## Why Remote compaction v2 consumes a normal Responses stream, but that compaction-specific stream consumer dropped the `response.completed` id. As a result, the `responses_websocket_response_processed` lifecycle notification was emitted for normal turn sampling but not after a v2 remote compaction response was fully processed. ## What changed - Return the completed response id alongside the v2 `context_compaction` output item. - After v2 compacted history is installed, send `response.processed` through the same websocket session when the feature is enabled. - Add websocket regression coverage for a remote compaction v2 request followed by `response.processed`. ## Verification - `cargo test -p codex-core --test all responses_websocket_sends_response_processed_after_remote_compaction_v2 -- --nocapture` - `cargo test -p codex-core collect_context_compaction_output_accepts_additional_output_items -- --nocapture`

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.
