Use A2A for agent-to-agent interoperability workflows
Expose agent capabilities and route tasks across independent agent runtimes with the Agent2Agent protocol.
npx skills add agentskillexchange/skills --skill use-a2a-for-agent-to-agent-interoperability-workflows
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.
