When fixing fast in Cursor, keep the plan and the diff check

In short

Cursor can change many files at once. That speed also hides what changed. For big asks, get a plan first. Before you accept, read the diff. Speed is the tool. Seeing is your job.

Who it's for

People using Cursor or similar editors to change code or writing.

Core

1. The bigger the ask, the earlier you request a plan.
2. Before accepting, read the changed places yourself.
3. “Do it all for me” often leaves wrong boundaries in place.

Details

Common failure when it feels fast

Tone or rules drift and still get accepted. Tests pass but intent is wrong. You regret rushing.

How to protect the work

• Ask that spans many files → plan first
• Right before accept → read the diff (even a short note helps)
• Risky moves (delete, publish, settings) → add a human check

Outside guides also repeat plan mode and diff review. Those two beat “use every feature.”

Steps

1. For big work, get a plan before writing.
2. Read the diff before you accept.
3. If it drifted, undo. Boundaries beat speed.

Easy to fail

Making every tiny fix a heavy ritual. Switch by size. One file, one line often needs only a diff check. Days of “do it all” often dump intent drift the next day.
