Agent IDE — Codex fork for AI-native development environment
2fe4be1aa9
## Why `codex-rs/arg0` only needed two things from `codex-core`: - the `find_codex_home()` wrapper - the special argv flag used for the internal `apply_patch` self-invocation path That made `codex-arg0` depend on `codex-core` for a very small surface area. This change removes that dependency edge and moves the shared `apply_patch` invocation flag to a more natural boundary (`codex-apply-patch`) while keeping the contract explicitly documented. ## What Changed - Moved the internal `apply_patch` argv[1] flag constant out of `codex-core` and into `codex-apply-patch`. - Renamed the constant to `CODEX_CORE_APPLY_PATCH_ARG1` and documented that it is part of the Codex core process-invocation contract (even though it now lives in `codex-apply-patch`). - Updated `arg0`, the core apply-patch runtime, and the `codex-exec` apply-patch test to import the constant from `codex-apply-patch`. - Updated `codex-rs/arg0` to call `codex_utils_home_dir::find_codex_home()` directly instead of `codex_core::config::find_codex_home()`. - Removed the `codex-core` dependency from `codex-rs/arg0` and added the needed direct dependency on `codex-utils-home-dir`. - Added `codex-apply-patch` as a dev-dependency for `codex-rs/exec` tests (the apply-patch test now imports the moved constant directly). ## Verification - `cargo test -p codex-apply-patch` - `cargo test -p codex-arg0` - `cargo test -p codex-core --lib apply_patch` - `cargo test -p codex-exec test_standalone_exec_cli_can_use_apply_patch` - `cargo shear` |

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.
