WHY IT NEEDS A POLICY

Why update_practice_area needs a policy

This tool modifies existing data (practice area metadata) in a reversible manner. Renaming a practice area does not delete data or trigger external operations, making it a Write category action. Severity is medium because incorrect renaming could cause confusion across case categorization and billing, but the change is easily reversible and has limited blast radius compared to destructive or financial operations.

From the tool's definition Tool description states 'Rename a practice area' which is a modification operation. The sibling tools include create_case, create_client, and other data-creation operations, confirming this server manages organizational data.
