I kept mashing 1 to accept changes in Claude Code, so I automated it. It spawns your command in a PTY and pipes "1" into stdin on a loop.
npm install -g press-one
press-one --delay 3000 claude "fix all the bugs"
Known "features": a slow stream of 11111 appears while the model is thinking, and you can't type because stdin belongs to the machine now. Zero dependencies (just Node + Python for PTY allocation). MIT licensed.
