Reflexion Framework Implementation Strategy

Overview​

This document outlines the detailed implementation strategy for the Reflexion framework, including the Actor-Evaluator-Self-Reflection pattern, memory management systems, and learning workflows for continuous improvement in MCP ADR Analysis Server tools.

Implementation Architecture​

Core Components Implementation​

1. Actor Component​

Purpose: Execute tasks with memory-enhanced context and learning integration

Implementation Approach:

// Pseudo-implementation structure
class ReflexionActor {
  async executeWithMemory(
    task: TaskDefinition,
    context: any,
    memories: ReflexionMemory[]
  ): Promise<TaskAttempt>
}

Actor Responsibilities:

  • Memory Integration: Incorporate relevant past experiences into current task execution
  • Context Enhancement: Enrich task context with lessons learned and strategies
  • Strategy Selection: Choose optimal approaches based on past successes and failures
  • Trajectory Generation: Create detailed execution paths for evaluation and learning

2. Evaluator Component​

Purpose: Assess performance using multiple criteria and generate actionable feedback

Evaluation Criteria Implementation:

Task Success (Weight: 25%)​
  • Metric: Binary success/failure with quality gradations
  • Evaluation: Compare intended vs actual outcomes
  • Scoring: 0-1 scale with partial credit for near-misses
Quality Assessment (Weight: 20%)​
  • Metric: Multi-dimensional quality evaluation
  • Evaluation: Accuracy, completeness, relevance, clarity
  • Scoring: Weighted average of quality dimensions

  • Evaluation: Compare to baseline and previous attempts
  • Scoring: Relative efficiency improvement
Innovation Evaluation (Weight: 10%)​

Memory Persistence Implementation​

// Prompt-driven memory persistence
export async function persistMemoryWithPrompt(memory: ReflexionMemory) {
  const persistencePrompt = `
# Memory Persistence Request

Please save the following Reflexion memory to the appropriate file location.

## Memory Details
- **Memory ID**: ${memory.memoryId}
- **Type**: ${memory.memoryType}
- **Category**: ${memory.metadata.category}
- **Created**: ${memory.createdAt}

## Memory Content
${JSON.stringify(memory.content, null, 2)}

## File Operations Required
1. **Determine File Path**: Based on memory type and category
2. **Create Directory**: If it doesn't exist
3. **Save Memory File**: In JSON format with proper naming
4. **Update Index**: Add entry to memory catalog and relevant indexes
5. **Validate Storage**: Ensure file was saved correctly

## Expected File Structure
- Path: ./reflexion-memory/{type}/{category}/{memoryId}.json
- Index: ./reflexion-memory/indexes/memory-catalog.json
- Backup: Create backup if updating existing memory

Please execute these file operations and confirm successful storage.
`;

  return {
    content: [{ type: 'text', text: persistencePrompt }],
    metadata: {
      operation: 'memory_persistence',
      memoryId: memory.memoryId,
      memoryType: memory.memoryType
    }
  };
}

Learning Workflows​

Workflow 1: Single Task Reflexion​

Duration: 3-5 minutes per task Steps:

  1. Memory Retrieval (30s): Find relevant past experiences
  2. Task Execution (60-180s): Execute with memory-enhanced context
  3. Performance Evaluation (30s): Score outcomes against criteria
  4. Self-Reflection (60s): Generate lessons and insights
  5. Memory Integration (30s): Update memory system

Workflow 2: Continuous Learning Loop​

Duration: Ongoing across multiple tasks Process:

  1. Pattern Detection: Identify recurring themes across attempts
  2. Meta-Learning: Learn about learning effectiveness
  3. Strategy Evolution: Refine approaches based on accumulated evidence
  4. Knowledge Consolidation: Strengthen validated memories, weaken contradicted ones

Workflow 3: Cross-Task Learning Transfer​

Duration: Variable based on task similarity Process:

  1. Similarity Assessment: Identify related task types and contexts
  2. Knowledge Transfer: Apply lessons from one domain to another
  3. Adaptation: Modify strategies for new contexts
  4. Validation: Test transferred knowledge effectiveness

Integration with MCP Tools​

Tool-Specific Learning Patterns​

ADR Generation Tools​

Learning Focus Areas:

  • Context Analysis Accuracy: Learn to better understand project requirements
  • Stakeholder Alignment: Improve ADR relevance and clarity
  • Decision Quality: Learn from ADR adoption and feedback outcomes

Reflexion Pattern:

export async function generateAdrsWithReflexion(context: any) {
  // Step 1: Retrieve relevant memories
  const memories = await retrieveRelevantMemories('adr-generation', context);
  
  // Step 2: Create memory-enhanced prompt
  const enhancedPrompt = await enhancePromptWithMemories(
    createAdrGenerationPrompt(context),
    memories
  );
  
  // Step 3: Execute with reflexion tracking
  const result = await executeWithReflexion(enhancedPrompt, {
    taskType: 'adr-generation',
    evaluationCriteria: ['relevance', 'clarity', 'feasibility', 'completeness'],
    memoryIntegration: true
  });
  
  return result;
}

Analysis Tools​

Learning Focus Areas:

  • Technology Detection: Improve accuracy of technology identification
  • Pattern Recognition: Better identify architectural patterns
  • Context Understanding: Enhanced project context analysis

Research Tools​

Learning Focus Areas:

  • Question Quality: Generate more effective research questions
  • Source Evaluation: Better assess research source quality
  • Synthesis Skills: Improve research integration and synthesis

Memory-Enhanced Prompt Generation​

export async function enhancePromptWithMemories(
  basePrompt: PromptObject,
  memories: ReflexionMemory[]
): Promise<PromptObject> {
  
  const memoryContext = memories.map(memory => ({
    lesson: memory.content.summary,
    applicability: memory.content.applicableScenarios,
    confidence: memory.relevanceScore,
    evidence: memory.content.evidence
  }));

  const enhancedPrompt = `
# Memory-Enhanced Task Execution

## Original Task
${basePrompt.prompt}

## Relevant Past Experiences
${memoryContext.map((mem, index) => `
### Experience ${index + 1} (Confidence: ${mem.confidence})
**Lesson**: ${mem.lesson}
**Applicable to**: ${mem.applicability.join(', ')}
**Evidence**: ${mem.evidence.join('; ')}
`).join('\n')}

## Memory-Informed Approach
Based on past experiences, please:
1. **Apply Relevant Lessons**: Use the lessons learned from similar situations
2. **Avoid Known Pitfalls**: Be aware of common mistakes and failure patterns
3. **Leverage Successful Strategies**: Build on approaches that have worked well
4. **Adapt to Context**: Modify strategies based on current context differences

## Enhanced Instructions
${basePrompt.instructions}

## Success Criteria
- Apply at least 2 relevant lessons from past experiences
- Demonstrate learning from previous mistakes
- Show improvement over baseline approaches
- Generate new insights for future learning

Execute the task with memory-informed decision making and document how past experiences influenced your approach.
`;

  return {
    prompt: enhancedPrompt,
    instructions: basePrompt.instructions,
    context: {
      ...basePrompt.context,
      memoriesUsed: memories.map(m => m.memoryId),
      memoryEnhanced: true
    }
  };
}

Performance Optimization​

Memory Retrieval Optimization​

  • Relevance Scoring: Use context similarity and past success rates
  • Temporal Weighting: Prefer recent memories while preserving valuable old ones
  • Category Filtering: Focus on memories from similar task types
  • Quality Thresholding: Only retrieve high-quality, validated memories

Learning Efficiency​

  • Incremental Updates: Update memories incrementally rather than wholesale replacement
  • Batch Processing: Process multiple related memories together
  • Lazy Loading: Load memories only when needed
  • Compression: Consolidate similar memories to reduce storage and retrieval overhead

Resource Management​

  • Memory Limits: Implement configurable limits on memory storage
  • Cleanup Strategies: Automatic removal of outdated or low-value memories
  • Caching: Cache frequently accessed memories for faster retrieval
  • Indexing: Maintain efficient indexes for fast memory search

This implementation strategy provides a comprehensive roadmap for building the Reflexion framework while maintaining the 100% prompt-driven architecture and ensuring effective learning and memory management across MCP tools.
