The Reformat
Pipe-delimited in, comma-separated out — with the columns reordered to city, country, population and a header row on top.
THE SPEC
Every rule below is checked in code against whatever the model returns. All of them have to hold at once — there are no partial marks, and no opinion involved in the result.
- Exactly the reordered CSV
- No markdown fence
- No preamble, no sign-off
- You didn't write it yourself
WHAT THIS TRIAL TEACHES
Name the output columns in the order you want them. “Reorder the columns” without an order is a guess, and it will guess.
Knowing the move is not the same as landing it. You still have to write an instruction that makes the model comply, in 120 words or fewer, without writing the answer yourself.
WHY SET 4 IS ABOUT GIVEN INPUT, ONE RIGHT ANSWER
The most useful set here, and the only skill that doesn’t depreciate. Each trial hands you real data, and exactly one output is correct — so the question stops being “did it sound right” and becomes “did it process my data correctly”.
PLAY IT
You write the instruction, never the answer. The parser scores what comes back, and par for this one is 4 strokes. This set is part of Harfi Plus.
