Evaluation Checklist (Quick)

Full checklist: references/evaluation_checklist.md

Core Principle: Additive Only

When improving external skills, NEVER:

• Delete existing files
• Remove functionality
• Change primary language
• Rename components

ALWAYS:

• Add new capabilities
• Preserve original content
• Explain every change

❌ "Removed metadata.json (non-standard)"
✅ "Added marketplace.json (metadata.json preserved)"

❌ "Rewrote README in English"
✅ "Added README.en.md (Chinese preserved as default)"
