Fixes #24249. ## Why Codex already supports discovering marketplaces under both `.agents/plugins/marketplace.json` and `.claude-plugin/marketplace.json`. The Git marketplace auto-upgrade no-op check only looked for the `.agents` layout. That meant an installed `.claude-plugin` marketplace with matching revision metadata still looked absent, so plugin list/startup upgrade work could stage and re-activate the same marketplace again. That matches the failure shape in #24249: the report called out repeated marketplace sync/cache refresh logs and a large recently-touched `.tmp/marketplaces/.staging` directory. This change makes the auto-upgrade path recognize the installed `.claude-plugin` marketplace as already current, which should remove that staging/activation feedback loop. ## What changed `codex-rs/core-plugins/src/marketplace_upgrade.rs` now uses the existing supported marketplace manifest discovery helper when deciding whether an installed Git marketplace is already current. Existing local plugin source validation is unchanged; `source: "./"` still remains invalid. ## Confidence Confidence is high that this fixes the repeated marketplace upgrade path: the old hardcoded layout check was definitely wrong for installed `.claude-plugin` marketplaces, and the reported staging churn points directly at that path. Confidence is not 100% because we do not have a CPU profile or a fully re-run reporter repro. A malformed marketplace entry can still be logged as invalid if another caller repeatedly lists plugins; this PR fixes the staging/upgrade feedback loop that likely made the failure pathological, not every possible source of repeated marketplace resolution.
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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
