spring-boot-engineer

Generates Spring Boot 3.x configurations, creates REST controllers, implements Spring Security 6 authentication flows, sets up Spring Data JPA repositories, and configures reactive WebFlux endpoints. Use when building Spring Boot 3.x applications, microservices, or reactive Java applications; invoke for Spring Data JPA, Spring Security 6, WebFlux, Spring Cloud integration, Java REST API design, or Microservices Java architecture.

Discovery

100%

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

This is an excellent skill description that clearly articulates specific capabilities within the Spring Boot ecosystem, provides comprehensive trigger terms covering the major Spring sub-frameworks, and includes an explicit 'Use when' clause with well-chosen scenarios. It uses proper third-person voice throughout and is both concise and information-dense, making it easy for Claude to select this skill precisely when needed.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: generates configurations, creates REST controllers, implements Spring Security 6 authentication flows, sets up Spring Data JPA repositories, and configures reactive WebFlux endpoints.

3 / 3

Completeness

Clearly answers both 'what' (generates configurations, creates controllers, implements security flows, sets up repositories, configures WebFlux) and 'when' with an explicit 'Use when...' clause listing specific trigger scenarios like building Spring Boot 3.x applications, microservices, or reactive Java applications.

3 / 3

Trigger Term Quality

Excellent coverage of natural terms users would say: 'Spring Boot 3.x', 'REST controllers', 'Spring Security 6', 'Spring Data JPA', 'WebFlux', 'microservices', 'reactive Java', 'Spring Cloud', 'Java REST API', providing strong keyword coverage across the Spring ecosystem.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive with a clear niche in the Spring Boot 3.x / Spring ecosystem. The specific version numbers (Spring Boot 3.x, Spring Security 6) and technology-specific terms (WebFlux, Spring Data JPA, Spring Cloud) make it very unlikely to conflict with generic Java or web development skills.

Implementation

77%

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

This is a well-structured Spring Boot skill with excellent actionability—every code example is executable and follows modern best practices. The workflow includes proper validation checkpoints and error recovery loops. The main weakness is that the SKILL.md tries to serve as both an overview and a detailed quick-start tutorial, making it longer than necessary; some of the inline code examples could be moved to reference files to improve progressive disclosure and conciseness.

Suggestions

Consider moving some Quick Start code examples (e.g., GlobalExceptionHandler, Test Slice) to the relevant reference files (web.md, testing.md) and keeping only the Entity→Repository→Service→Controller chain inline to reduce token footprint.

Trim the Quick Start to 2-3 representative layers and link to a full example in a reference file, keeping SKILL.md as a concise overview.

DimensionReasoningScore

Conciseness

The Quick Start section is quite lengthy with full code examples for every layer (entity, repository, service, controller, DTO, exception handler, test). While each example is useful, the combined volume is substantial. The constraints tables are efficient, but the overall content could be tightened—e.g., the exception handler and test slice could be deferred to reference files.

2 / 3

Actionability

All code examples are fully executable, copy-paste ready Java with correct annotations, proper imports implied, and realistic patterns. The constraints tables give specific correct/incorrect patterns. The workflow steps include concrete commands like `./mvnw test` and `/actuator/health`.

3 / 3

Workflow Clarity

The Core Workflow has a clear 6-step sequence with explicit validation checkpoints and feedback loops: security step includes 'if compilation or tests fail: review, fix, re-run'; testing step includes 'if tests fail: review stack trace, isolate, fix, re-run'; deploy step includes 'if health is DOWN: check components, resolve, re-validate'. This covers destructive/risky operations well.

3 / 3

Progressive Disclosure

The reference table with 5 topic-specific files (web.md, data.md, security.md, cloud.md, testing.md) is well-structured with clear 'Load When' guidance. However, no bundle files were provided, so these references cannot be verified. Additionally, the Quick Start section inlines a large amount of content (7 code blocks) that could partially be deferred to the web.md or data.md references, making the SKILL.md itself heavier than ideal for an overview.
