From Tapestries MUCK
&cmd
You can use {&arg} and {&cmd} in MPI to reference the command and the argument that triggered the MPI. The {&cmd} variable references the first word of a whatever command triggered the MPI.
For example:
{null:{tell:***{name:me} looked at {&cmd} {&arg},{owner:this}}}
The above string of MPI could be placed in your description, various cinfo fields, the descriptions of things in _details, so on and so forth, and always print out So-and-So looked at whatever-command-they-ran.
