## Summary Renames the MultiAgentV2 turn-triggering tool from `assign_task` to `followup_task` so the exposed tool name better describes sending an additional task to an existing agent. This updates the tool spec, handler/module names, registry wiring, default multi-agent v2 usage hints, and tests. Rollout trace classification keeps accepting legacy `assign_task` events so older traces still reduce correctly, while docs show the new tool name. ## Test plan - `just test -p codex-core followup_task` - `just test -p codex-core -E 'test(multi_agent_feature_selects_one_agent_tool_family) | test(multi_agent_v2_can_use_configured_tool_namespace) | test(code_mode_only_can_expose_namespaced_multi_agent_v2_as_normal_tools)'` - `just test -p codex-rollout-trace` - `just fix -p codex-core` - `just fix -p codex-rollout-trace` Notes: `just fmt` ran `cargo fmt` but failed in the Python ruff phase because the local environment could not resolve `hatchling>=1.27.0` from the configured internal registry. A full `just test -p codex-core` also hit unrelated environment-sensitive integration failures involving missing spawned test binaries/sandbox behavior; the changed multi-agent spec/handler tests passed in the filtered runs above.
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.
