Type Safety Review
Detection
| ID | Pattern | Fix |
| --- | ----------------------------- | ----------------------------- |
| TS1 | any | unknown + type guard |
| TS1 | Implicit any | Explicit type annotation |
| TS2 | value as Type | Type guard function |
| TS2 | value! (non-null assertion) | Explicit null check |
| TS3 | function fn(data) (untyped) | function fn(data: Type) |
| TS3 | Missing return type | Explicit : ReturnType |
| TS4 | default: without exhaustive | default: assertNever(value) |
| TS5 | strictNullChecks: false | Enable in tsconfig |
| TS5 | noImplicitAny: false | Enable in tsconfig |
Criteria
Type coverage >= 95%. Any usage = 0. Strict mode all enabled.
