## Why Guardian approvals now run as review sessions, but Codex analytics did not have a terminal event for those reviews. That made it hard to measure approval outcomes, failure modes, Guardian session reuse, model metadata, token usage, and timing separately from the parent turn. ## What changed Adds `codex_guardian_review` analytics emission for Guardian approval reviews. The event is emitted from the Guardian review path with review identity, target item id, approval request source, a PII-minimized reviewed-action shape, terminal decision/status, failure reason, Guardian assessment fields, Guardian session metadata, token usage, and timing metadata. The reviewed-action payload intentionally omits high-risk fields such as shell commands, working directories, argv, file paths, network targets/hosts, rationale, retry reason, and permission justifications. It also classifies prompt-build failures separately from Guardian session/runtime failures so fail-closed cases are distinguishable in analytics. ## Verification - Guardian review analytics tests cover terminal success, timeout/cancel/fail-closed paths, session metadata, and token usage plumbing. - `cargo clippy -p codex-core --lib --tests -- -D warnings` --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

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.
