majiayu000 CVM Troubleshooter
Collect diagnostics first, then propose the smallest rerun.
Workflow
- Collect diagnostics using the bundled script.
bash skills/cvm-troubleshooter/scripts/collect_diagnostics.sh
- Classify failure by stage.
- Ingestion failures: raw data path, missing
raw_*.csv, mapping errors. - Prepare-data failures: dbt binary/path, dbt test failures, mart contracts.
- Train failures: missing target columns, empty training marts, model backend deps.
- Score failures: missing decision queue, missing signal tables, reason quality gate.
- Propose exact fix + rerun command.
- Do not propose broad changes. Give one minimal change and rerun only affected stage.
- Return a concise incident report.
- include root cause, fix, and verification output path.
