I am a new to vibe codeing, I am running into the tool having major limitations of larger code lengths. In my .cursorules, what should be the optimal rule set to prevent the CursorAI tools to work with the code quickly and efficiently. When I prompted it to cleanup an implemetnation the tool sayd i…

I have auto mode working on projects with millions of lines of code. Code size doesn’t matter, you just need practice, “guiding” the LLM’s.

Ive always heard to keep each code project file..like under 800. That is interesting. do you have any recommending reading, .cursorrules or any helping materials to work better with Cursor? Thank you!

Copy paste into chat the section from big files you need to work on. My core logic files I max out at 800 lines, I have lots of callable utilities that are 200 - 300 I installed MSYS2 to get access to a bunch of unix utils that make agent more effective on a Windows platform - MSYS2 Legacy codeba…

Honestly cursor itself is going to be the best teacher, because a lot of what will work better depends on your exact projects. But the core principle is LLM’s hallucinate, code doesn’t so use cursor to make a bunch of python tools to allow cursor to do things better. Also documentation is king. Ever…

Craft your documentation in a hierarchy of Cursor Rules .mdc files and use thorough descriptions with Intelligent State selected and any model will find its way pretty fast around your codebase - I am 25 - 30 percent documentation versus code

Cursor models have a great semantic search tool. Thanks to it, if the model knows how to use it, they independently and very quickly get the context from the entire repository. As for file length, it depends on the project. It’s generally considered good practice to keep scripts under 500 lines. Bu…

I just noticed about this week where I was building a contract management react app and it was just working beautifully flawlessly. Then I got it to about midweek and then all the sudden the model just started being super inefficient. It could be because I’m in auto mode and it’s constantly picking …

For optimal performance with CursorAI tools especially when working on React apps. It’s best to keep individual files under 300–350 lines of code. This allows the AI to parse and edit efficiently. In your .cursorules, consider enforcing modularization split logic across components, hooks & utilitie…
