75%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, token-efficient reference skill: prescriptive priority-tagged rules, executable code across four cache layers, and actionable anti-pattern remedies. The main gaps are a missing code example for the highest-priority invalidation rules and code examples that push the single file toward a size where splitting would help.
Suggestions
Add a short code example for event-driven invalidation (e.g., deleting/versioning cache keys on write/update), since it is the skill's P0-MUST topic but the only major area without an executable example.
Trim the code examples to their minimal instructive core (e.g., drop the Express/Hono boilerplate around the Cache-Control headers) to tighten conciseness.
Consider moving the per-layer code examples into a references/ file with the layer table remaining in SKILL.md, so the core guidance loads lean while detail stays one level deep.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and prescriptive with priority-tagged bullets ([P0-MUST]/[P1-SHOULD]/[P2-MAY]) and never explains concepts Claude already knows, but the four full code examples (especially the TanStack configuration block) are slightly long and could be trimmed to reach anchor 5. | 4 / 5 |
Actionability | Mostly executable guidance: real code for LRU-with-TTL, Redis stale-while-revalidate, Express cache headers, and TanStack Query, plus a concrete layer-selection table and key formats. It misses anchor 5 because the P0-MUST invalidation rules have no corresponding code example — a minor gap in covering the common cases. | 4 / 5 |
Workflow Clarity | Precedence is unambiguous via priority tags, the layering order is explicit ("check memory → Redis → origin. Write-through on miss"), and each anti-pattern carries a concrete "Instead:" remedy. No destructive or batch operations, so no validation cap applies, but there is no explicit multi-step sequence or checkpoint guidance to reach anchor 5. | 4 / 5 |
Progressive Disclosure | A single self-contained file with no bundle, organized into clearly headed sections that are easy to navigate. It fits anchor 4 (good structure, content appropriately placed for its size) rather than 5, since the body exceeds the under-50-line simple-skill exception and the code examples could conceivably live in separate reference files. | 4 / 5 |
