## Core Expertise:

### 1. **Thinking Mode Architecture**

**Understanding Thinking Levels:**
```typescript
// Extended Thinking mode definitions
interface ThinkingMode {
  level: 'think' | 'think-hard' | 'ultrathink';
  budgetRange: [number, number]; // [min, max] thinking tokens
  typicalDuration: string;
  costMultiplier: number; // vs standard inference
  idealUseCases: string[];
}

const THINKING_MODES: Record<string, ThinkingMode> = {
  think: {
    level: 'think',
    budgetRange: [1000, 5000],
    typicalDuration: '5-15 seconds',
    costMultiplier: 1.5,
    idealUseCases: [
      'Simple algorithmic problems',
      'Straightforward code reviews',
      'Basic architecture questions',
      'Standard debugging tasks'
    ]
  },
  'think-hard': {
    level: 'think-hard',
    budgetRange: [5000, 20000],
    typicalDuration: '15-60 seconds',
    costMultiplier: 2.5,
    idealUseCases: [
      'Complex refactoring decisions',
      'Multi-step mathematical proofs',
      'Security vulnerability analysis',
      'Performance optimization planning'
    ]
  },
  ultrathink: {
    level: 'ultrathink',
    budgetRange: [20000, 100000],
    typicalDuration: '1-5 minutes',
    costMultiplier: 5.0,
    idealUseCases: [
      'Novel algorithm design',
      'System architecture from scratch',
      'Research paper synthesis',
      'Exhaustive edge case enumeration'
    ]
  }
};

// Complexity detection for mode selection
class ComplexityAnalyzer {
  analyzeTaskComplexity(task: {
    description: string;
    codeContext?: string;
    domainKnowledge?: string;
  }): {
    score: number; // 1-10 complexity scale
    factors: string[];
    recommendedMode: 'think' | 'think-hard' | 'ultrathink';
  } {
    let complexityScore = 1;
    const factors: string[] = [];
    
    // Factor 1: Problem space size
    const problemSpaceIndicators = [
      'all possible', 'exhaustive', 'enumerate', 'comprehensive'
    ];
    if (problemSpaceIndicators.some(ind => task.description.toLowerCase().includes(ind))) {
      complexityScore += 3;
      factors.push('Large problem space requiring exhaustive exploration');
    }
    
    // Factor 2: Multi-step reasoning
    const stepIndicators = /step \d+|first.*then.*finally|multi-stage/i;
    if (stepIndicators.test(task.description)) {
      complexityScore += 2;
      factors.push('Multi-step reasoning required');
    }
    
    // Factor 3: Domain expertise required
    const expertiseIndicators = [
      'security', 'cryptography', 'concurrency', 'distributed systems',
      'formal verification', 'algorithm design'
    ];
    if (expertiseIndicators.some(domain => task.description.toLowerCase().includes(domain))) {
      complexityScore += 2;
      factors.push('Specialized domain knowledge required');
    }
    
    // Factor 4: Code context size
    if (task.codeContext && task.codeContext.length > 10000) {
      complexityScore += 1;
      factors.push('Large codebase context');
    }
    
    // Factor 5: Uncertainty/ambiguity
    const uncertaintyIndicators = ['unknown', 'unclear', 'ambiguous', 'investigate'];
    if (uncertaintyIndicators.some(ind => task.description.toLowerCase().includes(ind))) {
      complexityScore += 1;
      factors.push('High uncertainty requiring exploratory reasoning');
    }
    
    // Map complexity to mode
    let recommendedMode: 'think' | 'think-hard' | 'ultrathink';
    if (complexityScore <= 3) {
      recommendedMode = 'think';
    } else if (complexityScore <= 7) {
      recommendedMode = 'think-hard';
    } else {
      recommendedMode = 'ultrathink';
    }
    
    return { score: complexityScore, factors, recommendedMode };
  }
}
```

**Budget Allocation Strategy:**
```typescript
class ThinkingBudgetManager {
  async allocateBudget(task: {
    complexity: number;
    mode: 'think' | 'think-hard' | 'ultrathink';
    maxCost?: number; // Optional cost ceiling in dollars
  }) {
    const modeConfig = THINKING_MODES[task.mode];
    const [minBudget, maxBudget] = modeConfig.budgetRange;
    
    // Calculate recommended thinking budget
    const budgetRatio = (task.complexity - 1) / 9; // Normalize to 0-1
    const recommendedBudget = Math.floor(
      minBudget + (maxBudget - minBudget) * budgetRatio
    );
    
    // Apply cost ceiling if specified
    let finalBudget = recommendedBudget;
    if (task.maxCost) {
      // Anthropic pricing: $3 input / $15 output per MTok for Sonnet
      // Thinking tokens are input tokens
      const budgetFromCost = (task.maxCost / 3) * 1_000_000;
      finalBudget = Math.min(recommendedBudget, budgetFromCost);
    }
    
    return {
      mode: task.mode,
      thinkingBudget: finalBudget,
      estimatedDuration: this.estimateDuration(task.mode, finalBudget),
      estimatedCost: (finalBudget / 1_000_000) * 3, // Thinking tokens as input
      recommendation: this.generateRecommendation(task.mode, finalBudget, recommendedBudget)
    };
  }
  
  estimateDuration(mode: string, budget: number): string {
    // Rough approximation: ~1000 tokens/second thinking speed
    const seconds = budget / 1000;
    if (seconds < 60) {
      return `~${Math.ceil(seconds)} seconds`;
    }
    return `~${Math.ceil(seconds / 60)} minutes`;
  }
  
  generateRecommendation(mode: string, finalBudget: number, recommendedBudget: number): string {
    if (finalBudget < recommendedBudget * 0.7) {
      return `Budget constrained. Consider increasing maxCost for better results or reducing complexity.`;
    }
    if (mode === 'ultrathink' && finalBudget > 50000) {
      return `High thinking budget allocated. Ensure task truly requires exhaustive reasoning to justify cost.`;
    }
    return `Budget allocation optimal for ${mode} mode.`;
  }
}
```

### 2. **Multi-Stage Reasoning Workflows**

**Progressive Complexity Escalation:**
```typescript
class ProgressiveThinkingOrchestrator {
  async executeProgressive(task: {
    description: string;
    maxBudget: number; // Total budget across all stages
    stages?: number; // Number of escalation stages (default 3)
  }) {
    const stages = task.stages || 3;
    const budgetPerStage = task.maxBudget / stages;
    
    const results = [];
    let currentMode: 'think' | 'think-hard' | 'ultrathink' = 'think';
    
    for (let stage = 1; stage <= stages; stage++) {
      console.log(`Stage ${stage}/${stages}: Running ${currentMode} mode`);
      
      const stageResult = await this.executeThinkingStage({
        task: task.description,
        mode: currentMode,
        budget: budgetPerStage,
        context: results.length > 0 ? results[results.length - 1].output : undefined
      });
      
      results.push(stageResult);
      
      // Check if we need to escalate
      if (this.shouldEscalate(stageResult)) {
        currentMode = this.escalateMode(currentMode);
        console.log(`Escalating to ${currentMode} due to: ${stageResult.escalationReason}`);
      } else {
        // Task solved, no need for more stages
        console.log(`Task solved at stage ${stage}, skipping remaining stages`);
        break;
      }
    }
    
    return {
      stages: results.length,
      finalMode: currentMode,
      totalThinkingTokens: results.reduce((sum, r) => sum + r.thinkingTokens, 0),
      totalCost: results.reduce((sum, r) => sum + r.cost, 0),
      solution: results[results.length - 1].output,
      thinkingEvolution: results.map(r => ({
        mode: r.mode,
        tokens: r.thinkingTokens,
        confidence: r.confidence
      }))
    };
  }
  
  shouldEscalate(stageResult: any): boolean {
    return (
      stageResult.confidence < 0.8 || // Low confidence
      stageResult.output.includes('need more thinking') ||
      stageResult.output.includes('uncertain') ||
      stageResult.thinkingTokens >= stageResult.budget * 0.95 // Hit budget ceiling
    );
  }
  
  escalateMode(currentMode: string): 'think' | 'think-hard' | 'ultrathink' {
    const escalationPath = ['think', 'think-hard', 'ultrathink'];
    const currentIndex = escalationPath.indexOf(currentMode);
    return (escalationPath[currentIndex + 1] || 'ultrathink') as any;
  }
}
```

### 3. **Thinking Timeout and Recovery**

**Budget Exhaustion Handling:**
```typescript
class ThinkingRecoveryManager {
  async handleThinkingTimeout(options: {
    task: string;
    mode: string;
    budgetUsed: number;
    budgetLimit: number;
    partialOutput?: string;
  }) {
    const exhaustionReason = this.diagnoseExhaustion(options);
    
    const recoveryStrategies = [
      {
        strategy: 'increase_budget',
        description: 'Increase thinking budget by 2x and retry',
        newBudget: options.budgetLimit * 2,
        likelySolution: exhaustionReason === 'legitimate_complexity'
      },
      {
        strategy: 'simplify_task',
        description: 'Break task into smaller sub-tasks',
        subtasks: this.decomposeTask(options.task),
        likelySolution: exhaustionReason === 'task_too_broad'
      },
      {
        strategy: 'downgrade_mode',
        description: 'Switch to faster mode with multiple iterations',
        newMode: this.downgradeMode(options.mode),
        iterations: 3,
        likelySolution: exhaustionReason === 'wrong_mode'
      },
      {
        strategy: 'use_partial',
        description: 'Use partial thinking output as starting point',
        continueFrom: options.partialOutput,
        likelySolution: exhaustionReason === 'nearly_complete'
      }
    ];
    
    const recommended = recoveryStrategies.find(s => s.likelySolution);
    
    return {
      exhaustionReason,
      recommendedStrategy: recommended,
      allStrategies: recoveryStrategies,
      autoRecovery: this.shouldAutoRecover(exhaustionReason)
    };
  }
  
  diagnoseExhaustion(options: any): string {
    const utilization = options.budgetUsed / options.budgetLimit;
    
    if (utilization >= 0.98) {
      if (options.partialOutput && options.partialOutput.length > 1000) {
        return 'nearly_complete'; // Got close to solution
      }
      return 'legitimate_complexity'; // Task genuinely complex
    }
    
    if (utilization < 0.5) {
      return 'wrong_mode'; // Mode mismatch, should use faster mode
    }
    
    if (options.task.split('.').length > 5) {
      return 'task_too_broad'; // Task needs decomposition
    }
    
    return 'unknown';
  }
  
  decomposeTask(task: string): string[] {
    // Simple heuristic: split on sentence boundaries
    const sentences = task.split(/[.!?]+/).filter(s => s.trim().length > 10);
    
    if (sentences.length <= 2) {
      return [task]; // Can't decompose further
    }
    
    // Group into 3 sub-tasks
    const chunkSize = Math.ceil(sentences.length / 3);
    const subtasks = [];
    for (let i = 0; i < sentences.length; i += chunkSize) {
      subtasks.push(sentences.slice(i, i + chunkSize).join('. ') + '.');
    }
    
    return subtasks;
  }
}
```

### 4. **Thinking Budget ROI Analysis**

**Performance Tracking:**
```typescript
class ThinkingPerformanceTracker {
  trackThinkingSession(session: {
    taskId: string;
    mode: string;
    budgetAllocated: number;
    budgetUsed: number;
    timeElapsed: number; // milliseconds
    solutionQuality: number; // 1-10 user rating
    cost: number;
  }) {
    const efficiency = {
      budgetUtilization: (session.budgetUsed / session.budgetAllocated) * 100,
      costPerQualityPoint: session.cost / session.solutionQuality,
      tokensPerSecond: session.budgetUsed / (session.timeElapsed / 1000),
      roi: (session.solutionQuality * 10) / session.cost // Quality value per dollar
    };
    
    // Store metrics for future optimization
    this.storeMetrics({
      taskId: session.taskId,
      mode: session.mode,
      ...efficiency,
      timestamp: new Date().toISOString()
    });
    
    return efficiency;
  }
  
  async getThinkingRecommendations(historicalData: any[]) {
    // Analyze historical performance
    const byMode = this.groupByMode(historicalData);
    
    const insights = [];
    
    for (const [mode, sessions] of Object.entries(byMode)) {
      const avgROI = this.average(sessions.map((s: any) => s.roi));
      const avgUtilization = this.average(sessions.map((s: any) => s.budgetUtilization));
      
      if (avgUtilization < 60) {
        insights.push({
          mode,
          issue: 'Budget over-allocated',
          recommendation: `Reduce ${mode} budget by 30% based on historical usage`,
          potentialSavings: this.calculateSavings(sessions, 0.3)
        });
      }
      
      if (avgROI < 5) {
        insights.push({
          mode,
          issue: 'Low ROI for thinking investment',
          recommendation: `Consider downgrading to faster mode or improving task decomposition`,
          alternativeMode: this.suggestAlternative(mode)
        });
      }
    }
    
    return insights;
  }
}
```

## Extended Thinking Best Practices:

1. **Mode Selection**: Start with 'think', escalate only if needed
2. **Budget Allocation**: Allocate 1.5x expected based on complexity
3. **Progressive Reasoning**: Use multi-stage for unknown complexity
4. **Cost Control**: Set maxCost budgets to prevent runaway thinking
5. **Recovery Planning**: Have timeout recovery strategies ready
6. **ROI Tracking**: Measure quality vs cost to optimize future allocations
7. **Task Decomposition**: Break complex tasks into thinkable chunks
8. **Partial Outputs**: Use incomplete thinking as context for retry

## When to Use Each Mode:

**Think (1k-5k tokens, ~5-15 sec):**
- Simple algorithm implementation
- Code review with obvious issues
- Straightforward debugging
- Quick architectural questions

**Think Hard (5k-20k tokens, ~15-60 sec):**
- Complex refactoring decisions
- Security vulnerability analysis
- Multi-step optimization planning
- Non-trivial algorithm design

**Ultrathink (20k-100k tokens, ~1-5 min):**
- Novel system architecture
- Exhaustive edge case enumeration
- Research synthesis and hypothesis generation
- Formal verification or proof construction
