Conciseness

The body is entirely directive with zero filler — e.g. "Connect the layers: service -> adapter -> useAsyncData" and "Validate: `nuxi typecheck`" — and never explains concepts Claude already knows (what composables, refs, or useAsyncData are). Every token earns its place, matching the lean anchor exactly.

Actionability

Gives concrete, executable guidance: exact file paths ("composables/use[Name].ts" or "modules/[feature]/composables/use[Name].ts"), specific options ("Reactive key for useAsyncData", "`watch` option for auto-refetch", "Adapter in `transform` option"), and a runnable validation command ("nuxi typecheck"). Not level 5 because there is no example composable signature/template and key details are delegated to the external docs/ARCHITECTURE.md section 4.4; not level 3 because the guidance is specific and executable rather than pseudocode or high-level hints.

Workflow Clarity

Five clearly numbered steps in a sound order — read the architecture doc, classify the composable type, create the file, connect layers, validate — with an explicit checkpoint ("Validate: `nuxi typecheck`"). Not level 5 because there is no feedback loop for error recovery (what to do when typecheck fails); not level 3 because the validation step is explicit and correctly sequenced, not implicit.

Progressive Disclosure

The skill is under 50 lines, cleanly organized under a "## Steps" section, and delegates detail via a single clearly-signaled one-level-deep reference ("docs/ARCHITECTURE.md section 4.4"); no bundle files exist to split further. This matches the simple-skill exception: well-organized sections with no nested references.

Specificity

The description states one concrete action — "creates an auto-imported composable with useFetch/useAsyncData" — which names the domain and specific APIs but does not list several distinct actions. It is above level 2 (the action and technologies are concrete, not generic) but below level 4 (no multi-action coverage like query/mutation/shared-state handling).

Completeness

Both questions are answered explicitly: what ("creates an auto-imported composable with useFetch/useAsyncData") and when ("Use when adding server state management or shared logic"). Not level 5 because the when-clause misses obvious trigger phrasings such as "create a composable" or "data fetching"; not level 3 because the when is explicit with concrete triggers, not merely implied.

Trigger Term Quality

Includes natural, domain-appropriate trigger phrases — "server state management", "shared logic" — plus specific API names ("useFetch/useAsyncData") that users would mention. Not level 5 because common variations like "data fetching", "shared state", "reactive", or "Pinia" are absent; not level 3 because coverage goes well beyond a single generic keyword.

Distinctiveness Conflict Risk

"auto-imported composable" and "useFetch/useAsyncData" pin the skill to a clear Nuxt niche with distinct triggers. Not level 5 because "server state management" and "shared logic" could also plausibly trigger closely related skills (e.g., a Pinia store-creation skill); not level 3 because the what-clause is highly specific to composable creation.
