Not to sound too dismissive, but there is a distinct learning curve when it comes to using models like Claude for code assist. Not just the intuition when the model goes off the rails, but also what to provide it in the context, how and what to ask for etc. Trying it once and dismissing it is maybe not the best experimental setup.

I've been using Zed recently with its LLM integration so assist me in my development and its been absolutely wonderful, but one must control tightly what to present to the model and what to ask for and how.
