## Summary - hide deferred MCP/app nested tool descriptions from the `exec` prompt in code mode - add short guidance that omitted nested tools are still available through `ALL_TOOLS` - cover the code_mode_only path with an integration test that discovers and calls a deferred app tool ## Motivation `code_mode_only` exposes only top-level `exec`/`wait`, but the `exec` description could still include a large nested-tool reference. This keeps deferred nested tools callable while avoiding that prompt bloat. ## Tests - `just fmt` - `just fix -p codex-code-mode` - `just fix -p codex-tools` - `cargo test -p codex-code-mode exec_description_mentions_deferred_nested_tools_when_available` - `cargo test -p codex-tools create_code_mode_tool_matches_expected_spec` - `cargo test -p codex-core code_mode_only_guides_all_tools_search_and_calls_deferred_app_tools`

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.
