debugging-and-git-checkpoints

To isolate a bug with git checkpoints, reproduce the issue, create a checkpoint commit, apply a minimal focused fix, re-test, and verify the git diff before committing. This preserves a clean history and enables easy rollbacks.

The best way to debug with minimal focused edits is to reproduce the bug, create a git checkpoint, fix only the single most likely cause, and review the diff before committing. This approach captures a stable baseline and enables safe rollbacks if the fix fails.

Using git checkpoints before risky edits in Codex-assisted development involves creating a stable baseline commit before applying changes. You then fix the bug, re-test, and verify the explicit git diff to ensure the Codex iteration is reviewable and reversible.

You should verify a git diff before committing a bug fix to enforce minimal-change discipline and ensure reproducibility. Reviewing the diff confirms that only the intended focused edit was applied, preventing unintended side effects from entering the clean git history.

Yes, you can use this debugging workflow for classroom coding assignments. It specifically supports classroom debugging by guiding students through bug reproduction, checkpoint creation, single-cause fixes, and diff verification to maintain a clear, reviewable git history.

If your bug fix breaks something else after a git checkpoint, you should roll back to the stable baseline captured before the risky edit. The checkpointed git history allows you to safely revert the failed minimal fix and re-attempt the debugging iteration.
