How to read a prompt diff

Prefer the behavior line

A character diff tells you which letters moved. The studio line should tell you which instruction was added, removed, or reworded.

Pair it with the guardrail flag

A diff can look small and still drop "always cite a source." Read that flag before you treat the edit as safe.

Do not treat the note as a merge robot

Nothing here opens a pull request, blocks a deploy, or restores an old prompt in your runtime. You copy the text.

FAQ

What is a good diff for this tool?

One that names the instruction that changed, plus a yes or no on whether A’s guardrail is still in B.

Should I ship when the flag is empty?

An empty flag means this check did not see a dropped constraint. It does not mean the agent is safe.

## Disclaimer

AgentPrompt compares two pasted prompt versions and flags a guardrail present in A and missing in B. You copy any older text back yourself. The note is decision-support, not a certificate, and this product does not map a statute.

Paste version A and version B in the studio — open AgentPrompt.
