# Mishopping — spoke context The user wants to shop — search for products, browse merchants, compare options, build a cart. Mishopping is the reference shopping Miapp in the Whooverse — multi-merchant product discovery and cart management. If you haven't already, fetch `https://poc.whoois.app/whoois-context.md` for the root primer. For checkout (the payment flow that follows cart building), see `https://poc.whoois.app/context/checkout.md`. --- ## What's mishopping.app? A user-facing Miapp focused on shopping discovery. It's the reference implementation showing what a Miapp can do — multi-merchant product search, brand-aware browsing, cross-merchant comparison, drag-and-drop cart building. Eventually, third-party Miapps (mitravel.app, mitbp.app for healthcare, etc.) follow the same pattern. POC scope: 5 mock merchants (Demo Coffee Co, Pretend Books, Imaginary Toys, Mock Music Store, Fake Hardware Hut) with ~100 products + canonical category taxonomy + ACO (Agentic Commerce Optimization) scoring. --- ## Trigger phrases - "Find me {product}" / "I'm looking for {product}" - "Show me coffee" / "Find books about {topic}" - "Compare {product} across stores" - "What's on sale?" - "Show me {merchant}'s products" - "Browse {merchant}" - "Add {N} {product} to my cart" - "Remove the {product} from my cart" - "Show my cart" - "What's in my cart?" --- ## Tools to call (lots — group by intent) ### Product discovery **`mishopping_product_search`** — LLM-visible. Search products across all merchants. Args: `q` (query string), `merchantId` (optional filter), `categoryKey` (optional), `tags` (optional list), `limit` (default 25). Returns a list of products with merchant + name + price + image. **`mishopping_product_view`** — LLM-visible. Renders a single-product iframe with full details + alternatives + add-to-cart CTA. Args: `productKey` or `productId`. ### Merchant browsing **`mishopping_merchant_browse`** — LLM-visible. Renders the iframe browsing a single merchant's catalog. Args: `merchantId`. Shows merchant brand header (logo + colors) + category browse + product grid. **`mishopping_cross_merchant_browse`** — LLM-visible. Renders an iframe with cross-merchant variety-first browsing. Args: `q` (required). Shows products from multiple merchants in one view, with merchant chips + ACO fit indicators. ### Comparison **`mishopping_comparison_render`** — LLM-visible. Renders the multi-merchant comparison iframe (e.g., "the same coffee bean from three different shops, ranked by ACO fit"). Used when the user wants to see merchant trade-offs side by side. ### Cart management **`mishopping_cart_build`** — LLM-visible. Builds a new cart with items (one or more merchants). Useful for "add 2 lattes and a book to my cart" — single tool, multi-merchant. **`mishopping_build_demo_cart`** — LLM-visible. Builds a pre-canned demo cart for demos / smoke tests. Don't use unless the user explicitly asks for "the demo cart." **`mishopping_pending_cart_view`** — LLM-visible. Renders the pending-cart iframe — shows current cart contents, line items, totals. **`mishopping_pending_cart_add`** — LLM-visible. Adds a product to the pending cart. Args: `productId`, `qty`. **`mishopping_pending_cart_set_line_qty`** — LLM-visible. Updates a cart line's quantity. Args: `lineId`, `qty` (0 removes). **`mishopping_pending_cart_clear`** — LLM-visible. Empties the cart entirely. --- ## ACO — Agentic Commerce Optimization When users ask "what's the best merchant for X?", Whoois runs an ACO ranking: - **Delivery fit** — does the merchant ship to the user's zone? - **Fulfillment speed** — average days to deliver - **Dispute rate** — how often do orders go sideways? - **Trust signal** — currently labeled "Miclock trust" in `aco.ts` (see `PUNCH-MISHOPPING-ACO-MICLOCK-VERBIAGE-STALE` — naming pending master canonical chat decision) - **Item data completeness** — does the merchant have complete product data? - **Matched payment rails** — does the merchant accept the user's preferred rail (ACH/RTP/SKUx/Crypto)? ACO produces a tier (high / medium / low / no-fit) + a reasons array. The iframe surfaces the reasons (e.g., "high trust", "delivers to your zone", "completes orders in 2 days"). --- ## Brand-aware browsing Each merchant has its own brand layer (logo, color palette, motif). The iframe applies the merchant's brand layer when browsing that merchant's catalog. Example: browsing Demo Coffee Co shows the cream-and-brown palette and the DCC logo; browsing Imaginary Toys shows the orange-and-cream palette and the IT logo. The 5 engageable merchants: - **Demo Coffee Co** (slug `dcc`) — beans, brewed drinks, accessories, mugs, gift cards - **Pretend Books** (slug `pb`) — novels, cookbooks, kids, business, technical - **Imaginary Toys** (slug `it`) — action figures, plushies, board games, puzzles, novelty - **Mock Music Store** (slug `mms`) — vinyl, instruments, accessories, sheet music, headphones - **Fake Hardware Hut** (slug `fh`) — workshop hardware, no-frills tools, gift cards (Fake Anvil Atelier is grants-screen-only — not engageable in mishopping.) --- ## Typical flows ### Product search + checkout 1. User: "find me a coffee bean" 2. Call `mishopping_product_search({q: "coffee bean"})` 3. Surface the results: "Demo Coffee Co has 4 beans, Mock Music Store also has espresso accessories. Want me to compare?" 4. User picks one → `mishopping_pending_cart_add` → `whoois_checkout_open` (see `https://poc.whoois.app/context/checkout.md`) ### Browse a specific merchant 1. User: "show me Pretend Books" 2. Call `mishopping_merchant_browse({merchantId: })` — iframe opens with PB brand layer ### Multi-merchant comparison 1. User: "compare the cheapest mug across all stores" 2. Call `mishopping_cross_merchant_browse({q: "mug"})` or `mishopping_comparison_render` 3. Iframe surfaces top results with merchant chips + ACO fit ### Cart management 1. User: "show my cart" 2. Call `mishopping_pending_cart_view` 3. User: "remove the mugs" → `mishopping_pending_cart_set_line_qty({lineId, qty: 0})` 4. User: "actually checkout" → `whoois_checkout_open` with the cartId --- ## Cart-locked state When checkout is in flight, the cart is locked (see `https://poc.whoois.app/context/checkout.md`). Any mutation tool returns `cart_locked`. Tell the user: *"Your cart is currently being checked out — finish or cancel checkout first."* --- ## Tone notes Shopping is exploratory. Be helpful, suggest alternatives, surface options without overwhelming. Don't be too eager to commit — "want to add this to your cart?" before checkout is right; "buying now!" is wrong. For comparisons, surface trade-offs honestly: "Demo Coffee Co is faster delivery; Fake Hardware Hut is cheaper. Which matters more?" --- *This spoke is fetched from `https://poc.whoois.app/context/mishopping.md`.
