Quality

Content

75%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A highly actionable, well-structured reference with copy-paste examples across SWR's API surface. Main weakness is conciseness: a hard-coded version number and some explanatory padding that Claude does not need.

Suggestions

Remove the hard-coded version number ('latest: 2.4.1') or move it to a dedicated version/deprecated section so the skill does not go stale.

Trim the 'You are an expert in SWR v2...' opener and the stale-while-revalidate concept definition; assume Claude knows the caching strategy.

Consider splitting the full subscription/error-retry reference into a referenced file if the skill grows, to keep SKILL.md a lean overview.

Dimension	Reasoning	Score
Conciseness	Mostly efficient with copy-paste examples, but includes stale time-sensitive info ('latest: 2.4.1'), an 'You are an expert' framing line, and a stale-while-revalidate concept explanation Claude already knows.	3 / 5
Actionability	Fully executable, copy-paste-ready code covering the common cases (useSWR, mutation, infinite, subscription, optimistic updates, error retry) with concrete options and return values.	5 / 5
Workflow Clarity	Well-organized into clear per-API sections with a 'Key Rules' guardrails list; no destructive/batch workflow so no validation cap applies, though there is no explicit multi-step sequence with checkpoints.	4 / 5
Progressive Disclosure	Single self-contained file with clear section headers and a navigation-like structure; no bundle files exist, and the inline reference content is reasonably scoped for a focused library skill.	4 / 5

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, specific description that clearly communicates both the skill's purpose and its activation triggers with concrete SWR-specific scenarios. Minor room to add a few more user-natural synonyms for trigger terms.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'client-side data fetching, caching, revalidation, mutations, optimistic UI, pagination, or infinite loading' — giving comprehensive coverage of SWR's capabilities.	5 / 5
Completeness	Explicitly states what the skill provides ('SWR data-fetching expert guidance') and gives a concrete 'Use when...' clause enumerating trigger scenarios, answering both what and when.	5 / 5
Trigger Term Quality	Good natural-term coverage (data fetching, caching, revalidation, mutations, optimistic UI, pagination, infinite loading, SWR, React), but missing common synonyms or variant phrasings a user might say.	4 / 5
Distinctiveness Conflict Risk	Scoped to a named library (SWR) with distinctive data-fetching triggers, giving it a clear niche with minimal overlap against other skills.	5 / 5
	Total	19 / 20 Passed
