## Why Windows can reject plugin cache upgrades when a running MCP server still has its working directory inside the currently active plugin version. The existing cache refresh path replaces `plugins/cache/<marketplace>/<plugin>` as a whole, so a live handle under the old version can make an otherwise ordinary version bump fail. This PR keeps the existing plugin-selection model intact while making version bumps less disruptive. ## What changed - When installing a new version beside an existing plugin cache root, move only the staged version directory into place instead of replacing the whole plugin root. - Best-effort prune older sibling version directories after the new version is activated. - Preserve the existing whole-root replacement path for first installs and same-version refreshes. - Add regression coverage for upgrading from `1.0.0` to `2.0.0` without replacing the plugin root. ## Verification - `cargo test -p codex-core-plugins install_with_new_version` - `cargo fmt --package codex-core-plugins --check`
npm i -g @openai/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.
