Claude Code vs Codex
Two terminal-native coding agents, two styles of autonomy. Which one actually ships working code on your repo?
AI coding agents have graduated from autocomplete to teammates that read a repo, edit files, run commands, and explain themselves. Claude Code and Codex are the two most capable terminal-native options — and they make different bets about how much rope to give the model.
The right pick depends on how much you want to supervise versus delegate.
