#pragma help is for writing help for the overall operator. To add a "tooltip"-style popup help for a single parameter, use #pragma parmhelp

#pragma parmhelp parameter_name "text"

#pragma parmhelp parameter_name "text"

Sets the tooltip that appears when the user hovers over parameter_name.

#pragma parmhelp amp "Increase this value to add more noise."
displacement bumpy(float amp=0) {
...
}
