/mailbox — Persistent Agent Memory

Agents die. Knowledge survives. ψ/ remembers what ~/.claude/ forgets.

Team agents in Claude Code use ephemeral file-based mailboxes that die with the session. /mailbox adds a persistent layer in ψ/memory/mailbox/ — agents remember across sessions.

Usage

/mailbox                                    # List all agent mailboxes
/mailbox read <agent>                       # Read agent's mailbox
/mailbox read-all                           # Read all mailboxes
/mailbox write <agent> "<subject>" "<msg>"  # Write finding to agent
/mailbox orders <agent> "<instructions>"    # Set standing orders
/mailbox load <agent>                       # Pre-load context for spawn prompt
/mailbox archive <agent> <team>             # Archive session end
/mailbox clear <agent>                      # Clear mailbox (→ /tmp, not deleted)
