Build a small test set

Choose real buying questions rather than only greetings or broad prompts. Keep the expected facts and source URLs beside each case. Test in the same language and widget configuration as the storefront.

Cover different situations

Use these patterns and adapt them to products you actually sell.

CaseWhat a useful answer should do
Exact product specificationIdentify the model and explain the requested attribute using the relevant product information.
Follow-up questionKeep the product context when the customer asks ‘Does it also work by cable?’
Current delivery or priceUse current shop information, distinguish variants, and avoid making up an unavailable date.
Ambiguous referenceUse available conversation or page context and ask a short clarification only when needed.
Unknown informationExplain the useful part, identify the unknown fact, and offer a specific next step.
Unsuitable productExplain the mismatch and suggest a relevant alternative only when supported.

Evaluate the whole response

Check the answer, product links, variant, language, and tone. A technically correct sentence can still be unhelpful if it ignores the customer's main question. A polite apology does not replace an answer or a useful next step.

Correct and retest

If a fact is missing, improve the source or connect the appropriate additional page. If the source is correct but the answer is poor, use the available answer-improvement workflow and include the expected wording and evidence. Repeat both the failing case and a related case after the change.
