How does the tool evaluate economic clarity?

By using `analyze_offer_economics`, the tool checks if the text explicitly mentions the price difference (value-delta) and uses specific numbers rather than vague terms.

Can it identify words that cause buyer hesitation?

Yes, the `audit_copy_sentiment` tool counts friction words like 'difficult' or 'complex' that might induce psychological resistance.

How is product relevance measured?

The `analyze_purchase_relevance` tool looks for linguistic bridges that connect the consumer's original purchase to the new recommendation.
