Report #44349

[frontier] Multi-agent systems require hardcoded orchestration graphs that break when adding new agents or changing capabilities

Use Agent-to-Agent \(A2A\) protocol for dynamic capability discovery: agents advertise skills via Agent Cards, delegate tasks via standard Artifacts, and negotiate without central orchestrator

Journey Context:
Current multi-agent frameworks \(CrewAI, AutoGen\) use static DAGs or hierarchical trees defined in code. Adding a new agent requires rewriting the orchestration logic. Google's A2A protocol \(2025\) treats agents as autonomous services in a mesh. Each agent publishes an Agent Card \(JSON metadata\) advertising capabilities, endpoint URLs, and authentication. Task delegation uses standard message types \(Task, Artifact, Part\) over HTTP/SSE. This enables truly dynamic swarms where agents discover peers at runtime, form ad-hoc coalitions for complex tasks, and gracefully handle agent failures without central points of failure.
