FAQPage Schema
How do I write effective system prompts for LLM agents?

To write effective system prompts for LLM agents, use a structured workflow that synthesizes official documentation and research to craft model-appropriate, robust instructions. This ensures consistent agent behavior across different model families.

What is the best way to improve prompt engineering for multiple AI models?

The best way to improve prompt engineering for multiple AI models is applying a diagnostic framework with a 6-dimension defect taxonomy. This identifies targeted fixes to refine prompts for consistent performance across Claude, GPT, Gemini, and Llama.

How do I review and diagnose defects in existing AI prompts?

You can review and diagnose defects in existing AI prompts by running them through a diagnostic framework based on a 6-dimension defect taxonomy. This process identifies specific weaknesses and applies targeted fixes to produce an improved version.

Can I use a single prompt engineering workflow for Claude, GPT, and Gemini?

Yes, you can use a single prompt engineering workflow for Claude, GPT, and Gemini by applying a universal CTCO and structured output approach. This provides model-specific guidance while maintaining consistent prompt quality across families.

How do I write tool descriptions for AI agents and chatbots?

You can write tool descriptions for AI agents and chatbots using a dedicated tool description mode. It synthesizes production patterns and research to generate robust, ready-to-use tool and task prompts for system-level instructions.
