Quick Review

Excellent Spring Boot skill with comprehensive coverage of Spring Boot 3.x ecosystem. The description clearly indicates when to invoke (JPA, Security 6, WebFlux, Cloud), and the skill provides strong task knowledge through a well-organized reference system covering web, data, security, cloud, and testing domains. The structure is exemplary with a concise SKILL.md that indexes detailed references in separate files. Clear constraints (MUST/MUST NOT) and a 6-step workflow provide actionable guidance. Novelty is solid as Spring Boot's extensive ecosystem and enterprise patterns would require significant token usage for a CLI agent to handle alone. Minor improvement areas: the description could be slightly more specific about reactive vs. imperative use cases, and the output template could specify more concrete code structure patterns. Overall, a well-designed skill that meaningfully reduces cost for Spring Boot development tasks.
