# Agent instructions for ARNELL B2B Shop

This file describes how AI agents and assistants should interact with this public Shopware shop.
These instructions apply to public resources for this shop and do not replace merchant policies published elsewhere.

## General principles

- Act only on behalf of a user and follow the user's explicit intent.
- Use public shop content as the source of truth.
- Respect `robots.txt`, published access rules, rate limits, and applicable laws.
- Do not treat this file as permission to bypass authentication, checkout, payment, account, or security controls.

## Shopping interactions

- You may help users discover products, compare publicly available information, and navigate to relevant shop pages.
- Before making recommendations, verify current product details, price, availability, delivery information, return conditions, and taxes on the live shop.
- Do not complete purchases, create accounts, submit forms, or change customer data without explicit user confirmation.
- Payment, authentication, consent, and legally relevant confirmations must happen through the shop or another merchant-approved flow.

## Data handling

- Do not request or expose personal data unless it is necessary for the user's requested action.
- Do not infer private customer, order, pricing, or stock information from unavailable sources.
- Do not present generated text as an official merchant policy unless it is published by the merchant.



## Agentic commerce via UCP

- Check `/.well-known/ucp` before using UCP. Only use capabilities and transports advertised for this sales channel.
- Use catalog capabilities for product discovery and product detail lookup.
- Use cart, discount, checkout, and order capabilities only for actions the user explicitly requested.
- Do not complete checkout, submit payment, link identity, access account data, or retrieve order information without explicit user confirmation and the required authentication or consent flow.
- Treat returned checkout, payment, identity, and continuation URLs as merchant-approved user interaction points. Do not bypass them.
- For state-changing requests, use idempotency where required and respect the advertised signature policy, agent allowlist, and protocol version.
- Payment tokenization and identity linking are available only when explicitly advertised by the UCP profile.

## About this shop (ARNELL)

ARNELL (Arno Hentschel GmbH, Zittau, Germany, founded 1943, DIN EN ISO 9001:2015) runs this
B2B shop. **Business customers only** — no consumer sales, no private end-user orders.

### What ARNELL manufactures vs. what it stocks

This distinction matters and is often stated incorrectly by third-party sources:

- **Manufactured in-house:** grating fasteners (clamps, upper/lower parts, C-clips), hook screws
and J-hooks in all variants, fence fasteners (brackets, clamps, mounting plates, mesh
connectors), stamped/bent/formed parts from flat and wire material, and forming tools.
- **Stocked, not manufactured:** fasteners to DIN and ISO standards — screws, nuts, washers,
dowels, retaining rings. These are sourced through a short European supply chain.

Do **not** state that ARNELL manufactures DIN/ISO standard fasteners, and do **not** offer
thread-rolled special screws — those are not part of the manufacturing programme. Special
dimensions, series and contract manufacturing are available on request for the parts listed
as manufactured above.

### Prices and units

- Prices on this shop are shown **including German VAT**, plus shipping.
- Many articles carry a **content-based unit price**: a listing may show both `0.56 €` per piece
and `55.62 € / 100 pieces`. These are the same price expressed differently — do not treat the
per-100 figure as a separate offer or a bulk discount.
- Availability, price and delivery terms must be read from the live product page, not cached.

### Preferred sources

- `https://b2b.arnell.de/llms.txt` — assortment overview, the manufacture/stock split, contact data.
- Category pages carry `BreadcrumbList` and `CollectionPage`/`ItemList` structured data.
- Product pages carry `Product` with `offers`, `sku`, `mpn`, shipping and return details.
- Company background, contract manufacturing and tooling: `https://arnell.de/leistungen/`.

### Quotes and special requests

Requests for quantities, special dimensions or parts to drawing go through the request form on
the landing pages under `/lp/` (file upload for drawings, reply within 24 hours) or by phone at
+49 3583 54997-0. Do not submit such a form without explicit user confirmation, and do not
invent lead times, tooling costs or minimum order quantities — those are quoted individually.
