Pattern

Google Agent Development Kit (ADK, multi-agent)

Build multi-agent systems from one agent type tree in which some agents follow fixed control flow (sequence, parallel, loop, graph), others delegate to sub-agents by LLM decision, and any agent can be exposed to or consume a remote agent over A2A.

Classification Code-first agent framework combining deterministic workflow agents, LLM-driven sub-agent delegation, and native A2A.
