What is it?

ArcKit is a toolkit for enterprise architects that moves architecture governance out of scattered Word, Confluence and slide documents and into a structured workflow run from an AI coding assistant. It provides commands for architecture principles, stakeholder analysis, requirements, risk registers, business cases, data models, vendor RFP and evaluation, design reviews, Mermaid diagrams and requirements traceability.

It installs as a plugin or extension for Claude Code, Gemini CLI, GitHub Copilot, Codex CLI, OpenCode, Mistral Vibe and Kimi Code CLI, and can be scaffolded into a project with a Python CLI. Many commands are built around UK public sector frameworks such as the Technology Code of Practice, Secure by Design and the Green Book, with optional community overlays for EU, French, Dutch, Austrian, Canadian and UAE regulation.

All output is labelled DRAFT and is meant for qualified people to review. The project states that it does not provide legal, regulatory, clinical or security advice.

  • Public sector teams preparing procurement, business case or assurance paperwork.
  • Architects who want AI-drafted artefacts with traceable links between requirements and design.

Quick start

  1. 1

    Install the ArcKit CLI with pip

Things to know

  • The metadata lists the license as NOASSERTION, though the README badge says MIT, so check the LICENSE file before reuse.
  • Some overlay plugins, such as arckit-uk-gcloud, are proprietary and not MIT licensed.
  • Output is DRAFT material that qualified people must review; it is not legal, regulatory, or security advice.
  • Native Windows support for Codex CLI is only partial.
