I'm joining @OpenAI at the end of the month, and I can't wait to get started! I'll be working on everything related to Codex, bringing what I learned building Codex Monitor, and working with the developer experience team!

Just Codex

The future is literally at our fingertips. I believe we're almost there with the model if we build enough tooling to become autonomous around it. And if we're patient enough, we'll get the model that will do all of it itself anyway.

Thomas Ricouard @dimillian.app · 06/02/2026
But this will be solved soon. If I had enough time, I would code an autonomous Codex GitHub agent that basically takes issues one by one, implements them, tests them, or closes them.

Thomas Ricouard @dimillian.app · 06/02/2026
What's the point anymore? Codex literally reviewed 500+ open issues, grouped them, and sorted them for me in less than 3 minutes. Everything became easy. It's just a matter of will, drive, and ideas. The only bottleneck is me having to manage all that

I keep seeing people say they'll get rusty if they let the AI write everything. Well, the truth is that you can't compete anyway. It's time to sharpen your agentic skills rather than refine your decades-old programming skills.

It’s a bit like that the point? You can still read the code and steer it to what you want the code to be. But writing code in itself is already almost all gone

Thomas Ricouard @dimillian.app · 03/02/2026
One thing that didn't change with agentic programming is that good software is still obsessing over every little detail. Both technical and UI based. That's still the fun part for me.

Thomas Ricouard @dimillian.app · 03/02/2026
And I'll continue to maintain mine; both can cohabit. I don't see a problem with it. And the Codex team has been amazing with all the feedback they've gotten on their own app, and it's already steadily improving!

Thomas Ricouard @dimillian.app · 03/02/2026
All in all, it's a very solid first release! I can't recommend it enough; this is truly the flow of the future, and I'll only improve from there. It has many different features from Codex Monitor. I see my own app as a simpler/leaner version of the Codex official app.
110
Thomas Ricouard @dimillian.app · 03/02/2026
And it also has all the features you expect from this kind of new, agentic-driven environment. A sidebar with the git diff changes, a terminal, a way to quickly add and sort workspaces, easy access to all Codex /commands, plan and code mode, etc... And multiple run commands!
110
Thomas Ricouard @dimillian.app · 03/02/2026
About worktree: the Codex app has a very cool feature. Once you have changes on a worktree, you can sync the change to your local repo, it'll create a branch for you and keep it in sync between your worktree and repo. This is amazing and makes Worktree much better to work with!
110
Thomas Ricouard @dimillian.app · 03/02/2026
Another feature they have is automation! You can create an agent cron job that runs on a specific day at a specific time. In my case, I have a daily review of my open PR and issues, but what you can do is pretty limitless!
100
Thomas Ricouard @dimillian.app · 03/02/2026
Another awesome feature is that you can easily start new agents locally, in a worktree, or as a cloud agent. To me, that's a super powerful feature! Your worktree and cloud agents are combined in the sidebar. And you can easily apply cloud/worktree changes on your local repo.
100
Thomas Ricouard @dimillian.app · 03/02/2026
You can also manage and edit your skills and install new ones from an ever-growing marketplace of skills! Also within the new Codex app! Can't wait to see where this will go. Skills have been a bit messy, with a ton of libraries and repos all over the place.

Thomas Ricouard @dimillian.app · 03/02/2026
You can see all your agents' threads per workspace in the sidebar and quickly switch between them. It has most of what I ever wanted from those new kinds of agentic/orchestrator IDEs. And no, no code editor, we all agree on that!

I've been testing the Codex official macOS app for the last couple of weeks. Yes, funny, I know! But I didn't know they were making their own until a week after I started and released Codex Monitor! It's OpenAI's take on the IDE of the future, and it's pretty good! 🧵for more

For those who are not terminally ill, I've created a macOS Codex Application that can manage any number of agents across multiple projects with a sleek UI. And of course it's fully open source! github.com/Dimillian/Co...

It’s a small trick I used for the conference. It’s not Claude but cursor auto completion model which inferred it. Because I created and deleted the project multiple times in the same folder cursor had cached previous attempts.

If I do a PR to fix it you’ll do an iOS 26 version?

Thomas Ricouard @dimillian.app · 01/11/2025
IMO not a blocker. But weird issue. Is it some interaction with Expo? In SwiftUI some sheet takes the source view position for animating.

I’m on X and I see the retarded White House posts, the fat JD meme and the massive no kings protest. And I’m here and I see the same things. I think it’s how it should be.

TBH I don’t think blocking is a good idea. You need to see the stuff, you need to know about it. Blocking something online doesn’t make the problem disappear. It just makes him think you live in a fairy tale. And it’s not real.

Never forget that this is the best UX you can get because Apple can’t bother to make text selection work on SwiftUI Text.

So how you’re liking Pokemon Legends ZA? I think it needs to be the new default combat. It’s just so much better and engaging. But the city is just so bad tho.

But there is no chronological timeline in the For You here. That would not make sense. For the following yeah.
