A developer tool that prevents data loss in multi-agent systems by detecting stale reads and blocking silent overwrites when agents share files, plans, or memory. It targets developers building with orchestration frameworks like LangGraph, CrewAI, or AutoGen, typically in engineering teams at companies deploying production multi-agent applications. It is an open-source Python library that implements a coherence protocol adapted from CPU cache design, offering drop-in adapters and configurable synchronization strategies.
