Threat Modeler

This tool analyzes a provided system architecture description to identify trust boundaries, STRIDE threats, and structural security flaws, producing a rigorous JSON threat model. It accepts a required architecture_description string describing system components, data stores, external dependencies, trust boundaries, and data flows, plus an optional constraints string containing a comma-separated list or paragraph of known constraints, invariants, assumptions, or security requirements. The output must strictly validate against the system-provided structured output schema that is auto-produced and referenced externally, and the model must not introduce fields that are not defined in that schema.
