# Resilience and Error Handling

> Build reliable agents using retries, post-hook error management, and explicit stop conditions.

Use automated retries for transient API issues and stop conditions for unrecoverable errors to prevent execution loops.

| Example                                                                                     | Description                                                                                             |

| [Retry Tool Call](/examples/tools/exceptions/retry-tool-call)                               | Implement automatic retries for flaky or rate-limited tool executions.                                  |
| [Retry Tool Call From Post Hook](/examples/tools/exceptions/retry-tool-call-from-post-hook) | Intercept errors and trigger retries using post-execution hooks to maintain workflow continuity.        |
| [Stop Agent Exception](/examples/tools/exceptions/stop-agent-exception)                     | Gracefully terminate execution when specific error conditions are met to prevent "hallucination loops." |
