System Documentation

What problem does it solve?

Turns a codebase into a clear, reviewable Data Flow Diagram (DFD) with explicit trust boundaries and data classifications so security and compliance work can start from one reliable source of truth.

Core Features & Use Cases

  • Canonical DFD production: Extracts external actors, processes, data stores, data flows, trust boundaries, and per-element data classifications from code using a six-axis discovery pass.
  • STRIDE-ready outputs: Produces Mermaid DFD documentation and (optionally) Threat Dragon v2 JSON so downstream threat modelling and GDPR/compliance checks can consume the same diagram.
  • Human-in-the-loop correctness: Presents a candidate model for operator review and supports overwrite prompts with drift-aware re-run behavior.

Quick Start

Ask for a system-wide DFD draft by running: /dfd billing-api --scope-all
