Make One Small Change and Review the Diff1 / 2

2 min lesson

The job: one small edit lands with a diff you understand and can undo

Use "One small edit lands with a diff you understand and can undo" to describe the practical rule.

Step 1 of 2

The job: one small edit lands with a diff you understand and can undo. Start with this check: Only expected files changed. Keep it small enough to check the result yourself instead of taking the summary on trust.

One small change, read every hunk

  1. Open the file with the label. Select just line 12. That selection is the blast radius. Cursor should only touch what you highlighted.
  2. One line? Use Inline Edit. Command-K. Not Agent. Type the exact reword, then wait for the hunk.
  3. Read every line of that hunk before you Accept. Then check Source Control. One modified file. That is your receipt.
Watch once: select → → read the hunk → Accept → verify in Source Control.

Practice next: Now run the walkthrough: make the one-line Inline Edit, read the hunk, and verify the single-file diff.
