# ArcKit

> ArcKit is The Enterprise Architecture Governance Harness — an open-source toolkit covering strategy, architecture, delivery, and assurance — that provides AI-assisted slash commands for Claude Code, Gemini CLI, GitHub Copilot, Codex CLI, OpenCode CLI, Mistral Vibe, Paperclip, and Kimi Code CLI, with community-contributed regulatory overlays for Australia, Austria, Canada, the EU, France, the UAE, the UK, and the USA, plus sector overlays for UK financial services payments, UK NHS clinical safety, the Australian energy sector, and UK G-Cloud suppliers, and method overlays for TOGAF ADM and AI agent architecture. It transforms architecture governance from scattered documents into a systematic, template-driven workflow covering requirements, stakeholders, risk, business cases, architecture (C4, Wardley, ADRs), research, vendor procurement (G-Cloud/DOS), UK Government compliance (GDS, TCoP, Secure by Design, NCSC CAF, Orange/Green Book), EU regulations (GDPR, NIS2, AI Act, DORA, CRA, DSA, Data Act), French government compliance (SecNumCloud, ANSSI, EBIOS, CNIL, DINUM, PSSI), Austrian compliance (DSG/DSGVO, NISG, BVergG), Canada Federal compliance (FITAA, Privacy Act PIA, ATIP, Algorithmic Impact Assessment, Charter rights, ITSG-33, SOIA, sovereign cloud residency, GC Digital Standards, Official Languages Act, PSPC procurement, OCAP®), UAE Federal compliance (PDPL, IAS, AI Charter, sovereign cloud, UAE Pass), USA federal civilian compliance (FedRAMP, FISMA / NIST SP 800-53, CISA Zero Trust Maturity Model, OMB M-19-17 ICAM, NIST AI RMF, OMB M-24-10 / M-25-21, E-Gov §208 PIA, EO 14028 secure software self-attestation), DevOps/MLOps/FinOps, and traceability. /arckit:build is a Claude Code-only parallel build harness that orchestrates end-to-end artefact generation against a YAML recipe (uk-saas, uk-mod-sovereign, uae-federal-ai, ca-federal-fitaa, us-federal, and others).

ArcKit is distributed as a Claude Code plugin, a Gemini CLI extension, a GitHub Copilot prompt pack, a Codex CLI extension, an OpenCode CLI extension, a Mistral Vibe extension, a Paperclip extension, a Kimi Code CLI extension, and a Python CLI (`arckit init`). Source code and issue tracker: https://github.com/tractorjuice/arc-kit.

Every command reads a template from `.arckit/templates/`, creates or reuses a numbered project directory (`projects/NNN-name/`), writes a versioned artifact (`ARC-NNN-<TYPE>-vX.Y.md`) using the Write tool to avoid token limits, and maintains traceability: Stakeholders → Goals → Requirements (BR/FR/NFR/INT/DR) → Data Model → Components → User Stories.
