How is this proof of vibecoding?

Cursor is an “ai powered” code editor, cursorrules is a file it uses for configuration.

Unfortunately, so is Visual Studio and VS Code.

The presence of an AI assistant isn’t evidence of vibe coding. Even using that AI assistant to auto-complete lines or small sections of boilerplate isn’t vibe coding. To do that you need to ask the AI for whole swaths of code and then just accept what it gives you.

Proton’s repo here is open source. What portion of it presents issues? Any?

Sure, but cursor is different since it’s marketed as an Ai editor. VScode is just a general one.

Ai code is plausible bullshit, it may work, it may have bugs or vulnerabilities. It’s harder to spot these since its plausible bullshit.
