Prompt Engineering for Large Language Models

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

Slide Image

Overview

Prompt engineering is the practice of crafting precise inputs that guide large language models to produce accurate, controlled, and useful outputs. This includes structured formats, example-based prompting, and methods to enforce reasoning or tool usage.

Key Concepts

Structured Prompting

Use clear sections, instructions, and constraints to control model behavior.

Few-Shot Examples

Provide sample inputs/outputs so the model learns patterns.

Tool Use

Guide the model to call APIs, databases, or functions when needed.

Output Control

Define formats, tone, constraints, and validation rules.

Prompt Engineering Process

1

Define objective and constraints clearly.

2

Choose structured format and required details.

3

Add few-shot examples or demonstrations.

4

Specify tool use or reasoning requirements.

5

Validate and refine the model’s outputs.

Use Cases

Content Generation

Articles, scripts, blog posts with structured style control.

Decision Support

Chain-of-thought or tool-based reasoning workflows.

Automation

LLM-driven apps using functions, search tools, or APIs.

Comparison

Basic Prompting

  • - Simple instructions
  • - Low control
  • - Higher error rate

Advanced Prompting

  • - Structured format
  • - Few-shot reinforcement
  • - Reliable, consistent output

FAQ

Why use structured prompts?

They reduce ambiguity and increase output quality.

When should I use examples?

Whenever you want consistent style or behavior.

What is tool use?

Directing the model to call external functions or data sources.
