This is not AX (agent experience) friendly (and for some humans here too).
There is no "why" or "when" to use it in the documentation. We humans need to figure out why this is needed at what occassion to AIs.
So my point here is the bad README.
If there is an ambiguous in the doc, and what you conside ris "obvious" is not obvious for some. It's a bad doc.

If I were to use this, I first have to instruct, hey Codex, for low-level API calls to bypass your harness,
1. Read docs on OpenAI CLI: (and you provide why Codex would need it) 2. install OpenAI CLI 3. Call low level APIs: instruct when to do this over going thru codex harness
