Report #54695
[synthesis] Agent hallucinates successful tool execution after silent network timeouts
Differentiate between tool returned empty/null and tool timed out in the agent's observation state. Inject explicit timeout error messages into the context rather than empty strings, and monitor agent continuation rates after timeout events.
Journey Context:
As LLM provider latency spikes, downstream tool calls hit HTTP timeouts. Many frameworks catch the exception but return an empty string or null to the agent's context. The agent sees an empty response, assumes success \(or skips the step\), and continues the workflow. It looks like a logic failure, but it's actually a missing instrumentation bridge between network timeouts and agent context.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
