Unified Brain
Unified Brain is an open source perception layer providing persistent SQLite memory for coding agents to gather evidence.
Unified-brain is an open source perception layer that provides persistent memory for System One coding agents. It reads a repository git history, stores every version of every symbol in a local SQLite database using tree-sitter, and runs an embedding pass. The perception layer breaks tasks into yes-or-no calls using a decision judge model named Jev, avoiding probabilistic prose reasoning and hallucination paths. It operates through MCP on tools like Cursor, OpenCode, or Claude Code. It supports Python 3.11 or newer, OpenRouter, Voyage AI, DeepInfra, Fireworks, and Anthropic.
