Target reader: [WHO AND THEIR KNOWLEDGE LEVEL]
Goal: [WHAT SHOULD THE READER DO OR BELIEVE AFTER READING]
Length: [APPROXIMATE WORD COUNT]
Key constraint: [WHAT TO AVOID OR INCLUDE]

Then: produce the final outline with section titles and one-line descriptions.

Rewrite for a Different Audience
Rewrite any content for a completely different audience at low cost
Rewrite the following content for a completely different audience. The core information stays the same — everything else should change.

New audience: [WHO THE REWRITE IS FOR]

What stays: the core facts, key message, and structure

Compare and Contrast Two Arguments
Steelman two opposing arguments and find the crux of the disagreement
[V4 PRO THINKING ON — this is a reasoning task]

I need a rigorous comparison of two opposing arguments on the following topic. Do not take a side — steelman both.

Topic: [THE QUESTION OR DEBATE]
Argument A: [SUMMARISE ONE POSITION]
Argument B: [SUMMARISE THE OPPOSING POSITION]

For each argument:
1. The strongest version of the case (steelman)
2. The best evidence supporting it
3. The weakest point that critics target
4. What would have to be true for this argument to be correct

Then: identify the crux — the single factual or value disagreement that most explains why people reach different conclusions.
