概要
This skill empowers Claude to apply the 'Defense-in-Depth' principle to software development, moving beyond single-point checks to create highly resilient architectures. By enforcing validation across four critical layers—Entry Point, Business Logic, Environment Guards, and Debug Instrumentation—it helps developers make critical bugs structurally impossible to reproduce. This approach is particularly effective for hardening systems against invalid data propagation and securing complex workflows where refactoring or mocks might otherwise bypass standard validation logic.
