Use A2A for agent-to-agent interoperability workflows
Expose agent capabilities and route tasks across independent agent runtimes with the Agent2Agent protocol.

pip install a2a-sdk, go get github.com/a2aproject/a2a-go, or npm install @a2a-js/sdk, then use the samples to expose and connect agent capabilities.Use A2A when the operator job is to make separate agentic applications discover one another, advertise capabilities, exchange task state, and coordinate handoffs through an open protocol. A user should invoke this instead of using an SDK normally when the task is designing or validating an agent-to-agent workflow across runtimes, not just importing a library. The boundary is interoperability design and handoff inspection across agents; it is not a generic protocol, SDK, or framework listing detached from a concrete operator workflow.
What this skill actually does
Inputs and prerequisites: A2A specification, one or more A2A SDKs, agent runtimes to expose or connect.
Setup notes: Read the A2A protocol documentation, choose the SDK that matches the target runtime, for example `pip install a2a-sdk`, `go get github.com/a2aproject/a2a-go`, or `npm install @a2a-js/sdk`, then use the samples to expose and connect agent capabilities.
Source and verification boundary: use https://a2a-protocol.org as the canonical reference before running the workflow; keep commands, API calls, CLI usage, and generated outputs reviewable against that upstream source.
Framework fit: publish this as a Multi-Framework workflow only when the operator can invoke the documented toolchain directly, rather than treating the upstream project as a generic product listing.
