301-frameworks-spring-boot-core

Use when you need to review, improve, or build Spring Boot 4.0.x applications — including proper usage of @SpringBootApplication, component annotations (@Controller, @Service, @Repository), bean definition and scoping, configuration classes and @ConfigurationProperties (with @Validated), component scanning, conditional configuration and profiles, constructor injection, @Primary and @Qualifier for multiple beans of the same type, bean minimization, graceful shutdown, virtual threads, Jakarta EE namespace consistency, and scheduled tasks. This should trigger for requests such as Review Java code for Spring Boot application; Apply best practices for Spring Boot application in Java code; Improve Spring Boot configuration properties and beans; Review Spring Boot component scanning and profiles; Tune Spring Boot graceful shutdown or virtual threads.

Quality

Content

85%Weight 40%Scale 1-5

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

A tight, well-structured overview that assumes Claude's knowledge and routes detail to a single one-level-deep reference, with an explicit compile/verify validation loop and clarifying-question guardrails. Its only weakness is actionability: the body states commands but no executable Spring Boot code or annotation patterns, deferring all examples to the reference.

Suggestions

Add 1-2 short inline code/annotation snippets (e.g., a minimal @ConfigurationProperties + @Validated example or a constructor-injection snippet) so the most common changes are actionable without opening the reference.

Show a concrete @Primary/@Qualifier disambiguation example inline, since that is a frequently-needed and self-contained pattern.

Dimension	Reasoning	Score
Conciseness	The body is lean — it lists capability areas and a short workflow without explaining what Spring Boot or its annotations are, and offloads detail to the reference file; every section earns its place and assumes Claude's competence.	5 / 5
Actionability	It provides concrete commands (./mvnw compile, mvn clean verify) but no executable code or annotation examples in the body — concrete guidance is delegated to the reference file, so it instructs where to look rather than giving copy-paste-ready steps for the common cases.	3 / 5
Workflow Clarity	The Constraints section defines an explicit validation feedback loop (compile before changes -> stop on failure -> clean verify after -> ask on ambiguity/missing inputs), and the four-step Workflow sequences these checkpoints; validation is explicit with error-recovery guidance.	5 / 5
Progressive Disclosure	The body is an overview with well-signaled one-level-deep references (links to references/301-frameworks-spring-boot-core.md, which exists as a real bundle file), keeping detailed rules/examples out of SKILL.md; navigation is clear and shallow.	5 / 5

Description

88%Weight 40%Scale 1-5

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 thorough, third-person description that pairs concrete Spring Boot 4.0.x capabilities with explicit verbatim trigger phrases, satisfying both the 'what' and 'when' requirements. It is slightly long and lists feature names alongside actions, which keeps specificity just below the top anchor.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete capability areas (@SpringBootApplication, component annotations, @ConfigurationProperties with @Validated, @Primary/@Qualifier, graceful shutdown, virtual threads, scheduled tasks); coverage is comprehensive but some items are feature names rather than discrete actions, leaving minor gaps versus the score-5 anchor.	4 / 5
Completeness	Opens with 'Use when you need to review, improve, or build Spring Boot 4.0.x applications' (clear when) and enumerates concrete capabilities (clear what), then reinforces with 'This should trigger for requests such as...'; both what and when are explicit with concrete trigger phrases.	5 / 5
Trigger Term Quality	Embeds explicit verbatim trigger phrases ('Review Java code for Spring Boot application', 'Apply best practices for Spring Boot application in Java code') that match natural user requests, plus synonyms for each scenario; comprehensive natural-language coverage.	5 / 5
Distinctiveness Conflict Risk	The Spring Boot 4.0.x framing and specific annotations carve a clear niche distinct from generic Java skills, but it could overlap with sibling Spring skills (e.g., Spring Data/Security) in the same toolkit; minor overlap risk with closely related skills.	4 / 5
