Gmail Search Skill

Search and fetch emails via Gmail API with flexible query options and output formats.

Prerequisites

Credentials must be configured in ~/.gmail_credentials/. Run setup to check status:

python3 scripts/gmail_search.py setup

Obtaining Gmail API Credentials

1. Create Google Cloud Project

1. Go to console.cloud.google.com
2. Click project dropdown -> "New Project"
3. Name it (e.g., "Gmail Agent Skill") -> Create

2. Enable Gmail API

1. Navigate to "APIs & Services" -> "Library"
2. Search for "Gmail API"
3. Click it and press "Enable"

3. Configure OAuth Consent Screen

1. Go to "OAuth consent screen" (left sidebar)
2. Choose "External" user type
3. Fill in required fields:
   • App name: Gmail Agent Skill
   • User support email: your email
   • Developer email: your email
4. Click "Save and Continue", skip Scopes
5. On "Test users" page, add your Gmail address
6. Complete all steps

4. Publish the Test App

Important: Without this step, you'll get "Error 403: access_denied".

1. Go back to "OAuth consent screen"
2. Under "Publishing status", click "Publish App"
3. Confirm the dialog

This keeps the app in test mode (not production) but allows your test users to authenticate. You'll see an "unverified app" warning during login - click "Advanced" -> "Go to Gmail Agent Skill (unsafe)" to proceed.

Note: Test tokens expire after 7 days. Production requires Google verification.

5. Create OAuth Credentials

1. Go to "Credentials" (left sidebar)
2. Click "Create Credentials" -> "OAuth client ID"
3. Select "Desktop app" as application type
4. Name it (e.g., "Gmail Agent Client")
5. Click "Create"

6. Get Your Credentials

1. Client ID will be displayed - copy it
2. Client Secret: Click the download icon or view details to get the secret

7. Save Credentials

Create ~/.gmail_credentials/credentials.json:

{
  "installed": {
    "client_id": "YOUR_CLIENT_ID",
    "client_secret": "YOUR_CLIENT_SECRET",
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://oauth2.googleapis.com/token",
    "redirect_uris": ["http://localhost"]
  }
}

8. Authenticate

python3 scripts/gmail_search.py auth

This opens a browser. Click through the "unverified app" warning ("Advanced" -> "Go to Gmail Agent Skill"), approve access, and you're ready.
