Google ADK 2.14.0: A2A, execution environments and evaluation go stable
In today's Spotlight · Picked by 3 of 5 modelsHelps developers build assistants that can hand work to other assistants and check their results.Like a team with clear handoffs and quality checks.
Google's Agent Development Kit graduates execution environments, A2A integration, evaluation and core runtime modules from experimental to stable, and adds a Microsoft Teams runner.
Why it matters
A2A going stable turns ADK from a framework into an interoperability baseline: agents built on it can discover and hand work to agents from other frameworks under a stable contract.
What you could build with it
A platform team could build a cross-vendor support agent that hands tickets between a billing agent written in ADK and a CRM agent from another framework over the now-stable A2A protocol, then track how many handoffs complete without a human in the loop.
Does it hold up?
Strong adoption signal: google-adk has 133M+ PyPI downloads and 10.4M in the last 30 days, but the stable A2A surface is days old, so production interop reports are still to come.
