I haven’t checked the code yet, but what does the “Claude Mode” mean? Is it a poor naming choice? It implies that the local app is somehow connected to Claude (?)
Right now I'm using a vision library to detect head height which was good enough. I went down a tangent where I hooked it up to my Claude Code instance to take a screen shot and have Claude Code assess how bad my slouch was. Claude would watch a folder for screen shots, read it in, and if it detected bad posture, write to a file the program was watching to adjust blur.
I did this weird work-around so I could use my Claude Code subscription as opposed to the API.
Anyways, it was too slow and Claude was a bad judge of slouchiness. Head height works well enough!
I'll clean this up.
I luckily won't need such feedback loop anymore, had some mild lower back pain show up over 10 years ago and bought a chair without a backrest that, after 3-4 weeks of struggling, trained me to sit up straight. Now I have some random cheap office chair with a backrest, but I rarely lean back to it. Funnily, I was going to give up using that "backrestless" chair after 2 weeks of inconvenience, but decided to give it one more week and then the magic happened :-) Mild lower back pain automatically gone.
But what I have now is this:

Just don't assemble the backrest at first. If sitting up straight, I just lean wrists on my keyboard wristpad and part of forearms on the desk, no armrests needed either.
Edit: I still use my height-adjustable standing desk, but now it's value is that I could adjust it for the perfect height for my sitting-up-straight position (so no chair armrests needed) and it's been fixed at that height for the last 7 years...
The one I have does have a backrest but because of the way it's shaped you don't actually use it to slouch. It's more there to support when you lean back and want to take a break from typing or something like that.
Same with a codebase search for "anthropic"
No back problems as there's no weight on my spine. No carpal tunnel issues, as my wrists are always flat. No fatigue from holding my body at right angles for hours at a time.
The downside is I look like a total slacker in the office, especially to narrow minded image conscious managers who expect me "to act professionally."
Congratulations! I love seeing people express themselves to release things that were previously not economically viable to prioritize
Forget worrying about a 10x dev, Claude Code with the Opus 4.5 model has turned me into a 100x developer even in software stacks I'm not even familiar with. And with playwright-mcp its completely absolved the need for UX designers in my workflow because I just point playwright-mcp at an already established and A/B tested website for its UX principles. This gives me results far beyond what v0, lovable or Claude Code would come up with on its own.
For example, even if you sit perfectly upright, if you have anterior pelvic tilt, it can change the whole dynamics of your spine, that the cervical segment takes a lot of load that it isn't supposed to do.
Or with bad habits you can reprogram your neuromuscular system that it uses the wrong muscles to maintain posture, that can lead a series of problems long term.
If you have back/neck pain or tension that does not resolve in 1-2 weeks, go to a physio.
ps -- I added two feature requests and commented on another on the repo.
