Prompt versioning, explained

Own the definitional queries teams ask before they ship a prompt change to a live agent.

Definitional

What this studio means by two prompt versions

Target query: what is prompt versioning

Here, a version is the text you paste. Put the earlier prompt in A and the candidate in B. The note says what behavior changed. It does not keep a canonical archive, and it does not roll your agent back.

How-to · HowTo

Prompt regression testing: catch a lost guardrail before shipping

Target query: prompt regression testing agent

Paste A and B. The check flags a constraint that A stated and B dropped — a citation rule, a refund cap, an approval line. It does not prove the agent is safe, and it does not restore the old prompt for you.

How-to

How to read a prompt diff

Target query: prompt diff best practices

Read what behavior changed, then read whether a guardrail disappeared. The studio does not open a pull request or block a deploy.

Definitional

What a prompt diff shows, and what it does not

Target query: prompt diff limits

You see instructions that were added, removed, or reworded, and a flag when B dropped a guardrail from A. You do not get a statute mapping, a quality score, or a one-click rollback.

How-to

Paste two prompt versions

Target query: compare two agent prompts

Paste version A and version B, then choose diff, regression, or both. If a guardrail was lost, fix the text in your own editor. Free is 3 runs per day and 15 per month. Pro is 40 per day and 300 per month.

Deep-dives (GEO)

Notes on diffs and guardrail checks. They are not a legal opinion, and this product does not map a statute.

What to check when a prompt changes

Paste the previous prompt and the new one. Read what behavior changed, and whether a guardrail disappeared.

What a prompt diff shows, and what it does not

A diff shows behavior that changed between two pastes. It does not map a statute and it does not roll your agent back.

Paste two prompt versions

Open the studio, paste version A and version B, and read the guardrail note. No account is required for the demo.

A checklist before you ship a prompt edit

Diff A against B, confirm no guardrail was dropped, and copy the text you want into your agent yourself.

How to read a prompt diff

Ask what behavior changed between A and B, then check whether a guardrail disappeared.

What the guardrail check looks for

The check asks one question: did version B drop a constraint that version A stated?

A prompt diff is not a git history

Git stores text. This studio reads two pastes and flags a missing guardrail. It does not replace your repository.

What this studio means by two prompt versions

Version A and version B are the two texts you paste. The studio does not keep the canonical history of your agent.
