Codex CLI hooks are now stable — new PermissionRequest hook added (6 total)

Exciting Update: Codex CLI Hooks Achieve Stability with New PermissionRequest Hook and Expanded Functionality

The development team is pleased to announce the official stabilization of the Codex CLI hooks, an important milestone that enhances both reliability and extensibility for users and developers alike. Alongside this stability, a new hook—PermissionRequest—has been introduced, expanding the CLI’s capabilities and offering further customization options.

Overview of the Updated Hook System

The Codex CLI now features a total of six carefully designed hooks, each serving a specific role in the user interaction and process flow:

1. SessionStart
   Triggered at the beginning of a session, allowing for initialization routines or preparatory actions.

2. UserPromptSubmit
   Activated upon user prompt submission, enabling custom handling or logging of user input.

3. PreToolUse
   Invoked prior to executing a tool, offering a chance to modify parameters or perform validation.

4. PermissionRequest (New)
   A newly added hook providing an opportunity to handle permission requests dynamically, enhancing control over resource access and security.

5. PostToolUse
   Triggered after a tool has completed execution, suitable for cleanup, logging, or post-processing.

6. Stop
   Marks the end of the CLI process, allowing for finalization tasks or cleanup routines.

Enhancing User Experience with Custom Hooks

To complement these hooks, I maintain a dedicated drop-in hooks package that enriches user interaction by playing a sound on every event. This feature ensures users stay informed of ongoing processes, regardless of their platform, with fully cross-platform support including Windows, Mac, and Linux installers.
