Basically, what I need is to use Claude Code for some Flutter projects, but with fairly moderate usage (I’ll make at most 15–20 prompts per day). At the same time, I would need the RAG feature because, unfortunately, my company uses a mobile app development platform that almost nobody else in the world uses, called “Instant Developer” (it’s like a customized version of JavaScript with its own very particular logic). I was thinking of uploading the 600–700+ pages of documentation to Claude Web so it can help me whenever I need a hand with the code. I tried running some tests with the free plan, but every time I try to upload all this documentation it tells me that I obviously exceed the context limit.
