WHY IT NEEDS A POLICY

Why setup_validation needs a policy

This tool sets up/configures request validation, which involves creating or modifying configuration files, middleware, or code artifacts. It is a Write operation (creates or modifies project files reversibly). No evidence of code execution, deletion, or financial operations. Confidence is moderate because the description is brief and doesn't detail exactly what files or configurations are created.
