Purpose

Automate Gmail operations including reading, sending, replying, forwarding, and managing emails. Useful for email automation, inbox management, and communication workflows.

Gmail

Read, send, and manage Gmail via OAuth authentication.

CRITICAL SAFETY RULES

These rules are MANDATORY and must NEVER be bypassed:

1. NEVER Send Without Explicit Approval

• ALWAYS show the user the complete email (to, subject, body) before sending
• ALWAYS ask for explicit confirmation: "Do you want me to send this email? (yes/no)"
• NEVER auto-send emails, even if user says "send an email to X"
• NEVER send multiple emails in a loop without per-email confirmation

2. Draft-First Workflow (DEFAULT BEHAVIOR)

• ALL send/reply/forward operations create a draft FIRST
• User sees the draft and chooses: yes (send now), no (delete draft), or keep-draft (review in Gmail)
• This ensures user can ALWAYS review in Gmail UI before any email is sent

3. Sensitive Operations Require Confirmation

4. Read Operations Are Safe

These do NOT require confirmation:

• List emails, Search emails, Read email content
• List labels, List drafts, Get attachment

Pre-Flight Check (ALWAYS RUN FIRST)

python3 00-system/skills/google/google-master/scripts/google_auth.py --check --service gmail

Exit codes:

• 0: Ready to use - proceed with user request
• 1: Need to login - run python3 00-system/skills/google/google-master/scripts/google_auth.py --login
• 2: Missing credentials or dependencies - see [../google-master/references/setup-guide.md](../google-master/references/setup-guide.md)
