71%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.
A well-structured, actionable body with excellent progressive disclosure (one-level-deep references verified to exist) and a clear four-step workflow. Its main weakness is token efficiency: block quotes of RFC 6749's grant taxonomy and RFC 7636's PKCE methods re-explain concepts Claude already knows.
Suggestions
Replace the RFC 6749 four-grant block quote in the Overview with a single line ('Four grants defined in RFC 6749; RFC 9700 deprecates Implicit and RO-Password — Auth Code + PKCE is canonical'), keeping only the operative deprecation guidance.
Replace the RFC 7636 §4.2 method quote with the existing one-line rule ('Always use S256; plain defeats the purpose of PKCE') plus the code, which already implements S256.
Tighten the worked example's intro: the five-step flow walk-through can reference RFC 6749 §4.1 directly rather than restating it.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body block-quotes RFC 6749's four-grant taxonomy and RFC 7636's §4.2 plain/S256 method list — OAuth grant taxonomy and PKCE mechanics Claude already knows; 'Always use S256' and the RFC 9700 deprecation lines carry the operative points alone. Mostly efficient elsewhere (tables, worked example, checklist), but the RFC quotes are removable padding. | 3 / 5 |
Actionability | The worked example is near copy-paste-ready Python/Playwright with a working PKCE pair generator, concrete asserts, and a decision table mapping client type to required tests. Minor gaps keep it from 5: IdP login selectors and Playwright fixtures are assumed rather than specified. | 4 / 5 |
Workflow Clarity | 'How to use' gives a clear four-step authored sequence culminating in an explicit end-to-end coverage checklist, and the anti-patterns table maps each failure to a fix. No explicit 'run the tests and confirm outcomes' feedback loop, but test authoring is neither destructive nor batch, so the workflow_clarity cap does not apply; the checklist serves as the validation checkpoint, placing this above 3. | 4 / 5 |
Progressive Disclosure | SKILL.md is a true overview: the canonical flow is worked inline, while all negative-case and secondary-grant detail is split one level deep into references/per-flow-test-recipes.md, repeatedly and specifically signposted ('the negative state-mismatch test, plus the client-credentials, refresh-rotation, OIDC-nonce, scope-downgrade, and redirect-URI recipes, are in references/per-flow-test-recipes.md'), and the referenced file exists with exactly that content. No nesting beyond one level. | 5 / 5 |
