## Story Statement
|
|
As the Directus Task Management system, I need a sophisticated prompt engineering system that manages prompt templates, optimizes prompts for different AI models, enables dynamic prompt composition, and provides A/B testing capabilities so that AI interactions are consistent, effective, and continuously improving.
|
|
|
|
## Acceptance Criteria
|
|
1. [ ] Prompt template system supports variables and conditional logic
|
|
2. [ ] Template versioning tracks changes and performance metrics
|
|
3. [ ] Dynamic prompt composition handles complex multi-part prompts
|
|
4. [ ] Model-specific optimization for GPT-4, Claude, and other models
|
|
5. [ ] A/B testing framework measures prompt effectiveness
|
|
6. [ ] Prompt library includes 20+ pre-built templates for common tasks
|
|
7. [ ] Template validation ensures proper structure and syntax
|
|
8. [ ] Performance metrics track token usage and response quality
|
|
9. [ ] Template inheritance enables prompt composition and reuse
|
|
10. [ ] Unit tests achieve 80% coverage for prompt components
