I let Cursor clean a function I was ashamed of

I treat every claim as load-bearing until the source proves it.

It rewrites more than you ask. The skill is reviewing the diff like a senior you don't fully trust.

Select the function and ask for one change, not 'improve.' 'extract the validation' beats 'make it clean.'

Read the diff before you accept; it once deleted a guard clause I needed.

Commit after each small fix so a bad rewrite is one undo, not a panic.

The catch the result was a thing I actually use, not a screenshot I forget.
