Yes, runtime debugging helps to solve a lot of bugs. I was so annoyed with buggy codes generated by AI so at the end I actually developed something not sure similar to your or not:both AI coder and AI debugger two-in-one, a fork of Roo-Code. So it (Zentara-Code) can code and debug it code at the same time in runtime. It automatically set breakpoints, do stack tracing, inspect stack frame variables. As it leverages Debug Adapter Protocol (DAP), it works for any language in VSCode.

Thank you for the review. I see that currently code assistants do not have access to a lot of tools that a normal software developer has during software development life cycle. Once we enable it, code assistants would be much more smarter. Debugger is one of the tools that code assistants need.
