## Summary - align the default multi-agent v2 root and subagent hints with the evaluated prompt guidance for direct collaboration-tool calls, parallel delegation, and shared workspaces - keep the current `interrupt_agent` tool name and existing concurrency-hint placement, with the explicit no-spawn instruction last - document the context tradeoff between `fork_turns="none"` and `fork_turns="all"` in the v2 `spawn_agent` description - extend the focused prompt and tool-surface tests ## Why The evaluated multi-agent prompt includes operational guidance that is missing from the current Codex defaults. This applies that guidance to the current tool surface without restoring stale `close_agent` or duplicated concurrency wording. ## User impact Multi-agent v2 receives clearer instructions about when and how to parallelize work, how agent workspaces interact, and how `fork_turns` affects subagent context. The existing default opt-out behavior remains in place. ## Testing - `just fmt` - `just test -p codex-core multi_agent_v2_default_usage_hints_use_configured_thread_cap` - `just test -p codex-core multi_agent_feature_selects_one_agent_tool_family`
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.
