Use when you need to design, review, or improve REST APIs with Spring Boot — including HTTP methods, resource URIs, status codes, DTOs, versioning, deprecation and sunset headers, content negotiation (JSON and vendor media types), ISO-8601 instants in DTOs, pagination/sorting/filtering, Bean Validation at the boundary, idempotency, ETag concurrency, HTTP caching, error handling, security, contract-first OpenAPI (OpenAPI Generator), controller advice, and problem details for errors. This should trigger for requests such as Review Java code for Spring Boot REST API; Apply best practices for Spri

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Java REST API Design Principles Apply REST API design principles for Spring Boot applications. **What is covered in this Skill?** - HTTP methods (GET, POST, PUT, PATCH, DELETE) — semantic consistency - Resource URI design - HTTP status codes - Request/response DTOs with lean contracts - API versioning (URI, header, or media type — applied consistently) - Bean Validation at the boundary (@Valid/@Validated on controller inputs, 400 on failure) - Pagination, sorting, and filtering (Page/Pageable with caps) - ISO-8601 instants with offset (OffsetDateTime, Instant) in JSON contracts - Content negotiation (JSON default; vendor media types when meaningful) - Idempotency-Key support for POST creates; 409 Conflict for collisions - ETag concurrency with If-Match/If-None-Match; 412 Precondition Failed / 304 Not Modified - HTTP caching discipline (Cache-Control, ETag, Last-Modified) - Deprecation and sunset headers (Deprecation, Sunset, Link rel="successor-version)" - Error handling - API security (TLS, authentication, authorization, input validation) - API contract: OpenAPI file as source of truth for API-first (OpenAPI Generator) - Controller advice and problem details (RFC 7807) **Scope:*

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill 302-frameworks-spring-boot-rest --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
