## Stack 1. This PR adds MITM hook config and model only. 2. Runtime follow up: #20659 wires hook enforcement into the proxy request path. 3. User facing config follow up: #18240 moves MITM policy into the PermissionProfile network tree. ## Why 1. Viyat asked for the original parent PR to be split so reviewers can inspect the policy model before request behavior changes. 2. This PR gives the proxy a typed MITM hook model, validation, matcher compilation, permissions TOML plumbing, schema support, and config tests. 3. This PR deliberately does not change CONNECT or MITM request handling. 4. Keeping runtime behavior out of this PR makes the review boundary simple: does the policy model parse, validate, compile, and lower correctly. ## Summary 1. Add the MITM hook config model and matcher compilation. 2. Validate hosts, methods, paths, query matchers, header matchers, secret sources, and reserved body matching. 3. Add wildcard matcher support for path, query value, and header value matching. 4. Add permissions TOML and schema support for flat runtime hook config. 5. Add config loader tests for MITM hook overlay behavior. ## Validation 1. Regenerated the config schema. 2. Ran the network proxy MITM hook unit tests. 3. Ran the core permission profile MITM hook parsing tests. 4. Ran the core config schema fixture test. 5. Ran the scoped Clippy fixer for the network proxy crate. 6. Ran the scoped Clippy fixer for the core crate. ## Notes 1. Runtime enforcement moved to #20659. 2. User facing PermissionProfile TOML shape remains in #18240.
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.
