Skill history and Test on case

A skill is the AI's rulebook for a category, so one bad change affects every single reply in the category. That is why, under Skills, you can see earlier versions, restore them and test a change before you save it.

History: see and restore earlier versions

Every time a skill is saved, Nemma stores the version. Click History at the top of the skill's card, next to Save. A list of the versions opens, newest first:

• the version number, date and who wrote it
• what changed compared with the version before, for example 3 lines added, 1 removed
• the first line of the text. The current version has the label Current

Click View next to a version to read the whole text, and Hide to collapse it.

Restore a version

1. Click Restore next to the version you want to go back to.
2. Confirm with Restore version 4 (with the right number).

The old text becomes the skill's new, current version. No versions disappear: the restore goes at the top of the history, so you can always undo it again.

Everyone on the team can see the history, also an agent without permission to edit Skills. Restoring requires the same permission as editing a skill, that is the owner or an agent with Can edit Skills (see Team and permissions). Without permission it says Only the owner or someone with permission can restore a version.

Test on case: try a change without risking anything

Under the skill text is the Test on a case button (only for those who may edit Skills). It lets you see what the AI would reply to a real case with the text that is in the field right now - even if you have not pressed Save yet.

1. Write or edit in the skill.
2. Click Test on a case.
3. Under Choose a case are the 10 most recent cases in the category. Choose one.
4. Click Run test. It can take up to a minute.

Nemma replies once to the customer's latest message in the case and shows the reply under Draft. If the AI suggests an action, for example cancelling an order, it only appears as text under Actions the AI would suggest. If the AI would have passed the case to a human instead of replying, that is shown too.

Nothing happens in reality. The test sends no email, saves no draft, does not change the case and carries out no action in Shopify. It says Test only - nothing has been sent or saved. The customer never sees anything.

Good to know:

• There is a limit of 20 tests an hour for the whole shop. The page tells you how many are left. If the limit is reached, you can try again in a little while.
• A test uses the AI just like an ordinary reply and counts towards your usage.
• If you have edited the text after the test was run, the page warns that the draft was made with the earlier text. Run the test again.
• The test is deliberately stricter than a real case: orders you have confirmed as placed with a different email are not included. See Order placed with a different email.

A good way of working: edit the skill, test on two or three different cases, save, and use History if you regret it. Read more about what a skill contains in Categories and skills.
