What is ArcKit?
117 AI-assisted commands that generate complete governance documents — from stakeholder analysis and risk registers to design reviews and traceability matrices. Each command produces template-driven, audit-ready artifacts. The UK Government baseline (71 core commands) ships alongside community-contributed overlays for the EU, France, Austria, Canada, and UAE.
Systematic
Follow GDS Agile Delivery phases with a structured command workflow. Every artifact is version-controlled, traceable, and linked to business drivers.
Multi-Jurisdiction
UK Government core (TCoP, Secure by Design, GDS Service Standard, MOD JSP 936, HM Treasury Green/Orange Books) with community overlays for GDPR, AI Act, NIS2, ANSSI, PDPL, and more.
AI-Assisted
Works with Claude Code, Gemini CLI, Codex CLI, OpenCode CLI, and GitHub Copilot. AI generates first drafts from templates; architects review and refine.
How it works
ArcKit follows the UK Government's GDS Agile Delivery framework, with commands mapped to each phase:
Planning
Planning
Define architecture principles and create your project structure.
Discovery
Identify stakeholders, assess risks, and build the strategic outline business case.
Alpha
Gather requirements, model data, research technology options, and map strategy.
Beta
Procure services, evaluate vendors, review designs, and generate the delivery backlog.
Live
Verify traceability, ensure operational readiness, and tell the project story.
Jurisdictions covered
ArcKit ships a UK Government baseline alongside five community-contributed jurisdictional overlays. Use the command reference to filter by jurisdiction or tier — every overlay command is badged [COMMUNITY] and excluded from the official-tier count.
GDS Service Standard, Technology Code of Practice, Secure by Design, MOD JSP 936, HM Treasury Green & Orange Books, G-Cloud and DOS procurement, AI Playbook, ATRS.
Jurisdiction-agnostic foundations: requirements, ADRs, Wardley Mapping, DevOps / MLOps / FinOps, traceability, conformance, vendor evaluation.
GDPR, EU AI Act, NIS2, DORA, Cyber Resilience Act, Digital Services Act, Data Act.
ANSSI Guide d'hygiène, SecNumCloud 3.2, EBIOS Risk Manager, DINUM (RGI / RGAA / RGS / RGESN), CNIL RGPD, Diffusion Restreinte, code de la commande publique.
NISG (NIS2 transposition), DSG / DSGVO, Bundesvergabegesetz 2018 procurement.
FITAA (C-70), PIA, ATIP, Algorithmic Impact Assessment, Charter, SOIA, GC Digital Standards, cloud residency, Official Languages Act, OCAP, PSPC procurement.
PDPL, IAS controls, sovereign cloud residency, UAE Pass integration, Smart Data classification, AI Charter, autonomy tier, federal procurement, digital records.
Government Code Discovery
Search 24,500+ UK government repositories before building from scratch. Powered by govreposcrape, no API key required.
gov-code-search
Natural language search across government repositories. Find how other departments solved similar problems.
gov-reuse
Systematic reusability assessment. Score candidates on licence, quality, documentation, tech stack, and maintenance.
gov-landscape
Map the government code landscape for a domain. Identify who built what, common patterns, and collaboration opportunities.
Supports TCoP Point 3 ("Be open and use open source") and the CDDO "reuse before build" principle. Existing research commands now include a government reuse check as a fifth build-vs-buy option.
