ArcKit: The Enterprise Architecture Governance Harness

Build better enterprise architecture through structured strategy, design, delivery, and assurance workflows.

ArcKit is a toolkit for enterprise architects that transforms architecture governance from scattered documents into a systematic, AI-assisted workflow for:

• 🏛️ Establishing and enforcing architecture principles
• 👥 Analyzing stakeholder drivers, goals, and outcomes
• 🛡️ Risk management (HM Treasury Orange Book)
• 💼 Business case justification (HM Treasury Green Book SOBC)
• 📋 Creating comprehensive requirements documents
• 🗄️ Data modeling with ERD, GDPR compliance, and data governance
• 🔬 Technology research with build vs buy analysis (web search powered)
• ☁️ Azure-specific research using Microsoft Learn MCP for authoritative documentation
• 🗺️ Strategic planning with Wardley Mapping
• 📊 Generating visual architecture diagrams (Mermaid)
• 🤝 Managing vendor RFP and selection processes
• ✅ Conducting formal design reviews (HLD/DLD)
• 🔧 ServiceNow service management design
• 🔗 Maintaining requirements traceability
• 📎 Citation traceability for external documents (inline [DOC-CN] markers with source quotes)

Star History

Quick Start

Installation

Claude Code (premier experience) — install the ArcKit plugin (requires v2.1.200+):

First, make sure Claude Code is on the latest version:

claude install latest

Then in Claude Code:

/plugin marketplace add tractorjuice/arckit-claude

Then install from the Discover tab, or via CLI. The marketplace ships 15 plugins — install only the overlays you need:

# Core (75 commands — UK Government civilian + generic enterprise)
claude plugin install arckit@arckit-claude

# Core + UAE federal
claude plugin install arckit arckit-uae

# Broad overlay set (UK + UAE + FR + CA + EU + AT + AU + US + UK-NHS + UK-GCloud)
claude plugin install arckit arckit-{uae,fr,ca,eu,at,au,us,uk-nhs,uk-gcloud}

# Enterprise architecture and AI agent governance overlays
claude plugin install arckit arckit-togaf-adm arckit-agent-architecture

The standalone tractorjuice/arckit-claude marketplace hosts all Claude Code plugins: the arckit core plugin, regional overlays, sector overlays, the TOGAF ADM and AI agent architecture overlays, the arckit-fde tooling plugin, and the public-but-proprietary arckit-uk-gcloud supplier overlay. The 13 community plugins (arckit-uae, arckit-fr, arckit-ca, arckit-eu, arckit-at, arckit-au, arckit-au-energy, arckit-us, arckit-uk-finance, arckit-uk-nhs, arckit-uk-gcloud, arckit-togaf-adm, arckit-agent-architecture) require the arckit core plugin. arckit-au-energy (sector) additionally requires arckit-au (jurisdiction), which it composes — install with claude plugin install arckit arckit-au arckit-au-energy. arckit-uk-gcloud is a proprietary, Claude Code only supplier-side G-Cloud bid-authoring overlay — it is public for installation and inspection, but not MIT licensed and not distributed to the non-Claude extension formats. One tooling plugin — arckit-fde — is a lean, Claude Code only plugin with one command, /arckit-fde:create, that generates a brandable (white-label) Forward Deploy Engineering consulting website into docs/ (GitHub Pages ready), with UK Public Sector and Generic market presets; no dependencies, not converted to non-Claude formats, no governance doc-types.
