# Set Up Spotify Portal

Set up the Portal CLI for every supported host.

## Critical rules

1. Never ask the user to paste access tokens, authorization codes, or other credentials into chat.
2. Run `--help` before relying on a Portal CLI or host command or flag.
3. Prefer `--json` whenever the agent consumes command output.
4. Never assume the default authenticated Portal instance when more than one instance is listed. Ask the user which instance to use.

## CLI invocation

Verify Node.js and npm:

```bash
node --version
npm --version
```

Run Portal CLI commands through the upstream package:

```bash
npx @spotify/portal-cli <command>
```

Inside a Portal source checkout, `npx` resolves the workspace-local build; elsewhere it fetches the published npm package.

## Setup workflow

Complete these steps in order.

### 1. Verify command discovery

```bash
npx @spotify/portal-cli --help
npx @spotify/portal-cli auth --help
```

The first command should list `auth`, `actions`, `owner`, `search`, and `service`. If they are absent, the resolved CLI build is too old for this workflow. Stop and report that a newer Portal CLI release is required.

### 2. Inspect existing instances

```bash
npx @spotify/portal-cli auth list
```

- Reuse an instance whose backend URL matches the user's target.
- If one instance exists and the user did not name a target, confirm it before continuing.
- If multiple instances exist, show their names and URLs and ask the user to choose.
- If no matching instance exists, obtain the Portal backend URL and a short instance name from the user.

### 3. Authenticate when needed

Run login only when the chosen instance is not already authenticated:

```bash
npx @spotify/portal-cli auth login --instance <instance-name> --backend-url <backend-url>
```

The command may open a browser. Let the user complete authentication there. If the environment cannot open a browser, inspect login help and use its no-browser flow. Never request credentials in chat.

### 4. Select and verify the instance

```bash
npx @spotify/portal-cli auth select --instance <instance-name>
npx @spotify/portal-cli auth show --instance <instance-name>
```

Do not continue unless `auth show` succeeds for the chosen instance.

### 5. Verify agent-safe CLI access

```bash
npx @spotify/portal-cli actions list --json
```

Success proves that the CLI can authenticate, reach the selected Portal instance, and read the user's available actions.

## Completion report

Report:

- CLI build source: workspace-local or published package
- selected instance name and backend URL
- CLI authentication: confirmed or blocked
- `actions list --json`: confirmed or blocked
