WHY IT NEEDS A POLICY

Why mikrotik_set_user_ssh_keys needs a policy

This tool modifies user authentication material (SSH public keys) reversibly. While credential manipulation carries significant risk (an attacker could lock out legitimate users or add backdoor access), it is classified as Write rather than Execute or Destructive because: (1) the operation itself is a data modification, not execution of arbitrary code; (2) it is theoretically reversible by re-setting keys to correct…

From the tool's definition Tool name contains 'set' and description states 'Sets SSH public keys for a user' — this is a modification operation that creates or updates user authentication credentials.
