- Worker Agent abstract Ch1.3
Design guidance
- SHOULD record load, historical accuracy and cost metadata so selectors can trade them off at runtime.
- SHOULD be kept accurate so primitive/abstract task classification reflects actual agent abilities.
Classification
- Technologies
- A2A Agent Cards
- Quality attributes
- Flexibility (ISO/IEC 25010)Maintainability (ISO/IEC 25010)
- Risks mitigated
- Hardcoded agent routing
