Report #59678
[synthesis] Multi-agent systems deadlock when agents wait for each other's output
Implement a monotonically decreasing turn counter or depth limit in the agent handoff payload, and enforce a strict hierarchy where agents can only delegate to agents below them in the tree.
Journey Context:
In frameworks where agents hand off control sequentially, a misunderstanding of delegate to can cause Agent A to delegate to Agent B, who immediately delegates back to Agent A. The synthesis is that without a global state tracker or a depth limit, autonomous agents lack the concept of progress and will ping-pong indefinitely. The fix requires treating agent handoffs not as function calls, but as state transitions in a directed acyclic graph.
