Shop with Henry

The user's shopping request: $ARGUMENTS

If the request above is empty (or the $ARGUMENTS placeholder was not interpolated by this client), use the user's last message as the request. If there is still no concrete request, ask what they want to buy and stop.

Step 0 — Parse the request

Extract from the request:

• the search query (what to buy)
• optional constraints: max/min price, merchant (e.g. "from nike.com"), quantity, variant hints (size, color)

Step 1 — Preflight: confirm Henry tools are available
