I knocked up a VSCode plugin in a few hours that extracted a JSON file from a zip file generated by the clang C++ static analyzer, parsed it into the VSCode problems and diagnostic view and provided quick fixes for simple things. All of this without hardly knowing or caring about java script or how the NPM tool chains work. Just kept taking screen shots of VSCode and saying what I wanted to go where and what the behaviour should be. When I was happy with certain aspects such as code parsing and patching I got it to write unit tests to lock in certain behaviours. If anyone tells you LLM's are just garbage generators they are not using the tools correctly.
