Defense-in-Depth Validation

The Defense-in-Depth skill provides a rigorous framework for securing critical data paths by establishing validation checkpoints at every layer of execution. Instead of relying on a single point of failure, this skill guides the implementation of four distinct layers: entry-point validation, business logic rules, environment guards, and debug instrumentation. It is ideal for complex systems where invalid data could bypass simple checks through mocks or refactoring, ensuring that systems remain resilient and easy to debug even when edge cases occur.
