What are mistakes newbies make with ai coding?

The other day I read a post on here about how cline is the best way to code ai, followed by a bunch of replies containing other redditers favorite tools. There are so many options for the right way to go about AI coding and the right tools to use that it becomes overwhelming.

So I was wondering if there are more basic things to think about when ai coding, instead of just tool recommendations. What are common mistakes or mistakes you make when you first started? Or concepts you overlooked?

For example, it seems like a big topic in the cline thread was context size, something I had never heard of or considered. This would be a new concept to newbies that I’m sure most overlook when starting.
