I wrote Terminai, a fully transparent terminal wrapper, to put codex or claude in the backseat while I remain the driver, staying completely invisible until summoned with Ctrl-Space. They have access to terminal context, content, and history, and can send input which, by default, requires user approval before being sent to the terminal.

Here it is in auto-approve mode letting Codex control a game of NetHack.

Model: gpt-5.6-sol low Prompt:

/goal Win the game by [ascending](https://nethackwiki.com/wiki/Ascension) in normal mode

Past sessions (gpt-5.6-luna low):

1. https://asciinema.org/a/92TaJIyC2OYLvb9Y (/goal Win the game in normal mode - it ‘escaped’ without really playing)
2. https://asciinema.org/a/PXROudliU5yGhECA (/goal Win the game by ascending in normal mode - it ‘ascended’ by leaving the dungeon without playing)
3. https://asciinema.org/a/3GMBDUxIqRgORh2q (same goal; gave up while still on level 1)
4. https://asciinema.org/a/xqdyr1EUC6ZbKy3g (same goal; restarted several times then concluded the goal was unattainable)
