## Why `code_mode_only` filters code-mode nested tools out of the top-level tool list. For multi-agent v2, we need a rollout shape where the collaboration tools remain callable as normal model tools without also being embedded into the code-mode `exec` tool declaration. Related to this: https://openai-corpws.slack.com/archives/C0AQLHB4U75/p1778660267922549 ## What Changed - Adds `features.multi_agent_v2.non_code_mode_only`, including config resolution, profile override handling, and generated schema coverage. - Introduces `ToolExposure::DirectModelOnly` so a tool can be included in the initial model-visible list while staying out of the nested code-mode tool surface. - Applies that exposure to the multi-agent v2 tools when the new flag is set: `spawn_agent`, `send_message`, `followup_task`, `wait_agent`, `close_agent`, and `list_agents`. - Updates code-mode-only filtering so direct-model-only tools remain visible while ordinary nested code-mode tools are still hidden. ## Verification - Added config parsing/profile tests for `non_code_mode_only`. - Added tool spec coverage for the code-mode-only multi-agent v2 exposure behavior.
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.
