Founders/Builders that use Claude,
Hows everyone else finding Sonnet 5 sofar?
I destroyed 13 commits and my Stripe integration today.
I didn’t review the code. I didn’t understand git. I just pressed enter.
I thought Claude made me a dev. Today it made me someone who can break things at superhuman speed.
Backup branch saved me. Reading would have also saved me. One of these requires effort.
What’s the worst thing you’ve blindly run from Claude!?
Motifkit launch was rejected by @jackfriks , along with some really valuable feedback!
Very excited to make some fixes and resubmit!
☠️❌ the crew rejected another startup
@yinsured's startup Motifkit was sent back to port by @jackfriks.
why:
"hey, this is a real product and the niche is solid, but I still have to reject on conversion clarity and trust.
- the main issue is the hero overpromises a bit. 'turn musical ideas into full orchestral compositions' sounds like magic composition generation, but the product seems to be a browser sketchpad for building and exporting orchestral MIDI - also no need to put name of product in the headline, people do not need to know name of product, they just need to know what it does, they are already here on landing page.
- make the first sentence more literal. say exactly what it is: a browser MIDI sketchpad for writing chord progressions, melodies, and orchestral arrangements
- show the actual editor much bigger above the fold. right now the first-screen demo does not give me an instant product AHA (Keyframe thumb is just landing page)
- add proof near the top: a real composer quote, example outputs, or founder credibility. for music tools, trust matters a lot -- also the demo doesnt let me track ahead to skip anything, would allow for that.
the product itself seems useful, I just want the first screen to sell the real thing more plainly and credibly."

I just submitted Motifkit for review on Ship or Die 🏴☠️
It took me 12 days to ship in public and submit proof.
Follow the mission on my profile:

This is my first time ever launching something!
@marclou and @jackfriks set a challenge and I couldn’t resist.
