Version Your Prompts Like Code

Prompts are code

A prompt change can break your app as surely as a code change. So treat prompts the same way: version them, review them, and test them.

Practices

• Store prompts in your repo, not scattered in code or a dashboard only.
• Template variables instead of string-concatenating user input.
• Tie each prompt to an eval so you can measure changes.
• Log which prompt version produced each output.

Payoff

When quality dips, you can see exactly which prompt changed and roll back. This discipline turns prompt-tuning from guesswork into engineering you can trust.
