Conciseness

The ~500-line body is dominated by generic material Claude already knows: full React Query setup/useQuery/useMutation tutorials, basic fetch GET/POST, AbortController cancellation, and a NetInfo hook — with only a fraction being genuinely Expo-specific knowledge (expo/fetch preference, SecureStore, EXPO_PUBLIC_ build-time semantics). The When-to-Use list, Decision Tree, and Example Invocations sections also repeat the same routing information three times, matching 'noticeably verbose; several unnecessary explanations or padded sections' rather than the isolated trimmable excess of a 3.

Actionability

Guidance is mostly executable: copy-paste-ready TSX for error handling (ApiError class), retry with exponential backoff, SecureStore token wrapper, token refresh with single-flight promise, onlineManager/NetInfo wiring, and an env-configured API client. Minor gaps hold it below 5: `isTokenExpired`/`refreshToken` are referenced but never defined, and 'Queue requests -> React Query persistence' names offline persistence without showing it (no asyncStoragePersister).

Workflow Clarity

The Decision Tree sequences every entry point (route-level loading, caching, auth, offline, env config) to a concrete recommended approach, giving clear routing. However, 'Debugging network failures' is promised in When to Use with no corresponding diagnostic steps, and there are no validation checkpoints — acceptable here since nothing is destructive/batch, so this is 'clear sequence with most checkpoints present; minor gaps' rather than a 5.

Progressive Disclosure

The reference that exists is well signaled: an annotated one-level-deep pointer ("references/expo-router-loaders.md — Route-level data loading with Expo Router loaders (web, SDK 55+)"), a decision tree that routes to it, and consistent path citations. But that file does not exist in the bundle (there is no references/ directory), so the pointer is broken rather than a 'minor organization gap', and the ~480-line inline bulk of generic React Query/fetch tutorials is exactly the 'content that should be separate is inline' pattern of the 3 anchor — sitting between anchors 3 and 4, the broken file pulls it down to 3.

Specificity

The description enumerates several specific concrete capabilities — "fetch API, React Query, SWR, error handling, caching, offline support, and Expo Router data loaders (useLoaderData)" — but these are topic/technology enumerations under a generic "Covers..." rather than the concrete verb-actions in the 5 anchor ("Extract text and tables... fill forms, merge documents"), and it never names the Expo/React Native stack it targets, a minor coverage gap.

Completeness

It explicitly answers both questions: "Use when implementing or debugging ANY network request, API call, or data fetching" gives concrete when-triggers, and "Covers fetch API, React Query, SWR, error handling, caching, offline support, and Expo Router data loaders" gives a clear what. This matches the 5 anchor's pattern of an explicit what-list followed by a concrete 'Use when' clause.

Trigger Term Quality

Strong natural keywords users would actually say: "network request", "API call", "data fetching", "error handling", "caching", "offline support", plus library names (React Query, SWR, useLoaderData). A few common natural phrasings are missing (e.g. "HTTP request", "REST API", "axios"), which keeps it below the comprehensive-synonym coverage of the 5 anchor.

Distinctiveness Conflict Risk

"ANY network request, API call, or data fetching" is a very broad trigger that would fire for networking work in any stack (backend HTTP clients, web apps, curl usage), creating real overlap risk with generic fetch/API skills. The named libraries (React Query, SWR, Expo Router) do add distinctiveness, but the stack is never stated, so it sits at 'somewhat specific but could still overlap with similar skills' rather than the clear niche of a 4 or 5.
