End-To-End SWE Task Benchmark (Windsurf)
Dropped
Agents start a fresh Cascade conversation from a user intent and must pass a selected set of unit tests. A 0 to 10 score blends test pass rate and a judge score.
Windsurf reported it once, as a chart without printed values, in the SWE-1 launch post. Scoring mixes unit tests with a model judge.
