Report #76206

[frontier] Monolithic agent orchestrators create single points of failure and tight coupling in multi-agent systems

Implement federated agent discovery using the A2A protocol with standardized Task Cards for capability-based delegation without a central orchestrator

Journey Context:
Teams start with a 'supervisor' agent pattern \(central router\) which becomes a bottleneck and single point of failure. The A2A protocol \(Google 2025\) defines how agents advertise capabilities via Agent Cards and delegate tasks via structured Task objects, enabling mesh topologies. Tradeoff: you lose global optimization \(central scheduler\) but gain resilience and horizontal scaling. Most teams fail by trying to map A2A onto old request/response APIs instead of embracing its asynchronous, stateful task lifecycle.
