+  <description>Use when you need to review, improve, or build Spring Boot applications — including proper usage of @SpringBootApplication, component annotations (@Controller, @Service, @Repository), bean definition and scoping, configuration classes and @ConfigurationProperties, component scanning, conditional configuration and profiles, constructor injection, bean minimization, and scheduled tasks.</description>

+Apply Spring Boot Core guidelines for annotations, bean management, configuration, and dependency injection.
+
+**What is covered in this Skill?**
+
+- @SpringBootApplication and main application class
+- Component annotations: @RestController, @Service, @Repository
+- Bean definition, scoping, lifecycle
+- Configuration classes and @ConfigurationProperties
+- Component scanning and package organization
+- Conditional configuration and profiles
+- Constructor dependency injection
+- Bean minimization and composition
+- Scheduled tasks and background processing
+
+**Scope:** Apply recommendations based on the reference rules and good/bad code examples.
