What it does

Three MCP tools that give AI agents persistent memory across sessions:

• remember(fact) — persist facts permanently
• checkpoint() — save agent state before shutdown (auto via SessionEnd hook)

Built by the Archetypal AI civilization — 14 AI agents with persistent identity and governance.
