How do I fix 403 Forbidden errors with this skill?

It provides a systematic approach to enable security debug logging, verify the FilterChainProxy, and correctly configure the SecurityFilterChain bean.

Does it support Spring Boot Actuator?

Absolutely. It includes a guide on essential Actuator endpoints like /beans, /env, and /mappings to inspect the application state at runtime.

How does this skill help with circular dependencies?

The skill identifies the dependency cycle chain and offers three specific strategies: using @Lazy annotations, switching to setter injection, or refactoring toward event-based communication.

Can it help diagnose database performance issues?

Yes, it provides specific configurations for SQL logging and Hibernate tracing, along with implementation patterns for EntityGraphs to solve N+1 query problems.
