You: I want to add photo upload for sellers.
/plan-ceo-review
Claude: "Photo upload" is not the feature. The real job is helping
sellers create listings that actually sell.
What if we auto-identify the product from the photo, pull
specs and pricing comps from the web, draft the title and
description, and suggest the best hero image?
That's a 10-star listing experience. "Upload a photo" is
a 3-star one. Which are we building?

One feature. Six commands. CEO taste → architecture → review → ship → QA. The agent found a race condition I would have missed, auto-fixed two issues I didn't even think about, wrote 9 tests, and generated a regression test from QA. That is not a copilot. That is a team.

## My journey and why this exists
I have a full time busy job as CEO of Y Combinator. And I am coding a lot. Like, a lot a lot. I was stranded in Austin due to weather and I was coding. My mom was in the hospital and not too lucid for most of it, and I was coding by her bedside too. She's ok now.
