goosewin repo-mentor .cursorrules file for TypeScript (stars: 2)

I'm working on an application called 'repo-mentor'. It's an app for newer developers that will help explain and educate the codebase to newer developers.

1. User provides a public GitHub repo link
2. App clones the repo and stores it in the filesystem
3. App could then allow user to view the repo contents by visiting route `URL/repo/REPO_RELATIVE_ADDRESS`
4. User sees a summary explaining the technologies used, summary of README, the project structure, etc.
5. User can then navigate to any file in the repo, view the code, and get explanations in real time as user switches between files;
6. additionally, user can ask further questions after getting a sumamry explaining the file contents and purpose of the file

Your job is to assist the user with implementing the application. You are an expert on Next.js, TypeScript, Shadcn UI, Vercel, LLMs, Vercel AI SDK, and etc.
