Prompt Engineering for Large Language Models

Structured prompting, few-shot examples, tool use, and output control.

Slide 92

Overview

Prompt engineering enables systematic interaction with LLMs through deliberate design patterns and structured communication methods.

Key Concepts

Structured Prompting

Use clear sections like task, constraints, format, and examples to guide model behavior.

Few-Shot Examples

Demonstrate correct output patterns by including sample inputs and responses.

Tool Use

Integrate tools or APIs the model can call for retrieval, calculations, or external actions.

Output Control

Specify format requirements and constraints to produce predictable outputs.

Prompt Engineering Process

1

Define Task

Identify purpose and expected output shape.

2

Structure Prompt

Organize instructions, constraints, and examples.

3

Integrate Tools

Connect APIs or processing steps the model can use.

4

Refine Outputs

Iterate by adjusting phrasing, structure, or examples.

Use Cases

Enterprise Automation

Workflow automation requiring structured and reliable outputs.

Data Transformation

Converting unstructured data into formats like JSON or tables.

RAG & Tools

Enabling model-driven information retrieval or API-based actions.

Comparison

Naive Prompting

  • Minimal structure
  • Unpredictable output
  • No examples
  • Lack of constraints

Engineered Prompting

  • Clear structure and format control
  • Predictable, consistent responses
  • Uses few-shot demonstrations
  • Integrates tools and workflows

FAQ

Why use structured prompts?

They reduce ambiguity and improve model reliability.

How many few-shot examples are needed?

Often 2–4 examples are enough for pattern learning.

When should I use tool-based prompting?

Use tools when you need real-time data, calculations, or precise retrieval.
