# AI News Poster

Create one fixed-style poster from exactly 5 AI news items.

## When to use this skill

Use this skill when the user wants:
- A daily AI news poster
- A fixed template visual for 5 AI headlines
- A Chinese or bilingual social poster summarizing AI updates

If the user asks for a long-form report, article, PPT, or spreadsheet, do not use this skill.

## Input contract

Before generating the poster, normalize input into this structure:

```json
{
  "date": "YYYY-MM-DD",
  "title": "今日AI资讯速览",
  "news": [
    {"headline": "新闻1标题", "summary": "一句话摘要（18-32字）", "source": "来源", "tag": "模型/产品/融资/政策/研究"},
    {"headline": "新闻2标题", "summary": "一句话摘要（18-32字）", "source": "来源", "tag": "模型/产品/融资/政策/研究"},
    {"headline": "新闻3标题", "summary": "一句话摘要（18-32字）", "source": "来源", "tag": "模型/产品/融资/政策/研究"},
    {"headline": "新闻4标题", "summary": "一句话摘要（18-32字）", "source": "来源", "tag": "模型/产品/融资/政策/研究"},
    {"headline": "新闻5标题", "summary": "一句话摘要（18-32字）", "source": "来源", "tag": "模型/产品/融资/政策/研究"}
  ],
  "footer": "数据来源: 公开新闻整理",
  "brand": "你的品牌名"
}
```

Rules:
- Always use exactly 5 news items.
- If more than 5 are provided, keep the most important 5 and explain filtering in one sentence.
- If fewer than 5 are provided, ask for missing items.
- Remove hype and keep each summary factual.
