## Why Permission approval responses must not be able to grant more access than the tool requested. Moving this flow to `PermissionProfile` means the comparison must be profile-shaped instead of `SandboxPolicy`-shaped, and cwd-relative special paths such as `:cwd` and `:project_roots` must stay anchored to the turn that produced the request. ## What changed This implements semantic `PermissionProfile` intersection in `codex-sandboxing` for file-system and network permissions. The intersection accepts narrower path grants, rejects broader grants, preserves deny-read carve-outs and glob scan depth, and materializes cwd-dependent special-path grants to absolute paths before they can be recorded for reuse. The request-permissions response paths now use that intersection consistently. App-server captures the request turn cwd before waiting for the client response, includes that cwd in the v2 approval params, and core stores the requested profile plus cwd for direct TUI/client responses and Guardian decisions before recording turn- or session-scoped grants. The TUI app-server bridge now preserves the app-server request cwd when converting permission approval params into core events. ## Verification - `cargo test -p codex-sandboxing intersect_permission_profiles -- --nocapture` - `cargo test -p codex-app-server request_permissions_response -- --nocapture` - `cargo test -p codex-core request_permissions_response_materializes_session_cwd_grants_before_recording -- --nocapture` - `cargo check -p codex-tui --tests` - `cargo check --tests` - `cargo test -p codex-tui app_server_request_permissions_preserves_file_system_permissions`

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.
