The Enterprise Architecture Governance Harness — a Claude Code plugin providing 75 slash commands across strategy, architecture, delivery, assurance, and interoperability.
ArcKit needs Claude Code v2.1.200 or later (see Prerequisites below). The simplest way to land on a supported version — even if you've never installed Claude Code before — is:
claude install latest
If you don't yet have the claude CLI on your PATH, follow the official Claude Code install guide first, then run claude install latest. To check what you're on:
claude --version
In Claude Code, run:
/plugin marketplace add tractorjuice/arckit-claude
/plugin
Go to the Discover tab, find arckit, and install it. Or via CLI:
claude plugin install arckit@arckit-claude
The same marketplace hosts the core plugin plus regional, sector, and tooling overlays. Install only the plugins you need:
claude plugin install arckit arckit-uae
claude plugin install arckit arckit-au arckit-au-energy
claude plugin install arckit arckit-uk-finance
The arckit-uk-gcloud overlay is public for installation and inspection, but remains
proprietary and is not MIT licensed.

claude agents --plugin-dir <dir>visibility for plugin agents/skills, which makes ArcKit branch and test-repo workflows reliable. It also carries the v2.1.198-v2.1.199 background-subagent reliability, parent error-propagation, and hook stderr-visibility fixes that matter to/arckit:build, reader/writer handoffs, and hook diagnosis. v2.1.197 makes Claude Sonnet 5 the default Claude Code model with native 1M context, while v2.1.172 fixed wildcard-domainWebFetchpermission rules (WebFetch(domain:*.gov.uk)) that never matched subdomains on earlier clients. The floor also carries forward the older MCPalwaysLoad, provenance hook, release validation, telemetry,/context, Auto mode, plugin update, MCP leak, retry, and subagent working-directory fixes ArcKit relies on.
