This tool creates (reversibly modifiable) schema extensions rather than deleting or irreversibly destroying data. It is Write rather than Execute because it operates on structured database schema creation, not arbitrary code execution. Severity is medium because misconfiguration of custom fields could disrupt workflows or data integrity, but the operation is reversible through field deletion.

From the tool's own definition: "Tool name is 'ghl_create_custom_field' and description states it 'Create[s] a new custom field for custom objects or company'."
