Code health
9.4out of 10Excellent
This codebase scores 9.4 out of 10 for code health, which we rate excellent. It also scores maintainability 8.9 and static performance 10.0 out of 10. The three are scored separately and never blended into one number.
Do next
1 thing worth doing this quarter.
Worth planning
Delete 36 unused symbols and files (540 lines)
Nothing in the graph reaches them, across 10 files; every reader and agent pays to skip them.
- symbols
- 36
- lines
- 540
- safe to delete
- Yes(inferred)
Medium effort
Improve what Repowise can see
Add a test coverage report
Without one, Repowise cannot tell tested code from untested code, so every test-related action says “unknown”.
- line coverage
- Unknown, no report
Small effort
- Lines of code
- 10.1K
