What version of Codex is running?
0.2.0
Which model were you using?
codex-mini-latest
What platform is your computer?
MacOS
What steps can reproduce the bug?
Run Codex CLI (rust) and paste in the prompt. I use iTerm2 and tried pasting a few different ways:
- with Cmd + V
- with mouse right click & paste
- Holding Option key (Alt) & then pasting
It works for me when I paste small text but fails for the attached prompt. It might not be the length since I also tried 25 paragraphs of Lorem Ipsum text and that worked (so my guess would be special escape characters?)
What is the expected behavior?
_No response_
What do you see instead?
Codex pastes some code and quits abruptly

It also fails on copy/paste operations for me.
Please try 0.3.0:
https://github.com/openai/codex/releases/tag/rust-v0.3.0
Also available via npm:
https://www.npmjs.com/package/@openai/codex
I'm still waiting for Homebrew to pick up the new version.
FYI, 0.3.0 is in Homebrew now: https://github.com/Homebrew/homebrew-core/pull/229365
As noted, I believe this is fixed. Please file a new issue if this is not the case.
