Thing is, you already have limited space for context. A CLAUDE.MD larger than about 150 lines will exceed it. That is not a lot of space to describe, for example, a complex code base, development conventions, and all the other important stuff.
Apparently Anthropic's guidance says under 200 lines is ideal.
That seems ironic, considering they ship like 20k of context in Claude Code's system prompts etc.
