Overview

Prompt engineering is the practice of designing prompts that guide large language models toward accurate, controllable, and useful outputs. Techniques include structured instruction, examples, tool integration, and constraint-based output shaping.

Key Concepts

Structured Prompting

Use clear sections like task, input, and constraints.

Few-Shot Examples

Demonstrate the desired format or reasoning with examples.

Tool Use

Guide the model to call APIs, run functions, or delegate tasks.

Output Control

Specify formatting rules and constraints to maintain consistency.

Prompt Engineering Process

1. Define Task

Clarify goals.

2. Add Structure

Use sections.

3. Provide Examples

Show patterns.

4. Use Tools

Implement functions.

5. Test & Refine

Iterate outputs.

Use Cases

Content Generation

Articles, scripts, stories, technical guides.

Reasoning & Analysis

Step-by-step reasoning and problem solving.

Automation

Tool execution, workflows, agent behaviors.

Comparison

FAQ

Why is prompt structure important?

It helps the model understand expectations and reduces ambiguity.

How many examples should I provide?

Usually 1–3 examples are enough unless the format is complex.

When should I use tools?

When tasks require external data, calculations, or specialized logic.
