84%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A clean, token-efficient overview with a sensible audit-fix-review workflow and good progressive disclosure via one real reference file. The main gap is actionability: the body describes what to do but defers all executable code to the reference.
Suggestions
Include at least one small executable snippet (e.g., the web-vitals onINP call or a scheduler.yield example) directly in the body so Claude can act without opening the reference.
Add a brief validation/checkpoint note in the Fix section tying the 200ms threshold back to the measurement step.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and well-organized with tight Quick Reference, Check, Fix, and Explain sections; it assumes Claude's competence and pushes detail to the reference file rather than padding. | 3 / 3 |
Actionability | Guidance is concrete in direction ('break up long tasks', 'use web workers') but the body itself contains no executable code or commands — those live only in references/rule.md, so it stops at descriptive instruction. | 2 / 3 |
Workflow Clarity | The Check → Fix → Explain → Code Review sequence is clear and unambiguous for this single-task skill, and it explicitly instructs verifying the bottleneck in DevTools/Lighthouse/field data before recommending changes. | 3 / 3 |
Progressive Disclosure | The SKILL.md is a concise overview with a single, clearly signaled one-level reference to references/rule.md (which exists), keeping navigation shallow and easy. | 3 / 3 |
