# 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, and Mistral Vibe, with community-contributed regulatory overlays for Australia, Austria, Canada, the EU, France, the UAE, the UK, and the USA. 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, 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.
