Reflection Mechanisms and Metacognition

Overview

Reflection in agentic systems is the ability to examine one's own thinking process, evaluate decisions, and learn from internal states. Metacognition — thinking about thinking — enables agents to monitor and regulate their own cognitive processes.

Levels of Reflection

1. Task-Level Reflection

Post-Task Analysis

typescript
interface TaskReflection {
  async reflectOnTask(execution: Execution): Promise<Reflection> {
    return {
      // What was accomplished?
      outcome: this.analyzeOutcome(execution),
      
      // How well was it done?
      quality: this.assessQuality(execution),
      
      // What could be improved?
      improvements: this.identifyImprovements(execution),
      
      // What was learned?
      learnings: this.extractLearnings(execution)
    };
  }
}

During-Task Monitoring

typescript
interface MonitoringReflection {
  async monitorExecution(execution: Execution): Promise<void> {
    // Check progress
    const progress = this.assessProgress(execution);
    
    // Detect issues early
    const issues = this.detectPotentialIssues(execution);
    
    if (issues.length > 0) {
      // Reflect on whether to continue or adjust
      const decision = await this.reflectOnIssues(issues);
      
      if (decision.shouldAdjust) {
        await this.adjustApproach(execution, decision.adjustments);
      }
    }
  }
}

2. Strategy-Level Reflection

Approach Evaluation

typescript
interface StrategyReflection {
  async reflectOnStrategy(
    strategy: Strategy,
    outcomes: Outcome[]
  ): Promise<StrategyAssessment> {
    return {
      // Is this strategy effective?
      effectiveness: this.calculateEffectiveness(outcomes),
      
      // When does it work best?
      applicability: this.determineApplicability(outcomes),
      
      // What are its limitations?
      limitations: this.identifyLimitations(strategy, outcomes),
      
      // How could it be improved?
      enhancements: this.suggestEnhancements(strategy, outcomes)
    };
  }
}

Alternative Strategy Generation

typescript
interface AlternativeGenerator {
  async generateAlternatives(
    currentStrategy: Strategy,
    reflection: Reflection
  ): Promise<Strategy[]> {
    // Based on limitations, generate alternatives
    const alternatives = [];
    
    for (const limitation of reflection.limitations) {
      const alternativesForLimitation = 
        await this.generateAlternativesFor(limitation);
      alternatives.push(...alternativesForLimitation);
    }
    
    // Evaluate each alternative
    return Promise.all(
      alternatives.map(async alt => ({
        strategy: alt,
        potential: await this.estimatePotential(alt),
        risk: await this.estimateRisk(alt)
      }))
    );
  }
}

3. Meta-Level Reflection

Reflection on Reflection

typescript
interface MetaReflection {
  async reflectOnReflection(
    reflection: Reflection
  ): Promise<MetaReflection> {
    return {
      // Was the reflection accurate?
      accuracy: this.assessReflectionAccuracy(reflection),
      
      // Was it comprehensive?
      completeness: this.assessCompleteness(reflection),
      
      // Did it lead to improvement?
      usefulness: this.assessUsefulness(reflection),
      
      // How to improve reflection?
      reflectionImprovements: this.suggestReflectionImprovements(reflection)
    };
  }
}

Reflection Triggers

1. Event-Based Triggers

typescript
interface ReflectionTriggers {
  // Trigger on success
  onSuccess: (execution: Execution) => {
    return {
      whatWorked: analyzeSuccessFactors(execution),
      canGeneralize: checkGeneralizability(execution)
    };
  };
  
  // Trigger on failure
  onFailure: (execution: Execution) => {
    return {
      rootCause: analyzeRootCause(execution),
      prevention: suggestPrevention(execution)
    };
  };
  
  // Trigger on anomaly
  onAnomaly: (execution: Execution, baseline: Baseline) => {
    return {
      deviation: calculateDeviation(execution, baseline),
      explanation: generateExplanation(execution, baseline)
    };
  };
}

2. Temporal Triggers

typescript
interface TemporalReflection {
  // Periodic reflection
  async scheduledReflection(): Promise<void> {
    const recentActivity = await this.getRecentActivity();
    
    const patterns = await this.identifyPatterns(recentActivity);
    
    for (const pattern of patterns) {
      await this.reflectOnPattern(pattern);
    }
  }
  
  // Milestone reflection
  async milestoneReflection(milestone: Milestone): Promise<void> {
    const phaseActivity = await this.getPhaseActivity(milestone);
    
    return {
      phaseReview: this.reviewPhase(phaseActivity),
      transitionReadiness: this.assessTransitionReadiness(phaseActivity),
      lessonsForNextPhase: this.extractLessons(phaseActivity)
    };
  }
}

3. Threshold-Based Triggers

typescript
interface ThresholdReflection {
  thresholds: {
    errorRate: 0.1;        // Reflect if error rate > 10%
    costIncrease: 1.5;     // Reflect if cost 1.5x baseline
    timeOverrun: 2.0;      // Reflect if 2x estimated time
    qualityDrop: 0.8;      // Reflect if quality < 80% baseline
  };
  
  async checkThresholds(metrics: Metrics): Promise<boolean> {
    for (const [metric, threshold] of Object.entries(this.thresholds)) {
      if (metrics[metric] > threshold) {
        await this.triggerReflection(metric, metrics[metric]);
        return true;
      }
    }
    return false;
  }
}

Reflection Techniques

1. Structured Self-Questioning

typescript
interface StructuredReflection {
  questions = [
    "What was I trying to accomplish?",
    "What approach did I take?",
    "What was the outcome?",
    "What worked well?",
    "What didn't work?",
    "What would I do differently?",
    "What patterns do I notice?",
    "How can I improve next time?"
  ];
  
  async answerQuestions(execution: Execution): Promise<Answers> {
    const answers = {};
    
    for (const question of this.questions) {
      answers[question] = await this.answer(
        question,
        execution.context
      );
    }
    
    return answers;
  }
}

2. Counterfactual Reasoning

typescript
interface CounterfactualReasoning {
  async whatIfAnalysis(
    execution: Execution,
    alternative: Alternative
  ): Promise<Counterfactual> {
    return {
      // What would have happened if...
      predictedOutcome: await this.simulateAlternative(
        execution,
        alternative
      ),
      
      // Would it have been better?
      comparison: this.compareOutcomes(
        execution.outcome,
        predictedOutcome
      ),
      
      // When should I use this alternative?
      applicability: this.determineApplicability(alternative)
    };
  }
}

3. Comparative Reflection

typescript
interface ComparativeReflection {
  async compareWithOthers(
    myExecution: Execution,
    similarExecutions: Execution[]
  ): Promise<Comparison> {
    return {
      // How did I do relative to others?
      percentile: this.calculatePercentile(myExecution, similarExecutions),
      
      // What did others do differently?
      differences: this.identifyDifferences(myExecution, similarExecutions),
      
      // What can I learn from top performers?
      bestPractices: this.extractBestPractices(similarExecutions)
    };
  }
}

Reflection Integration

1. Into Knowledge Base

typescript
interface ReflectionIntegration {
  async integrateReflection(reflection: Reflection): Promise<void> {
    // Extract reusable knowledge
    const knowledge = this.extractKnowledge(reflection);
    
    // Update strategy preferences
    await this.updateStrategies(knowledge.strategies);
    
    // Update heuristics
    await this.updateHeuristics(knowledge.heuristics);
    
    // Update mental models
    await this.updateMentalModels(knowledge.models);
  }
}

2. Into Planning

typescript
interface PlanningIntegration {
  async incorporateReflections(task: Task): Promise<Plan> {
    // Get relevant past reflections
    const relevantReflections = await this.findRelevantReflections(task);
    
    // Apply lessons to planning
    const plan = await this.createPlan(task);
    
    for (const reflection of relevantReflections) {
      plan = this.applyLessons(plan, reflection);
    }
    
    return plan;
  }
}

3. Into Execution

typescript
interface ExecutionIntegration {
  async reflectDuringExecution(execution: Execution): Promise<Adjustments> {
    // Continuous micro-reflection
    const microReflection = await this.microReflect(execution);
    
    if (microReflection.concerns.length > 0) {
      // Make real-time adjustments
      return this.generateAdjustments(
        execution,
        microReflection.concerns
      );
    }
    
    return [];
  }
}

Metacognitive Capabilities

  async calibrateConfidence(
    prediction: Prediction,
    outcome: Outcome
  ): Promise<void> {
    const actualConfidence = this.calculateActualConfidence(prediction, outcome);
    const statedConfidence = prediction.confidence;
    
    // Update calibration model
    await this.updateCalibration(
      statedConfidence,
      actualConfidence
    );
    
    // Learn when I'm over/under confident
    await this.learnConfidencePatterns(prediction, outcome);
  }
}

2. Knowledge Boundary Awareness

typescript
interface KnowledgeBoundaries {
  async assessKnowledgeBoundary(
    question: Question
  ): Promise<BoundaryAssessment> {
    return {
      // What do I know?
      known: this.identifyKnownAspects(question),
      
      // What am I uncertain about?
      uncertain: this.identifyUncertainAspects(question),
      
      // What do I not know?
      unknown: this.identifyUnknownAspects(question),
      
      // Should I proceed or seek help?
      recommendation: this.generateRecommendation(known, uncertain, unknown)
    };
  }
}

3. Cognitive Bias Detection

typescript
interface BiasDetection {
  biases = [
    'recency_bias',
    'confirmation_bias',
    'availability_bias',
    'anchoring_bias'
  ];
  
  async detectBiases(decision: Decision): Promise<DetectedBiases> {
    const detected = [];
    
    for (const bias of this.biases) {
      const evidence = await this.checkForBias(decision, bias);
      if (evidence.present) {
        detected.push({ bias, evidence });
      }
    }
    
    return {
      detected,
      mitigation: this.suggestMitigations(detected)
    };
  }
}

Measuring Reflection Quality

Reflection Metrics

typescript
interface ReflectionMetrics {
  // Accuracy
  predictionAccuracy: number;       // Did predictions match reality?
  rootCauseAccuracy: number;        // Correctly identified causes?
  
  // Depth
  analysisDepth: number;            // Surface vs deep analysis
  considerationOfAlternatives: number; // How many alternatives?
  
  // Utility
  actionability: number;            % of reflections leading to action
  improvementRate: number;          // Performance improvement after reflection
  
  // Efficiency
  reflectionTime: number;           // Time spent reflecting
  reflectionCost: number;           // Resources used
}

Reflection Validation

typescript
interface ReflectionValidator {
  async validateReflection(reflection: Reflection): Promise<Validation> {
    // Check against outcomes
    const outcomeValidation = await this.checkAgainstOutcomes(reflection);
    
    // Check for consistency
    const consistencyCheck = await this.checkConsistency(reflection);
    
    // Check for completeness
    const completenessCheck = await this.checkCompleteness(reflection);
    
    return {
      valid: outcomeValidation.valid && 
             consistencyCheck.valid && 
             completenessCheck.valid,
      issues: [...outcomeValidation.issues, 
               ...consistencyCheck.issues,
               ...completenessCheck.issues]
    };
  }
}

Open Questions

  • How deep should reflection go? (Task vs strategy vs meta)
  • What's the cost-benefit of reflection time?
  • How to prevent reflection paralysis?
  • When is real-time reflection worth the overhead?
  • How to validate that reflections are accurate?
