Jules benchmark

An asynchronous agent: you hand it a task against a repository and come back to a proposed change. Judged on wall clock that is expensive, and it posts one of the slower medians in the index, but the comparison is not quite like for like since nobody sits and watches it. Change quality was good and the tests it added were real tests rather than assertions that always pass.

What agent performance looked like in practice

Across 45 recorded executions this product met the published pass criterion cleanly 34 times, partially 7 times and failed 4 times. The rows above carry the reviewer note for every non clean outcome, which is the only way to tell a product that fails loudly from one that fails quietly.
