## Why This is effectively a follow-up to [#15812](https://github.com/openai/codex/pull/15812). That change removed the special skill-script exec path, but `skill_metadata` was still being threaded through command-approval payloads even though the approval flow no longer uses it to render prompts or resolve decisions. Keeping it around added extra protocol, schema, and client surface area without changing behavior. Removing it keeps the command-approval contract smaller and avoids carrying a dead field through app-server, TUI, and MCP boundaries. ## What changed - removed `ExecApprovalRequestSkillMetadata` and the corresponding `skillMetadata` field from core approval events and the v2 app-server protocol - removed the generated JSON and TypeScript schema output for that field - updated app-server, MCP server, TUI, and TUI app-server approval plumbing to stop forwarding the field - cleaned up tests that previously constructed or asserted `skillMetadata` ## Testing - `cargo test -p codex-app-server-protocol` - `cargo test -p codex-protocol` - `cargo test -p codex-app-server-test-client` - `cargo test -p codex-mcp-server` - `just argument-comment-lint`
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.
