Repository-grounded threat modeling that enumerates trust boundaries, assets, attacker capabilities, abuse paths, and mitigations, and writes a concise Markdown threat model. Use when the user asks to threat model a codebase or path, enumerate threats or abuse paths, or perform AppSec threat modeling. Do NOT use for general architecture summaries, code review, security best practices (use security-best-practices), or non-security design work.
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 Model Source Code Repo Deliver an actionable AppSec-grade threat model that is specific to the repository or a project path, not a generic checklist. Anchor every architectural claim to evidence in the repo and keep assumptions explicit. Prioritizing realistic attacker goals and concrete impacts over generic checklists. ## Quick start 1. Collect (or infer) inputs: - Repo root path and any in-scope paths. - Intended usage, deployment model, internet exposure, and auth expectations (if known). - Any existing repository summary or architecture spec. - Use prompts in `references/prompt-template.md` to generate a repository summary. - Follow the required output contract in `references/prompt-template.md`. Use it verbatim when possible. ## Workflow ### 1) Scope and extract the system model - Identify primary components, data stores, and external integrations from the repo summary. - Identify how the system runs (server, CLI, library, worker) and its entrypoints. - Separate runtime behavior from CI/build/dev tooling and from tests/examples. - Map the in-scope locations to those components and exclude out-of-scope items explicitly. …

How to install
mdr add tech-leads-club/agent-skills/security-threat-model@sha256:f4310efb41fba14dThe line at the top of this page pins the label v1.0.0, 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.
