You got claudex. But do you have fabledex? fabledex.markmdev.chatgpt.si…

If Codex repeatedly reconnects after you send a message or takes 15+ seconds before it starts responding, check whether the task has accumulated lots of screenshots. In my case, completed compactions retained raw base64 image payloads, causing later turns to repeatedly process a huge image-heavy history. Removing those retained image nodes restored 4-8s response times. I packaged the repair for this specific symptom as a skill: github.com/markmdev/codex-th… (Just send it to your Codex if you hit the same error)

Why is nobody talking about this Codex feature? You can select anything in the agent's response, click "More details", and it creates a new ChatGPT chat that already has all the context and just explains the thing to you. It helps so much when you don't understand something in Codex's answer. Before, I'd open a side chat, write a prompt, and wait while it double-checks everything it already knows. Now it's one click, and the explanation is almost instant. And it's not just about code either. If you're learning something new, just use it all the time. It's extremely powerful.

Attending AI Engineer World's Fair this week. My Day 1 saved sessions lean coding agents / AI-native SDLC: Codex, Uber uReview, 1M AI-generated PRs, production code access, Claude long-horizon, Shopify River, Figma, Cursor. If you're there too, what are you prioritizing?

GPT-5.5 Pro coming to Codex soon? 👀 @ajambrosino @jxnlco

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
