The body is mostly efficient and assumes Claude's knowledge, but the 'When to use this skill' section repeats the same five trigger scenarios already in the description, adding redundancy that could be trimmed.

Concrete commands are present (./mvnw compile, mvn clean verify) and annotations are named, but the body itself contains no executable code examples for repositories/entities/queries, and step 3 ('Implement or refactor ... following the reference patterns') is relatively abstract, deferring specifics to the reference.

The 4-step workflow is clearly sequenced with explicit validation checkpoints (MANDATORY compile before changes, SAFETY stop-on-failure, VERIFY clean verify after) forming a compile-fix-verify feedback loop.

The body is a concise overview that points to a single, clearly-signaled one-level-deep reference (references/512-frameworks-micronaut-data.md, verified to exist) with appropriate content split and easy navigation.

Lists multiple concrete capabilities (@MappedEntity, CrudRepository/PageableRepository, @Query, @Transactional, projections, @Version, @MicronautTest), which would rate 3, but the second-person phrasing 'Use when you need data access' is penalized by one point per the voice guideline.

It answers both 'what' (data access with Micronaut Data plus a concrete annotation list) and 'when' with an explicit 'Use when...' clause and enumerated trigger scenarios.

The explicit trigger list ('Review or implement Micronaut Data repositories and entities; Add transactions, pagination, or projections...') covers natural phrases a user would say, with good variation across entity, repository, transaction, pagination, projection, and optimistic-locking requests.

The Micronaut Data niche is distinct, and it explicitly disambiguates from the sibling skill ('For raw java.sql access without generated repositories, use @511-frameworks-micronaut-jdbc'), making mis-triggering unlikely.
