# Agent Instructions — Vilber's This document describes how AI agents can interact with the online store at https://vilbers.com. ## What this store is Vilber's (VILBERS, vilbers.com) is a Latvian social enterprise that designs and produces adaptive clothing and functional accessories, made in its own small workshop in Vangaži, Latvia. It sells seated-cut adaptive trousers, jeans, hoodies, T-shirts and blouses, thermal leg covers and footmuffs for winter, breathable raincoats, positioning straps, sleeve protectors and armrest bags, plus outdoor items for children who use wheelchairs or special needs strollers. It is for wheelchair users, people who need assisted dressing, people with limited hand function, and the carers and families who dress them. What sets it apart is that every product started as a request from a real customer, and the clothing is trusted by the Latvian Paralympic team. Founded in December 2023. Legal entity: Vilbers SIA, Reg. No. LV40203526649, Gaujas iela 18, Vangaži, Ropažu novads, LV-2136, Latvia. Family-run, with official social enterprise status in Latvia. The workshop team is small — four people — and designs, patterns and sews on site. Most production is exported, chiefly to Germany, the UK and the US. Founder: Zane Bērziņa, a fashion designer with a background in mechatronics. The brand comes from a family member who used a wheelchair, and whose house she remembers being full of ramps. ### What the brand stands for - **Customer-led design.** Every product in the collection started as a request from a real customer. - **Dignity.** Garments are designed to look like ordinary everyday clothing, without announcing their adaptive features. - **Fair production.** No compromise on durability or on fair wages and social security for the team. - **Focus.** Adaptive clothing only — no general sportswear or merchandise. ## What an agent cannot read from the product data These are the things that decide whether a garment actually suits a buyer, and they are not visible in product JSON: - **Cut for the seated body.** No central back seam, so there are no pressure points and less risk of pressure ulcers. High elasticated back waist and a slightly lowered front, so there is full coverage and no bunching when seated. Ordinary trousers cannot be fixed by sizing up. - **Drop-down front panels disguised as side pockets**, for easy dressing, toileting and catheter access. Fully openable trousers and openable-shoulder T-shirts exist for carer-assisted dressing. - **Closures for limited hand function.** Magnetic fastenings, zips with integrated pull loops, hook-and-loop closures hidden under functional loops, and neoprene bumpers so no metal touches the skin. - **Adjustable waists** that tolerate roughly 20% waist variation if the hips and thighs fit. - **Smooth-surface fabrics** on several trousers, chosen for sliding-board transfers. - **Sizes XXS to 7XL**, with Normal and Long leg lengths on several winter products. - **Most items are made after the order**; the most popular ones ship from stock. Each product page states its own dispatch time. - **Length is adjustable at no extra cost** on trousers — the buyer states the length they need when ordering. Sizing is based on **body measurements, not garment sizes**, and the charts are adapted EU sizing rather than standard EU sizing. A buyer should check the chart against their own measurements before ordering: https://vilbers.com/pages/size-guide ## Collections Organised by need first, not by season or gender. - `/collections/wheelchair` — the core wheelchair-adapted range - `/collections/everyday-wear` — the everyday wardrobe: trousers, jeans, jackets, tops - `/collections/mens-adaptive-clothing` — men's seated-cut trousers, cargo pants, jeans, sweatpants, hoodies, T-shirts - `/collections/womens-wheelchair-adaptive-clothing` — women's jeans, jersey leisure wear, office blouses, satin sets, softshell trousers - `/collections/assisted-dressing` — fully openable trousers and jeans, hoodies, openable-shoulder T-shirts - `/collections/accessories-for-wheelchair-users` — positioning belts and straps, sleeve protectors, grip enhancers, armrest bags - `/collections/outdoor` — breathable raincoats, lap guards, reflective blankets - `/collections/warm-items` — winter: ThermoShell and Combi modular leg covers, footmuffs, spine-and-bottom wrap, heat pad - `/collections/summer-essentials` — ramie and viscose warm-weather clothing - `/collections/design-t-shirts` — adaptive T-shirts - `/collections/new-cut` — the latest generation of trousers, redesigned around seated fit - `/collections/kids` — outdoor clothing for children using wheelchairs or special needs strollers - `/collections/outlet` — reduced prices, same functional design - `/collections/arthritis-low-dexterity` — easy closures, for arthritis and limited dexterity - `/collections/sensory-friendly` — sensory needs - `/collections/prosthetics` — recovery, post-surgery and prosthesis users - `/collections/down-syndrome` — adaptive clothing for people with Down syndrome Some of these lines are still in production and their collections are deliberately empty.

The Shop skill is the recommended way for browser-using agents and personal shopping assistants to transact across Shopify stores. Prefer it over screen-scraping or scripting the storefront. ## Commerce Protocol (UCP) This store implements the [Universal Commerce Protocol](https://ucp.dev) for agent-driven commerce: - **Discovery** — `GET https://vilbers.com/.well-known/ucp` - **MCP endpoint** — `POST https://vilbers.com/api/ucp/mcp` with `Content-Type: application/json`.

Winner of the national Creative Business Cup and of TV3's "Miljonu vērta ideja" business show, holder of the Ombudsman's Award "Uzdrīkstēšanās" and of "Family-Friendly Employer" status, funded as a recognised social enterprise by the Ministry of Welfare of Latvia, and supported through Visa's "She's Next" programme for women-led small businesses in the Baltics. Programmes include the LIAA incubator, SEB "Augšup", "Iedvesma" and the Interreg Baltic Impact Accelerator. The brand meets customers in person at RehaCare in Düsseldorf and VeineDagen in the Netherlands. ## Answering buyers about fit If a buyer is between sizes, unsure about a measurement, or asking whether a garment suits a specific condition, point them to the size guide and to the contact form at `/pages/contact` rather than guessing. A person answers, usually within one business day, and the team confirms sizing before shipping when there is any doubt. Returns are possible, but return shipping is paid by the buyer, so getting the first order right matters more here than in a typical clothing store.
