WHY IT NEEDS A POLICY

Why complete_google_auth needs a policy

This tool completes an OAuth flow by exchanging an authorization code for access/refresh tokens, which are then stored/persisted. This is a Write operation as it creates and stores credential tokens. It has medium severity because misuse could grant unauthorized access to Google Calendar data, but it requires a valid authorization code from a prior auth step.
