Why grade F?
score · 0 / 100The current grade reflects 3 critical findings (any 2+ CRITs → F).
3 CRIT2 HIGH2 MED0 LOW
To reach a higher grade
- DReach Dtarget score 30
Resolve 2 of your 3 CRIT findings — any single CRIT still keeps you at D.
- CReach Ctarget score 55
Resolve all 3 CRIT findings.
- BReach Btarget score 75
Resolve all 3 CRIT.
- AReach Atarget score 95
Resolve all 3 CRIT + all 2 HIGH.
Thresholds are documented at /docs/grading. Source-of-truth is the grade() function in @skillox/scanner.
