## Why `agents.max_depth` is a legacy multi-agent v1 guard. Multi-agent v2 uses task-path routing and its own session/thread limits, so v2 should not reject nested `spawn_agent` calls just because the thread-spawn depth has reached the v1 maximum. Keeping the v1 depth guard active in v2 prevents deeper task trees even though the v2 path still needs the depth value only for lineage and task-path metadata. ## What Changed - Removed the depth-limit rejection from the multi-agent v2 `spawn_agent` handler while still computing child depth for lineage/path metadata. - Made the depth-based disabling of legacy `SpawnCsv`/`Collab` tools apply only when `Feature::MultiAgentV2` is disabled. - Added `multi_agent_v2_spawn_agent_ignores_configured_max_depth` to cover a v2 child spawning another agent when `agent_max_depth = 1`, while the existing v1 depth-limit tests continue to enforce the legacy behavior. ## Verification - `cargo test -p codex-core multi_agent_v2_spawn_agent_ignores_configured_max_depth -- --nocapture` - `cargo test -p codex-core depth_limit -- --nocapture` - `cargo test -p codex-core tools::handlers::multi_agents::tests -- --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.
