Google ADKFramework44/100
via “multi-agent orchestration with hierarchical agent types”
Google's agent framework — tool use, multi-agent orchestration, Google service integrations.
Unique: Implements three distinct agent execution patterns (Loop, Sequential, Parallel) as first-class types with explicit state hierarchy and context propagation, rather than generic agent composition. Each pattern has dedicated configuration classes (LoopAgentConfig, SequentialAgentConfig, ParallelAgentConfig) that enforce pattern-specific semantics and prevent misuse.
vs others: More structured than LangGraph's flexible graph approach — enforces specific execution semantics upfront, reducing debugging complexity for common multi-agent patterns at the cost of less flexibility for custom topologies
