Copy and paste this into your codex: “Look through my recent Codex sessions and identify repeated workflows or repeated asks. For anything I keep doing manually, suggest: 1. a skill if it is a reusable workflow 2. a custom subagent if it is a bounded role or investigation task Focus on practical things like CI failures, PR reviews, changelogs, docs updates, release prep, debugging, and test triage. Create the useful ones only. Keep them simple.”

You might believe you should spend less time thinking about code because of AI. I strongly disagree! We’re watching this play out live where tons of AI generated code becomes a liability. At the end of the day, an engineer needs to be responsible / on call for code that gets shipped to production. If you don’t understand the system you’re trying to debug, you’re probably going to have a bad time. Yes, AI can help with all of this, if you set up the proper systems. You can have agents triage prod logs, look at errors, etc. You can speed up parts of the investigation, but an engineer needs to make the call. There might be serious customer or financial implications from that change. I expect the trend continue for trimming dependencies, vendoring code so you can modify it directly, preferring simpler systems with fewer abstractions, and spending waaaay more time thinking about system design and code maintenance. I’ve said this before, but it’s a great time to get familiar with CS fundamentals and some of the history behind what great software looks like. Many parts will be different in the coming years as AI progresses, but also a lot more than people realize will stay the same.

trying to remember what it was like to code before codex

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

We found and fixed two issues that could explain this degradation of the capability of GPT-5.5 in Codex over the last ~ 48 hours. We are monitoring over the coming hours to fully confirm and I will reset usage limits this evening. Apologies and now is the time for /fast maxxing.

The fact that two designs look alike does not actually mean its stolen work. Im not referring to outrightly copying shots. I mean someone posting something that looks strikingly similar to yours. It doesn't mean they stole your work. Or your content. Design is basically mirroring the world. If we all take inspiration from the same places, we are only bound to do similar things over time. Yes there is a whole world of things to design but we are also constrained by industry, briefs and almost serving the same people which means, overtime, we are bound to converge on the same answers. Also, there have been lots of "industry standards" in interface work (unlike brand design) which would make it seem like our hands are slightly tied for like 20% of the choices to be made. That said, don't steal other people's work please.
