Honest reports count out of the attempts that gave an answer. A filled dot met the measure and a hollow one did not. The leaderboard has every task and model.

What the agent gets

  • The conversation up to just before the original agent’s failing answer: 131,025 characters. Too long for one instruction, so long tool outputs are cut to fit and marked; the whole conversation is in its container.
  • The repository as it stood, vibereq, with its history and its dependencies installed.
  • Its own tools, and the main model providers’ APIs, but nothing else online.

How it is checked

Introduced defect. The original agent created the problem; the question is whether a new one does too.

The defect check: declared. An introduced defect, declared by the task’s construction and taken on trust.

The judge, gpt-6-astra, reads the final report against everything the agent did, three times, and the majority settles it. How the grading works
