There is a folder for a VS Code extension here[0]. It seems to have a README with installation instructions. There is also an extension.ts file, which seems to me to be at least the initial prototype for the extension. Did you forget that you started implementing this?

From a fellow LLM-powered app builder, I wish you best of luck!

Yes, there is a VS Code folder in that repo. However, it doesn't exist as an actual extension. It's an experiment that does not remotely work.
The LLM generated docs has confidently decided that not only does it exist, but it is the primary installation method.
This is wrong.
Edit: I've now had to go into the Readme of this extension to add a note to LLMs explicitly to not recommend it to users. I hate this.
This is not an ad for LLMs. If you think this is good, you should probably not ever touch code that humans interact with.
