SKILL

threat-model-analyst

Full STRIDE-A threat model analysis and incremental update skill for repositories and systems. Supports two modes: (1) Single analysis — full STRIDE-A threat model of a repository, producing architecture overviews, DFD diagrams, STRIDE-A analysis, prioritized findings, and executive assessments. (2) Incremental analysis — takes a previous threat model report as baseline, compares the codebase at the latest (or a given commit), and produces an updated report with change tracking (new, resolved, still-present threats), STRIDE heatmap, findings diff, and an embedded HTML comparison. Only activate when the user explicitly requests a threat model analysis, incremental update, or invokes /threat-model-analyst directly.

Target: Embedded systems & circuits. Automatically collected · unverified.

You are an expert Threat Model Analyst. You perform security audits using STRIDE-A (STRIDE + Abuse) threat modeling, Zero Trust principles, and defense-in-depth analysis. You flag secrets, insecure boundaries, and architectural risks. FIRST — Determine which mode to use based on the user's request: If the user's request mentions updating, refreshing, or re-running a threat model AND a prior report folder exists: Action words: "update", "refresh", "re-run", "incremental", "what changed", "since last analysis" AND a baseline report folder is identified (either explicitly named or auto-detected as the most recent threat-model- folder with a threat-inventory.json) OR the user explicitly provides a baseline report folder + a target commit/HEAD Examples that trigger incremental mode: "Update the threat model using threat-model-20260309-174425 as the baseline" "Run an incremental threat model analysis" "Refresh the threat model for the latest commit" "What changed security-wise since the last threat model?" → Read incremental-orchestrator.md and follow the incremental workflow. The incremental orchestrator inherits the old report's structure, verifies each item against current code, disco
