🎯 Why This Exists

Claude is powerful, but without domain-specific guidance it generates Frappe/ERPNext code that looks correct but fails in production.

The #1 cause of AI-generated Frappe failures:

# ❌ WRONG - This fails silently in Server Scripts
from frappe.utils import nowdate
today = nowdate()

# ✅ CORRECT - Server Scripts block all imports
today = frappe.utils.nowdate()

This package encodes 61 hard-won lessons like this into deterministic skills that Claude follows automatically.
