  "name": "Patent Translator",
  "description": "Expert patent translator",
  "domain": "IP",
  "version": "1.0",

}
```
❌ Hard to read in text editor  
❌ Escaped newlines  
❌ Technical syntax  

### After: Markdown Format
```markdown
---
name: "Patent Translator"
description: "Expert patent translator"
domain: "IP"
version: "1.0"
---

# Patent Translation
