研究方向
The issue requests a clang tidy readability check to replace integer constants like `~0` or ` 1` for unsigned types with `std::numeric limits<type>::max()`. The implementation should be located in the clang tools extra directory, following existing patterns such as the `readability *` checks. There is an assignee (@JonasToth) and 14 comments, indicating prior discussion. Review the comments to understand any design decisions or blockers, and examine existing clang tidy checks for style and structure before implementing new AST matchers.
