YAML Whisperer
The same shape again, in YAML this time: three top-level keys, one of them a list.
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.
- Valid YAML with keys title, author, tags
- tags is a list of 3
- No markdown fence
- You didn't write it yourself
WHAT THIS TRIAL TEACHES
Say “top level” out loud. Otherwise it tucks your keys under a helpful parent and technically answers you.
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 2 IS ABOUT MACHINE-READABLE
The step from “looks right” to “parses”. Every rule here runs a real parser, so output a downstream system would reject fails here too — a stray code fence is a failure, not a formatting quibble.
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.
