WHY IT NEEDS A POLICY

Why mhs5200_set_frequency needs a policy

Based on the tool name pattern consistent with sibling tools (set_amplitude, set_duty_cycle, set_offset, etc.), this tool writes a configuration value (frequency) to the MHS-5200A signal generator via serial connection. It modifies device state reversibly. Empty description lowers confidence slightly, but the naming convention and server context make Write the clear category.
