86%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-organized, highly actionable skill body with executable examples for three CDN vendors, a clearly sequenced canonical test, a useful anti-patterns table, and proper progressive disclosure to two real reference files. The main gap is an internal inconsistency where the flagship example uses fixed sleeps that the skill's own anti-patterns section warns against.
Suggestions
Make the canonical end-to-end example match the skill's own best practice: replace time.sleep(10)/time.sleep(30) with a poll loop on cf-cache-status until MISS (timeout 30s), as the anti-patterns table recommends.
Tighten the prose around code blocks (e.g., the 'Client-tier cache-control' and 'Parsing results' narrative) to lift conciseness — the tables already carry most of that information.
Consider narrowing the browser-tier trigger in the description (or noting the sibling browser-testing tools) to reduce overlap risk with a generic browser/E2E testing skill.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is mostly lean and code/table-dense, assuming Claude's competence (no 'what is a CDN' padding), but a few prose passages around the code blocks could be trimmed; efficient with minor over-explanation. | 4 / 5 |
Actionability | Fully executable, copy-paste-ready curl/Python/aws/CI examples cover the common cases (single-file purge, cache-tag, surrogate-key, CloudFront invalidation, end-to-end test, multi-region propagation). | 5 / 5 |
Workflow Clarity | The canonical purge test is explicitly numbered (origin write → verify old → purge → wait → verify fresh) with assert checkpoints, and the anti-patterns table supplies feedback-loop fixes — but the flagship example uses time.sleep(10)/sleep(30) while the anti-patterns section itself flags fixed sleeps as an anti-pattern, a minor internal inconsistency. | 4 / 5 |
Progressive Disclosure | Clear overview with well-signaled one-level-deep references — 'in references/browser-cache-control.md' and 'references/playwright-cache-recipes.md' — both of which exist as real bundle files, with browser-tier detail appropriately split out of the main body. | 5 / 5 |
