This was my first real wow moment with the new Codex app + skills + codex-5.3. I was able to ship a playable, physics-based sim even though I’ve never built a game before!

Powerful new design pattern I’m experimenting with.
MVC: Model, View, Codex
Define the model and build persistent storage, design the front end, encode the business logic + API schema as skills/plugins. Then just chat with Codex + in-app browser. Works surprisingly well!
To this day I still don't understand why there is no ChatGPT or Claude or any other voice app on the Apple Watch, even though it looks like the perfect form factor.
@jxnlco@dkundel Great read, doing lots of similar things.
I’ve been goal-maxxing lately, one pattern I use: “write x number of lines to a research.jsonl file then deliver a report.md file, keep goal.html updated”
jsonl is easy to count lines, so forces deep research before goal
And I’m not talking about point of no return to Claude Code. If they release a model that’s better, great.
I’m talking about using an agent interface (super-app) for ALL tasks.
I don’t go to a browser anymore. I don’t go to email. I don’t go to notion.
Every task that is started is kicked off via an agent chat.
I believe over the next year this is inevitable for all knowledge work.
If your app doesn’t open in the superapp browser you may be…
Cooked.
The incredibly powerful new GPT Image 2 model from @OpenAI is live on OpenRouter as openai/gpt-5.4-image-2
Using OpenRouter's GPT-5.4 Image 2, you get the image gen capabilities of Image 2 alongside the prompt improvement of GPT-5.4.
We had early access to GPT 5.4 to benchmark on @tryshortcutai and it is extremely good at Excel
Here is a quick walkthrough of two real-world tasks in our internal eval of 50,000+ cells each
Watch, because the industry is way beyond the same flashy and meaningless DCF demo

p.s. I have to shout-out my inspiration for this game. 1985's classic "Winter Games" for the Commodore 64! So many hours trying to time it juuuust right to hit that red flag!
But overall, it was very fun to build a full working game end-to-end and Codex is surprisingly good at making games.
Give it a shot! My high score is 112. If you beat it, reply with a screenshot 😄

Oh no way it worked lol. Shoutout to ClawVault for the "primitives" idea. It even one-shotted out a swift app for the menubar, and just for fun I made a Remotion video of the readme! 😂

Weekend project - cron job to screenshot my laptop every five seconds, then use a codex automation to take notes and eventually create skills for my repetitive tasks.
