WHY IT NEEDS A POLICY

Why createTextMessage needs a policy

This tool creates a new record (text message log entry) in the Follow Up Boss CRM system. While it does not actually send an SMS (which would be Execute), it irreversibly adds data to the system that persists. This is a Write operation because it modifies the CRM state by creating a new communication record.

From the tool's definition Tool description explicitly states it 'LOG[s] a text message' and 'records' it in the system. The verb 'createTextMessage' combined with 'log' and 'records' indicates data creation/modification.
