@OmarShahine It’s like magic.

@OmarShahine Omar, what MCP or CLI tool are you using to have Codex /Claude Code use and interact with the simulator?

@OmarShahine /Goal is pretty amazing, does get expensive for complex code though :)

@OmarShahine How much time does it take to write, and how detailed is the PRD for the iOS app?

It's pretty amazing. I use it for a couple of side projects. Had a particularly difficult problem with NVIDIA CUDA across different HW architectures. Goal fixed it. Got runtime down from 300 to 45 seconds. Badly documented combination so it benchmarked and tested a variety of configurations until it hit the right one. Would have been extremely tedious to handle manually or even through repeated regular attempts.

How is the retention of the released apps? Are you getting a return on the time and token (money) you spent on developing the app?

Just curious!

Built one. Basically no usage. Went back to the drawing board.

Now I'm spending time on refining the idea before I start the building process.

@OmarShahine The /goal has been a game changer in getting the tools to just relentlessly work

@Andrey_Esipov Codex has built in computer use and browser for in app viewing.

@OmarShahine We use OpenClaw for most of our development tasks (yes really - it is so we can use it in Slack in Multiplayer mode) - would be great to have better support for long running agents in openclaw, its a struggle today

@OmarShahine This is huge. AI that doesn't just write code, but explores the app, tests it, fixes issues, and finishes the job on its own. Real agentic coding is here. The future of building software just got 10x faster.

@designedbyabin These apps are personal apps for me.

@kevintupper Using Claude Designer is the best PRD. App takes an hour or two end to end. Use Fastlane. That is the secret.

It's so magical to see Codex click the simulator, write code, build, and iterate by itself. The command /goal directly turns the agent into a fully automatic developer, and the efficiency of 45% directly rushing to 100% is too outrageous.

Microsoft's wave of Codex is really fierce. I feel that the real era of agentic coding has come👀

@OmarShahine /goal is the right control here

Keeps the agent focused on finishing, not wandering

@coreyh @OmarShahine Same here. I still prefer the way I communicate on the go using openclaw on telegram and it’s “soul”. But codex is fantastic, I’m conflicted because I really like /goal and the codex plugins. I kinda made my claw run longer “goals” but it’s not the same

@OmarShahine corporations can't scale user feedback like that, codex is a glimpse into what's possible when ai owns the 'try everything' phase

@OmarShahine Curious about what model you're using and your reasoning level? I'm working on a game in a similar way, running it in xhigh +fast mode for two days. It consumed a massive amount of tokens, but the actual results aren't great and it introduced a lot of bugs.

@OmarShahine wait this is actually genius

never thought to just tell it to explore till it's done
