My Codex agent built me a Personal OS in Codex. Then Codex wrote the article about how it built it. Then it packaged the starter repo so your Codex can build one too. Normal Sunday night tbh.

Built LockIn: a macOS focus app for Codex users, enforced by an ugly little goblin. You tell it what you’re working on. It watches local screenshots, asks Codex if you’re drifting, nudges/warns you, then blocks distracting sites via a browser extension if you keep trying to escape. github.com/markmdev/lockin

Weekend hack: Build with GPT-5.5 + Codex. Drop your demo in the replies. #1 by likes: 1 year of ChatGPT Pro 2 runner-ups: 6 months each Bonus: Codex picks a wild card winner. Enjoy!

How I used the stack: GPT-5.5 Pro: product direction, UI taste, launch/design thinking Codex (GPT-5.5 xhigh): implementation, Electron app, browser extension, tests, manual QA gpt-5.4-mini: cheap visual sentinel that summarizes recent screenshots before the main agent decides anything

Is there any trick to avoid Claude Code usage limits?

Feeling codexy today (but in a fun way)

If @tferriss wrote The 4-Hour Workweek today, it'd teach how to scale up token usage to get more done. Mark is one of the top verified tokenmaxxers. He uses tokens not just for engineering & side projects, but to run his entire life. Read his guide on how he does it ⬇️

Hello builders! What did you build this weekend with Codex + GPT-5.5? Drop it below, I’d love to see what you made!

It’s the little things that matter, what are some small papercuts you have noticed in Codex? We’ll fix as many as possible in the next week.

A great prompt from @BusMark_w_Nika: What tech or product was too early for its time and worth rebuilding today? Here are a few that came to mind: 1/ "tools for thought" (huge in early 2020s), seems like llms were the missing piece? instead of manually curating, I just want my ai to manage my personal knowledge. rly liked @MuseAppHQ by @_adamwiggins_ 2/ magic leap -- anyone remember the whale demo? 3/ pebble -- excited for pebble time 2 by @ericmigi! 4/ AI shopping -- fetchr (w23) tried it (@calvinchen @calixo888), rly like the fresh take @bindra_dhruv is trying w/ @zamana_hq, think they're finally gonna nail it! 5/ @Detour by @andrewmason -- imagine walking through a city with a real-time voice agent guide that knows where you are, sees what you see 6/ lots of OLD ideas will be revisited in chip design post-Dennard scaling: photonics, neuromorphic / bio-inspired, approximate computing, non-Von Neumann, etc. 7/ ok this one might be a bit unhinged, but @theranos by @ElizabethHolmes was a great idea? why am I still doing blood tests twice a year instead of weekly at home? Which startups would you revive?

Yeah folks, it's gonna be harder in the future to ensure OpenClaw still works with Anthropic models.

One thing I love about @AnthropicAI is when they launch something, you can use it straight away. Just built and testing my first managed agent minutes after reading the blog announcement... seems very cool!

@thsottiaux I have an idea: make all limits 5x smaller

With Codex the there is quite the gulf in load between peak and off-peak times, and we would like to achieve more of a smoother traffic pattern as that would be a more optimal use of our compute. We have ideas, but curious what you all think we should do? Would more usage during off-peak and surge multiplier during peak times make sense?

I see many people running multiple agents simultaneously. I avoid it. Instead, here’s what I typically do while my *one* agent is running: - Review the code it generates in real time - Watch its terminal output and course correct - Do code reviews for teammates - Reply to email / Slack / Teams - Plan my next steps - Pair with a dev on a different task - Pee So, for me, running a second parallel agent is a last resort.
