Grep-and-replace? You mean, sed? People burn tokens instead of using sed? Honest question.

Ugh. This is peak AI influencer. It’s a 21 page AI-generated presentation and an AI prompt for:

npm i -g @musistudio/claude-code-router

So it looks like the person who set up this GitHub repository didn’t even make the software that does all the actual work. They also never mention the original author in the README. But, of course, their AI prompt includes instructions to open their homepage, so this is effectively using the AI prompt for indirect advertisement. The HN submission title is also misleading. I didn’t see any maths in the repo.
