If you want to see an example on how having the very best AI model and harness doesn’t result in better/faster execution - in fact it slows you; It took the Claude Code team 16 months LONGER (!!) to add support for AGENTS.md than OpenCode & Codex, 12 more vs Cursor Quoting @trq212 We're adding support for AGENTS.md to Claude Code. Starting today in version 2.1.277, if there is no CLAUDE.md in a folder, Claude will check for and use AGENTS.md. You can toggle this behavior in /config. Anthropic Related

Echoes of OpenAI renaming the Codex desktop app to "ChatGPT" here - everyone's racing to establish themselves as a general agent now Quoting @mikeyk Claude Cowork and Chat are now one Claude, starting today. The most common thing we hear: people aren't sure which product to start with. That friction gets in the way of getting the best from what these models can do. I've been on the unified version for a few weeks and really enjoy it. Claude doe… OpenAI Related

This is so useful. pushing to add this to codex as well. Quoting @Pat_Erichsen as you become more ambitious with coding agents, delegation becomes increasingly important the new "suggested task" feature in @openclaw gives your agent a tool to do this for you if the agent identifies a sufficiently well-scoped piece of work, it will recommend kicking off a new session to work o… Related

🌶️Codex can do a anything Muse, Bot etc can do quite easily I get the appeal in the form factor “less is more” but if you are already a codex desktop and are a power user (computer use, remote access, thread management, voice control etc), YAGNI I still like playing with the other things for educational purposes but also need to avoid tool sprawl unless there is a real benefit Related

did you miss my ai engineer talk? i'm doing a slightly updated version about how i use codex to automate a lot of my work so i can focus on even bigger projects, work more closely with people, and think higher level 1. how to bring context into codex 2. how to get work done 3. how to give codex the power to do anything on my computer sept 10th 2pm EST maven.com

Unexpected Codex use case: set up an Android handheld for me. @johnvoorhees got me into this: enable USB debugging and just let the agent rip. Codex installed Cocoon frontend on my AYN Thor, transferred all my ROMs, and is currently configuring emulators, mods, and other apps. It's just working in the background and cross-referencing YouTube/Reddit sources to set everything up, so I can focus on cooking for the family instead. Incredible. @dimillian Related

And I really do think that two agents are better than one. So, what's a good example? When I have Codex interact with another agent, it can give so much more context about me and what I want than I would be able to type.

It is, it is powerful, but in many ways it's not much different than if I run cloud code with dangerously skipped permissions or codecs in YOLO mode, and every, every attending engineer that I know does that, because that's the only way how you can, you can get stuff to work.

Some other comparison is like, Opus is like the coworker that is a little silly sometimes, but it's really funny and you keep him around. And Codex is like the, the weirdo in the corner that you don't wanna talk to, but is reliable and gets shit done.

I particularly like to combine this with slower, more thoughtful models like Amp's deep mode (which is basically just GPT-5.2-Codex) which can take upwards of 30+ minutes to make small changes. The flip side of that is that it does tend to produce very good results.

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
