## Why ghl_update_custom_field is rated Medium

This tool modifies configuration data (custom field properties) within the CRM system. While it changes existing data, updates are typically reversible through subsequent update operations, distinguishing it from destructive actions. The blast radius is medium because incorrect modifications could affect data validation or display across the system, but the changes are not permanent deletions and can be corrected.

From the tool's own definition: "Tool description states 'Update an existing custom field by ID. Can modify name, description, options, and other properties.' The verb 'update' and the ability to modify field properties confirms this is a write operation that creates or modifies data…"
