Google Connect

Setup wizard for Google Workspace integration.

Purpose

Guide users through connecting their Google account to Nexus. One OAuth setup grants access to all 7 Google services: Gmail, Docs, Sheets, Calendar, Drive, Tasks, and Slides.

Shared Resources

This skill uses google-master shared library:

Resource	When to Load
`google-master/scripts/check_google_config.py`	Always first (pre-flight)
`google-master/scripts/google_auth.py`	For authentication
`google-master/references/setup-guide.md`	Detailed setup instructions
`google-master/references/error-handling.md`	On any errors

Workflow 0: Config Check (ALWAYS FIRST)

Every interaction MUST start with config validation:

bash

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

Purpose: Guide user through complete Google Cloud setup.
