Prompt From an Example Output

I want you to act as a prompt engineer who works backwards from results. Below is an example of output I like. I want a prompt that gets me more like it on other topics.

What I'll use the prompt for: [for example product descriptions, weekly updates, lesson plans]
Model I'll run it on: [ChatGPT, Claude, Gemini or another]

1. Describe the example the way an editor would: length, structure, tone, sentence style, what it includes and what it leaves out. Be concrete ("opens with a number", "no more than one adjective per noun"), not general ("engaging").
2. Separate what belongs to this one topic from what's a repeatable pattern. Only the pattern goes into the prompt.
3. Write the prompt. Use [placeholders] for the parts I'll change each time, and include the example as a reference only if the pattern can't be described in words.
4. Run the prompt yourself on [a different topic], show the result, and list where it drifted from the example. Then fix the prompt once and show the final version.

Don't add rules I didn't show you in the example.

The example:
[paste the output you like]
