You are looking at a command called detect

detect life
detect code
detect boring

The detect life command scans your location and any adjacent one for signs of life. Each item shown has 'living' material and thus can be attacked.

The detect code command scans your location for items that are coded.

The detect boring command scans your location for items that you own that aren't written in and aren't coded, including the location itself. Future plans on this are to search code for missing reactions so you can make your objects even more interactive.

About life in COW:
To make a living creature, read the command called spawn;

If you are not alive, try cpr me.

If you create a creature and you want the creature to be alive, then cpr the creature. Note: creatures created by spawn are able to spontaneously return to life.
