Workflow 0: Config Check (ALWAYS FIRST)

Every interaction MUST start with config validation:

python 00-system/skills/google/google-master/scripts/check_google_config.py --json

Exit code meanings:

• Exit 0: Fully configured and authenticated - ready to use
• Exit 1: Credentials exist but need to login (run OAuth flow)
• Exit 2: Missing credentials - need full setup

Route based on exit code:

• Exit 0 → Workflow 4 (Already Connected)
• Exit 1 → Workflow 3 (Authenticate)
• Exit 2 → Workflow 1 (Full Setup)

Workflow 1: Full Setup (First-Time Users)

Triggers: "connect google", "setup google", config check returns exit 2
