8.3 A Downstream Tool Task Fails

Start with the task record for the exact BioLine Tool version:

• Tool NAME:VERSION and its summary/config snapshot or hash;
• inputs and sample keys under stage;
• the task-specific saved script and actual command;
• image identity before and after pull, resource configuration, logs, and exit status.

Distinguish missing inputs, format or parameter errors, insufficient resources, incompatible Tool environment, and script logic. Preserve the error and logs first; do not silently switch versions or modify the platform Tool.

Example request: “Investigate this failed downstream Tool task. Check the exact version, summary/config, and inputs first, then inspect the generated script, actual command, resources, and logs. Explain which cause is supported by the evidence and what remains uncertain.”
