## Summary - split the single PR-blocking Bazel Windows test leg into four Windows shard jobs - preserve the existing required Windows Bazel check name with a lightweight aggregate gate - keep Linux/macOS Bazel test jobs and the separate Windows clippy/release jobs unchanged ## Why The ordinary PR Windows Bazel test leg was one GitHub Actions job, so Bazel only had in-job parallelism. This gives that lane real job-level fanout across separate Windows hosts while keeping the target set disjoint via stable label hashing. ## Evidence - final pre-rebase green run: `25774733562` - Windows shard target counts: `61/212`, `48/212`, `52/212`, `51/212` - Windows test fanout completed in about 7m29s versus a recent monolithic median around 22m26s ## Notes - this is scoped to the Bazel Windows test leg only - each shard keeps the existing Windows cross-compile/RBE path and restores the former monolithic Windows test cache - shard jobs do not upload duplicate repository caches after test work, keeping cache cleanup off the PR-blocking shard path - no local validation run; relying on GitHub Actions for the workflow-shaped check Co-authored-by: Codex <noreply@openai.com>
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.
