I am trying to make a new text adventure game. In my game, you start trapped in a cell, and need to solve a puzzle to gain a metal pipe. Once you get the metal pipe, you can break open the prison bars. How do I achieve this with quest.

Perhaps you should study the tutorial a bit before you start.
But basically create objects bars and pipe and exit out. Make exit invisible. Give bars a verb break
Script for break
If player is not carrying item pipe
Print you have nothing to do that with.
Else
Print you break the bars out with the pipe
Hide bars
Show exit out
