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: 122,512 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, gemini-voyager, 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
