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
• 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
• Vague requests ("make it better")
• Assuming Claude knows your context
• Skipping examples
• No output format specified
• Generic quality terms without definition
