WHY IT NEEDS A POLICY

Why change_password needs a policy

This tool modifies a user's password, which is a sensitive write operation. While it is reversible in principle (password can be changed again), unauthorized or erroneous use could lock out legitimate users or enable account takeover. It falls under Write as credentials are being updated, but carries high severity due to the security impact of credential manipulation.

From the tool's definition Tool name 'change_password' and description 'Kullanıcı şifresini değiştirir' (Turkish for 'Changes user password')
