   Build an agent harness and control it end-to-end. Open-source SDK for production AI agents in Python & TypeScript - any model, any cloud.

   

   Strands Agents is a lightweight Python SDK for building LLM-powered agents with tool use and session memory, open-sourced by AWS in May 2025. It is Python-native — which pairs well with the Langfuse Python SDK — and new enough to be worth exploring. Any other Python agent framework would work just as well for this PoC.
