Gmail Context Provider
======================
GmailContextProvider gives agents read/write access to Gmail through
specialized sub-agents. The calling agent receives:
- ``query_gmail`` — search emails, read threads, list labels
- ``update_gmail`` — draft emails, send replies, manage labels (when write=True)
This example demonstrates:
1. Read-only mode: searching and summarizing emails
2. Read-write mode: drafting a follow-up based on email content
Compare with: 19_calendar.py for calendar operations
See also: 20_google_workspace.py for multi-provider workflows
Setup (OAuth - recommended for personal Gmail):
1. Create OAuth credentials in Google Cloud Console
- APIs & Services > Credentials > Create OAuth Client ID
- Application type: Desktop app
- Download the JSON or note the client ID and secret
2. Enable the Gmail API in your project
3. Set environment variables::
export GOOGLE_CLIENT_ID=your-client-id.apps.googleusercontent.com
export GOOGLE_CLIENT_SECRET=GOCSPX-...
export GOOGLE_PROJECT_ID=your-project-id
4. First run opens browser for consent, token cached to gmail_token.json
Setup (Service Account - for Google Workspace):
1. Create service account with domain-wide delegation
2. Grant Gmail scopes in Google Admin > Security > API Controls
3. Set environment variables::
export GOOGLE_SERVICE_ACCOUNT_FILE=/path/to/service-account.json
export GOOGLE_DELEGATED_USER=user@yourdomain.com
Requires: OPENAI_API_KEY + one of the auth methods above
