It looks like Claude tokenizer handles markdown pretty efficiently, like a ## header is like 1-2 tokens. So I think the actual token savings are smaller than the byte-level numbers suggest. Where this actually matters is if maybe if you're on Haiku with big codebases where system prompt and context fight for space. On Opus? Probably not worth making your files unreadable for humans?

Good callout on the tokenizer — I was measuring character reduction, not actual token savings, so the real gains are smaller than the headline numbers suggest. You're right that this matters most at the edges: Haiku, large codebases, or heavy memory systems where the context budget is genuinely tight. On Opus with a simple project CLAUDE.md it's probably not worth the readability hit.
