## Why `MultiAgentV2` follow-up messages are delivered to agents as assistant-authored `InterAgentCommunication` envelopes. When `followup_task` used `interrupt: true`, the interrupted-turn guidance was still persisted as a contextual user message, so model-visible history made a system-generated interruption boundary look user-authored. This keeps interruption guidance consistent with the rest of the v2 inter-agent message stream while preserving the legacy marker shape for non-v2 sessions. ## What changed - Make `interrupted_turn_history_marker` feature-aware. - Record the interrupted-turn marker as an assistant `OutputText` message when `Feature::MultiAgentV2` is enabled. - Keep the existing user contextual fragment for non-v2 sessions. - Apply the same feature-aware marker to interrupted fork snapshots. - Add coverage for the live `followup_task` interrupt path and the helper-level v2 marker shape. ## Testing - `cargo test -p codex-core multi_agent_v2_followup_task_interrupts_busy_child_without_losing_message -- --nocapture` - `cargo test -p codex-core multi_agent_v2_interrupted_marker_uses_assistant_output_message -- --nocapture` - `cargo test -p codex-core interrupted_fork_snapshot -- --nocapture`
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.
