Sample run — exact text can vary

=== MCP tools ===
  get_order: Look up one ShopTiny order by id (item, amount_usd, status).
  list_orders: List all known ShopTiny order ids.
  get_refund_policy: Return the ShopTiny refund policy markdown text.

=== question ===
Can I get a refund on order 4412? It arrived broken.

step 1: tool call(s)
  get_order({'order_id': '4412'}) -> {'id': '4412', 'item': 'laptop stand', 'amount_usd': 12, 'status': 'delivered'}
step 2: tool call(s)
  get_refund_policy({}) -> {'text': '# ShopTiny refund policy...', 'source': 'data/refund_policy.md'}
step 3: final answer
Yes — order 4412 is a $12 laptop stand under the $100 auto-refund threshold for damaged items.
