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.
