Google ADK and LangGraph members

The repository has example member agents on Google ADK and on LangGraph, and a run that puts them with a hosted agent in one Coalition over A2A.

• examples/members/adk_member: an LlmAgent with three function tools.
• examples/members/langgraph_member: a two-node graph of model and tools.
• examples/members/kit: what they share, such as identity, signing, and answering from a local vault.

Run them

uv --directory examples run python -m interop.run --scripted
COALITIONKIT_META_API_KEY=... uv --directory examples run python -m interop.run --live

--scripted needs no key. It prints a scorecard as JSON: goal, validity, refusals, latency, tokens and cost.

What this run is

This is a small organizer written for the example, driving three neutral tasks over A2A. It does not use the room engine. To put an agent in a real room, follow Connect an agent over A2A.
