I tried doing the math here: README is 1,265 tokens with OpenAI's o200k
tokenizer and 2,403 with Claude's.

Measuring the common CLI agents, the first request is about 14k to 15k tokens
before it reads anything, and the one line Makefile change that I used as an
example took between 88k and 118k input tokens per session.

This is sort of already what README is, no? it's just an index pointing to our
documentation without much actual content otherwise.

I suppose there are parts there that are completely irrelevant to someone using
an AI agent, but those seem to be quite minimal. Is it worth the overhead of
maintaining yet another doc index?
