+## 📝 Bring! Shopping Lists Protocol
+
+OpenClaw manages the Graf family's Bring! shopping lists using the `bring` MCP tools:
+- **`bring_add_item(item_name, specification="", list_name="Einkaufsladen")`**
+- **`bring_add_batch(items=[{"name": "...", "specification": "..."}], list_name="Einkaufsladen")`**
+- **`bring_get_items(list_name="Einkaufsladen")`**
+- **`bring_complete_item(item_name, list_name="Einkaufsladen")`**
+- **`bring_remove_item(item_name, list_name="Einkaufsladen")`**
+- **`bring_list_lists()`**
+
+### 1. List Routing & Defaults
+The family maintains multiple distinct lists in Bring!:
+1. **`Einkaufsladen`** (**Default**): Groceries, supermarket items, drugstore (dm/Rossmann), household staples. Used for all general shopping queries unless another store is explicitly mentioned.
+2. **`Baumarkt`**: Hardware store items, DIY supplies, tools, screws/nails, timber, paint, plumbing, garden supplies.
+3. **`Ikea`**: Furniture, home decor, Swedish food market, home organization items.
+4. **`Gewuerzeinkaufsliste`**: Dedicated list for spices, herbs, and seasonings.
+
+### 2. Interaction Rules
+- **Adding Items**:
+  - *"Pack Milch auf die Einkaufsliste"* -> `bring_add_item(item_name="Milch", list_name="Einkaufsladen")`
+  - *"Schreib 50er Spax Schrauben auf die Baumarkt-Liste"* -> `bring_add_item(item_name="Spax Schrauben", specification="50er", list_name="Baumarkt")`
+  - *"Wir brauchen Koriander und Kardamom"* -> `bring_add_item` with `list_name="Gewuerzeinkaufsliste"` (or `bring_add_batch`)
+  - *"Brauchen neue Kissenbezüge von Ikea"* -> `bring_add_item(item_name="Kissenbezüge", list_name="Ikea")`
+- **Confirmation**:
+  - Always give a concise confirmation with markdown bolding:
+    - *„✅ **Milch** (3.8%) auf die Liste **Einkaufsladen** gesetzt.“*
+    - *„✅ **Spax Schrauben** (50er) auf die Liste **Baumarkt** gesetzt.“*
+- **Reading / Checking**:
+  - When asked *"Was steht auf der Einkaufsliste?"*: call `bring_get_items(list_name="Einkaufsladen")` and summarize the items clearly.
