302-frameworks-spring-boot-rest

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 Spring Boot REST API in Java code; Design Spring Boot REST controllers and DTOs; Add Problem Details error responses in Spring Boot REST; Improve pagination validation or idempotency in Spring APIs.

Quality

Content

85%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured overview skill with clear sequencing, explicit validation checkpoints, and clean single-level progressive disclosure. The weakest area is actionability, since the workflow steps are abstract and concrete patterns live only in the reference.

Suggestions

Add one small concrete example or a minimal code snippet to the workflow (e.g., a skeleton @RestController with @Valid and Pageable) so the body is actionable on its own, not just by reference.

Tighten the 'What is covered' and 'When to use' lists, which largely restate the description's topic catalog and trigger phrases, to reduce redundancy.

DimensionReasoningScore

Conciseness

The body is a lean overview that assumes Claude's competence (no explanation of what REST or Spring Boot is) and points to a single reference file rather than restating detail inline.

3 / 3

Actionability

Concrete build commands are present ('./mvnw compile', 'mvn clean verify'), but the workflow steps are abstract ('Implement or refactor configuration/code following the reference patterns and project conventions') and defer all executable guidance to the reference file.

2 / 3

Workflow Clarity

The workflow is a clear 4-step sequence with explicit validation checkpoints (MANDATORY compile-before-change, SAFETY stop-on-failure, VERIFY clean verify after), providing a real feedback loop.

3 / 3

Progressive Disclosure

The body is a concise overview pointing to a single, well-signaled, one-level-deep reference (references/302-frameworks-spring-boot-rest.md) that exists in the bundle, with no nested indirection.

Description

90%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A comprehensive, well-triggered description that clearly states both capabilities and use-conditions for a Spring Boot REST API skill. The main weakness is the second-person voice, which the rubric penalizes on specificity.

Suggestions

Rewrite the opening in third person to avoid the second-person 'Use when you need to...' (e.g., 'Use when designing, reviewing, or improving REST APIs with Spring Boot') so specificity is not capped by voice.

Trim the long mid-sentence topic catalog, which borders on keyword stuffing; the trigger phrase list already conveys breadth.

DimensionReasoningScore

Specificity

The description lists many concrete actions and topics (HTTP methods, DTOs, idempotency, ETag concurrency, problem details), which would warrant a 3, but it is written in second person ('Use when you need to design...') and the rubric penalizes second-person voice by reducing specificity by one level.

2 / 3

Completeness

It clearly answers both what (design/review/improve REST APIs with Spring Boot, with a detailed topic catalog) and when via an explicit 'Use when...' clause plus 'This should trigger for requests such as...'.

3 / 3

Trigger Term Quality

It provides explicit, natural trigger phrases users would actually say ('Review Java code for Spring Boot REST API', 'Apply best practices for Spring Boot REST API in Java code', 'Add Problem Details error responses in Spring Boot REST').

3 / 3

Distinctiveness Conflict Risk

It targets a clear, narrow niche (Spring Boot REST APIs specifically) with distinct triggers, making it unlikely to fire for unrelated skills.
