⚠️ 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#

1. 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
2. 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
3. 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）：

json

{
  "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#

1. 与用户对话：使用用户的语言（中文用户用中文回复）
2. 与底层模型交互：始终使用英文
3. 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#

text

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）#

python

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},
    "key_features": [
      {"value": "feature 1", "confidence": 88},
      {"value": "feature 2", "confidence": 75}
    ]
  },
  "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}

📝 Veo 3.1 提示词构建（置信度过滤）#

🎬 分镜脚本 Prompt（保护产品外观）#

python

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
