Hey HN! I built RunMesh to solve a problem I kept hitting: every OpenAI project needs the same glue code for tools, streaming, memory, and multi-round loops.

RunMesh is a lightweight, typed framework that gives you: - Tool calling with Zod validation - Multi-round agent loops - Streaming with real-time events - Memory adapters - Structured output extraction

Think of it as the "React for AI agents" – explicit primitives instead of magic.

It's alpha, BSL 1.1 licensed (free for most uses, Apache 2.0 in 2027).

Would love your feedback, especially on the API design!
