# Agent Instructions for Houndbiotic

Houndbiotic (https://houndbiotic.co.uk) is an independent Shopify store operated by YALEO LLC, selling pet supplies (dog probiotics and gut health, pet supplements, food, treats, toys, grooming) to the United Kingdom and the United States.
This file gives AI agents, shopping assistants, and autonomous crawlers a direct,
structured way to browse the catalog and — where supported — transact via UCP/MCP.

## Quick facts

- Domain: https://houndbiotic.co.uk
- Category: pet supplies
- Ships to: the United Kingdom and the United States (free); other countries for a flat £16 (USD 20) fee
- Currency: GBP

## Discovery
1. `GET https://houndbiotic.co.uk/.well-known/ucp` — merchant capability manifest (supported
   UCP protocol versions, shopping service, payment handlers).
2. `POST https://houndbiotic.co.uk/api/ucp/mcp` — Model Context Protocol endpoint.
   Content-Type: application/json. Use this for tool discovery and JSON schemas.

## Recommended agent flow
1. Discover capabilities via the UCP endpoint above.
2. `search_catalog` — find products by name, category, or attribute.
3. `create_cart` — build an order from selected line items.
4. `create_checkout` — initialize the purchase.
5. `update_checkout` — set shipping/fulfillment and discount codes.
6. `complete_checkout` — finalize. REQUIRES explicit, contemporaneous buyer
   approval. Agents must never submit payment autonomously.

## Read-only browsing (no authentication required)
- Product listings: `/collections/all`, `/products/{handle}.json`
- Search: `/search?q={query}&type=product`
- Policies: `/policies/shipping-policy`, `/policies/refund-policy`,
  `/policies/privacy-policy`, `/policies/terms-of-service`
- Full context file: `/llms.txt`

## Crawling and citation
All reputable AI and search crawlers (GPTBot, ChatGPT-User, ClaudeBot, Claude-User,
PerplexityBot, Google-Extended, Bingbot, CCBot, Applebot-Extended, Amazonbot,
Bytespider, meta-externalagent, and others) are explicitly welcomed to crawl, index,
summarize, and cite this catalog. See `/robots.txt` for the full machine-readable policy.

## Hard constraints
- Do not complete checkout, payment, or order placement automatically.
- No scripted form-fills, browser automation, or end-to-end agent flows that
  finalize payment without an explicit, contemporaneous human approval step.
- Respect `/robots.txt` disallow rules for admin, cart, checkout, and account
  paths outside of the UCP/MCP flow described above.
