t10: Vague request -- GPT-6.1 Sol vs Claude Opus 5.5
The whole request: "Add exports to this tool." Every job also had the same few lines about the work folder, a time box and saying DONE at the end.
Opus: 57.9 s. Sol: 262.1 s. Sol took 4.5 times as long.
Opus (s)Sol (s)
Hidden tests: Opus 2 of 7, Sol 2 of 7.
Blind judge pick: Opus (clear).
Neither passed every hidden test: the tests wanted an option called --export.
"Solution B [Opus] uses Node's built-in `util.parseArgs` for argument parsing, which is much more robust and idiomatic than Solution A [Sol]'s manual parsing loop. Both solutions implement the requested formats and file output well, but B [Opus]'s code is cleaner and more maintainable."
"Excellent implementation of JSON and CSV exports with robust CLI options and thorough testing."
"Excellent implementation of JSON and CSV exports with robust CLI argument parsing and comprehensive tests."
