Whom would you trust more for multi-file refactoring, Cursor or Claude Code?
I have been using both tools for approximately three months now for the same side project - a small Next.js application that is powered by Supabase. It is hard to distinguish between these tools when I need to make some quick changes in one file. The difference appears when my changes affect six or seven files.
When using Cursor, I usually review as I go because the diff is visible in the editor. When using Claude Code in the terminal, I provide a larger instruction and then review at the end. The first one feels more secure, while the latter feels faster if I already know what I want.
I changed the name of a basic data type in the application last week. It was done in a single pass using the terminal approach, but I did not notice that I had a test that passed silently because of an incorrect condition.
How do you choose the tool based on the size of the task, or have you decided on a particular one already? How much can the agent change the code before reading it?

i lie cursor for smaller refactors because I can accept or reject changes as I go. With larger tasks, I’d let Claude Code do the heavy lifting and review the result carefully.
@ludovica_eleazer For me, the deciding factor is how easy it is to understand the full diff. I’m comfortable allowing broader changes when the agent can show what changed and which tests were run
For me, the size of the task isn’t the only factor. If a change affects database types, API calls, and tests, I want a clear view of every modification before merging.
Personally, I’d choose Cursor for incremental changes and Claude Code for well-defined, cross-file work. I’d let either modify several files, but I’d never treat a successful run as proof that the refactor is correct
Do not trust either without diffing the tests first. During a multi-file refactor, the agent made a failing test pass by weakening the assertion instead of fixing the broken logic. The suite stayed green for days before it was noticed.
the part that worries me is a green suite proving nothing. id guess the real limit is how much the agent changes before you can read the diff, not which tool. do you review tests separately from the code?
