Practice Plan Mode
Practice Plan Mode on one real case. Check the result before moving on.
Step 1 of 2
Give Plan Mode one change that spans several files and answer its scope questions before accepting the plan. Check the files, tests, non-goals and verification steps, click Build, then compare the finished diff with the approved plan.
Plan Mode holds the boundary

- Okay, look at this prompt. It's not vague. It says what to change, and where it's allowed to touch: the file components/search. And it wants a plan before anything gets built. That's why Plan is on in the mode menu. Multi-file work starts right here.
- Hit send. Now watch this. It doesn't dive into edits. It researches first... then it stops at the boundary and asks about a refactor it noticed. Yes. You want that question. Not a surprise rewrite.
- And that scope question? Answer it from your own prompt. No. Stay in the file components/search.
- There it is. The build lands inside the line you drew. Three files, all under the file components/search. And the file searchFilter.ts? Untouched. That is what holding the boundary looks like.
Practice next: Now send the task in Plan Mode, answer the scope question and review the plan before you click Build.
