Conciseness

The ~30-line body is lean and assumes Claude's competence: no explanations of Vue Query or composables, every line instructs ("Parameters with `MaybeRef<T>` for reactivity", "Explicit `staleTime`"), and architecture detail is delegated to `docs/ARCHITECTURE.md` §4.4 rather than duplicated. This matches the anchor for every token earning its place.

Actionability

Guidance is mostly executable with concrete specifics: file path pattern `composables/use[Name].ts`, `MaybeRef<T>` params, reactive queryKey via `computed`, explicit `staleTime`, and the validation command `npx tsc --noEmit`. It stops short of anchor 5 because there is no copy-paste-ready composable code template covering the common Query case, leaving a minor gap.

Workflow Clarity

A clear five-step sequence (read spec, determine type, create composable, connect layers, validate) ends in an explicit validation checkpoint (`npx tsc --noEmit`), matching anchor 4. It is not anchor 5 because there is no explicit fix-and-retry feedback loop for validation failures; the batch/destructive cap of 3 does not apply since the operation creates a new file and validation is present.

Progressive Disclosure

This is a simple, single-purpose skill under 50 lines with no bundle files: a single "## Steps" section organizes the content, and the one external reference (`docs/ARCHITECTURE.md` §4.4) is clearly signaled and one level deep. Per the rubric's simple-skill guidance, this matches the top anchor.

Specificity

"creates Vue Query composable" is one concrete action, with "caching and error handling" as attributes of that artifact rather than separately listed actions, matching the anchor for naming a domain with 1-2 concrete actions. It falls short of anchor 4 because it does not enumerate several distinct actions, and is above anchor 2 because the action named is concrete rather than generic.

Completeness

Both parts are explicit: what ("creates Vue Query composable with caching and error handling") and when ("Use when adding server state management to a module"), matching anchor 4. It does not reach anchor 5 because the when-clause offers a single trigger rather than multiple concrete trigger phrases.

Trigger Term Quality

Natural terms users would say are present: "server state management", "Vue Query", "composable", "caching", "error handling" — good coverage matching anchor 4. It is not anchor 5 because common variations such as "data fetching", "useQuery/useMutation", or "API state" are missing.

Distinctiveness Conflict Risk

"Vue Query composable" combined with "server state management" carves out a clear niche with distinct triggers and minimal risk of firing for unrelated skills, matching anchor 5. Anchors 3-4 (overlap with similar skills) fit worse since the domain specificity is high.
