+# [Team Name] — Team Brain
+
+> Last updated: [DATE]
+> Scope: shared team context (not personal). Personal growth stays in each engineer's BRAIN.md.
+
+---
+
+## Identity
+
+- **Team:** [Team name]
+- **Org / product:** [Product or org]
+- **Mission:** [1–2 sentences]
+- **Primary repos:** [repo1, repo2, …]
+- **Standup channel:** [Slack/Teams thread]
+
+---
+
+## Norms
+
+- [How you review PRs]
+- [How you break down epics]
+- [Definition of done / quality bar]
+- [How AI context is shared — what is OK to `remember` into initiative memory]
+
+---
+
+## Members (opt-in)
+
+| Name | Role | Primary focus | Share scope |
+|------|------|---------------|-------------|
+| [Name] | [Role] | [Focus] | research / metrics / none |
+
+---
+
+## Active Initiatives
+
+| ID | Title | Status | Owners | Initiative file |
+|----|-------|--------|--------|-----------------|
+| [TICKET-1] | [Title] | active | [names] | `initiatives/TICKET-1.md` |
+
+---
+
+## Sync notes
+
+- **Preferred:** `sync.backend: supabase` — register/join once; captures sync for the whole team; each initiative mirrors to `initiatives/<JIRA-KEY>.md`
+- **Fallback:** `local` — share `.team-brain/` via git commit/PR/pull
+- Jira keys identify initiatives; do not dump personal `BRAIN.md` into team files
+
+Use `/team-brain register` then `/team-brain attach <JIRA-KEY>`.
