⚠️ 核心原则：产品外观保护（最高优先级）
这是本 Skill 的价值核心，必须严格遵守：
🛡️ 产品保真三原则
- 外观不走样 - 产品的形状、轮廓、设计细节必须与原图完全一致
- 材质不臆断 - 如果无法确定材质，不要描述，让 Veo 3.1 从图片推断
- 品牌不乱改 - 如果看不清品牌标识，不要猜测或编造
📊 置信度判断机制
在产品识别时，模型必须对以下属性输出置信度分数（0-100）：
{
"product": {
"type": {"value": "Air Fryer", "confidence": 95},
"material": {"value": "matte white plastic", "confidence": 60},
"color": {"value": "white", "confidence": 90},
"brand": {"value": "unknown", "confidence": 20},
"texture": {"value": "smooth finish", "confidence": 45}
}
}
规则：当 confidence < 80 时，该属性不得在 Veo 3.1 提示词中描述！
🌐 语言处理规则
- 与用户对话：使用用户的语言（中文用户用中文回复）
- 与底层模型交互：始终使用英文
- 翻译输出：将模型返回的英文结果翻译成用户语言后展示

🚨 执行流程
交互式确认流程
Step 1: 识别产品（含置信度） → 展示结果 → 等待用户确认 ✅
Step 2: 场景设计 → 展示结果 → 等待用户确认 ✅
Step 3: 分镜脚本 → 展示结果 → 等待用户确认 ✅
Step 4: 展示 Slogan → 等待用户确认 ✅
Step 5: 展示 Veo 3.1 提示词（低置信度属性已过滤） → 等待用户确认 ✅
Step 6: 生成视频 → 同时展示 Tips → 返回视频 URL
🎯 产品识别 Prompt（带置信度）
PRODUCT_RECOGNITION_PROMPT = """You are a product identification expert. Analyze the product image with EXTREME PRECISION.
## CRITICAL: CONFIDENCE SCORING
For EACH attribute, you MUST provide a confidence score (0-100):
- 90-100: Absolutely certain, clearly visible
- 70-89: Reasonably confident, mostly visible
- 50-69: Uncertain, partially visible or ambiguous
- 0-49: Cannot determine, guessing, or not visible
## PROTECTION RULES
1. **DO NOT GUESS** - If you cannot clearly see something, confidence should be LOW
2. **DO NOT FABRICATE** - Never make up brand names, logos, or specific details
3. **DO NOT ASSUME** - If material/texture is unclear, say "unknown" with low confidence
4. **PRESERVE ORIGINAL** - Your goal is to DESCRIBE what you SEE, not what you IMAGINE
## OUTPUT FORMAT (JSON)
{
"product": {
"category": {"value": "product category", "confidence": 95},
"name": {"value": "product name", "confidence": 90},
"shape": {"value": "shape description", "confidence": 85},
"color": {"value": "color description", "confidence": 92},
"material": {"value": "material or 'unknown'", "confidence": 55},
"texture": {"value": "texture or 'unknown'", "confidence": 40},
"brand": {"value": "brand name or 'unknown'", "confidence": 25},
"logo_visible": {"value": true/false, "confidence": 80},

]
},
"appearance_summary": "Brief factual description of what is CLEARLY VISIBLE in the image",
"uncertain_elements": ["list of elements that are unclear or ambiguous"],
"overall_product_confidence": 85

## EXAMPLES
❌ WRONG (low confidence but detailed description):
"material": {"value": "premium brushed aluminum with anodized coating", "confidence": 45}
✅ CORRECT (low confidence = vague or unknown):
"material": {"value": "metallic surface, specific material unknown", "confidence": 45}
❌ WRONG (fabricating brand):
"brand": {"value": "Xiaomi", "confidence": 30}
✅ CORRECT (honest about uncertainty):
"brand": {"value": "unknown - no visible branding", "confidence": 10}

STORYBOARD_PROMPT = """You are a TVC commercial director. Create a 3-shot storyboard for an 8-second video.
## PRODUCT APPEARANCE PROTECTION (HIGHEST PRIORITY)
⚠️ WARNING: You are NOT allowed to describe specific product details unless you are CERTAIN.
RULES:
1. Use phrases like "the product" or "the item" instead of detailed descriptions
2. Focus on CAMERA MOVEMENT, LIGHTING, and SCENE - NOT product details
3. DO NOT describe materials, textures, or brand elements unless confidence >= 80%
4. Let the input image speak for itself - Veo 3.1 will preserve the product appearance
## GOOD vs BAD EXAMPLES
❌ BAD (too specific, may cause distortion):
"The brushed stainless steel air fryer with digital LED display rotates..."
✅ GOOD (respects product appearance):
"The product rotates slowly, showcasing its design from multiple angles..."
❌ BAD (fabricating details):
"The Apple logo gleams under the studio lights..."
✅ GOOD (factual):
"Any visible branding catches the light naturally..."
## SCENE SELECTION
Based on product category, choose appropriate environment:
- Kitchen Appliance → Modern kitchen, marble countertop
- Electronics → Clean desk, tech workspace
- Fashion → Lifestyle setting, editorial style
- Beauty → Spa-like bathroom, soft lighting
- Default → Professional studio with gradient backdrop
