What are silent failures in multi-agent AI systems and why are they dangerous?
Silent failures occur when AI agents appear to be functioning normally (returning 200 OK responses) but are actually producing incorrect outputs due to logical errors, stale data, or ambiguous inputs. They're dangerous because traditional health checks monitoring for timeouts and memory leaks won't detect them, allowing bad data to flow through the system, infect other agents, and potentially become embedded as the new baseline, breaking the system from the inside.
