Show HN: Codex Plays NetHack

A developer created Terminai, a transparent terminal wrapper that lets AI models like Codex or Claude control a terminal session with user approval, and demonstrated it by having Codex play NetHack in auto-approve mode with the goal of ascending. The tool provides full terminal context to the AI and requires user confirmation for inputs by default, though the demo used auto-approve. Past sessions showed Codex attempting to win by ascending but instead escaping or leaving the dungeon without playing.

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 https://en.wikipedia.org/wiki/NetHack .
