## Why `codex-cloud-tasks-client` was mixing two different roles: the real HTTP client and the mock implementation used by tests and local mock mode. Keeping both in the same crate forced Cargo feature toggles and Bazel `crate_features` just to pick an implementation. This change keeps `codex-cloud-tasks-client` focused on the shared API surface and real backend client, and moves the mock implementation into its own crate so we can remove those feature permutations cleanly. ## What changed - add a new `codex-cloud-tasks-mock-client` crate that owns `MockClient` - remove the `mock` and `online` features from `codex-cloud-tasks-client` - make `codex-cloud-tasks-client` unconditionally depend on `codex-backend-client` and export `HttpClient` directly - gate the mock-mode path in `codex-cloud-tasks` behind `#[cfg(debug_assertions)]`, so release builds always initialize the real HTTP client - update `codex-cloud-tasks` and its tests to use `codex-cloud-tasks-mock-client::MockClient` wherever mock behavior is needed - remove the matching Bazel `crate_features` override and shrink the manifest verifier allowlist accordingly ## How tested - `cargo test -p codex-cloud-tasks-client` - `cargo test -p codex-cloud-tasks-mock-client` - `cargo test -p codex-cloud-tasks` --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

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.
