## Why We need `PermissionRequest` hook support! Also addresses: - https://github.com/openai/codex/issues/16301 - run a script on Hook to do things like play a sound to draw attention but actually no-op so user can still approve - can omit the `decision` object from output or just have the script exit 0 and print nothing - https://github.com/openai/codex/issues/15311 - let the script approve/deny on its own - external UI what will run on Hook and relay decision back to codex ## Reviewer Note There's a lot of plumbing for the new hook, key files to review are: - New hook added in `codex-rs/hooks/src/events/permission_request.rs` - Wiring for network approvals `codex-rs/core/src/tools/network_approval.rs` - Wiring for tool orchestrator `codex-rs/core/src/tools/orchestrator.rs` - Wiring for execve `codex-rs/core/src/tools/runtimes/shell/unix_escalation.rs` ## What - Wires shell, unified exec, and network approval prompts into the `PermissionRequest` hook flow. - Lets hooks allow or deny approval prompts; quiet or invalid hooks fall back to the normal approval path. - Uses `tool_input.description` for user-facing context when it helps: - shell / `exec_command`: the request justification, when present - network approvals: `network-access <domain>` - Uses `tool_name: Bash` for shell, unified exec, and network approval permission-request hooks. - For network approvals, passes the originating command in `tool_input.command` when there is a single owning call; otherwise falls back to the synthetic `network-access ...` command. <details> <summary>Example `PermissionRequest` hook input for a shell approval</summary> ```json { "session_id": "<session-id>", "turn_id": "<turn-id>", "transcript_path": "/path/to/transcript.jsonl", "cwd": "/path/to/cwd", "hook_event_name": "PermissionRequest", "model": "gpt-5", "permission_mode": "default", "tool_name": "Bash", "tool_input": { "command": "rm -f /tmp/example" } } ``` </details> <details> <summary>Example `PermissionRequest` hook input for an escalated `exec_command` request</summary> ```json { "session_id": "<session-id>", "turn_id": "<turn-id>", "transcript_path": "/path/to/transcript.jsonl", "cwd": "/path/to/cwd", "hook_event_name": "PermissionRequest", "model": "gpt-5", "permission_mode": "default", "tool_name": "Bash", "tool_input": { "command": "cp /tmp/source.json /Users/alice/export/source.json", "description": "Need to copy a generated file outside the workspace" } } ``` </details> <details> <summary>Example `PermissionRequest` hook input for a network approval</summary> ```json { "session_id": "<session-id>", "turn_id": "<turn-id>", "transcript_path": "/path/to/transcript.jsonl", "cwd": "/path/to/cwd", "hook_event_name": "PermissionRequest", "model": "gpt-5", "permission_mode": "default", "tool_name": "Bash", "tool_input": { "command": "curl http://codex-network-test.invalid", "description": "network-access http://codex-network-test.invalid" } } ``` </details> ## Follow-ups - Implement the `PermissionRequest` semantics for `updatedInput`, `updatedPermissions`, `interrupt`, and suggestions / `permission_suggestions` - Add `PermissionRequest` support for the `request_permissions` tool path --------- Co-authored-by: Codex <noreply@openai.com>
npm i -g @openai/codex
or brew install --cask codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
