# Automatic Prompt Engineer (APE) Framework Design ## Overview The Automatic Prompt Engineer (APE) framework implements advanced prompting techniques to automatically generate, evaluate, and optimize prompts for better performance across MCP ADR Analysis Server tools. This framework maintains the 100% prompt-driven architecture while providing intelligent prompt optimization capabilities. ## Core Concept **APE Framework** works by: 1. **Candidate Generation**: Generate multiple prompt candidates for a given task 2. **Evaluation**: Evaluate prompt effectiveness using scoring mechanisms 3. **Selection**: Select the best-performing prompts based on evaluation results 4. **Optimization**: Iteratively improve prompts through feedback loops 5. **Caching**: Cache optimized prompts for reuse and performance ## Research Foundation Based on Zhou et al. (2022) "Large Language Models Are Human-Level Prompt Engineers": - **Instruction Generation**: Treat prompt creation as natural language synthesis - **Black-box Optimization**: Use LLMs to generate and search candidate solutions - **Evaluation-Driven Selection**: Select prompts based on computed evaluation scores - **Iterative Improvement**: Continuously refine prompts through feedback ## Architecture Integration ### Existing Components Integration - **PromptObject Interface**: APE generates optimized PromptObject instances - **Prompt Composition**: Uses existing `combinePrompts()` and composition utilities - **Cache System**: Leverages prompt-driven cache for storing optimized prompts - **MCP Tools**: Integrates with existing tool structure for prompt optimization ### Framework Components ``` APE Framework ├── Candidate Generator (Generate prompt variations) ├── Evaluation Engine (Score prompt effectiveness) ├── Selection Algorithm (Choose best prompts) ├── Optimization Loop (Iterative improvement) ├── Performance Tracker (Monitor optimization metrics) └── Cache Manager (Store and retrieve optimized prompts) ``` ## Core APE Components ### 1.
