1
Create a Cowork project (each team member, own machine)
Cowork UI · ~3 minutes
Name it after the Hub (e.g. "Origin Firm Hub"). Connect it to the Hub's SharePoint folder. Cowork projects can't be shared, so there is no single "shared" Hub - everyone makes their own, pointed at the same SharePoint folder.

Confirm firm.zip is installed
Auto via marketplace, or upload once
Carries the firm-hub skills (/firm-brief, /hub-session-start, /tracker-dashboard, /aggregate-tracker-snapshot, /intake-batch, /bulk-setup-matter, /conflict-sweep, /tracker-repair, /setup-profile).

/setup-firm-hub (Mode B) - run once by the Hub owner
Run inside the Hub project
Writes two files to the connected SharePoint folder root: CLAUDE.md (Hub-meta guidance) and HUB-<client>.md (client/practice reference data). Every team member's Hub project then loads them automatically via /hub-session-start - no paste, no attach. When reference data changes later, re-run it; it overwrites the files and everyone picks up the change.
