## Stack 1. Parent PR: #18868 adds MITM hook config and model only. 2. This PR wires runtime enforcement. 3. User facing config follow up: #18240 moves MITM policy into the PermissionProfile network tree. ## Why 1. After the hook model exists, the proxy needs a separate behavior change that can be tested at the request path. 2. This PR makes hooked HTTPS hosts require MITM, evaluates inner requests after CONNECT, mutates headers for matching hooks, and blocks hooked hosts when no hook matches. 3. It also fixes the activation path so a permission profile with MITM hook policy starts the managed proxy. 4. Keeping this separate from #18868 lets reviewers focus on runtime effects, telemetry, and request mutation. ## Summary 1. Store compiled MITM hooks in network proxy state. 2. Require MITM for hooked hosts even when network mode is full. 3. Evaluate inner HTTPS requests against host specific hooks. 4. Apply hook actions by replacing request headers before forwarding. 5. Block hooked hosts when no hook matches and record block telemetry. 6. Treat profile MITM hook policy as managed proxy policy so the proxy starts when needed. 7. Keep the duplicate authorization header replacement and query preserving request rebuild in this runtime PR. 8. Add runtime tests and README guidance for hook enforcement. ## Validation 1. Ran the network proxy MITM policy tests. 2. Ran the hooked host CONNECT test. 3. Ran the authorization header replacement test. 4. Ran the core permission profile proxy activation test for MITM hooks. 5. Ran the scoped Clippy fixer for the network proxy crate. 6. Ran the scoped Clippy fixer for the core crate.
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.
