How to Get the Most from Prompt Libraries

1. Treat prompts as templates, not final answers. Add your context, audience, tone, constraints, and desired output format.
2. Specify the output. Ask for a table, bullet list, JSON, email draft, or step-by-step plan.
3. Include examples when accuracy matters. Few-shot examples often improve consistency.
4. Iterate. Save the prompts that work and refine them into your own personal library.
5. Check for sensitive data. Avoid pasting confidential or personal information into third-party prompt platforms.
