WHY IT NEEDS A POLICY

Why assign_expert needs a policy

This tool performs classification and assignment of issues to experts, which creates or modifies records (assignments) in the help desk database. This is reversible data modification, making it Write rather than Execute. Severity is low because assignment errors have limited blast radius—they misdirect support tickets but don't delete data, execute arbitrary code, or cause financial harm.

From the tool's definition Tool 'assign_expert' with description 'Analyze the problem description, classify into standard categories' suggests it modifies system state by routing/assigning issues to experts in the Django DB backend (mentioned in server description).
