Inspired by Theo's original post on X.
The basic idea: if you prefer Claude Code's agent harness and terminal UX to the Codex CLI, claudex lets you keep Claude Code's interface, tools, permissions, plugins, and workflow while using GPT/Codex models underneath. A local CLIProxyAPI server translates and routes Claude Code's requests to a model available through Codex OAuth.
The important isolation rule is:
claudecontinues to work normally with its existing account and configuration.codexcontinues to work normally with its existing configuration.
