Code health
6.5out of 10Fair
This codebase scores 6.5 out of 10 on defect risk, which we rate fair. It also scores maintainability 7.6 and static performance risk 10.0 out of 10. The three are scored separately and never blended into one number. The files you change most are the weak spot: 158 of 2,735 files are git hotspots, and they average 3.3.
