Being clear and direct

Key Concept

• The first line of your prompt is the most important — use it to set the task clearly
• Use simple, direct language with an action verb to tell Claude exactly what to do

Best Practices for First Line

• Start with an action verb (write, generate, identify, create, etc. )
• Specify what Claude needs to produce
• Include relevant details about expected output format or content

Examples

• "Write three paragraphs about how solar panels work"
• "Identify three components of your prompt"
• "List countries that use geothermal energy and for each include generation stats"
• "Generate a one day meal plan for an athlete that meets their dietary restrictions"

Practical Impact

• Applying this technique improved the example score from 2. 32 to 3. 32
• Clear, direct prompts lead to better outputs from Claude
• This is the foundation for further prompt optimization

Takeaways

• The first line of your prompt is most important — use it to set the task clearly with an action verb
• Use simple, direct language to tell Claude exactly what to do and what output format you need
• Clear, direct prompts significantly improve Claude's output quality (demonstrated by score improvement from 2. 32 to 3. 32)
