Here’s your monthly reminder that you shouldn’t be prompting coding agents anymore.

You should be designing loops that prompt your agents.

[Peter Steinberger 🦞 @steipete]

Folks: when you write skills, ask your agent to be token efficient, relax grammer. I see too many skills that write books in the skill description, and all that crap is loaded into every context.

I wrote a skill that finds the worst offenders. https://t.co/kfaaJpxMXE

You've been asking for this one...

Now in preview: Codex in the ChatGPT mobile app.

Start new work, review outputs, steer execution, and approve next steps, all from the ChatGPT mobile app. Codex will keep running on your laptop, Mac mini, or devbox.

[OpenAI @OpenAI]

Codex now works directly in Chrome on macOS and Windows.

It’s even better at working with apps and sites in Chrome, and now works in parallel across tabs in the background without taking over your browser.

To get started, install the Chrome plugin in the Codex app.

[Andrew Ambrosino @ajambrosino]

new: Codex can now drive tabs in Chrome, working in background tabs alongside you. Get the new Chrome extension today.

also: we shipped a ton of performance improvements in the app. should feel a lot better.

happy codexing!

@HydratedViper_ it eventually finished

[Vincent Koc @vincent_koc]

I've been using /goal for ~3 days on OpenClaw.
- 13 runs.
- Gazillion tokens.
- Many, many PRs.
The lesson isn't "i used /goal a lot." it's that /goal is not a "do my ticket" button.
It's a constraint workflow. I want a keep the ship on course. A thread on what actually works 🧵

[Christof Salis @christofsalis]

So I have been testing the windows version of the codex app. No bluescreens so far which is nice.

Heads up, it does require your modem to be dialed up at all times. That's a bummer because I was expecting the AI stuff to be included with my local MSDN install.

Hello builders. What are we getting wrong with Codex, what can we improve?

[Derrick Choi @derrickcchoi]

A useful pattern in Codex that I like is giving it its own CLI.

If Codex keeps doing the same work against an API, log source, or team script, a small composable CLI makes that workflow more reliable and reusable.

cli-creator builds the command
skill-creator teaches Codex when to use it

The Codex app server was such a brilliant stroke of foresight that really doesn't get enough love

Not only are you allowed to use your chatgpt account with any harness, but you can build your own apps directly on top of theirs.

They just make building on and with codex such a great experience

To demonstrate this utility, I want to highlight the kitty litter app, made by @SIGKITTEN.

Instead of having to build the entire harness, and all the infrastructure, he's plugged into the app server for a unified experience between mobile and dev machine.

When I create a session on my computer, it's automatically available on my phone. All of the chats you see in this video automatically populated when we connected to the app server.

All my skills. My agents. My sessions. My folders. My prompts. They're all ready to use - automatically.

Because they're exposed by the app server, along with many other endpoints.

It's a great ux/dx that really deserves some love.

It's almost like they want you to build on top of their products ;)

Btw Litter is great 👍

While I think what Anthropic does is sad for the ecosystem, I wanna give Boris credit for doing what he can to soften the fallout.

Today's release will include some fixes for better cache use, to lower cost for API users.

[OpenAI Developers @OpenAIDevs]

Hello. We have reset Codex usage limits across all plans to let everyone experiment with the magnificent plugins we just launched, and because it had been a while!

You can just build unlimited things with Codex. Have fun!

[OpenAI Developers @OpenAIDevs]

We're rolling out plugins in Codex.

Codex now works seamlessly out of the box with the most important tools builders already use, like @SlackHQ, @Figma, @NotionHQ, @gmail, and more.

Automations are now GA.

You can now:
• Set the model and reasoning level
• Choose if runs happen in a worktree or existing branch
• Reuse workflows with templates

Automations are great for recurring tasks — daily repo briefings, issue triage, PR comment follow-up, and more.

[Guinness Chen @guinnesschen]

You can now summon Codex from anywhere on your desktop. It's easier than ever to reach for Codex.
