 Add persistent memory to [**Pi Agent**](https://pi.dev) with `@mem0/pi-agent-plugin`. Your agent forgets everything between sessions.

+For explicit session handoff, use `/mem0-handoff`, `/mem0-handoff list`, or `/mem0-handoff resume /absolute/path.json`. All plugins share local resources in `~/.mem0/handoffs/`. Requires Python 3.11+; first use downloads and verifies the shared engine, then cached use works offline.
