Answering Claude Code and Codex prompts from your phone

Coding agents like Claude Code and Codex pause and wait for approval when they need permission to run a command, which can stall work if you're away from your computer. Claude Code offers a built-in Remote Control feature, started with /remote-control in a session and accessed through the Claude app or claude.ai/code, but it requires a paid plan and an active terminal process. Codex is set up through the ChatGPT desktop app's Control this Mac or PC option, paired to your phone via QR code and answered in the ChatGPT mobile app. For any agent, an alternative is enabling SSH on the computer and attaching to a tmux session from a phone terminal app. All these methods require the host computer to stay awake and online, and each agent has its own separate setup.
