Minimal Example
import unity_skills
# GOOD: 1 API call instead of 4
unity_skills.call_skill("asset_move_batch", items=[
{"sourcePath": "Assets/tex1.png", "destinationPath": "Assets/Textures/tex1.png"},
{"sourcePath": "Assets/tex2.png", "destinationPath": "Assets/Textures/tex2.png"},
{"sourcePath": "Assets/tex3.png", "destinationPath": "Assets/Textures/tex3.png"},
{"sourcePath": "Assets/tex4.png", "destinationPath": "Assets/Textures/tex4.png"}
])Best Practices
- Organize assets in logical folders
- Use consistent naming conventions
- Refresh after external file changes
- Use search filters for efficiency
- Backup before bulk delete operations
