This is an explanation of how you can make a simple script to automatically change your description for various states. For example, you could have your description describe some article of clothing, but only if you're actually wearing that clothing.

First, make an alias to set your default description. For example:
Next, decide what you want to automatically change. Let's say you want to add "She is wearing a red shirt." to the description when you're wearing a red shirt. Think of every line that could indicate when you wear or remove a red shirt. In this case, it would be wearing, removing, and decaying. So make triggers for all of those things:

These triggers set a variable that indicates whether or not the shirt is worn, and then sends your description alias. Now, add the red shirt part to your description alias.

That will check to see if the RedShirt variable is true, and if so, add the red shirt line to your description. You can also add a line that appears if you're not wearing a red shirt.

That will check to see if the RedShirt variable is true and add the red shirt line if it is, or add the other line if it isn't.
If there's something you want to show in your description, but there's no way to trigger it, you can also make aliases for it.

You can make it more complicated than this, and you can surely write better descriptions than this, but this should at least mean you have no excuse for leaving things in your description that are not currently true.
