40%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 body succeeds as a lean navigation tier with a clean, verified one-level pointer to a substantial reference file, but it spends much of its token budget re-explaining basic auth concepts, offers no executable guidance beyond a few rule-of-thumb parameters, and provides no sequenced implementation workflow or validation checkpoints. It reads more as a concept summary than an implementation guide despite the skill's stated purpose.
Suggestions
Replace the 'Core Concepts' section with a brief strategy-selection guide (e.g., 'session-based for traditional server-rendered apps; JWT for stateless/horizontally scaling APIs; OAuth2/OIDC for delegated or social login') so the top tier adds decision value instead of re-explaining AuthN/AuthZ basics.
Add a short sequenced implementation workflow (choose strategy → apply the matching pattern from references/details.md → verify against the security checklist) with explicit validation checkpoints such as testing token expiry, refresh flow, and CSRF protection.
Include one small executable snippet inline (e.g., a bcrypt/argon2 hashing call or an httpOnly cookie options object) so the top-level tier is immediately actionable without opening the reference.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Roughly a third of the body re-explains textbook concepts Claude already knows — "Authentication (AuthN): Who are you? Verifying identity (username/password, OAuth, biometrics)", "Server stores session state, Session ID in cookie", "Use HTTPS: Encrypt data in transit" — fitting 'noticeably verbose; several unnecessary explanations or padded sections'. Not 1 because the material is compact bullets rather than heavily padded prose, and the When to Use list and pitfalls carry real value. | 2 / 5 |
Actionability | Some concrete directives exist ("Always hash with bcrypt/argon2", "15-30 minutes max", "httpOnly, secure, sameSite flags"), but the body contains no executable code, commands, or implementation steps — all executable content is deferred to references/details.md — fitting 'some concrete guidance but incomplete'. Not 4 because the inline specifics are rule-of-thumb parameters rather than executable guidance. | 3 / 5 |
Workflow Clarity | There is no sequenced implementation workflow: only a rough two-stage progression (overview → "Read that file when the navigation tier above is insufficient"), no guidance for choosing among the three strategies, and no validation checkpoints ("Log Security Events" is a practice, not a verify step), fitting 'rough sequence present but many gaps; validation absent'. Not 1 because the content itself is coherent and navigation to detailed patterns is explicit. | 2 / 5 |
Progressive Disclosure | The body is an overview that delegates the bulk of detailed content to a single, clearly signaled, one-level-deep reference ("Detailed pattern documentation lives in `references/details.md`. Read that file..."), and that file exists with the promised worked patterns, fitting 'good structure; most content is appropriately placed'. Not 5 because the pointer does not enumerate what the reference covers (JWT, sessions, OAuth2, RBAC sections) and the inlined Core Concepts material overlaps with it. | 4 / 5 |
