502 Frameworks Micronaut REST

Use when you need to design, review, or improve REST APIs with Micronaut — including @Controller routes, HTTP status codes, DTOs, Bean Validation, exception handlers, pagination, idempotency, ETag/If-Match, caching headers, versioning, contract-first OpenAPI (OpenAPI Generator), optional runtime OpenAPI via micronaut-openapi, and security annotations. This should trigger for requests such as Review or improve Micronaut @Controller REST APIs; Add validation, error handling, or align controllers with the OpenAPI contract on Micronaut HTTP layer.

Micronaut REST API Guidelines

Apply REST design principles for Micronaut HTTP applications.

What is covered in this Skill?

Semantic HTTP with @Get/@Post/@Put/@Patch/@Delete and HttpResponse status control
Resource-oriented paths and stable DTO contracts
@Valid on request bodies with Bean Validation
Centralized error mapping (ExceptionHandler / problem JSON when applicable)
Pagination with Pageable and bounded sizes
OpenAPI contract file (API-first) and OpenAPI Generator for server stubs
Security annotations (@Secured) on sensitive routes
Idempotency-Key for retried writes
ETag / If-Match for optimistic concurrency
Cache-Control discipline
API versioning patterns
ISO-8601 time types in DTOs

Scope: Apply recommendations based on the reference rules and good/bad code examples.

Constraints

Compile before REST refactors; verify after.

MANDATORY: Run ./mvnw compile or mvn compile before applying any change
SAFETY: If compilation fails, stop immediately
VERIFY: Run ./mvnw clean verify or mvn clean verify after applying improvements
BEFORE APPLYING: Read the reference for detailed rules and examples
EDGE CASE: If request scope is ambiguous, stop and ask a clarifying question before applying changes
EDGE CASE: If required inputs, files, or tooling are missing, report what is missing and ask whether to proceed with setup guidance

When to use this skill

Review or improve Micronaut @Controller REST APIs
Add validation, error handling, or align controllers with the OpenAPI contract on Micronaut HTTP layer

Workflow

Read reference and assess project context

Read references/502-frameworks-micronaut-rest.md and inspect the current project setup before proposing changes.

Gather scope and decide target improvements

Identify requested outcomes, constraints, and the minimum safe set of changes to apply.

Apply framework-aligned changes

Implement or refactor configuration/code following the reference patterns and project conventions.

Run verification and report results

Execute appropriate build/tests and summarize what changed, what was verified, and any follow-up actions.
