Scaffolding works fine, for things that are common, and you already have 100x examples on the web. Once you need something more specific, it falls apart and leads to hours of prompting and debugging for something that takes 30 minutes to write from scratch.

Some basic things it fails at:

  * Upgrading the React code-base from Material-UI V4 → V5
  * Implementing a simple header navigation dropdown in HTML/CSS that looks decent and is usable (it kept having bugs with hovering, wrong sizes, padding, responsiveness, duplicated code etc.)
  * Changing anything. About half of the time, it keeps saying "I made those changes", but no changes were made (it happens with all of them, Windsurf, Copilot, etc.).
