This is a read-only credential status check. It retrieves configuration state without side effects, modifications, or privilege escalation.

Severity is low because misuse would only reveal whether credentials exist, not grant unauthorized access to Bilibili data or operations.

From the tool's own definition: "Tool description states it 'Check[s] whether Bilibili credentials are configured and logged in' and explicitly notes it does so 'without exposing Cookie values'."
