## Summary PR 3 of 5 in the cloud-managed config client stack. Adds enterprise-managed cloud config as a first-class config layer source. The layer metadata is preserved through config loading, diagnostics, debug output, hook attribution, and app-server protocol surfaces. ## Details - Enterprise-managed config becomes a normal config layer source with backend-supplied `id` and display `name` attached for provenance. - These layers are designed to behave like non-file managed config: they can surface syntax/type diagnostics by layer name even though there is no physical config file. - Relative path settings are resolved from a stored config base so cloud-delivered config remains consistent with existing MDM-delivered config semantics. - Hook attribution distinguishes config-delivered hooks from requirements-delivered hooks via `HookSource::CloudManagedConfig`. - This remains pull-based and snapshot-oriented; the PR adds layer identity/diagnostics, not dynamic reload behavior. ## Validation Validated through the targeted stack checks after rebasing onto current `main`: - Rust crate tests for config/hooks/cloud-config/backend-client/app-server-protocol - Filtered `codex-core` and `codex-app-server` `cloud_config_bundle` tests - Python generated-file contract test - `cargo shear --deny-warnings` - Targeted `argument-comment-lint` for config/hooks
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.
