The toolkit ships through two GitHub-hosted plugin marketplaces, and the observability stack updates on a third, independent path. Knowing which channel you’re on explains what “auto-update” actually updates and when you’ll see a given fix.
ArthTech-AI/arthai-marketplace is the customer channel — the one Getting Started installs:
/plugin marketplace add ArthTech-AI/arthai-marketplace
Versions here are manually promoted releases: a human decides when a version is ready for customers, so what lands on stable has already lived on the canary channel. The repo is private and license-gated — installing requires the collaborator invite you receive with your license key.
ArthTech-AI/arthai-marketplace is the faster-moving canary channel that stable releases are promoted from. Only use it if Arth AI support asks you to test a fix early — it gets changes before they’re vetted for promotion, which is exactly why support sometimes points you there (“the fix is on canary, can you confirm it works?”) and why it isn’t the default.
One canary artifact you use even on stable: the hosted Arth Intelligence update script lives at arthtech-ai.github.io/arthai-marketplace/scripts/update.sh.
Enabling auto-update (run /plugin → Marketplaces tab → select arthai → Enable auto-update) means new versions of your installed bundles — agents, skills, hooks, bug fixes — land automatically, without the manual uninstall/reinstall cycle. Three boundaries to understand:
arthai-marketplace tracks stable releases; it never silently pulls canary code..claude/knowledge/, plans, specs, the project profile — is yours and untouched. Project-local overrides in .claude/agents/ and .claude/skills/ also take precedence over plugin files of the same name and survive every update.arthai/intelligence) on its own update path: a Watchtower sidecar checks daily and recreates the container, preserving your trace data. The /otel-setup skill updates with your plugins; the engine updates via Watchtower; your local compose file only changes when you re-run the skill. Details: Getting Started 7h.Without auto-update, you update manually (/plugin marketplace update arthai, then reinstall your bundle) — the FAQ has the full flow and the reset path for stuck versions.
Release notes for the stable channel live in the arthai-marketplace repo: CHANGELOG.md. To see what version you’re currently on, run /plugin in Claude Code — installed bundles show their version.
| Channel | What | Cadence | You touch it when |
|---|---|---|---|
| arthai-marketplace (stable) | Bundles: agents, skills, hooks | Manually promoted releases | Always — this is the default install |
| arthai-marketplace (canary) | Same bundles, pre-promotion | Faster-moving | Support asks you to test a fix early |
