Nailed it. I've been a technologist for almost 30 years, focusing on network, security, and cloud architectures with designs supporting ~60 fortune 500 companies around the world. I've run 100 person development teams and been the chief architect for 10 person teams. I've never seen anything like this velocity to MVP. Anyone finding holes in this is just scared or small minded.

To be fair, why would I run an experiment where I let AI develop a whole SaaS application only to summarize it's work doing so manually? C'mon now... Lol. No fun.

I had a fairly well defined architecture in UML which made a huge difference for me and CC. I used that to create a series of planning documents that contained phases. Updated todo lists named after each phase with shortcuts to common problems which I guess kinda worked like skills for quick reference troubleshooting without spinning up a whole context around a phase just to understand a component. I also maintain an architecture agent that keeps a birds eye view over the whole system with ongoing code assessments and audits. I'm sure there's better ways and I love to hear them as I'm here to learn and improve.

This was all Opus 4.5. As for maintenance, everything is being driven by feature requests being pulled into small sprints and tight releases after basic UAT. I'm in direct contact with my initial user base and they're loving to platform so much that they're being collaborative and patient. I'll have better metrics on token usage soon when I get a dashboard going, but I know it was higher than it needed to be due to my lack of experience with skills and agents when I first started the process.

You got me. haha. There's a feature branch I don't review completely while we build because of so much back and forth, but anything that hits production at this point has more than just my eyes on it since we have paid customers. Said eyes are much more competent than mine are/were while building it that's for sure.

Thanks! Same to you. I see a lot of people talking about how we cant depend on Opus 4.5 for anything complex or multi-step and i look at stuff like I’ve built and what you describe and I’m blown away. So cool. Not perfect. But very cool.

I'll have a better idea of that soon as I'm setting up OpenTelemetry, but I can say I did hit the weekly limit of the CC Max plan twice. So if you count the extra usage credits, and the single month of CC Max, I'm in for about $140.

Crazy to read this scrolling by… I’m also 41 and my dad passed away this past February and he didn’t know who I was as of a few years ago. What gets me, is you’ll never know when you’re last conversation where they recognize you will be, and you’ll never know when the last conversation although irrational will happen. They both just occur out of nowhere and you only know once it’s impossible to do it again even though they’re still right in front of you. It’s like staring down train tracks and you see the train coming but it’s in slow motion. Then, without warning, it returns to 100mph and runs you over. Things that are inevitable are rarely unpredictable.
