How does it improve prompt reliability?

By moving away from vague instructions and implementing structured sections like Roles, Constraints, and negative examples, it reduces the 'sharp edges' of unpredictable AI behavior.

When should I use this skill?

Use this skill when you are building AI-powered applications, designing system prompts, or when you need a model to follow strict logic and output requirements.

What does the Prompt Engineer skill do?

It provides structured frameworks and best practices to help developers design more effective instructions for LLMs, ensuring higher accuracy and better adherence to formatting.

Does it support Chain-of-Thought reasoning?

Yes, it includes specific patterns for requesting step-by-step reasoning to improve the logic, debugging, and reliability of complex model responses.
