Conciseness

The body is lean and assumes Claude's competence — it never explains what Redux, React Query, nuqs, or Zustand are, and every section consists of directives, constraints ("Keep payload small (e.g. Chrome ~2k chars)", "up to ~1.5–2MB"), or code rather than background. Re-reading anchor 4 ("minor instances of over-explanation"), nothing here explains concepts Claude already knows; the classification table and checklist each earn their tokens.

Actionability

Concrete, near-executable guidance throughout: exact APIs (`useQueryState('param', parseAsString.withDefault('…'))`, `useDashboardStore(state => state.isDashboardLocked)`), named plugin config (`plugin:zustand-rules/recommended`), and cache options (`refetchOnMount: false`, `staleTime`). Not anchor 5 because several snippets contain ellipsis placeholders (`useQuery(...)`, `useMemo(() => ({ ... })`)`) and the nuqs "Before" example is malformed pseudocode (`const [page, setPage] = useDispatch(...)`), so examples are not fully copy-paste ready.

Workflow Clarity

Clear sequence: classify state first ("Before changing code, classify what the state represents"), then per-target migration steps, then a consolidating checklist including removal items ("Remove old Redux slices / Context providers and all dispatches/consumers"). Not anchor 5 because there is no explicit validation step after migration (e.g., typecheck or grep for remaining dispatches/usages); the checklist is a to-do list rather than a verify-fix-retry loop. The destructive/batch cap is not applied since this is git-recoverable code refactoring, not the document/DB/batch category the rubric names.

Progressive Disclosure

The body is well-sectioned and keeps SKILL.md at overview size, and it signals deeper material ("Detailed patterns and rationale: [reference.md](reference.md)"), but that file does not exist in the bundle — the link dangles, so the promised detail is unreachable (the linked project rule `.claude/rules/frontend-state.md` is likewise absent). Per the guideline to score against the actual bundle structure, this lands at anchor 3 (references present but not usable) rather than 4.

Specificity

Concrete actions with an explicit mapping: "Migrate Redux or React Context to the correct state option (React Query for server state, nuqs for URL/shareable state, Zustand for global client state)" — third person, no fluff. Not anchor 5 because the skill also migrates local state to useState/useReducer (body section 5), which the description omits — a minor coverage gap placing it between anchors 4 and 5.

Completeness

Explicitly answers both questions: what ("Migrate Redux or React Context to the correct state option (React Query for server state, nuqs for URL/shareable state, Zustand for global client state)") and when ("Use when refactoring away from Redux/Context, moving state to the right store, or when the user asks to migrate state management") with concrete trigger phrases. Clear anchor 5; anchor 4's 'when could be more explicit' does not apply.

Trigger Term Quality

Comprehensive natural terms users would actually say: "Redux", "React Context", "refactoring away from Redux/Context", "moving state to the right store", "migrate state management", plus the target library names (React Query, nuqs, Zustand). Matches anchor 5's bar for synonyms and natural phrasing; nothing common is missing.

Distinctiveness Conflict Risk

Clear niche — migrating away from Redux/Context to three named libraries — with triggers anchored to migration/refactoring language, so it is unlikely to fire for general React, styling, or data-fetching skills. Minimal conflict risk, matching anchor 5.
