SmellBench Refactoring (OpenHands) - Cross-File Coordination: leaderboard
Metric: Cross-file coordination score (0-100): consistent handling of every affected file, import and helper; an LLM judge (model not named) scores the refactoring against the smell analysis on a 0-10 rubric, normalized to 0-100; 294 injected-smell refactoring cases (7 smell types, 3 difficulty levels, guided and targeted instructions) in 7 real Python repositories, run once in the Harbor Docker framework with a 20-minute budget, OpenHands agent harness; higher is better.
