How to Use These Prompts Effectively

1. Replace All Placeholders

Every prompt has placeholders marked with [BRACKETS]. Replace these with your actual content:

❌ Don't leave placeholders:

Analyze [YOUR DATA]

✅ Replace with actual content:

Analyze Q1 sales: $120K revenue, 450 customers, 23% growth

2. Add Context When Needed

The more context you provide, the better Claude's response. Include:

  • Who your audience is
  • What format you need
  • What tone/style to use
  • Any constraints (word count, style guide, etc.)

3. Iterate and Refine

First response not perfect? Add a follow-up:

  • "Make this more concise"
  • "Add more technical detail"
  • "Rewrite in a friendlier tone"
  • "Focus more on X and less on Y"

Prompt Best Practices

✅ Do This

• Be specific about what you want

• Include examples when possible

• Define the output format

• Use XML structure for complex requests

• Add thinking tags for reasoning tasks

❌ Avoid This

• Vague requests ("make it better")

• Assuming Claude knows your context

• Skipping examples

• No output format specified

• Generic quality terms without definition
