Being Specific
How to replace vague language with precise instructions that leave no room for misinterpretation.
If there is one skill that separates great prompt engineers from everyone else, it's specificity. Every word you leave vague is a decision you're delegating to the AI. Sometimes that's intentional. More often, it's a missed opportunity to get exactly what you want.
Specificity isn't about making prompts longer — it's about making them more precise. A 20-word specific prompt outperforms a 200-word vague one every time.
Train yourself to spot vague words in your prompts. Here are the most common offenders and how to replace them:
Prompt
Common vague words and their specific replacements:
Vague
"Good" → "Scores above 8/10 on [criteria]" or "matches the quality of [specific example]"
Vague
"Short" → "Under 100 words" or "3 sentences maximum" or "fits in a tweet (280 characters)"
Vague
"Professional" → "Suitable for a board presentation" or "written for a C-suite audience" or "uses formal business English"
Vague
"Improve" → "Increase clarity by simplifying sentence structure" or "strengthen the argument with specific data"
Vague
"Some" → "Exactly 5" or "between 3 and 7" or "at least 10"
Numbers eliminate ambiguity. Whenever possible, replace qualitative descriptions with quantitative specifications.
