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: 76,830 characters.
- The repository as it stood, pressy, with its history and its dependencies installed.
- Its own tools, and the main model providers’ APIs, but nothing else online.
How it is checked
Existing defect. The problem is already in the repository, and the agent must notice it.
The defect check: file found. The named file was found in the starting files; this alone does not prove the defect.
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
