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. The bulleted list format effectively communicates both capabilities and trigger scenarios, covering REST APIs, testing, architecture, tooling, and deployment concerns. The specificity of version (4.x) and technology stack (Spring Modulith, ArchUnit, Thymeleaf, Maven) makes it highly distinguishable.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description lists multiple specific concrete actions: creating package structures, implementing REST APIs, entities/repositories, service layers, 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 capabilities listed) and 'when' (explicit 'Use this skill:' clause with detailed trigger scenarios covering development, testing, configuration, and tooling). | 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. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with a clear niche: Spring Boot 4.x specifically, with unique triggers like Spring Modulith, ArchUnit, Taskfile, and Docker Compose support that distinguish it from generic Java or web development skills. | 3 / 3 |

Implementation
57%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 excellent progressive disclosure and conciseness, but it sacrifices actionability entirely — the SKILL.md body contains no concrete code, commands, or executable guidance whatsoever. Without access to the bundle files, the skill provides no standalone value. Adding even minimal quick-start guidance (e.g., a Spring Boot project bootstrap command or a minimal application skeleton) would significantly improve its utility.
Suggestions
Add a 'Quick Start' section at the top with a concrete, executable example — e.g., a Spring Initializr command or minimal `@SpringBootApplication` class with one REST endpoint to give immediate actionable guidance.
Add a brief workflow overview section that explicitly sequences the development steps (e.g., '1. Configure Maven → 2. Set up package structure → 3. Define entities/repos → 4. Implement services → 5. Build APIs → 6. Write tests') with validation checkpoints like 'run tests after each layer'.
Include at least one concrete command example in the main skill (e.g., `./mvnw spring-boot:run` or `task build`) so the skill has standalone actionable value even before consulting references.
| 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.md itself contains zero executable code, no concrete commands, no examples, and no specific guidance. It is entirely composed of pointers to other files. Without the bundle files to evaluate, the content as written provides only vague direction like 'Implement REST APIs with Spring MVC using [reference].' | 1 / 3 |
Workflow Clarity | There is an implicit sequence (Maven config → package structure → JPA → service → REST APIs → modulith → testing → Taskfile) that follows a reasonable development workflow, but no explicit sequencing, no numbered steps, no validation checkpoints, and no guidance on when to use which sections together or in what order. | 2 / 3 |
Progressive Disclosure | This is a textbook example of progressive disclosure — a concise overview with well-signaled, one-level-deep references to specific topic files. Each section clearly names the concern and links to exactly one reference file. Navigation is straightforward. | 3 / 3 |
Total | 9 / 12 Passed |
