Codex App - A First Look for App Development
|
I had early access to Codex app this past week. The OpenAI team is moving insanely fast with Codex CLI, and watching this new app unfold was incredible. Take a look, and see for yourself. Download link in the video. Codex app feels like the missing IDE layer for the Codex CLI. One-click to open Xcode, run iOS/macOS apps, review diffs, and manage agents. I have mine configured using Makefiles (More on my setup in another email). Talk soon, Paul Solt P.S. Codex in 2026 took all the friction out of publishing an app... |

Hey Reader, My last app launch was a flop. I wrote the App Store copy after I’d already submitted for App Review — and I knew it. If you’re in that same boat, that’s okay. But don’t stop there.

Hey Reader, Agents write better code when they can read docs instead of guessing from memory. A 2026 paper found up to a 20% improvement in first-try code accuracy when models were given the right programming context. So what do you do with that? Don’t rely on the agent to know everything from their training set. Instead, provide tools or local docs that they can reference. Your local docs should include sample code so agents can use the code correctly (the first time). If you’ve ever read...
