Execution and Validation Flow

End-to-end flow

1. load task definition and create run directory
2. write input.md and run-progress.json (running)
3. execute by kind:
   • script: execute script body directly
   • agent: executor + user-simulator multi-round flow
4. validate result (current rule: output must be at least 1 char; agent tasks require successful chat_send delivery)
5. write output.md / result.md / run.json / dialogue.* / error.md

Result fields

• status: final status (success/failure)
• executionStatus: execution-stage status
• resultStatus: validation status (valid/invalid/not_checked)
• executionId: unique execution id
