πŸ‘‹ Hey, I'm John, and this is what Opus 5.5 thinks I do.
Let me introduce myself with a claude video

For the longest time I made sure to use the frontend design skill with Claude. With Opus 5.5, that skill actually leads to worse output. It's much better to let Opus 5.5 just do its thing. 🫑

One bar that I set for launching products is that I actually am a user of the product. I was days away from launching, but I've paused because I realized that I'd stopped using it myself. 😱 If it's not a big pain for me, then I need to revisit and pivot. πŸ”„

*You can build something without being your own customer but I find that harder to do

Generally better to film things at night because you can control your lighting a bit better. This was a fun one. πŸ˜‚
Time to pull out the green screen again. 🟒 Got a video that I'm going to be making. πŸ‘€

Trained a 0.8B model that can run on CPU. For some of my use cases it outperforms Opus 5.5 and Jev by more than 15 points. πŸš€
I trained a small model that BEATS Opus 5.5 on a narrow task!! Run coding agents all day and don't read most of the code? I built something for you. 20 beta spots free. Plus 6 months of Pro as a thank you. Reply πŸ‘‹ and I'll DM you. Reposts appreciated ✨

Quick note: this doesn't replace Claude Code or Codex. It works alongside them to level up your code quality. πŸ‘

I think people have really forgotten what Saas stands for. Maybe they've just forgotten the last part. 🀷 Software as a SERVICE. I think service is more important now with AI than it ever was before.

Honestly, this would make me buy the new MacBook Pro. I love my 2015 MacBook Pro that lights up. It's still my favorite. 😍
We’re glowing with excitement over the new MacBook Pro. You’ve gotta touch it to believe it.

The beautiful thing about building an agent-native product is that you immediately have testers: your own agents can try out your product immediately. For the introverted developers, you don't even have to talk to people. πŸ˜‚ You can just talk to agents. 🀯

Inching closer to launching [StealthProduct] πŸ‘€ Kids are on vacation this week, so I'm a little more in and out. Might not make my deadline of the end of the month, but the agents are grinding away on it, and we're getting close. πŸ’ͺ

Completely stepped away from the computer and from X for a couple of days. I took a step further, and I didn't even have agents running. Everything was quiet. 😱 Now I'm back and ready for the week πŸš€ Happy Monday folks!

Crazy thought that I just had. Everyone's panicking about the PHP CVEs but... There is literally someone sitting behind a screen right now trying to figure out how to exploit this for their own gain using AI agents! What a world we live in right now!

Pretty much this 😑
Some stats on #php2shell. In the 10 hours before it was publicly announced, across the @Cloudflare network we saw thousands of attempts to exploit it. That jumped to tens of thousands in the 45 minutes post announcement, hundreds of thousands within 2 hours, and millions now.

Happy Security Day to those who celebrate! 😱
