Tips for Best Results

Techniques to elevate response fidelity

•Provide rich background context rather than one-sentence inputs to receive deep, non-generic responses.
•Engage in multi-turn conversation: use the initial output as a baseline, then ask the AI to sharpen specific sections.
•Prompt the model to highlight any hidden assumptions or missing trade-offs in its recommendations.

Common Mistakes to Avoid

Frequent failure modes and anti-patterns

•Giving minimal context and expecting nuanced, expert-level strategic output.
•Not validating factual references, citations, or statistical claims with verified primary sources.
•Skipping the customization step and pasting raw bracketed template variables into the AI chat.
