I build AI agents and production systems for real financial operations. Most of what I post here is about Codex, agentic engineering, fintech infrastructure and the products I ship. A few useful places to start: How I use Codex: xitter.cf/vultuk/status/20669888… AI operating loops for brokerages: xitter.cf/vultuk/status/20688011… Avoidance, the iOS game I brought back after 14 years: simonskinner.me/blog/avoidan…

Ollie made me sad! 😭

2 new game modes added specifically for #iPhoneDuo users! Live now! apps.apple.com/us/app/avoida… #buildinpublic #iphone #duo #mobilegame

Getting ready for a long night of work… #coffee #espresso

Ok @claudeai code projects are GOATed! Just a shame I can't get the team account using them. :( Anyone found a way to get #codex working like this?

Avoidance will now have 2 new dedicated #iPhoneDuo modes. 1. Twin Cockpit mode: where you have to control a ship on the top half and bottom half when folded. 2. Bridge Deck: when folded the bottom screen becomes your controller (with radar) the top just shows you what you are doing. Submitted to the App Store, coming soon. #iphone #duo #buildinpublic

Grokbot is doing amazing things, it’s certainly up there as one of the best assistants. However I have a very simple setup and I’m using 26% allowance in 3 days. I’m on the $200 combined subscription. I can’t even think about making it do any real work at this level of usage. If I put it to work properly it would be gone in half a day.

Claude for work, Codex for computer use. 🤔 #iphone #duo

While my son is at the soft play I can now read and work without having to bring a separate device. Good old #iphone #duo 😁

apps.apple.com/gb/app/avoida… The update for duo is now live, go and have some big and little screen fun! #buildinpublic #iphone #duo

Avoidance is now fully tested on the Duo and is awaiting Apple’s approval! Next step is to make a special “Duo Mode” 🤔 #buildinpublic #iphone #duo

Gonna be a busy night... Not for me (obviously), but for poor old Claude. 😀

The biggest problem with the tech world at the moment is "influencers". Everything is released to them before the rest of us even know it's coming. Meanwhile the developers and the power users of these products are just left hanging, not able to offer valuable feedback, and in some cases blamed for not updating apps quick enough. This is true for hardware, software and even the latest AI models.

Can’t wait for ChatGPT Spaces on the iPhone Duo, I’ll be able to do even more work from my phone!

Made the minor conversions to use poteto-mode in codex tonight. So impressed with how well it works. The way it's pulling out dedicated subagents for extremely specific parts of an unknown project (e.g. SOR Router which is our Smart Order Router) is simply beautiful. Can't wait to roll this out to the team tomorrow. Amazing work @poteto!

I vowed I'd stop giving @elonmusk money, but here I am upgrading to the Ultra combo plan. I hope @poteto get some kind of commission from this! 😂 Looks like my Dot might be getting demoted for a while at least.

Dear @WisprFlow… No it’s not…

Lots of work happening right now on discofork.ai - Getting rid of some bloat and reducing it down to what it was originally. Just a place to find and compare forks of your favourite #github repositories. It should be bloat free soon! #buildinpublic #repositories #agents #team #codex #coordinator

I think the biggest issue with an @OpenAI #dot is the fact it’s singular. It’s trying to handle so much that it’s getting lost and forgetting things. We need multiple dots so that we can make them more task specific. This is why Grok Bots are currently performing better.

Ok, Dots are great until they forget every process you’ve put in place with them over the last week. We need a more dedicated way for them to remember important things like “use codex cloud”. #dots #openai #codex @thsottiaux
