## Summary - run apply_patch through the executor filesystem when a remote environment is present instead of shelling out to the local process - thread the executor FileSystem into apply_patch interception and keep existing local behavior for non-remote turns - make the apply_patch integration harness use the executor filesystem for setup/assertions - add remote-aware skips for turn-diff coverage that still reads the test-runner filesystem ## Why Remote apply_patch needed to mutate the remote workspace instead of the local checkout. The tests also needed to seed and assert workspace state through the same filesystem abstraction so local and remote runs exercise the same behavior. ## Validation - `just fmt` - `git diff --check` - `cargo check -p core_test_support --tests` - `cargo test -p codex-core --test all suite::shell_serialization::apply_patch_custom_tool_call -- --nocapture` - `cargo test -p codex-core --test all suite::apply_patch_cli::apply_patch_cli_updates_file_appends_trailing_newline -- --nocapture` - remote `cargo test -p codex-core --test all apply_patch_cli -- --nocapture` (229 passed)

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.
