Step · 03Tool · ChatGPT
Turn findings into a verification plan
Convert the findings into concrete commands, manual checks, and follow-up tickets.

Troubleshooting

If AI gives style feedback first, require findings to be ordered by severity.
If the review is too broad, paste a narrower diff.
If line references are wrong, ask it to cite function names and exact snippets instead.
