## Summary - Preserve raw plugin skill-root snapshots in the matching loaded-plugin cache entry, keyed by the effective plugin root identity including namespace. - Pass those snapshots through `SkillsLoadInput` as an optional preload, so session startup reuses plugin parsing while ordinary skill loads pass `None`. - Keep plugin skill loading cohesive: the existing loaders accept the optional snapshots directly, and uncached or marketplace-detail paths do not create a cache. ## Why Plugin discovery already parses plugin skills to determine available capabilities. Cold session startup then scanned and parsed the same roots again while building the skills snapshot. This solves the same duplicate-work problem as #28623 while keeping ownership narrow: `PluginsManager` creates and owns `PluginSkillSnapshots` only for its loaded-plugin cache entry; `SkillsService` consumes an optional clone. Entry replacement or clearing naturally drops the snapshots, with no separate generation, capacity policy, or watcher coupling. ## Validation - `cargo clippy -p codex-core-skills --all-targets -- -D warnings` - `just test -p codex-core-plugins skills_service_reuses_skills_parsed_during_plugin_load` - `just test -p codex-core-skills namespaces_plugin_skills_using_provided_namespace` - `just fmt`
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.
