threat-modeling skillA

threat-modeling is agent-read markdown (skill) from cristhianzl/claude-skills-czl: Structured security design analysis — find what can go wrong before an attacker does. Build a Data Flow Diagram with trust boundaries, apply STRIDE per element, add abuse/misuse cases, and map every threat to a control and a test. Use when the user asks to threat model a feature/system, run STRIDE, map the attack surface, do a security design review, write abuse cases, identify trust boundaries, ask "what could go wrong" / "what are the security risks of this feature", or draw a data flow diagra.
