Prompt Engineering

Design and optimize prompts for large language models (LLMs) to achieve reliable, high-quality outputs across diverse tasks.

Purpose

This skill provides systematic techniques for crafting prompts that consistently elicit desired behaviors from LLMs. Rather than trial-and-error prompt iteration, apply proven patterns (zero-shot, few-shot, chain-of-thought, structured outputs) to improve accuracy, reduce costs, and build production-ready LLM applications. Covers multi-model deployment (OpenAI GPT, Anthropic Claude, Google Gemini, open-source models) with Python and TypeScript examples.

When to Use This Skill

Trigger this skill when:

• Building LLM-powered applications requiring consistent outputs
• Model outputs are unreliable, inconsistent, or hallucinating
• Need structured data (JSON) from natural language inputs
• Implementing multi-step reasoning tasks (math, logic, analysis)
• Creating AI agents that use tools and external APIs
• Optimizing prompt costs or latency in production systems
• Migrating prompts across different model providers
• Establishing prompt versioning and testing workflows
