Content

82%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 well-structured React patterns reference with abundant executable examples and clear decision trees. It is conciser than most pattern catalogs and uses one-level cross-links well, with only minor trimming and structural-split opportunities preventing top scores.

DimensionReasoningScore

Conciseness

The body is a lean, code-driven catalog where most prose (e.g. 'Derived state in useEffect adds a render cycle') earns its place; minor over-explanation of mechanics Claude already knows (React.memo equality-check behavior) keeps it just below a 5.

4 / 5

Actionability

Provides copy-paste-ready TSX for the common cases (Cart derivation, RSC boundaries, useActionState forms, useDebounce, useOptimistic) plus concrete decision trees and a data-fetching matrix — fully executable guidance.

5 / 5

Workflow Clarity

Decision trees (state location) and the data-fetching matrix give clear sequenced guidance with no destructive/batch operations requiring validation caps; it is a reference catalog rather than a multi-step process, so it stops short of the explicit validate→fix→retry pattern that defines a 5.

4 / 5

Progressive Disclosure

No bundle files exist, but the body is well-sectioned and cross-links to sibling materials (rules/react/hooks.md, accessibility/SKILL.md, react-testing) are one level deep and clearly signaled; minor organization gaps (some catalog content could live in reference files) keep it at 4.

Description

88%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 names concrete React 18/19 capabilities and provides an explicit 'Use when' trigger in third person. Minor gaps in trigger synonyms/file extensions and some overlap risk with sibling React skills keep it just below the top anchor on two dimensions.

DimensionReasoningScore

Specificity

Lists multiple concrete capabilities — 'hooks discipline, server/client component boundaries, Suspense + error boundaries, form actions, data fetching, state management decision trees, and accessibility-first composition' — giving comprehensive coverage rather than a single domain label.

5 / 5

Completeness

Explicitly answers both 'what' (the enumerated React 18/19 patterns) and 'when' ('Use when writing or reviewing React components') with a concrete trigger phrase.

5 / 5

Trigger Term Quality

Includes natural terms a user would say ('writing or reviewing React components', hooks, Suspense, form actions, data fetching), but omits synonyms and file extensions like JSX/TSX/.tsx that would push it to a 5.

4 / 5

Distinctiveness Conflict Risk

The 'React 18/19 patterns' framing is a clear niche, but the broad trigger 'writing or reviewing React components' risks overlap with closely related sibling skills (react-performance, react-testing) referenced in the body.
