WHY IT NEEDS A POLICY

Why set_kid_mode needs a policy

The tool updates account state (kid mode status) but does not delete data, execute arbitrary code, move money, or perform irreversible actions. It's a reversible configuration change typical of Write category. Severity is low because changing kid mode status has minimal blast radius—it affects only content filtering and safety settings for the account holder, with no financial or destructive implications.

From the tool's definition Tool description states 'Set kid mode status' which modifies a user account setting. This is a write operation that changes account configuration on the Lichess platform.
