Enforces strict TypeScript practices — proper generics, discriminated unions, exhaustive checks, and elimination of any. Weak types propagate silently through a codebase, so this skill catches the patterns that erode type safety before they spread.
BeforeMerge scans your pull requests against all 5 TypeScript rules automatically. Get actionable feedback before code ships.
Never use `any` as a type annotation. `any` disables all type checking for that value and everything it touches, spreading through your codebase like a virus — one `any` can silently disable type safety across dozens of files.
A review skill that ensures your TypeScript code delivers on its promise of type safety rather than just adding syntax overhead.
Run this on any TypeScript project, particularly after adding new modules or when reviewers frequently catch type-related issues. Essential for shared libraries where consumers depend on accurate types.
