## Why Long-running turns can accumulate enough denied auto-review decisions to trip the global short-circuit even when those denials are spread far apart. The breaker should still stop genuinely bad loops, but it should judge recent behavior instead of lifetime turn history. ## What changed - Replaced the lifetime `10 total denials` threshold with `10 denials in the last 50 reviews`. - Kept the existing `3 consecutive denials` interrupt behavior unchanged. - Tracked recent auto-review outcomes in the circuit breaker and updated the warning copy to report the rolling-window count. - Renamed the new rolling-window coverage to `auto_review_*` test names. - Added coverage that confirms older denials fall out of the 50-review window and no longer trigger the breaker. ## Validation - `just fmt` - `cargo test -p codex-core guardian_rejection_circuit_breaker --lib` - `cargo test -p codex-core auto_review_rejection_circuit_breaker --lib`

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.
