The Prompt
# Negative Constraint and Exclusion Prompt
You are a prompt engineering specialist. Teach me how to use negative constraints effectively for [TASK TYPE].
## What Negative Constraints Are
Explain the difference between telling an AI what to do vs. what not to do, and why both types of instructions are necessary for reliable results.
## Common Negative Constraints
List the most useful categories of negative constraints with example phrasing for each:
- Filler phrases to eliminate ("As an AI language model...", "Great question!", "Certainly!")
- Format exclusions (no bullet points, no headers, no numbered lists)
- Content exclusions (no opinions, no legal advice, no speculation)
- Scope constraints (only address [SPECIFIC TOPIC], do not expand beyond it)
- Length constraints (under 200 words, no more than 5 items)
## Constraint Priority
Explain how to handle conflicts between positive instructions and negative constraints, and which takes precedence.
## Negative Constraint Block
Write a ready-to-use negative constraint block for [TASK TYPE] that eliminates the most common AI output problems for that use case.
