Langroid

Langroid is a Python multi-agent framework built around message routing between agents, with tools, vector-store access, task delegation, and human participation hooks. Agents collaborate by exchanging typed messages rather than only sharing a free-form chat transcript. Use it as a reference for role-to-role messaging patterns inside an OS (estimator ↔ scheduler ↔ approver). Operators evaluating Langroid should check embedding/index APIs, persistence and filter semantics, and how retrieval latency shows up under the load that matters for their corridor—not only demo latency.
