Prompt Engineering for Large Language Models

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

Overview

Prompt engineering is the practice of designing inputs that guide large language models to produce accurate, reliable, and controllable outputs.

Key Concepts

Structured Prompting

Use templates, roles, constraints, and task steps to make requests clearer and more actionable.

Few‑Shot Examples

Provide sample inputs and outputs to demonstrate the pattern the model should follow.

Tool Use

Enable models to call APIs, check facts, or perform calculations through dedicated tool descriptions.

Output Control

Specify format, style, and constraints to ensure outputs are predictable and structured.

Prompt Engineering Process

1

Define the Goal

Clarify the task and success criteria.

2

Design Structure

Add roles, instructions, and constraints.

3

Add Examples

Provide few‑shot references if needed.

4

Iterate

Test, refine, and measure improvements.

Use Cases

Content Generation

Blog posts, emails, product descriptions, and more.

Data Transformation

Classification, extraction, summarization.

Technical Reasoning

Code generation, debugging, analysis.

Traditional Prompting vs Structured Prompting

Traditional

  • Short and unclear instructions
  • Inconsistent outputs
  • No formatting control

Structured

  • Clear roles and steps
  • Few‑shot examples guide behavior
  • Predictable and structured results

FAQ

Do all prompts need few‑shot examples?

No. Many tasks succeed with zero‑shot prompts if well structured.

Does adding structure reduce creativity?

No. It improves reliability while still allowing creative output.

When should tools be used?

When precision, external data, or computation is required.
