## Summary This updates the embedded `imagegen` system skill in `codex-rs/skills` with the ImageGen 2 skill changes from `openai/skills-internal#87`. The bundled skill now keeps normal image generation/editing on the built-in `image_gen` path, updates the CLI fallback defaults to `gpt-image-2`, and routes explicit transparent-output requests through `gpt-image-1.5` with clear guidance that `gpt-image-2` does not support transparent backgrounds. ## Details - Update `SKILL.md` routing guidance for built-in vs CLI fallback behavior. - Update CLI/API references for `gpt-image-2` size constraints, quality options, near-4K sizes, and unsupported options. - Update `scripts/image_gen.py` defaults and validation: - default model `gpt-image-2` - default size `auto` - default quality `medium` - reject transparent backgrounds on `gpt-image-2` - reject `input_fidelity` on `gpt-image-2` - validate flexible `gpt-image-2` sizes and suggest `3824x2160` / `2160x3824` for near-4K requests - Update prompt/reference docs with the new model and routing guidance. ## Validation - `cargo test -p codex-skills` - `git diff --check` - Manual CLI dry-runs for: - default `gpt-image-2` payload - `3824x2160` near-4K size acceptance - `3840x2160` rejection with near-4K guidance - transparent background rejection on `gpt-image-2` - transparent background acceptance on `gpt-image-1.5` - `input_fidelity` rejection on `gpt-image-2` Bazel target check was not run locally because `bazel` is not installed in this environment.

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.
