SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill streamlines the complex process of designing, optimizing, and evaluating prompts for Large Language Models (LLMs), ensuring maximum performance and efficiency.

Core Features & Use Cases

  • Prompt Design & Refinement: Create new prompts or improve existing ones for better accuracy, token efficiency, and reliability.
  • Structured Output Generation: Build prompts that reliably output data in formats like JSON or function calls.
  • Evaluation Frameworks: Develop and implement systematic ways to test and measure prompt performance against defined metrics.
  • Use Case: You're building a new AI feature that needs to summarize customer feedback. Use this Skill to design a prompt that not only summarizes accurately but also extracts key sentiment and topics, and then test it against a diverse set of feedback examples to ensure it performs well under various conditions.

Quick Start

Use the prompt-engineer skill to write a prompt that classifies customer reviews into positive, negative, or neutral sentiment, returning only the classification label.

Frequently Asked Questions about prompt-engineer

FAQPage Schema
How do I optimize LLM prompts for better accuracy and token efficiency?

To optimize LLM prompts for accuracy and token efficiency, engineer and refactor them using patterns like few-shot, Chain-of-Thought, and ReAct. This refines prompt design to improve reliability and reduce token consumption.

What is the best way to structure LLM outputs in JSON format?

The best way to structure LLM outputs in JSON format is by applying structured output generation techniques like JSON mode and function calling. This ensures the language model reliably returns data in the required structured format.

How do I create an evaluation framework to test prompt performance?

You create an evaluation framework to test prompt performance by implementing systematic testing methods like automated testing, LLM-as-judge, and human review. This measures prompt reliability against defined metrics under diverse conditions.

When should I use Chain-of-Thought prompting over zero-shot?

You should use Chain-of-Thought prompting over zero-shot when tasks require complex reasoning and step-by-step logic. Zero-shot relies on direct instructions, whereas Chain-of-Thought breaks down problems to improve accuracy on difficult reasoning tasks.

Can I use function calling to extract specific data from customer feedback?

Yes, you can use function calling to extract specific data from customer feedback. By designing prompts with structured output generation, you can reliably extract key sentiment and topics alongside summaries in a structured format.
