This guide builds on the Basic Prompting Guide and explores advanced techniques to refine your interactions with LLM chatbots.

Understanding the Chatbot’s Capabilities

LLMs are trained on vast amounts of data but lack true reasoning ability. Using strategic prompting can help guide the model’s responses to be more relevant and insightful for Extension professionals.

Advanced Prompting Techniques

  1. Chain of Thought Prompting
  • Guide the chatbot through logical reasoning by breaking prompts into steps.
  • Example:
    • ✅ “Step 1: Explain what integrated pest management is. Step 2: Describe how it is used in North Carolina farms. Step 3: Provide an example of a successful IPM case study in NC.”
    • ❌ “Tell me about pest management.”
  1. Role-Based Prompting
  • Assign a specific role to the chatbot for more tailored responses.
  • Example:
    • ✅ “Act as an NC State agricultural specialist and assess the impact of climate change on soybean yields in North Carolina.”
    • ❌ “Explain the effects of climate change on crops.”
  1. Format-Specific Prompting
  • Ask for responses in a preferred structure, such as tables, bullet points, or numbered lists.
  • Example:
    • ✅ “List the pros and cons of using biochar for soil health in North Carolina in a table.”
    • ❌ “Tell me about biochar.”
  1. Using Constraints and Guidelines
  • Set limits on length, style, or complexity to fit your needs.
  • Example:
    • ✅ “Explain precision agriculture in two sentences using simple language for a rural community meeting.”
    • ❌ “Explain precision agriculture.”
  1. Iterative Refinement & Follow-ups
  • Engage in a back-and-forth approach to refine responses.
  • Example:
    • User: “Summarize the North Carolina Farm Act in 100 words.”
    • Chatbot: (Provides a response)
    • User: “Can you make it more concise?”
  1. ReAct Prompting (Reasoning + Acting)
  • Encourage the chatbot to reason through a problem and suggest an action.
  • Example:
    • ✅ “Analyze the challenges of soil degradation in North Carolina and suggest three sustainable farming practices.”
    • ❌ “Tell me about soil degradation.”
  • This approach is particularly useful for research-based inquiries where critical thinking is needed.
  1. Meta Prompting
  • Guide the chatbot to help generate its own prompt.
  • Example:
    • ✅ “Create a prompt detailing a proposal regarding soil conservation grants.”
    • ❌ “Make a soil conservation grant proposal.”
  • Meta prompting helps provide key information, examples, and context to build prompt components

Example Comparisons

Basic Prompt Advanced Prompt
“Tell me about sustainable agriculture.” “Explain sustainable agriculture practices in North Carolina with a focus on small farms.”
“What are the benefits of cover crops?” “List 5 benefits of cover crops specific to North Carolina’s climate and soil conditions.”
“Describe the rural economy.” “Describe the rural economy of North Carolina in a table with key sectors, employment trends, and economic challenges.”

Mastering advanced prompting techniques can significantly improve the quality of chatbot responses. By using structured, role-based, and iterative prompts, you can obtain highly relevant and tailored information for your work.
