Reference

Every a2a CLI command and one page per documented a2a_pack module, auto-generated from the SDK source at this monorepo revision, plus hand-written references for the project manifest and the control-plane API.

This is not an index of every symbol a2a_pack exports. Roughly half of the public exports live in the modules below; the rest — the Agent DSL, receipts, replay, memory, consumer setup, mail, and the meta-agent engine — are not in the generated reference yet. Use the concept pages or the source for those.

Project manifest

• a2a.yaml — the manifest every deploy reads: identity, entrypoint, expose.public, packed frontend, runtime, and platform resources.

• a2a_pack.workspace — WorkspaceClient, install_grant.
• a2a_pack.runtime — runtime that hosts the agent.
