### Motivation - Prevent untrusted js_repl code from supplying arbitrary external URLs that the host would forward into model input and cause external fetches / data exfiltration. This change narrows the emitImage contract to safe, self-contained data URLs. ### Description - Kernel: added `normalizeEmitImageUrl` and enforce that string-valued `codex.emitImage(...)` inputs and `input_image`/content-item paths only accept non-empty `data:` URLs; byte-based paths still produce data URLs as before (`kernel.js`). - Host: added `validate_emitted_image_url` and check `EmitImage` requests before creating `FunctionCallOutputContentItem::InputImage`, returning an error to the kernel if the URL is not a `data:` URL (`mod.rs`). - Tests/docs: added a runtime test `js_repl_emit_image_rejects_non_data_url` to assert rejection of non-data URLs and updated user-facing docs/instruction text to state `data URL` support instead of generic direct image URLs (`mod.rs`, `docs/js_repl.md`, `project_doc.rs`). ### Testing - Ran `just fmt` in `codex-rs`; it completed successfully. - Added a runtime test (`cargo test -p codex-core js_repl_emit_image_rejects_non_data_url`) but executing the test in this environment failed due to a missing system dependency required by `codex-linux-sandbox` (the vendored `bubblewrap` build requires `libcap.pc` via `pkg-config`), so the test could not be run here. - Attempted a focused `cargo test` invocation with and without default features; both compile/test attempts were blocked by the same missing system `libcap` dependency in this environment. ------ [Codex Task](https://chatgpt.com/codex/tasks/task_i_69a7837bce98832d91db92d5f76d6cbe)

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.
