Codex doesn't read Claude.md like Claude does. It's not a "one line" change to switch.

I have a CLAUDE.md symlinked to AGENTS.md

ln -s CLAUDE.md AGENTS.md

There's your one line change.

		That doesn't handle Claude.md in subdirectories. It does handle Claude.md and other various settings in .claude.

You mean Anthropic are the only ones refusing the de-facto standard despite a long-standing issue: https://github.com/anthropics/claude-code/issues/6235

And as others have said, it's a one-line fix. "Skills" etc. are another `ln -s`
