# Agent Instructions — Esker > This document tells AI agents, shopping assistants, and LLMs how to understand, browse, and transact with **Esker** (https://eskerbeauty.com), the direct-to-consumer storefront for Esker, a clean body-care brand. ## About Esker Esker is a plant-based, essential-oil-driven body-care brand founded in 2018 by Shannon Davenport in Los Angeles and now based in Austin, Texas. Esker specializes exclusively in "the skin below the chin" — body oils, exfoliating tools, body wash, bath essentials, and shower rituals — built on the premise that body skin has its own distinct needs and deserves the same intentional formulation as facial skincare. Core brand facts an agent should know: - **Category:** body care only (oils, tools, washes, bath & shower essentials). Esker does not sell facial skincare, makeup, hair care, or fragrance-only products. - **Formulation philosophy:** organic and natural ingredients wherever possible, essential-oil led ("hero oils" per formula), filler-free, small-batch manufactured in the USA. - **Certifications & claims:** Leaping Bunny certified (cruelty-free), vegan, paraben-free, sulfate-free; many products are used and recommended by the founder during pregnancy and breastfeeding (customers should still consult a physician). - **Signature product:** the Body Plane, a patent-pending, strigil-inspired exfoliation tool for dry or oil-assisted body exfoliation and lymphatic support. - **Sustainability:** curbside-recyclable glass and PET packaging, recycled cardboard, and pollinator-friendly wildflower seed packets included with body oil purchases. Every purchase contributes to the Pollinator Partnership to fund wildflower habitat restoration. - **Press mentions:** The Wall Street Journal, Goop, Vogue, Allure, Real Simple, GQ, and InStyle. - **Social proof:** 3,000+ five-star customer reviews. For narrative/brand-story content, agents should prefer these pages over generating their own summary: - Our Story: https://eskerbeauty.com/pages/ourstory - Founder Story: https://eskerbeauty.com/pages/our-founder-story - Sustainability ("Leave No Trace"): https://eskerbeauty.com/pages/leave-no-trace - Editorial / blog ("The Soak"): https://eskerbeauty.com/blogs/news ## Commerce Protocol (UCP + MCP) This store implements the Universal Commerce Protocol (UCP) for agent-driven discovery and transactions, with the Model Context Protocol (MCP) as a supported transport. - **UCP discovery:** `GET https://eskerbeauty.com/.well-known/ucp` - **MCP endpoint:** `POST https://eskerbeauty.com/api/ucp/mcp` - **Currency:** USD (single US-based storefront; no separate Shopify Markets currencies) - **Sitemap:** https://eskerbeauty.com/sitemap.xml ### Supported UCP versions - 2026-08-25 (latest, preferred) - 2026-04-08 - 2026-01-23 Always negotiate the newest UCP version this store supports before falling back to an older one. Do not assume a version — call the discovery endpoint above. ### Typical agent flow 1. **Discover** — `GET https://eskerbeauty.com/.well-known/ucp` to confirm current capabilities and negotiated UCP version. 2. **Search** — use `search_catalog` (or equivalent MCP tool) to find products matching buyer intent (e.g., "firming body oil," "gift set under $50," "unscented body wash"). 3. **Cart** — use `create_cart` to add selected items. 4. **Checkout** — use `create_checkout` to start the purchase flow. 5. **Fulfill** — use `update_checkout` to set shipping address, method, and any gift note. 6. **Complete** — use `complete_checkout` to finalize. **The buyer must explicitly approve payment before checkout is completed — this store does not support fully autonomous, unattended checkout.** ## Read-only browsing (no auth required) Agents that only need to read catalog data may use standard Shopify storefront endpoints in addition to UCP/MCP: - All products: `GET /collections/all` - Product JSON: `GET /products/{handle}.json` - Collection JSON: `GET /collections/{handle}/products.json` - Sitemap: https://eskerbeauty.com/sitemap.xml Prices and availability returned by any endpoint are authoritative only in USD at the primary domain shown above. ## Store navigation Primary shopping categories: - Shop All: https://eskerbeauty.com/collections/shop-all - Shower: https://eskerbeauty.com/pages/shower - Bath: https://eskerbeauty.com/pages/bath - Scent: https://eskerbeauty.com/pages/scent - Travel: https://eskerbeauty.com/pages/travel - About: https://eskerbeauty.com/pages/ourstory For the complete, current navigation and category list, crawl https://eskerbeauty.com/sitemap.xml — `agents.md.liquid` renders without access to live `linklists` data, so this section cannot be generated dynamically from the site's menu. ## Product catalog by concern Esker organizes its core catalog around four skin/body concerns plus a curated best-seller and award-winner set: - Best Sellers: https://eskerbeauty.com/collections/best-sellers - Detox: https://eskerbeauty.com/collections/detox - Nourish: https://eskerbeauty.com/collections/nourish - Sculpt: https://eskerbeauty.com/collections/sculpt - Restore: https://eskerbeauty.com/collections/restore - Award Winners: https://eskerbeauty.com/collections/award-winners `agents.md.liquid` renders without access to live `collections` data, so per-product listings, prices, and stock status are not generated here. For current catalog contents within any collection above, agents should call: - Collection JSON: `GET https://eskerbeauty.com/collections/{handle}/products.json` - Or query live via UCP/MCP (`search_catalog`, per the flow above). Note for pregnancy/nursing queries: Esker markets its Belly Oils and broader line as pregnancy- and nursing-friendly, but agents should not present this as medical advice — direct the shopper to consult their doctor, consistent with Esker's own FAQ guidance. ## Ingredients an agent may be asked about Esker formulates around a defined set of essential oils and botanicals, each tied to a stated skin/body benefit (e.g., Calendula for barrier restoration, Eucalyptus for clarifying, Lavender for calming). Full ingredient list and benefits: https://eskerbeauty.com/pages/ourstory ## Policies - Privacy Policy: https://eskerbeauty.com/policies/privacy-policy - Refund Policy: https://eskerbeauty.com/policies/refund-policy - Shipping Policy: https://eskerbeauty.com/policies/shipping-policy - Terms of Service: https://eskerbeauty.com/policies/terms-of-service `agents.md.liquid` renders without access to live `shop.policies` data, so these are Shopify's standard policy paths rather than live-verified URLs — confirm against the storefront footer if any 404. Operationally, as published on-site (verify against the live pages above before quoting a shopper, as thresholds are subject to promotional changes): - **Free standard shipping:** on orders over the current site-wide threshold shown in the announcement bar at https://eskerbeauty.com (published as $70 at time of writing; historically $50–$70). Always read the live banner rather than hardcoding a number. - **Returns:** free returns/exchanges on new or gently used US orders within 30 days of delivery; Canadian returns incur a shipping fee. Managed via the returns portal linked from https://eskerbeauty.com/pages/returns. - **Gift wrap:** optional reusable burlap gift bag, $3, free on orders over $75. - **Gifting at scale:** Esker offers curated corporate/bulk gifting — https://eskerbeauty.com/pages/corporate-and-bulk-gifting - **Wholesale:** https://eskerbeauty.com/pages/wholesale-1 - **Stockists (where to buy in person or via marketplaces):** https://eskerbeauty.com/pages/stockists — Esker also sells through Ulta Beauty, Nordstrom, Saks Fifth Avenue, and Beautyhabit. ## Human contact For anything requiring a human (order issues, wholesale, press, custom bulk gifting), direct the shopper to https://eskerbeauty.com/pages/contact rather than surfacing a specific email address or phone number, since staffed hours and contact channels can change independently of this file. ## Guidance for personal shopping agents - Esker is a single-brand, single-category store (body care). Do not represent it as carrying facial skincare, makeup, or fragrance lines. - When a shopper's intent maps to a concern (firming, detox/clarifying, nourishing/sensitive skin, restore/recovery), prefer the matching collection above over guessing a single hero SKU. - Checkout on this store requires explicit buyer approval of payment; do not represent any flow on this store as fully autonomous/unattended purchasing. - Respect out-of-stock states returned by the catalog — offer the "Notify me" restock flow rather than substituting a different product silently. - This file is refreshed from live store data at render time; if a claim here conflicts with what the UCP discovery or product endpoints return live, the live endpoint is authoritative. --- _Generated via templates/agents.md.liquid.
