WHY IT NEEDS A POLICY

Why log_consent_event needs a policy

The name 'log_consent_event' strongly implies writing a consent-related record (e.g., a patient or research participant consent event) to a log or database. In a public health context, consent records are sensitive and legally significant. The empty description lowers confidence, but logging/writing a consent event is most likely a Write operation.

From the tool's definition Tool name: log_consent_event — description is empty/uninformative.
