✍️ Advanced Prompt Engineering

Prompt engineering is both an art and a science. The way you communicate with LLMs dramatically affects the quality, accuracy, and usefulness of their outputs.

Essential Techniques

Chain-of-Thought (CoT)

Ask the model to “think step by step” before giving its final answer. This dramatically improves performance on reasoning tasks.

Few-Shot Prompting

Provide 2-5 examples of the desired input-output format. The model learns the pattern and applies it to new inputs.

System Prompts for Agents

Well-crafted system prompts define the agent’s personality, capabilities, constraints, and output format. They include role descriptions, available tools, and behavioral guidelines.

Structured Output

Use JSON schemas or output parsers to ensure consistent, machine-readable responses from LLMs.

🛡️ Prompt Security

Prompt Injection: Attackers try to override your system prompt
Jailbreaking: Attempts to bypass safety measures
Defense Strategies: Input validation, output filtering, sandboxed execution

💻 Code Example: Simple AI Agent


import openai

def create_agent(system_prompt, tools):
    """Create a simple AI agent with tool access"""
    messages = [{"role": "system", "content": system_prompt}]
    
    def run(user_input, max_iterations=10):
        messages.append({"role": "user", "content": user_input})
        
        for i in range(max_iterations):
            response = openai.chat.completions.create(
                model="gpt-4",
                messages=messages,
                tools=tools,
                tool_choice="auto"
            )
            
            message = response.choices[0].message
            messages.append(message)
            
            # Check if agent wants to use a tool
            if message.tool_calls:
                for tool_call in message.tool_calls:
                    result = execute_tool(tool_call)
                    messages.append({
                        "role": "tool",
                        "tool_call_id": tool_call.id,
                        "content": result
                    })
            else:
                # Agent is done - return response
                return message.content
        
        return "Max iterations reached"
    
    return run

# Usage
agent = create_agent(
    "You are a helpful research assistant.",
    tools=[web_search, calculator]
)
answer = agent("What are the latest AI trends?")

This example shows the fundamental agent pattern: an LLM that can iteratively call tools until the task is complete.

✅ Best Practices for Few Shot Prompting Examples

Architecture

  • Start Simple: Begin with a single agent before building multi-agent systems
  • Define Clear Boundaries: Each agent should have a well-defined scope and responsibility
  • Implement Fallbacks: Always have graceful error handling and human escalation paths
  • Use Structured Outputs: JSON schemas ensure consistent, parseable agent responses

Performance

  • Choose the Right Model: Not every task needs GPT-4; many work well with smaller, faster models
  • Cache Aggressively: Cache LLM responses, embeddings, and tool results
  • Limit Iterations: Set maximum loop counts to prevent runaway costs
  • Stream Responses: Use streaming for better user experience

Safety & Reliability

  • Implement Guardrails: Validate inputs and outputs at every step
  • Log Everything: Comprehensive logging is essential for debugging
  • Test Thoroughly: Unit test individual components, integration test workflows
  • Monitor in Production: Track latency, error rates, and cost metrics
