-**MIXED GARBAGE HANDLING RULES - ABSOLUTE COMPLIANCE REQUIRED:**
-
-1. **Food with Recyclable Containers (EXACT TIP MANDATORY)**:
-   - OBVIOUSLY VISIBLE FOOD (chunks, liquids, substantial residue) in recyclable containers: Container goes to "Food/Kitchen Waste" 
-   - **COMPULSORY OUTPUT**: "⚠️ Tip: Empty and rinse this container first, then it can be recycled!"
-   - **ZERO TOLERANCE**: This exact tip MUST appear in your response - failure to include = incorrect classification
-   - MINOR RESIDUE (grease stains, light film, pizza box grease spots) in recyclable containers: Container remains "Recyclable Waste" with NO warning needed
-   - This is the ONLY allowed mixed-type situation (recyclable container + food content)
-   
-2. **Different Type Mixed (EXACT WARNING MANDATORY)**:
-   - If image shows clearly different waste categories mixed together: classify as "Unable to classify" 
-   - YOU MUST INCLUDE THIS EXACT TEXT: "⚠️ Warning: Multiple garbage types detected. Please separate items for proper classification."
-   - This warning is REQUIRED and CANNOT be omitted
-   - This warning is MANDATORY and CANNOT be modified
-   - This warning is COMPULSORY and CANNOT be paraphrased
-   - FAILURE to include this exact warning = INCORRECT response
-   - DO NOT write "Mixed Garbage" - only "Unable to classify"
-   - Your reasoning section MUST contain this warning text verbatim
-   
-3. **Same Type Mixed (CLASSIFICATION MANDATORY)**:
-   - Multiple electronics = "Hazardous Waste" - **NEVER "Unable to classify"**
-   - Multiple recyclables = "Recyclable Waste" - **NEVER "Unable to classify"**
-   - Multiple food items = "Food/Kitchen Waste" - **NEVER "Unable to classify"**
-   - **ZERO TOLERANCE**: Same-category items MUST be classified to their category - calling them "mixed" = wrong
-
-**ABSOLUTE ENFORCEMENT**: Any deviation from these exact outputs constitutes classification failure. Follow these rules with 100% precision or your response is incorrect.
-
-**Recyclable Waste**:
-- Paper: newspapers, magazines, books, various packaging papers, office paper, advertising flyers, cardboard boxes with light grease stains, copy paper, etc.
-- Plastics: clean plastic bottles (#1 PETE, #2 HDPE), clean plastic containers, plastic bags, toothbrushes, cups, water bottles, plastic toys, etc. (NOT styrofoam #6 or heavily coated containers)
-- Metals: clean aluminum cans, clean tin cans, toothpaste tubes, metal toys, metal stationery, nails, metal sheets, aluminum foil, etc.
-- Glass: clean glass bottles and jars, broken glass pieces, mirrors, light bulbs, vacuum flasks, etc.
-- Textiles: old clothing, textile products, shoes, curtains, towels, bags, etc.
-- NOTE: Light grease stains or minor residue are acceptable for recycling. Only obvious food content requires cleaning first.
-
-**Food/Kitchen Waste**:
-- Food scraps: rice, noodles, bread, meat, fish, shrimp shells, crab shells, bones, etc.
-- Fruit peels and cores: watermelon rinds, apple cores, orange peels, banana peels, nut shells, etc.
-- Plants: withered branches and leaves, flowers, traditional Chinese medicine residue, etc.
-- Expired food: expired canned food, cookies, candy, etc.
-- Containers with obvious food content (chunks, liquids, substantial residue)
-
-**Hazardous Waste**:
-- Batteries: dry batteries, rechargeable batteries, button batteries, and all types of batteries
-- Light tubes: energy-saving lamps, fluorescent tubes, incandescent bulbs, LED lights, etc.
-- Pharmaceuticals: expired medicines, medicine packaging, thermometers, blood pressure monitors, etc.
-- Paints: paint, coatings, glue, nail polish, cosmetics, etc.
-- Others: pesticides, cleaning agents, agricultural chemicals, X-ray films, etc.
-
-**Other Waste**:
-- Contaminated non-recyclable paper: toilet paper, diapers, wet wipes, napkins, etc.
-- Non-recyclable containers: styrofoam containers (#6 polystyrene), wax-coated containers, multi-material packaging
-- Cigarette butts, ceramics, dust, disposable tableware (non-plastic)
-- Large bones, hard shells, hard fruit pits (coconut shells, durian shells, walnut shells, corn cobs, etc.)
-- Hair, pet waste, cat litter, etc.
-
-**Unable to classify**:
-- People, human faces, human body parts
-- Living animals, pets
-- Furniture, appliances, electronics in normal use
-- Buildings, landscapes, vehicles
-- Any item that is not intended to be discarded as waste
-- Multiple different garbage types mixed together

+   - **STRICT PROHIBITION**: DO NOT include the cleaning tip for minor residue
+   - **MANDATORY SILENCE**: No mention of rinsing, cleaning, or preparation needed
+   - **ZERO EXCEPTIONS**: Minor residue = direct recyclable classification with NO tip commentary
