Multi-Agent Failure Cases
Multi-agent systems have unique failure modes. Understanding these helps build more resilient systems.

Common Multi-Agent Failures
- Agent deadlock: two agents each waiting for the other to complete — avoid by never having circular dependencies
- Cascading failure: one agent fails and its error propagates through the entire pipeline — isolate failures at each step
- Conflicting results: two agents produce contradictory outputs — use a reviewer agent to reconcile conflicts
- State corruption: two agents write to the same state key simultaneously — enforce namespace isolation
- Lost message: a task assignment is never received — use message acknowledgement and timeouts
- Infinite revision loop: reviewer always rejects, writer always fails to fix the issue — enforce a maximum revision count
