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.
The SKILL.md body is a well-sequenced, specific, token-efficient set of instructions whose executable weight is carried by an excellent on-topic examples.md. However, the bundle's progressive disclosure is undermined by two reference files that contain off-topic content from a different skill (API design/error handling rather than caching), leaving the advertised 'full implementation guide' and 'comprehensive error patterns' effectively missing.
Suggestions
Rewrite references/implementation.md so it actually is the caching implementation guide the body promises — mapping the 9 instruction steps to concrete code (key generator, cache-aside middleware, tag invalidator, policy config) — or remove the link if examples.md is intended to carry that content.
Replace references/errors.md's off-topic entries (schema validation, authentication, rate limiting, database connections) with cache-specific error patterns that extend the body's error table, e.g. lock-based revalidation code for cache stampede and degraded-mode fallback for Redis connection failure.
Add per-stage verification checkpoints between implementation steps (e.g., 'verify X-Cache HIT/MISS with curl after step 3') rather than deferring all validation to the final test step.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense with specifics (per-category TTLs of 1 hour/5 minutes/30 seconds, header names, key composition rules, a compact error table) and does not explain concepts Claude already knows. Minor over-explanation remains: the Overview paragraph largely restates the description and the instructions, 'intelligent' is filler, and the prerequisite 'Understanding of data freshness requirements per endpoint' is unactionable padding. | 4 / 5 |
Actionability | Instructions are concrete and executable in design — deterministic key composition from method/path/sorted query/headers, X-Cache HIT/MISS semantics, specific TTL tiers, tag-based invalidation — and the referenced examples.md contains complete, runnable Express+Redis code covering every instruction. It stops short of anchor 5 because the body itself contains no code or commands and defers to two reference files that fail to deliver (see progressive disclosure). | 4 / 5 |
Workflow Clarity | Nine numbered steps form a coherent sequence from endpoint analysis through implementation to an explicit validation step (step 9: 'Write tests verifying cache hits, misses, invalidation correctness, TTL expiration, and stale-while-revalidate behavior'), so the destructive/batch cap does not apply. It falls short of anchor 5 because validation is a single terminal step rather than per-stage checkpoints or feedback loops (e.g., verify hit/miss behavior when each middleware lands). | 4 / 5 |
Progressive Disclosure | References are one level deep and clearly signaled in context, but scored against the actual bundle, two of the three are wrong-topic: the body promises 'the full implementation guide' in references/implementation.md, which is actually a generic API design guide (auth, rate limiting, OpenAPI docs — no caching), and 'comprehensive error patterns' in references/errors.md, which covers schema validation, authentication, and rate-limit errors rather than cache errors. Only examples.md is on-topic and complete, so the navigation the body advertises breaks down. | 3 / 5 |
