Structure with XML tags

• Purpose: XML tags clarify and organize content within prompts, especially when interpolating large amounts of data
• Helps Claude understand what different sections of text represent
• Makes grouping and relationships between content explicit

• When to use:
• When inserting substantial content (e. g. , 20 pages of sales records)
• When mixing different types of content that could be ambiguous
• Even with shorter content, tags improve clarity about external inputs

• How to create tags:
• Use custom, descriptive tag names (e. g. , <sales_records>, <my_code>, <athlete_information>)
• More specific names are better than generic ones
• Wrap relevant content between opening and closing tags

• Benefits:
• Reduces confusion about which text serves which purpose
• Improves Claude's ability to parse and process information correctly
• Can lead to measurable improvements in output quality
• Makes prompts more maintainable and readable

• Example application: Wrapping athlete details in <athlete_information> tags makes it clear this is external input to consider when generating a meal plan

Takeaways

• XML tags organize and clarify different types of content in prompts, helping Claude understand what each section represents
• Use custom, descriptive tag names (like <sales_records> or <athlete_information>) rather than generic ones to improve clarity
• XML tags are especially valuable when inserting substantial content or mixing different content types that could be ambiguous
• Proper tagging reduces confusion, improves information processing, and can measurably enhance output quality
