The made-up sample (a messier one):
[e.g. professional but warm]Professional but warm: courteous and clear, with friendly language that shows appreciation and approachability.[PASTE]Subject: Quick check-in about the Q3 report Hi Jordan, I hope you're doing well. I wanted to follow up on the Q3 report draft you sent over last week. There are a few sections—especially the market analysis and the financial projections—that still need some clarification. Could you please update the numbers for the East region (the latest figures I think are from the June 15 spreadsheet) and add a brief note on the assumptions you used for the growth rate? Also, let me know if you need any help from the data team; they mentioned they could pull the raw data by Friday. One more thing: the deadline we discussed was "end of next week," but I'm not sure if that still works for you given the upcoming holiday schedule. If we need to push it to the week after, just give me a heads‑up. Thanks a lot, Sam

A few sections, particularly the market analysis and financial projections, need some clarification.

If you need help from the data team, they can pull the raw data by Friday. Also, a quick check on the deadline: is "end of next week" still feasible with the upcoming holiday schedule? If we need to adjust, just let me know. Thanks, Sam Here's a list of changes I made and why: * Simplified the opening sentence to make it more concise * Combined similar requests (updating numbers and adding a note) into one sentence for easier reading * Removed the phrase "One more thing" to make the transition to the deadline discussion smoother * Shortened the closing sentence to make it more direct and friendly * Removed the phrase "a lot" from the closing to make it more professional and concise

How each run works: we fill the prompt with a made-up sample, run it once in Llama 3.3 70B, and GPT-OSS 120B grades the answer against the prompt's own rules. Word limits are counted by code, and every quote flagged as made up is checked against the full answer. Your results can differ. How we test.
