Conciseness

Every bullet carries non-obvious, repo-specific knowledge (void preload rejection semantics, skipToken producing a missing-query-function error, the SuperJSON/pending-dehydration dependency in trpc/query-client.ts) with zero padding and no explanation of concepts Claude already knows. Anchor 4's 'minor instances of over-explanation' does not apply — nothing here could be trimmed without losing information.

Actionability

The snippet is complete and copy-paste ready (exact imports from @/trpc/preload-query and @/trpc/server, real procedure trpc.settings.getModelPreferences), and the bullets give executable API shapes for both normal (queryClient.query(trpc.foo.bar.queryOptions(...))) and infinite queries (infiniteQueryOptions with cursor and getNextPageParam). This matches 'fully executable; specific examples cover the common cases' — including guarding conditionals — with no pseudocode.

Workflow Clarity

This is a single-purpose pattern skill (~24 lines) and the core action is unambiguous: get the request-cached client, void the preload, render consumers beneath the matching hydration boundary, preserving awaited settings preloads and isolated clients. The rubric's simple-skill exception applies and there is no destructive or batch operation, so the workflow-clarity cap for missing validation does not apply.

Progressive Disclosure

The skill is under 50 lines with no need for external references (none of references/, scripts/, assets/ exist), organized as prose, bullets, a code example, and a dependency caveat. Per the rubric guideline for short skills without external references, well-organized structure alone merits the top score; the one file mention (trpc/query-client.ts) is an in-repo path, not a broken bundle reference.

Specificity

Concrete phrases like 'lazy-prefetch pattern without blocking server rendering', 'prefetching tRPC queries in Next.js Server Components', and 'changing query dehydration and hydration behavior' name the domain and several specific behaviors, matching anchor 4 ('several specific actions; minor gaps'). It falls short of anchor 5 because the what-clause names the pattern rather than enumerating its full set of concrete actions.

Completeness

It explicitly answers what ('Use the ChatJS React Query v5 lazy-prefetch pattern without blocking server rendering') and when with a concrete 'Use when' clause covering both trigger scenarios (prefetching tRPC queries in Server Components, changing dehydration/hydration behavior in apps/chat). This matches anchor 5's both-what-and-when with concrete trigger phrases; anchor 4's 'when could be more explicit' does not apply.

Trigger Term Quality

Good natural-keyword coverage: 'React Query v5', 'prefetching tRPC queries', 'Next.js Server Components', 'dehydration and hydration'. It sits at anchor 4 rather than 5 because common variations a user might say — 'RSC', 'server-side prefetch', 'SSR', 'query cache' — are missing.

Distinctiveness Conflict Risk

The niche is sharply defined — lazy-prefetch + tRPC + Server Components + apps/chat hydration behavior — so it would not trigger for unrelated React Query or Next.js skills. Minimal conflict risk, matching anchor 5.
