Create an auto-imported composable following docs/ARCHITECTURE.md section 4.4.

Composable: $ARGUMENTS

Steps

1. Read docs/ARCHITECTURE.md section 4.4.

2. Determine the type:

   • Query (data reading) -> useAsyncData + service + adapter
   • Mutation (write/delete) -> function + service + refreshNuxtData
   • Pure logic (no API) -> refs + computed + lifecycle
   • Shared state (SSR-safe) -> useState for simple, Pinia for complex

3. Create the composable in composables/use[Name].ts (auto-imported) or modules/[feature]/composables/use[Name].ts:

   • Required use prefix
   • Parameters with Ref<T> for reactivity
   • Reactive key for useAsyncData
   • watch option for auto-refetch
   • Adapter in transform option
   • Return type with refs/computed

4. Connect the layers: service -> adapter -> useAsyncData

5. Validate: nuxi typecheck
