## What it does

The command hooks an Expo app into the Claude action bar. It first confirms the target root really is an Expo app, then creates or updates `script/build_and_run.sh` and `.codex/environments/environment.toml`.

One primary `Run` action always points at `./script/build_and_run.sh`. Extra actions such as `ios`, `android`, `web`, `dev-client`, `doctor` or `export-web` are added only when you list them comma-separated in the `actions` argument. Pass `root` if the app does not sit in the current directory.

Setup does not start the dev server. That happens only with `run=true` or when you ask for it directly. At the end the command validates with `bash -n ./script/build_and_run.sh` and `./script/build_and_run.sh --help`, then reports the script path, environment file path, action names and validation results. Point it at a non-Expo folder and the check stops you early, which is worth knowing before you run it on a monorepo root.

## Install

### Codex (native platform)

**Manually: put the files in place**
- File: `~/.codex/prompts/setup-codex-run-actions.md` — Call it with /prompts:setup-codex-run-actions. Codex marks this format deprecated in favour of skills

### Claude Code

**Manually: put the files in place**
- File: `.claude/commands/setup-codex-run-actions.md` — Call it with /setup-codex-run-actions. For all projects use ~/.claude/commands/

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/setup-codex-run-actions.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/setup-codex-run-actions.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/openai/plugins/tree/HEAD/plugins/expo/commands/setup-codex-run-actions.md

## When to use it
- add a run button for an Expo app to the Claude action bar
- set up iOS, Android and web buttons in one pass
- generate `script/build_and_run.sh` to build and launch the project
- write the Claude environment file at `.codex/environments/environment.toml`
- syntax-check the run script before using it

## Example prompts
- /setup-codex-run-actions
- /setup-codex-run-actions actions=ios,android,web
- /setup-codex-run-actions root=apps/mobile run=true

BEGIN THIRD-PARTY FILE 9328b3f0d6a6ee62
```text
# /setup-codex-run-actions

Wire the current Expo project into the Codex app action bar.

## Arguments

- `root`: Expo app root, if not the current directory (optional)
- `actions`: comma-separated extra buttons such as `ios,android,web,dev-client,doctor,export-web` (optional)
- `run`: whether to start the Expo dev server after setup (optional, default: false)

## Workflow

1. Use the `codex-expo-run-actions` skill.
2. Confirm the target root is an Expo app before editing.
3. Create or update `script/build_and_run.sh` using the skill reference.
4. Create or update `.codex/environments/environment.toml`.
5. Always wire one primary `Run` action to `./script/build_and_run.sh`.
6. Add optional actions only when requested.
7. Validate with `bash -n ./script/build_and_run.sh` and `./script/build_and_run.sh --help`.
8. Start the dev server only when `run=true` or the user explicitly asks.

## Output

Report the script path, environment file path, action names, and validation command results.
