## Why Several legacy `EventMsg` variants were still emitted or mapped even though clients either ignored them or had moved to item/lifecycle events. `Op::Undo` had also degraded to an unavailable shim, so this removes that dead task path instead of preserving a command that cannot do useful work. `McpStartupComplete`, `WebSearchBegin`, and `ImageGenerationBegin` are intentionally kept because useful consumers still depend on them: MCP startup completion drives readiness behavior, and the begin events let app-server/core consumers surface in-progress web-search and image-generation items before the final payload arrives. ## What Changed - Removed weak legacy event variants and payloads from `codex-protocol`, including legacy agent deltas, background events, and undo lifecycle events. - Kept/restored `EventMsg::McpStartupComplete`, `EventMsg::WebSearchBegin`, and `EventMsg::ImageGenerationBegin` with serializer and emission coverage. - Updated core, rollout, MCP server, app-server thread history, review/delegate filtering, and tests to rely on the useful replacement events that remain. - Removed `Op::Undo`, `UndoTask`, the undo test module, and stale TUI slash-command comments. - Stopped agent job/background progress and compaction retry notices from emitting `BackgroundEvent` payloads. ## Verification - `cargo check -p codex-protocol -p codex-app-server-protocol -p codex-core -p codex-rollout -p codex-rollout-trace -p codex-mcp-server` - `cargo test -p codex-protocol -p codex-app-server-protocol -p codex-rollout -p codex-rollout-trace -p codex-mcp-server` - `cargo test -p codex-core --test all suite::items` - `just fix -p codex-protocol -p codex-app-server-protocol -p codex-core -p codex-rollout -p codex-rollout-trace -p codex-mcp-server` - Earlier coverage on this PR also included `codex-mcp`, `codex-tui`, core library tests, MCP/plugin/delegate/review/agent job tests, and MCP startup TUI tests.

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.
