Setup

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:

node --version
npm --version

Run Portal CLI commands through the upstream package:

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

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

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:

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

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

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
