Version 0.1.0 documentation

A2UI A2A extension

a2ui-a2a connects the A2UI agent SDK to the Agent-to-Agent (A2A) protocol. It provides the a2ui.a2a package.

Installation

pip install a2ui-a2a

This installs a2ui-agent-sdk and a2a-sdk as dependencies.

Contents

a2ui.a2a contains:

  • Extension helpers: get_a2ui_agent_extension builds the AgentExtension that an agent advertises in its AgentCard, and try_activate_a2ui_extension activates the A2UI extension for a request when the client asks for it. get_a2ui_extension_uri and A2UI_EXTENSION_BASE_URI give the extension URI for a protocol version.
  • Part helpers: create_a2ui_part, is_a2ui_part and get_a2ui_datapart wrap and unwrap A2UI messages in A2A DataParts. parse_response_to_parts, parse_stream_chunk_to_parts, stream_response_to_parts and parse_content_to_parts turn model output into A2A parts.
from a2ui.a2a import create_a2ui_part, get_a2ui_agent_extension

extension = get_a2ui_agent_extension(version="0.9")
part = create_a2ui_part({"version": "v0.9", "deleteSurface": {"surfaceId": "main"}})

The specification of the extension is in a2ui_extension_specification.md.
