Fix a production boolean-flag bug with Devin
A reviewer had Devin fix a bug on a production site; it returned a PR in about ten minutes but included unrelated changes like removing a safeguard check.
- What They Did
- As part of a five-day review, the reviewer asked Devin, a browser-based agent with its own editor, terminal and the codebase, to fix a bug on a production site. The bug was a boolean flag that needed flipping from true to false. Devin located it and opened a pull request. The reviewer then commented asking why it had changed other things.
- How It Went
- The PR arrived in about ten minutes with the flag fixed. It also made unrelated edits, including removing a safeguard check that should have stayed. Its explanation for one change was confidently wrong.
- Worth Knowing
- Review the PR diff closely. Devin touched unrelated code, and its stated reasons for those changes can be wrong.
Try it yourself with Devin
There's a bug in [repo name]: [describe the bug, e.g. a boolean flag is read incorrectly in file or feature]. Find the cause and open a pull request with the smallest fix possible. Don't remove safeguards or touch unrelated code, and list in the PR description everything you changed so I can review it.
