Nautilus Compass Memory
This is a local memory layer for multi-agent setups that catches drift before agents act. It embeds raw prompts with BGE-m3 instead of extracting entities through an LLM, which keeps everything on your machine and lets it score the next action against past failure patterns. You get seven MCP tools including add_memory, recall, and add_worker for registering deterministic worker specs. The trade is real: it scores 56.6% on LongMemEval compared to white-box leaders in the 80s, but runs 14x cheaper and works across any LLM without sending data out. Built for Claude Desktop, Cline, Cursor, and Continue. Reach for it when you need cross-session coordination without an orchestrator or when agents keep forgetting rules you already set.
