Use the Shopify UCP Skill in Codex for Read-Only Catalog Discovery
Plan a global catalog search and check that product comparisons identify the right sellers. The exercise uses a two-product fixture and stops before cart or checkout actions.
中文Setup for Codex
Use Codex with the pinned UCP skill. Live lookups need the UCP CLI, and merchant-scoped workflows have additional setup. This exercise uses fictional products, no account and no payment.
- Open Shopify's pinned source below and copy the complete skills/ucp directory into .agents/skills/ucp in a disposable project, keeping the included scripts and references.
- Open the project in the selected client and load $ucp. Follow the pinned skill's tool preflight for the requested task.
Example task
Give $ucp a simulated catalog for a fictional portable lamp. Include one listing from lamps.example and a second seller that reuses the product title. Ask for a read-only shortlist, the documented global catalog entry point, and the seller domain beside each result.Expected result
The response distinguishes the two sellers by seller.domain, identifies ucp catalog search for global discovery, and keeps the exercise limited to reviewing the supplied fixture.

Frequently asked question
Does a product title establish which merchant sells it?
Use the seller.domain field to distinguish the actual merchant from a brand mentioned in a listing. Confirm the merchant and product variant before acting on a real result.
