Nice. I have an X4 that I can try this on, currently waiting on an X3 to arrive so it actually clips to my phone. Great bit of hardware, and this project looks very fun.
While you aren't getting consistent, usable results from your setup you shouldn't allow it to many any changes that you disagree with. For every change it proposes, review thoroughly and tell it what you'd prefer instead. It will get better during the session, and you can ask it to codify the rules you've communicated implicitly in the CLAUDE.md file.
Thanks for posting the detailed instructions. I'll be trying this myself. I discovered a technique that lets you use orthostatic pressure combined with breath to seriously alter my mental and physical state within seconds, and this was after years of casually trying other breathwork. In the field of self-development, the only empiricism is actually trying stuff. And it's usually a field of great personal invention.
