## Why `codex-otel` still carried `disable-default-metrics-exporter`, which was the last remaining workspace crate feature. We are removing workspace crate features because they do not fit our current build model well: - our Bazel setup does not honor crate features today, which can let feature-gated issues go unnoticed - they create extra crate build permutations that we want to avoid For this case, the feature was only being used to keep the built-in Statsig metrics exporter off in test and debug-oriented contexts. This repo already treats `debug_assertions` as the practical proxy for that class of behavior, so OTEL should follow the same convention instead of keeping a dedicated crate feature alive. ## What changed - removed `disable-default-metrics-exporter` from `codex-rs/otel/Cargo.toml` - removed the `codex-otel` dev-dependency feature activation from `codex-rs/core/Cargo.toml` - changed `codex-rs/otel/src/config.rs` so the built-in `OtelExporter::Statsig` default resolves to `None` when `debug_assertions` is enabled, with a focused unit test covering that behavior - removed the final feature exceptions from `.github/scripts/verify_cargo_workspace_manifests.py`, so workspace crate features are now hard-banned instead of temporarily allowlisted - expanded the verifier error message to explain the Bazel mismatch and build-permutation cost behind that policy ## How tested - `python3 .github/scripts/verify_cargo_workspace_manifests.py` - `cargo test -p codex-otel` - `cargo test -p codex-core metrics_exporter_defaults_to_statsig_when_missing` - `cargo test -p codex-app-server app_server_default_analytics_` - `just bazel-lock-check`
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.
