Enforce certain vite-plus imports via lint rules instead of Markdown files

[connorshea]

Description

I noticed that the generated AGENTS.md/CLAUDE.md file includes this line:

- **Import JavaScript modules from `vite-plus`:** Instead of importing from `vite` or `vitest`, all modules should be imported from the project's `vite-plus` dependency. For example, `import { defineConfig } from 'vite-plus';` or `import { expect, test, vi } from 'vite-plus/test';`. You must not install `vitest` to import test utilities.

This is fine, but it would be better to enforce this properly - even better if it can get auto-fixed.

Suggested solution

We could add an oxc/vite-plus-imports lint rule in Oxlint to enforce and auto-fix these imports, potentially. And have it enabled by default as part of generating the vp config and/or running migrate.

It could alternatively be provided as a JS Plugin rule by vite-plus, if we don't want to ship it in Oxlint directly.

Alternative

Continue to rely on the AI agents to respect this and probably get it wrong sometimes/a lot of the time, especially while models haven't been trained on vite-plus yet.

Additional context

Right now this feels like an unnecessarily-painful papercut, because AI agents will continue to just use vitest or vite imports until, hopefully, they're re-trained on updated info, and a new gen of models is released in 6ish months. And human developers won't necessary know that this is a problem either until they run into issues because of it.

Validations

• Read the Contributing Guidelines.
• Confirm this request is for Vite+ itself and not for Vite, Vitest, tsdown, Rolldown, or Oxc.
• Check that there isn't already an issue requesting the same feature.

look good cc @TheAlexLichter

Great idea, especially with an autofix. Then we could move the rewrites from Vite+ into Oxlint, too.

Yes, please! A lint rule would be ideal for that 👏🏻

If you aren't currently working on it, would it be okay if I did?
