Example

One change, then run

A short operator prompt for any stack. Stops the model from rewriting the whole app to fix one line.

Claude Code

Do the next change only.

1. Name the one thing that is wrong, in one sentence.
2. Name the one file you will edit.
3. Edit that file. Do not tidy neighbours.
4. Run the smallest check that proves the change.
5. Stop and report: what you changed, what you ran, what is still open.

    If you cannot do it in one file, say so and wait.
