# The production error sweep
## Purpose
A scheduled production-log workflow that traces actionable errors to root causes, verifies fixes, opens a pull request, and stops cleanly when no action is needed.
## Prompt
```text
Review our production logs for errors. If you find an actionable issue, trace it to its root cause, fix it, verify the fix, and open a pull request. If no actionable errors are present, stop without making changes.
```
## When To Use
Use this as a scheduled reliability pass when an agent can read production telemetry, trace failures into the repository, run the relevant tests, and prepare a reviewable fix.
## Workflow
- Review the agreed production log window and group repeated symptoms into likely incidents.
- Separate actionable product errors from expected noise, transient upstream failures, and already-known issues.
- Trace each actionable error to a root cause, implement the smallest appropriate fix, and verify it with focused checks.
- Open a pull request for each verified fix. If the logs are clean, stop without making changes.
## Verifier
Actionable production errors are fixed and verified.
Finish with a pull request, or stop when no actionable errors are present.
## Notes
The loop converts passive log review into a closed reliability workflow. It requires a root cause, verified change, and review artifact instead of stopping at a list of errors.
Treat logs as sensitive production data. Do not copy credentials, tokens, personal information, or private payloads into prompts, pull requests, or chat messages.
