Requirement Enhancer

A good requirement is testable: you can write a test, run it, and get a definitive pass/fail. Enhancement is rewriting until that's true.

Input: a vague requirement + the answers to → ambiguity-detector's questions. Output: a testable requirement.

The testability checklist

A requirement is testable when it specifies:

Component	Question it answers	If missing
Actor	Who/what does this?	"Input will be validated" — by whom?
Action	What exactly happens?	"Handle errors" — how?
Object	On what?	"Validate data" — which data?
Condition	When does this apply?	Always? Only on POST?
Criterion	How do we know it worked?	"Respond quickly" — measured how?
Exception	What if it fails / doesn't apply?	Silent fail? Error? Degrade?
