Define a segment with explicit inclusion rules
Make a segment precise enough to find in your data and act on differently.
What this prompt helps you do
A segment definition with inclusion rules, size, distinguishing behaviours, and the decisions it should change.
When to use it
A segment is being discussed without a definition anyone could apply to the data.
What to prepare
The goal, relevant source material, constraints, examples, and the decision or action this should support.
How to get a strong result
Give rules an analyst could run; a segment nobody can query is a conversational shorthand, not a segment.
How to use this prompt
Replace each placeholder with accurate context. Paste the complete prompt into Claude, review the response critically, resolve important questions, and use it as a considered input to the next decision—not as an unchecked final answer.
