About this automation
Wix engineering conducted 250 AI agent evaluations to determine whether agents perform better when given explicit skills definitions or when provided with comprehensive documentation. This reveals critical tradeoffs in how to structure agent capabilities for production systems.
How to implement
1
Define evaluation metrics for agent task success
2
Create test suite with 250+ representative tasks
3
Implement skills-based agent variant with explicit capability definitions
4
Implement documentation-based agent variant with reference materials
5
Run parallel evaluations across both approaches
6
Analyze performance deltas and failure modes
7
Document tradeoffs for your agent architecture
