## Why Native Codex currently teaches multi-agent concurrency through the `spawn_agent` tool description, while bridge-driven evals frame the same limit as a shared pool of active agent slots. That mismatch makes the model-facing story harder to reason about, especially because the tool-level wording does not make it explicit that the limit covers the whole agent team, including the current agent. This change gives native Codex the same mental model: tell the root agent and subagents how many active slots exist, and remove the separate `spawn_agent` limit wording. ## What changed - Extend the built-in `multi_agent_v2` root and subagent usage hints with shared-slot guidance derived from the resolved `max_concurrent_threads_per_session` value. - Keep the complete default hints in `MultiAgentV2Config` so initial context and forked histories consume the same canonical strings. - Drop the redundant `spawn_agent` description text and remove the now-unused limit plumbing from the tool spec path. ## Testing - `just test -p codex-core usage_hint` - `just test -p codex-core multi_agent_v2_default_session_thread_cap_counts_root` - `just test -p codex-core multi_agent_v2_default_usage_hints_use_configured_thread_cap` - `just test -p codex-core spawn_agent_tool_v2_requires_task_name_and_lists_visible_models` - `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.
