suggestions
Add one short inline code example showing async vs defer vs lazy-load script tags so the body is actionable without opening the reference.
Add an explicit validation checkpoint after 'Fix' (e.g., re-measure in Lighthouse/DevTools to confirm the blocking time dropped).
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is short, well-sectioned, and assumes Claude's competence; the only mild padding is the marketing-style opener ('#1 cause of slow websites—2-5 seconds') which is not strictly necessary. | 4 / 5 |
Actionability | Guidance is mostly directional ('Use async', 'Use defer', 'Lazy-load') with no inline executable code or concrete attribute examples; the actual code is deferred to references/rule.md rather than shown in the body. | 3 / 5 |
Workflow Clarity | The Check -> Fix -> Explain -> Code Review sequence gives a clear, ordered flow, and Code Review explicitly asks to describe the measurement method used to confirm the issue; minor gap is there is no explicit validate/re-check checkpoint after applying fixes. | 4 / 5 |
Progressive Disclosure | The body is a clean overview that signals a single one-level-deep reference (references/rule.md), which exists as a real file; navigation is clear, though the reference is text rather than a linked path. | 4 / 5 |
