Project history

The project frames threat modeling as a DevOps and version-control workflow: its README argues for a simple text-file format, a CLI-driven user experience, and integration with VCS. It builds on HashiCorp Configuration Language and the README explicitly connects that choice to Terraform familiarity and machine-readable structure.

Adoption history

The official documentation positions threatcl for several installation and automation paths: Homebrew, Go install, Docker, and GitHub Actions. The README also documents release provenance through SLSA and GitHub attestations, which fits the security-tooling audience that may want to verify downloaded binaries and container images.

How it is used

Users write threat models in HCL, then use the CLI to validate, list, view, export, query, generate dashboards, render data-flow diagrams, parse Terraform output, or run a server. The optional `config.hcl` file can override default classifications, impact types, STRIDE elements, and dependency classifications.

Why package nerds care

For package nerds, threatcl is notable because it turns a security documentation practice into a normal source-controlled artifact with a CLI, Homebrew install, container image, GitHub Action, release attestations, and HCL syntax familiar to infrastructure engineers.
