# cancorteaw-app

Local **Expo / React Native** app builder runner for my OpenClaw server.

This skill is a **controlled runner** that only executes an allowlisted script:

`/home/patron/apps/_bin/appctl`

and that script is restricted to operate under:

`/home/patron/apps/<project>`.

What it does

This skill wraps `appctl` to provide a safe, repeatable workflow:

  • **Create** a new Expo app scaffold under `/home/patron/apps/<name>`
  • **Add a screen** file under `/home/patron/apps/<name>/app/<Screen>.tsx`
  • **Start a web preview** (`expo start --web`) bound to `127.0.0.1` on a chosen port
  • **Check status** of the preview process
  • Commands

    1) Create a new app

    **Command:**

  • `new <name>`
  • **Example:**

  • `new demoapp`
  • **Result:**

  • Creates `/home/patron/apps/demoapp`
  • Initializes git (best-effort)
  • Uses `npx create-expo-app` in non-interactive mode
  • ---

    2) Add a screen

    **Command:**

  • `add-screen <name> <screenName> <title>`
  • **Example:**

  • `add-screen demoapp Settings "Settings"`
  • **Result:**

  • Writes: `/home/patron/apps/demoapp/app/Settings.tsx`
  • Makes a git commit (best-effort)
  • ---

    3) Start web preview

    **Command:**

  • `preview <name>`
  • **Environment:**

  • `EXPO_PORT` (optional): override preview port
  • Default: `19006`

    **Example:**

  • `preview demoapp`
  • `EXPO_PORT=19010 preview demoapp`
  • **Result:**

  • Starts `npx expo start --web --port <port>`
  • Writes logs to: `/home/patron/apps/_logs/<name>.preview.log`
  • Writes pid to: `/home/patron/apps/_state/<name>.pid`
  • Writes port to: `/home/patron/apps/_state/<name>.port`
  • ---

    4) Status

    **Command:**

  • `status <name>`
  • **Example:**

  • `status demoapp`
  • **Result:**

  • Prints RUNNING with URL if process is alive
  • Otherwise prints STOPPED
  • Safety / Guardrails

  • The runner is **allowlisted**: only `node`, `npm`, `npx`, `git`, `bash`, `python3` can be invoked.
  • All project paths are constrained to `/home/patron/apps`.
  • Preview binds to `127.0.0.1` (loopback). Expose it externally only via explicit SSH tunnel if desired.
  • Telemetry is disabled for Expo in preview (`EXPO_NO_TELEMETRY=1`).
  • Troubleshooting

  • If `preview` says running but page doesn’t load: check the log file in `/home/patron/apps/_logs/`.
  • If a port is busy: set `EXPO_PORT` to a free port and re-run `preview`.
  • To stop preview: `kill $(cat /home/patron/apps/_state/<name>.pid)` (if pid exists).
