How does this skill help reduce AI hallucinations?

It implements best practices such as providing reference context, setting explicit constraints, and using delimiters to ground the model and ensure more accurate responses.

Can I use this skill to get JSON responses from an AI?

Yes, the skill includes specific templates and retry logic patterns designed to force LLMs to return valid, structured JSON data for programmatic use.

What is the Prompt Engineering skill for Claude Code?

It is a specialized capability that provides developers with advanced techniques, templates, and patterns like Chain of Thought to maximize the effectiveness of Large Language Model interactions.

What is the ReAct pattern included in this skill?

The ReAct pattern combines reasoning (Thought) with action (Action/Observation), allowing the AI to solve complex problems by thinking through steps and interacting with external data.
