Install flow
- Open Domain packs from the toolbar chip (⌘⇧K) → Store tab.
- Click Install on a pack — hub downloads the release zip from GitHub and merges the embedded official catalog so new packs show up reliably.
- Toggle the pack on. You can enable multiple packs; choose which enabled pack controls IDE vs team layout in the Store tab.
- For AWS and Jira, configure credentials under Settings → Integrations after enabling those packs.
Custom and customer packs
Pack Dev Studio (Domain packs → Develop tab) lets you author pack.yaml, live-validate YAML, dev-link a folder, and test overlays before sideloading a zip. Customer packs install via Install zip or POST /api/packs/install-zip. See PACKS_CUSTOM.md.
What stays universal
Assistant, Slack Connect, collaboration, and custom experts via /create-expert work regardless of which packs you enable. Packs add depth — they do not gate the core chat experience.
