threat-modeling SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
threat-modeling from ulises-jeremias/agent-toolkit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

STRIDE + agentic threat modeling — architecture discovery → assets/trust boundaries/data flows/actors → STRIDE + agentic threats → risk-ranked mitigations → incremental review → security acceptance criteria. Swarm-friendly.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Threat Modeling — STRIDE + Agentic Threats Guide **architecture → threat model → security review → security acceptance criteria**. Produces a STRIDE table augmented with agentic-specific threats (prompt injection, tool poisoning, excessive agency, inter-agent trust), risk-ranked with mitigations and acceptance criteria. **Evidence-linked, portable, incremental.** Architecture discovery reuses C4/Mermaid inputs (#369); outputs feed `agentic-security-reviewer` + `owasp-agentic-review` + `security-reviewer`. > **Sources:** Microsoft STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege) + OWASP Threat Modeling + OWASP Agentic Security (prompt injection, tool poisoning, excessive agency, data leakage, insecure plugin/MCP). See https://learn.microsoft.com/en-us/azure/security/develop/threat-modeling-tool-threats and https://owasp.org/www-project-threat-model/ . ## When to use - New system/C4 design (`architect` output), new data flow (user → agent → tool → external), new trust boundary (skill composition, MCP addition, swarm handoff) - Before `security-reviewer` / `owasp-agentic-review` prioritizes mitigations …

How to install
mdr add ulises-jeremias/agent-toolkit/threat-modeling@sha256:9c87fa52c71a8143The line at the top of this page pins the label git:20260831.856ee57, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
