The LaTeX Prompts That Actually Change the Document

The single property that decides whether an AI assistant edits your LaTeX or lectures you about it is whether your sentence is a question or an instruction. "How do I make this two columns?" has a correct answer in chat, so you get one. "Make this two columns" names an action on a file, so the file changes. Everything else, the politeness, the length, the word "please", makes almost no difference.

That is not a quirk of one product. It is what the words mean. Below are the asks that produce an edit, what each one triggers, and what the vaguer version gets you instead.

Prompts that produce a diff

+ \usepackage{booktabs}
+ \begin{table}[h]
+   \begin{tabular}{lrr}
+     \toprule
+     Model & Accuracy & F1 \\

Three habits that do more than any wording

Name the boundary, not just the goal. Almost every bad outcome from an AI edit is something changing that you did not ask about. "Keep the section order", "do not touch the preamble", "leave the figures alone" cost you five words and remove most of that risk.

Let it read the file rather than pasting one. A pasted copy is stale the moment you keep typing, and the answer comes back as text you have to merge by hand. An assistant that can open the project reads what is there now and proposes a diff you accept or reject.

Make it compile before you believe it. LaTeX that looks right is not the same as LaTeX that builds, and the gap is usually a package that was never loaded. An assistant that ends its work with a real compile has checked something; one that ends with a confident paragraph has not.

What to do when it goes wrong anyway

Reject the diff and say what was wrong with it, in the same words you would use with a colleague: "that changed the figure numbering, put it back". The correction is cheap because the edit was proposed rather than applied. If you are working on something you cannot afford to have touched, keep the changes pending and read them before accepting, which is what the review step is for.
