Lists multiple specific concrete actions and concepts: Micronaut.run bootstrap, @Singleton/@Prototype, @Factory beans, @ConfigurationProperties, environments, @Requires, @Controller vs services, @Scheduled, graceful shutdown, @ExecuteOn for blocking work, and Jakarta-consistent APIs.

Explicitly answers both what (the list of Micronaut concepts and features) and when ('Use when building or reviewing Micronaut applications') with a clear trigger clause at the beginning.

Includes 'Micronaut applications' and specific annotations like @Singleton, @Controller, @Scheduled which are relevant but highly technical. Missing common user phrases like 'dependency injection', 'microservices', 'REST API', or simpler terms users might naturally say.

Highly distinctive with clear Micronaut-specific terminology and annotations. The explicit mention of 'Micronaut' and framework-specific concepts like @ConfigurationProperties, @Requires, and Micronaut.run bootstrap make it unlikely to conflict with generic Java or other framework skills.

The skill is lean and efficient, using bullet points to list covered topics without explaining what Micronaut is or how DI works. Every line serves a purpose and assumes Claude's competence with Java frameworks.

The skill provides clear constraints and verification commands (./mvnw compile, ./mvnw clean verify), but lacks concrete code examples in the body itself. All detailed guidance is deferred to the reference file, making the skill more of a pointer than executable guidance.

Clear workflow with explicit validation checkpoints: compile before changes, stop if compilation fails, verify after changes. The MANDATORY/PREREQUISITE/SAFETY/VERIFY structure provides an unambiguous sequence with feedback loops.

Excellent structure with a concise overview, clear scope definition, constraints section, and a single well-signaled reference to detailed documentation. One-level-deep reference pattern is properly implemented.
