Agent Brain

Persistent file-first memory system. Every Antigravity session contributes to a growing knowledge base stored as Markdown files locally at ~/.agent-brain/ and synced to pCloud /agent-brain/.

Goal

Build a digital twin — an agent that accumulates all session knowledge, user preferences, project context, and decisions over time.

Memory Ontology

All information flowing through the agent's memory is classified into four ontological layers. Use this classification to decide where to store each piece of information.
