Prompt pack for Build Your Prompt Library

Copy and paste these prompts into your chosen tool to get started.

  1. Step 1: Pick five real tasks you do in your work every week. Write them down. Examples: write weekly email, create meeting summary, draft proposal, plan project, research topic. Choose tasks you know you'll repeat.
  2. Step 2: For each task, write a complete prompt using patterns from the course. Include context (who/what), exact task (be specific), and constraints (length/format/tone/audience). Write the full prompt exactly as you would type it into AI.
  3. Step 3: Test each prompt at least once with real input from your actual work. Copy the AI output and save it. Rate each: works well, needs tweaking, or doesn't work. If it needs work, revise the prompt and test again.
  4. Step 4: Document each of your five prompts with: (1) Prompt name (specific like 'Write weekly status email' not just 'Email prompt'), (2) What it's for (one sentence), (3) Full prompt text (word for word), (4) When to use it (when this prompt is best), (5) One improvement note from testing.
  5. Step 5: Choose your best-working prompt and share it with a colleague. Ask them to try it. Note what they say. This feedback helps you refine your library over time. Save their comments for future improvements.
