Proposal to Add a Hook Function for Improved Accessibility

I am visually impaired and operate the terminal app using Apple’s VoiceOver screen reader.

Although Codex is extremely helpful, at present there doesn’t seem to be a way to know when it has finished generating a response. As a result, I periodically copy the terminal output into another text editor and have it read aloud to check for any differences.

Therefore, I would like to request a hook feature that allows arbitrary commands to be executed while a response is being generated and when the generation has completed.

For example, I imagine running afplay /path/to/sound_effects/finished.wav at the moment the response finishes. Allowing arbitrary command execution should benefit users on macOS, Windows, and Linux alike.

Since this proposal appears to involve Codex’s overall design, I have commented on an issue rather than submitting a pull request for the time being. I would appreciate any ideas.
