Conciseness

The body is lean and code-forward with no concept explanations Claude already knows. Two minor trims exist: the opening sentence repeats the frontmatter description almost verbatim, and the closing line about `dispatch`'s arguments restates the table row. Anchor 4 (minor over-explanation) fits better than anchor 5, where every token earns its place.

Actionability

Fully executable guidance: copy-paste-ready npm install commands for both Redux and Redux Toolkit paths, and a complete runnable TSX example (slice, store, adapter, StateProvider) that covers the common case, backed by a typed options table. Matches the top anchor.

Workflow Clarity

The usage example embeds an explicitly numbered 1-4 sequence (define slice → create store → create adapter → wrap in StateProvider). This is a simple, single, non-destructive integration task with an unambiguous single action, so the simple-skill exception applies and no validation checkpoint is needed.

Progressive Disclosure

No bundle files exist and none are needed: the skill is a single short file with well-organized sections (Installation, Usage, API) and the small options table inline. Per the rubric's simple-skill guidance, that merits the top score.

Specificity

The description names its domain ('Redux adapter for json-render's StateStore interface') and one concrete capability, but does not list several specific actions. This matches the anchor for 1-2 concrete actions without comprehensive coverage; anchor 4 requires several listed actions.

Completeness

It explicitly answers both parts: 'what' ('Redux adapter for json-render's StateStore interface') and 'when' ('Use when integrating json-render with Redux or Redux Toolkit for state management'). Third person, concrete trigger phrases — matches the top anchor exactly.

Trigger Term Quality

Natural terms users would say are present — 'Redux', 'Redux Toolkit', 'state management', plus the package name '@json-render/redux' (analogous to a file-extension trigger). A few natural variations ('store', 'global state', 'slice') are missing, so it is good rather than comprehensive coverage.

Distinctiveness Conflict Risk

A clear niche (json-render ↔ Redux state-backend integration) with distinct triggers combining both package names; it would not fire for generic Redux or generic state-management requests. Minimal conflict risk.
