Error Recovery Flow Example

[!NOTE] Status: Skeleton / Planned

This example is a placeholder. Full implementation will be available in a future release.

1. Overview​

Related Golden Flow: flow-04-single-agent-llm-enrichment-single-agent-llm-enrichment

This example will demonstrate error handling and recovery patterns in MPLP:

  • Step failure detection
  • Trace span status propagation
  • Error event emission
  • Plan state rollback

2. Key Concepts​

2.1 Error States​

Steps can fail with various error types:

  • validation_error: Input validation failed
  • execution_error: Handler threw an exception
  • timeout_error: Step exceeded time limit
  • dependency_error: Required resource unavailable

2.2 Recovery Strategies​

StrategyDescription
RetryRe-execute the failed step
SkipMark as skipped, continue
AbortHalt entire plan execution
RollbackRevert to previous checkpoint

3. Placeholder Implementation​
