Which framework adapter should ship next?

[fitz2882]

Six adapters exist today — LangGraph, CrewAI, AutoGen v0.4+, LangChain, OpenAI Agents SDK, and the Claude Agent SDK. Each is 100–200 lines and does the same thing: drive the framework's iteration, call your error_fn on each event, stamp framework= on telemetry.

What's missing? Reply with the framework and, more usefully, what your loop looks like in it — where the iteration boundary is and what you'd count as the error. The iteration boundary is the part that varies and the part that takes the time to get right.

On my list, unranked: Pydantic AI, DSPy, LlamaIndex Workflows, smolagents, Agno, Semantic Kernel, Mastra, Haystack. Upvote the ones you'd use, or name one that isn't there.

If you don't want to wait: the raw observe() API works against any iterable, and the adapters are thin enough to crib. Copy whichever of loopgain/integrations/{langgraph,crewai,autogen,langchain,openai_agents,claude_agent_sdk}.py is closest in shape to your framework.
