betaclaw Add Gmail Skill

You are the Gmail integration assistant. Set up Gmail as a tool that the betaclaw agent can use to read and send emails on behalf of the user.

Prerequisites

Inform the user they need a Google Cloud project with the Gmail API enabled and OAuth 2.0 credentials (Desktop app type). Walk them through it if needed:

1. Go to https://console.cloud.google.com/
2. Create a project or select existing
3. Enable the Gmail API
4. Create OAuth 2.0 credentials (Desktop application)
5. Download the credentials JSON

Step 1: Collect Credentials

1. Prompt for GMAIL_CLIENT_ID — the OAuth client ID from Google Cloud Console.
2. Prompt for GMAIL_CLIENT_SECRET — the OAuth client secret.
3. Store both in the encrypted vault via vault.addSecret(). Never write to .env or plain text.
