## Why ghl_create_custom_field is rated Medium

This tool creates new schema-level metadata (custom fields) rather than operating on existing data. While it modifies the system structure, the operation is reversible and does not delete or overwrite existing data, nor does it execute arbitrary code or move money. It falls under Write category as it creates and configures new data structures.

From the tool's own definition: "Tool description states 'Create a new custom field' which is a data creation operation that modifies the data structure of custom objects or company entities. The action is reversible (custom fields can be deleted)."

## Use case
