Task: reorder Packrift SKU 1066 for quantity 1.

Required tool sequence:
1. Run tools/list and confirm Packrift MCP is connected.
2. Call get_cart_handoff_candidates with sku="1066", limit=1, source_context="goose_agent_first_cart_run", journey_id="mcp_install_goose_agent_1066_53472879935856", and result_set_id="mcp_install_first_run_goose_agent".
3. Call get_pricing with variant_ids=["53472879935856"], quantity=1, selected_sku="1066", selected_handle="10x6x6-ect-32-kraft-long-corrugated-boxes-25-bundle", match_type="agent_prompt_first_run", source_context="goose_agent_first_cart_run", journey_id="mcp_install_goose_agent_1066_53472879935856", and result_set_id="mcp_install_first_run_goose_agent".
4. Call check_inventory with variant_ids=["53472879935856"], selected_sku="1066", selected_handle="10x6x6-ect-32-kraft-long-corrugated-boxes-25-bundle", match_type="agent_prompt_first_run", source_context="goose_agent_first_cart_run", journey_id="mcp_install_goose_agent_1066_53472879935856", and result_set_id="mcp_install_first_run_goose_agent".
5. If the live checks pass, call create_cart_url with sku="1066", quantity=1, selected_sku="1066", selected_handle="10x6x6-ect-32-kraft-long-corrugated-boxes-25-bundle", match_type="agent_prompt_first_run", source_context="goose_agent_first_cart_run", mcp_source_context="goose_agent", mcp_install_target="generic_streamable_http", journey_id="mcp_install_goose_agent_1066_53472879935856", result_set_id="mcp_install_first_run_goose_agent", and utm_term="1066".

Return the product title, live unit price and currency, inventory status, and the measured cart URL.
Success requires a cart URL starting with https://mcp.packrift.com/r/cart/1066.
Do not place an order. If any live check fails, stop and say exactly which check failed.

## Success Signals

- tools/list returns the current Packrift tool surface
- get_cart_handoff_candidates returns SKU 1066
- get_pricing returns a live unit price and currency
- check_inventory returns in_stock before cart handoff
- create_cart_url returns a URL starting with https://mcp.packrift.com/r/cart/1066
- curl shell runners open the returned /r/cart URL once to record mcp_cart_landing without following Shopify checkout
- Every tool call carries source_context, journey_id, and result_set_id; create_cart_url also carries mcp_source_context and mcp_install_target so cart attribution survives MCP hosts that strip endpoint query parameters
- usage snapshot records a source-attributed create_cart_url tool call when the workflow is run from a tracked install

## Operating Rule

This is a thin first-run wrapper around https://mcp.packrift.com/mcp. Do not treat it as a Packrift CLI, checkout, or alternate buyer surface.
