As prompts grow, they become harder for both you and the AI to read. A little structure makes complex requests far more reliable.
Separate instructions from content
Put the text you want processed between clear markers, so the model doesn't confuse it with your instructions:
Summarise the article between the triple quotes in 5 bullet points.
"""
[paste article]
"""
Some people use XML-style tags like <article>...</article>, which work well with many models.
Use labelled sections
ROLE: You are an experienced HR manager.
TASK: Write a job description for a junior designer.
CONTEXT: 20-person startup, remote-first, values curiosity.
FORMAT: Headings, bullet points, under 400 words.
AVOID: Jargon like "rockstar" or "ninja".
Number your requirements
Numbered lists make it easy to check whether every requirement was met, and easy to refer back to: "Requirement 3 is missing."
Specify the output format
Tables, JSON, bullet points or a specific template: say exactly what you want, ideally with an example.
Keep it readable
If you can't quickly understand your own prompt, the AI may struggle too. Structure is clarity.
