What a prompt diff shows, and what it does not

What you see

After you paste A and B, the note describes instructions that were added, removed, or reworded. The regression line calls out a constraint that existed in A and is gone in B.

What you do not see

No statute mapping and no obligation articles.
No one-click rollback into your agent.
No hidden test set and no quality score.
No claim that the agent is safe because the diff looked small.

A short example

A says "Always cite a KB article." B says "Cite a KB article and offer a refund under $20." The diff should show the new refund line. If a later edit drops the citation sentence, the check should flag that loss.

FAQ

Is this a legal review?

No. The page compares two prompt texts. It does not interpret a statute.

Can I roll the agent back from here?

No. Copy the older text into your own system if you want it back.

What is a guardrail in this tool?

A constraint written in A — cite a source, ask for approval, cap a refund — that B no longer contains.

## 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.
