Use this example configuration as a starting point. It includes most keys Codex reads from config.toml, along with default behaviors, recommended values where helpful, and short notes.

For explanations and guidance, see:

• Config basics
• Advanced Config
• Config Reference
• Sandbox and approvals
• Managed configuration

Use the snippet below as a reference. Copy only the keys and sections you need into ~/.codex/config.toml (or into a project-scoped .codex/config.toml), then adjust values for your setup.
