If you haven't set up Agents.md in Codex yet
you can just copy the homework from Andrej Karpathy.
Here's the exact setup (takes 2 minutes):
1. Go to his repo
2. Copy the 65-line Agents.md config
3. Paste it into Codex App → Global Custom Instructions
4. Done. You're already ahead of 90% of Codex users.
It's minimalist. It's effective.
Bookmark and Save it no matter. It'll be the most productive thing you will do this weekend
