Codex Advanced Configuration ​

中文 | English

Summary ​

This source expands the Codex control plane beyond the basics: profiles, one-off CLI overrides, project config discovery, hooks, provider definitions, runtime telemetry, notifications, and UI behavior are all configurable parts of the local client.

Source ​

Key Contributions ​

  • Introduces named profiles and clarifies how they override top-level defaults.
  • Documents --config as a TOML-parsed escape hatch for single-run overrides.
  • Explains project-root discovery, project-scoped .codex/config.toml loading, and hook activation.
  • Shows that model providers, observability, notifications, history persistence, and TUI controls all live inside the same configuration system.

Strongest Claims ​

  • Advanced configuration is about operating policy, not just model selection.
  • Project config discovery and project-root markers shape which docs, agents, and config layers Codex even sees.
  • Telemetry, notifications, and history settings are part of reliability work because they determine what evidence long-running sessions preserve.
