spring-boot-skill
Build Spring Boot 4.x applications following the best practices. Use this skill: * When developing Spring Boot applications using Spring MVC, Spring Data JPA, Spring Modulith, Spring Security * To create recommended Spring Boot package structure * To implement REST APIs, entities/repositories, service layer, modular monoliths * To use Thymeleaf view templates for building web applications * To write tests for REST APIs and Web applications * To write ArchUnit tests for testing architecture * To configure the recommended plugins and configurations to improve code quality, and testing while using Maven. * To use Spring Boot's Docker Compose support for local development * To create Taskfile for easier execution of common tasks while working with a Spring Boot application

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 a strong skill description that clearly defines its scope around Spring Boot 4.x development with comprehensive trigger terms and explicit 'Use this skill' guidance. It lists specific, concrete actions across multiple aspects of Spring Boot development (APIs, testing, architecture, tooling) making it easy for Claude to match against user requests. The description is well-structured with bullet points that cover both common and niche use cases.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description lists multiple specific concrete actions: creating package structures, implementing REST APIs, entities/repositories, service layers, modular monoliths, writing ArchUnit tests, configuring Maven plugins, using Docker Compose support, and creating Taskfiles. | 3 / 3 |
Completeness | Clearly answers both 'what' (build Spring Boot 4.x applications with specific technologies and patterns) and 'when' (explicit 'Use this skill:' clause with detailed bullet points covering multiple trigger scenarios). | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'Spring Boot', 'Spring MVC', 'Spring Data JPA', 'Spring Modulith', 'Spring Security', 'REST APIs', 'Thymeleaf', 'ArchUnit', 'Maven', 'Docker Compose', 'Taskfile'. These are all terms developers would naturally use when requesting help with Spring Boot development. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with a clear niche: Spring Boot 4.x specifically, with unique triggers like Spring Modulith, ArchUnit tests, Taskfile creation, and Docker Compose support that distinguish it from generic Java or web development skills. | 3 / 3 |

Implementation
72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill excels as a routing/index document with outstanding progressive disclosure and conciseness. However, it sacrifices some actionability by providing zero inline examples or quick-start guidance, and the workflow could benefit from explicit sequencing or a decision tree to help Claude understand when and in what order to apply each reference. The conditional language ('If Thymeleaf is used...', 'If building a REST API...') is helpful for context-dependent guidance.
Suggestions
Add a brief quick-start section at the top with a minimal concrete example (e.g., a skeleton Spring Boot 4.x project structure or a single command to bootstrap a project) to improve actionability.
Consider adding an explicit numbered workflow or decision tree showing the recommended order of operations when building a new Spring Boot application from scratch, including validation checkpoints (e.g., 'verify the app compiles after setting up Maven config before proceeding to code organization').
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is extremely lean — it's essentially a routing document with one-line descriptions pointing to reference files. No unnecessary explanations, no concepts Claude already knows. Every token serves a purpose. | 3 / 3 |
Actionability | The skill itself provides no concrete code, commands, or executable guidance — it entirely delegates to reference files. While the references likely contain actionable content, the skill body itself only describes what to do at a high level (e.g., 'Implement REST APIs with Spring MVC using...'). It's not vague, but it's not directly actionable either. | 2 / 3 |
Workflow Clarity | There is an implicit ordering (Maven config → package structure → JPA → service → REST → modulith → testing → Taskfile) that roughly follows a development workflow, but there's no explicit sequencing, no numbered steps, and no validation checkpoints. For a multi-faceted skill covering application development end-to-end, a clearer workflow with decision points would be beneficial. | 2 / 3 |
Progressive Disclosure | This is an excellent example of progressive disclosure — a concise overview with clearly signaled, one-level-deep references to specific topic files. Each section has a brief description and a direct link to the relevant reference document. Navigation is straightforward. | 3 / 3 |
