Let Codex call Codex recursively

What feature would you like to see?

I prompted Codex CLI to generate thoughtful AGENTS.md files in each subdirectory of a codebase, describing the code in that subdirectory and a summary of its own sub-subdirectories.

Currently Codex CLI says "I realize I can generate content as GPT, but I can't call myself directly in a script.".
See the screenshot below:

Could you please add a CLI flag like you already do for e.g. --search, but in this feature the flag would be e.g. --recursive that allows Codex to call itself for subtasks? This would let Codex run Codex in a Divide and Conquer or Dynamic Programming manner.

Additional information

Optionally, you can also add --recurse-parallel=N flag that would let Codex launch Codex subtasks in parallel up to N simultaneous Codex program instances. Use N=0 for as many Codex instances as there are logical CPU cores in the system.
