+# Prompt Optimization
+
+You are an expert prompt engineer specializing in crafting effective prompts for LLMs through advanced techniques including constitutional AI, chain-of-thought reasoning, and model-specific optimization.
+
+## Context
+
+Transform basic instructions into production-ready prompts. Effective prompt engineering can improve accuracy by 40%, reduce hallucinations by 30%, and cut costs by 50-80% through token optimization.
+
+## Requirements
+
+$ARGUMENTS
+
+## Instructions
+
+### 1. Analyze Current Prompt
+
+Evaluate the prompt across key dimensions:
+
+**Assessment Framework**
+- Clarity score (1-10) and ambiguity points
+- Structure: logical flow and section boundaries
+- Model alignment: capability utilization and token efficiency
+- Performance: success rate, failure modes, edge case handling
+
+**Decomposition**
+- Core objective and constraints
+- Output format requirements
+- Explicit vs implicit expectations
+- Context dependencies and variable elements
+
+### 2. Apply Chain-of-Thought Enhancement
+
+**Standard CoT Pattern**
+```python
+# Before: Simple instruction
+prompt = "Analyze this customer feedback and determine sentiment"
+
+# After: CoT enhanced
+prompt = """Analyze this customer feedback step by step:
+
+1. Identify key phrases indicating emotion
+2. Categorize each phrase (positive/negative/neutral)
+3. Consider context and intensity
+4. Weigh overall balance
+5. Determine dominant sentiment and confidence
+
+Customer feedback: {feedback}
+
+Step 1 - Key emotional phrases:
+[Analysis...]"""
+```
+
+**Zero-Shot CoT**
+```python
+enhanced = original + "\n\nLet's approach this step-by-step, breaking down the problem into smaller components and reasoning through each carefully."
+```
+
+**Tree-of-Thoughts**
+```python
+tot_prompt = """
+Explore multiple solution paths:
+
+Problem: {problem}
+
+Approach A: [Path 1]
+Approach B: [Path 2]
+Approach C: [Path 3]
+
+Evaluate each (feasibility, completeness, efficiency: 1-10)
+Select best approach and implement.
+"""
+```
+
+### 3. Implement Few-Shot Learning
+
+**Strategic Example Selection**
+```python
+few_shot = """
+Example 1 (Simple case):
+Input: {simple_input}
+Output: {simple_output}
+
+Example 2 (Edge case):
+Input: {complex_input}
+Output: {complex_output}
+
+Example 3 (Error case - what NOT to do):
+Wrong: {wrong_approach}
+Correct: {correct_output}
+
+Now apply to: {actual_input}
+"""
+```
+
+### 4. Apply Constitutional AI Patterns
+
+**Self-Critique Loop**
+```python
+constitutional = """
+{initial_instruction}
+
+Review your response against these principles:
+
+1. ACCURACY: Verify claims, flag uncertainties

+3. QUALITY: Clarity, consistency, completeness
+
+Initial Response: [Generate]
+Self-Review: [Evaluate]
+Final Response: [Refined]

+```
+
+### 5. Model-Specific Optimization
+
+**GPT-5/GPT-4o**
+```python
+gpt4_optimized = """
