Produce a threat-model artifact for an agentic system or any risk-surface change. Walks the author from risk signal (new tool / MCP / LLM call / persistent memory / auth boundary / external API / user-data handling) to a finished markdown threat model with assets, actors, data-flow description, STRIDE decomposition, OWASP LLM/Agentic cross-map, mitigations, residual risk, and a decision log. Output satisfies build-loop's plan-verify rule 10 (`risk-surface-change-without-threat-model`). Activates when the user asks for a threat model, a security review of a design, OWASP/ASI mapping for a feature, or a "is this risk-surface change covered" check; also activates implicitly when a plan introduces any risk-surface signal without an existing threat-model artifact.
