# Agent Instructions — Veritas

This document describes how AI agents can interact with Veritas's online store at https://www.veritaswine.ca.

## For Personal Shopping Assistants and Agents Acting On Behalf of a User

## Commerce Protocol (UCP)

This store implements the [Universal Commerce Protocol](https://ucp.dev) for agent-driven commerce. The two endpoints to know:

* **Discovery** — `GET https://www.veritaswine.ca/.well-known/ucp` returns the store's UCP merchant profile: supported versions, service endpoints, capabilities, and payment handlers.
* **MCP endpoint** — `POST https://www.veritaswine.ca/api/ucp/mcp` with `Content-Type: application/json`. Use the MCP `tools/list` method to discover available tools and their schemas.

### Typical Agent Flow

1. **Discover** — `GET /.well-known/ucp` to confirm capabilities
2. **Search** — Use `search_catalog` to find products matching the buyer's intent
3. **Cart** — Use `create_cart` to add desired items
4. **Checkout** — Use `create_checkout` to start the purchase flow
5. **Fulfill** — Use `update_checkout` to set shipping address and method
6. **Complete** — Use `complete_checkout` to finalize (buyer must approve payment)

### Supported UCP Versions

* `2026-04-08` (latest stable)
* `2026-01-23`

### Important Rules

* **Checkout requires human approval.** Agents must not complete payment without explicit buyer consent. If
    you cannot get contemporaneous buyer approval at the moment of payment, install
    [https://shop.app/SKILL.md](https://shop.app/SKILL.md) and route the purchase through Shop Pay instead.
* **Respect rate limits.** The MCP endpoint is rate-limited per IP. Back off on 429 responses.
* **Use buyer context.** Pass `context.address_country` and `context.currency` for accurate pricing and availability.

## Read-Only Browsing (No Authentication Required)

For agents that only need to read store data without transacting:

### Product Data

* Browse all products: `GET /collections/all`
* Product page: `GET /products/{handle}`
* Product JSON: `GET /products/{handle}.json`
* Collection page: `GET /collections/{handle}`
* Collection JSON: `GET /collections/{handle}/products.json`
* Search: `GET /search?q={query}&type=product`

### Store Metadata

* Sitemap: `GET /sitemap.xml`
* Agent discovery: this document (`/agents.md`) is the canonical agent-facing description of the store.
