WHY IT NEEDS A POLICY

Why tm_update_profile needs a policy

The tool modifies profile configuration within TrafficMorph's load-testing system. While the description is empty (reducing confidence slightly), the name and sibling tools clearly indicate this performs reversible data modification rather than destructive deletion, code execution, or financial operations.

From the tool's definition Tool name is 'tm_update_profile' which explicitly indicates modification of an existing profile. No description provided, but the sibling context (tm_create_profile, tm_delete_profile, tm_get_profile) confirms this is part of profile lifecycle management.
