Verb:DETECT

The DETECT verb is used primarily to find a trap on a container, such as a box, or on a locked door. This verb carries little to no risk to setting off a trap, and generally is used first, before the disarm verb to try to remove a trap.

>help detect

Usage:
    DETECT {container or door} - Attempt to find a trap on a closed and locked container or door
    DETECT {other target}      - Blink in surprise upon noticing someone or something
    DETECT {LEFT|RIGHT}        - Attempt to find a trap on or blink in surprise upon noticing the item in the specified hand

If a trap is found on a container or door, the DISARM verb may then be used to try to render the trap inactive.
