[frontier] Centralized orchestrators become bottlenecks and single points of failure in multi-agent systems

Adopt a decentralized swarm topology where agents communicate via direct handoffs using lightweight protocols \(e.g., OpenAI Swarm or A2A\); each agent handles its own routing decisions based on capability matching, eliminating the central hub.

Journey Context:
Hub-and-spoke architectures \(one 'CEO' agent delegating to workers\) fail at scale because the central agent's context window overflows with worker details, and latency stacks. Production systems in 2025 are moving to 'swarm' patterns inspired by nature: agents broadcast or directly hand off tasks based on local capability advertisements. OpenAI's Swarm library demonstrates this with 'handoffs' as first-class primitives. The tradeoff is global optimality \(central planner knows all\) vs local efficiency \(no bottleneck\). For most business workflows, local matching is sufficient and more resilient. The implementation uses lightweight agent definitions with explicit handoff functions rather than a central router.
