Tools like aider or cursor composer does not help for complex code as they destroy your mental code model of the solution you working on.

This tools help a bit for initial mocks, but even that, I don't like as they create code that I don't know and I need to review it all to know where things is.

When you are doing complex software, you need to build a good mental code model to know where things is, especialy when you need to start to debug issues, not knowing where things is is a mess and very annoying.

This days, I almost don't use this tools anymore, I just prefer basic line auto-completion.
