Bad examples on purpose.

The agent will happily write the version you hate if you never show it. “Don’t be salesy” is vague. A bad example is a fence.

Paste one bad line. Say what is wrong in a few words. Ask for a version that avoids that fault.

Write a one-line note confirming a 3pm call.
Do not do this: “So excited to lock in this amazing chat!!!”
What is wrong: hype, extra marks, the word amazing.
Write the note.

Use a line you have actually deleted. Name the fault. Keep the ask small.

A bad example you can keep next to the good one. Closing a door is part of the brief.
