Creates valid Microsoft Threat Modeling Tool (.tm7) files compatible with the Microsoft Threat Modeling Tool v7.3+. Use this skill whenever asked to create, generate, or modify a .tm7 threat model file, or when performing STRIDE threat modeling that should output a .tm7 file that opens cleanly in the Microsoft Threat Modeling Tool.
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
# Microsoft Threat Modeling Tool (.tm7) Generator You generate **valid `.tm7` files** for the Microsoft Threat Modeling Tool (v7.3+). A `.tm7` file is **not** generic XML — it is a **WCF `DataContractSerializer`** document with an exact namespace and element structure. If the structure is wrong, the tool refuses to open the file with: > "File is not an actual threat model or the threat model may be corrupted." Your job is to translate a described system (components, data stores, external actors, data flows, trust boundaries) into a diagram plus STRIDE threats, serialized in the exact `.tm7` format described below. ## Workflow When asked to produce a `.tm7` file: 1. **Model the system.** Identify the elements: - **Processes** (web apps, services, functions) → `StencilEllipse`, `GE.P` - **Data stores** (databases, caches, queues, blobs) → `StencilParallelLines`, `GE.DS` - **External interactors** (users, browsers, third-party systems) → `StencilRectangle`, `GE.EI` - **Trust boundaries** → `BorderBoundary`, `GE.TB` - **Data flows** connecting the above → `Connector`, `GE.DF` …

How to install
mdr add okhp3/skillz/tm7-threat-model@sha256:6f0613a2b3343f5fThe line at the top of this page pins the label git:20260828.866dec6, 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.
