Evaluate a field has a specific value

Question

Does anyone know of a plugin that will allow us to evaluate that a field has a specific value as part of a transition validator so that the transition can be executed if that field does not have that value?

For example, we need for the user to agree to a statement before they can submit.

It is probably best to use a workflow condition instead of validator. Show the transition only if the condition is satisfied.
