Snapshot of the team's shared context: your scope, who else is active, recent decisions, active locks, and any inbox messages. Call this at the start of every session.

Check whether a file or directory belongs to another dev's scope before editing it. Returns the owner and whether you can proceed.

Record an architectural decision, a non-obvious bug fix, or anything teammates should know. Append-only and shared with the team.

Search prior team decisions before making an important choice, to check if something was already resolved.

Send a message to every active teammate — breaking changes, interface changes, or coordination requests.
