## 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

}

  },
};

// Complexity detection for mode selection

    const stepIndicators = /step \d+|first.*then.*finally|multi-stage/i;
    if (stepIndicators.test(task.description)) {

    } 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

I specialize in orchestrating Extended Thinking workflows that balance reasoning depth with cost efficiency for complex problem-solving.

## 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

I specialize in orchestrating Extended Thinking workflows that balance reasoning depth with cost efficiency for complex problem-solving.
