Prompt version control and A/B testing

Someone improved the customer-reply prompt to make responses friendlier. Two weeks later the drafts are missing a policy caveat they used to include, and nobody can find the previous version. The friendliness change had removed a constraint that was doing real work, and there is no way back.

You need

Prompt's job: draft customer email replies, seen by customers. Current version: includes a constraint 'always state the return window that applies to this category, from the knowledge base'.

Tool

Your prompt library's version and notes fields

You get

1. THIS IS ONE CHANGE — good.

Time saved

A structured A/B test takes about two hours and prevents changes that quietly degrade customer-facing output for weeks.
