creating-springboot-projects
Creates Java 25 and Spring Boot 4 project structures, scaffolds, and implementation starting points for new services, REST APIs, and modular backends. Use when the task is to initialize a Spring Boot project, choose an architecture, select Spring Boot 4 features, or apply the bundled templates and references in this skill. Do not use for migrating existing projects or for isolated JPA/repository work without broader project-creation context.

Quality
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 defines its scope (Java 25/Spring Boot 4 project scaffolding), provides explicit trigger conditions via a 'Use when' clause, and includes boundary-setting 'Do not use' guidance to minimize conflicts with adjacent skills. The description is concise yet comprehensive, using natural keywords and concrete actions throughout.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: creating project structures, scaffolding, implementation starting points, and specifies the domains (new services, REST APIs, modular backends). Also mentions architecture selection and template application. | 3 / 3 |
Completeness | Clearly answers both 'what' (creates project structures, scaffolds, implementation starting points for services/APIs/backends) and 'when' (explicit 'Use when' clause with triggers like initializing a project, choosing architecture, selecting features). Also includes a helpful 'Do not use' clause for boundary clarity. | 3 / 3 |
Trigger Term Quality | Includes strong natural keywords users would say: 'Java 25', 'Spring Boot 4', 'project structures', 'scaffolds', 'REST APIs', 'initialize a Spring Boot project', 'architecture', 'templates'. These cover common variations of how users would describe project creation tasks. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with a clear niche: Java 25 + Spring Boot 4 project creation specifically. The 'Do not use' clause explicitly excludes migration and isolated JPA work, further reducing conflict risk with related but different skills. | 3 / 3 |

Implementation
70%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 skill with excellent workflow clarity and progressive disclosure—it clearly sequences the project creation process and appropriately delegates detailed content to reference files and templates. Its main weaknesses are moderate verbosity in asset listings and a lack of concrete, executable examples (e.g., actual CLI commands for Spring Initializr, example placeholder substitution). The decision matrix for architecture selection is a strong practical element.
Suggestions
Add an executable example showing the actual Spring Initializr CLI command or curl request to generate a project, making Step 3 copy-paste ready.
Condense the asset file listings in Step 4 by grouping them more tightly (e.g., 'See assets/ directory—core templates: controller, repository, rich-entity, value-object, service-cqrs, exception-handler, flyway-migration, docker-compose; Boot 4 templates: http-service-client, api-versioning-config, etc.') to save tokens.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient and avoids explaining basic concepts Claude already knows (e.g., what Spring Boot is), but some sections are verbose—Step 3's dependency lists could be tighter, and the asset file listings in Step 4 take significant space that could be condensed into a reference to the assets directory with a brief categorization. | 2 / 3 |
Actionability | The skill provides a clear decision matrix, specific file references, and a structured output format, which is good. However, it lacks executable code or commands—there are no actual Spring Initializr CLI commands, no example of placeholder replacement in templates, and the guidance remains at the 'what to do' level rather than 'exactly how to do it' with copy-paste ready examples. | 2 / 3 |
Workflow Clarity | The six-step workflow is clearly sequenced with logical progression from assessment through architecture selection, setup, template application, architecture-specific customization, and handoff. Each step has explicit criteria and decision points, and Step 6 provides clear boundaries for when to delegate to other skills. | 3 / 3 |
Progressive Disclosure | The skill effectively serves as an overview that points to one-level-deep references (references/architecture-guide.md, references/spring-boot-4-features.md) and asset templates. Navigation is clearly signaled with a dedicated 'Reference loading guide' section, and content is appropriately split between the skill and its supporting files. | 3 / 3 |
