The conversation

A shopper:

Asks which serum works for oily skin.
Compares two niacinamide products.
Adds a $44 product to the cart but says the price feels high.
Asks, “Is niacinamide actually good for oily skin?”

The last message looks like a general skincare question. In context, it is the shopper’s final concern before deciding whether to buy.

Without Era	With Era
“Niacinamide can help regulate oil and reduce the appearance of pores.”	“Yes. Niacinamide can help regulate oil, and the product in your cart uses an effective concentration.”

Both answers address the ingredient. The second also addresses the purchase decision that led to the question.

What Era adds

Before the model responds, Era supplies a block like this:

[STATE v1] situation=product_in_cart urgency=delayed_purchase_decision [/STATE]
[GOAL v1] active=seek:confirm_ingredient_effectiveness resolved=unresolved [/GOAL]
[VALUE v1] top=[cost:high] [/VALUE]
[INTENT v1] intent=validating(0.90) specificity=specific [/INTENT]
[CAUSAL v1] constraint=price_sensitivity emotion=anxious [/CAUSAL]
[REC v1] action=validate do="Address ingredient effectiveness before purchase" priority=0.70 [/REC]

The model can now see that:

The shopper is validating a choice, not starting new research.
Price is part of the hesitation.
The reply should connect the answer to the pending decision.

Era does not supply product facts or clinical evidence. Your application still needs a trusted catalog or retrieval source.

Integration

const eraContext = await era.turnContext(messages, {
  visitorId,
  sessionId,
});

const reply = await generateText({
  system: `${PERSONA}\n\n${eraContext}`,
  messages,
});

The retailer, shopper, products, and prices in this example are fictional.
