Who it's for

Founders who want to post short, single-tweet ideas daily without sounding generic

What they report

Lewis Kallow says a few-shot prompt built from viral tweets wrote a tweet for Every CEO Dan Shipper that got 200,000 impressions. He says his library of few-shot prompts lets him create and repurpose content about six times faster, saving around eight hours a week.

Example

Kallow's first version kept adding emojis and hashtags. Adding more instructions in caps did not fix it. Deleting the words 'tweet' and 'social media' from the style guide did. Adding one bad output with a short note on why it fails took a separate rule from about 90% compliance to 100%.

How to do it

  1. Pick only posts that already hit your success metric. Kallow used single tweets with 100,000+ impressions (ideally 1M+).
  2. Keep the example set narrow if you want one format. Widen it if you want variety (for ad tests, for example).
  3. Paste 5 to 10 examples and have the model write a style guide from them.
  4. Run the guide on an article, transcript or note you want to turn into posts.
  5. If a bad habit keeps showing up, delete words that trigger it instead of adding louder rules.
  6. Paste one bad output into the prompt with a one-line reason it fails, next to one good output.

The prompt

Fill in the [brackets]
Copy prompt

Below are [8] single posts that each passed [100,000] impressions. They are examples to learn from, not topics to copy. Step 1: Write a short style guide from them. Cover how they open, sentence length, structure, what they leave out, and how they end. Step 2: Read the SOURCE at the bottom. Write 5 single posts that follow your style guide and use only ideas from the SOURCE. Rules: - One idea per post. - Under 280 characters. - No emojis. No hashtags. - Do not invent numbers, names or results that are not in the SOURCE. This is a bad output and why it fails: [paste a bad post] -> Fails because [reason]. This is a good output and why it works: [paste a good post] -> Works because [reason]. EXAMPLES: [paste examples] SOURCE: [paste article, transcript or notes]
