## Why bulk_delete_custom_fields is rated Critical

This tool permanently removes custom field definitions from the instantKOM platform. Deletion of field definitions is a destructive operation that cannot be undone and affects data structure integrity across the system. The ability to delete up to 100 definitions at once amplifies the blast radius.

From the tool's own definition: "'Delete multiple custom field definitions at once' — irreversibly removes data structures; uses the verb 'Delete' which signals permanent removal without recovery option."

Risk signals: Bulk/mass operation — affects multiple targets

## Use case
