defense-in-depth

This skill teaches a four-layer validation pattern for catching invalid data at multiple system boundaries. It provides concrete TypeScript examples for entry validation, business logic checks, environment guards, and debug instrumentation. The approach makes certain bugs structurally impossible by validating at every data flow layer.
