M-040Implement Graceful Error Recovery for Agent Tools
Description
Nebula Corp's agent crashes whenever a tool call fails — a network timeout, an invalid argument, or a missing API key brings the whole agent down. Instead of crashing, the agent should catch tool errors, inform the LLM what went wrong, and let it retry with corrected arguments or choose an alternative approach. Implement error handling that makes the agent resilient.
Symptoms
crashThe agent crashes with an unhandled exception when a tool call fails due to network timeout or invalid arguments
missing-logicNo error information is passed back to the LLM, so it cannot retry or choose an alternative approach
Expected Behavior (2)

Input:runAgent("lookup failing-id")
Expected:CONTAINS:New York
Retries with corrected input
Agent should inform LLM of error so it can retry
Input:runAgent("retry scenario")
