TeamBrain: Open-Source Tool Manages AI Coding Agent Memory via Markdown and PRs
MajorPuzzleheaded42 · reddit · 2026-07-30
TeamBrain is an open-source project designed to solve the problem of repeatedly feeding context to AI coding assistants in team environments.
- Core Mechanism: Stores agent memories as Markdown files directly inside the code repository, requiring no external database. It serves these memories to tools like Claude Code and Cursor via MCP.
- Security Design: Runs a "distiller" in CI to propose new memories as Pull Requests. All memories require human review, treating agent memory as a poisoning vector that needs strict gating.
- Retrieval & Status: Uses local hybrid retrieval (BM25 + vectors). V1 is feature-complete with 500 tests passing, but it's in early alpha with zero external users so far. The developer is actively seeking real-world feedback.
