Worked on the github/codeql repository to enhance static analysis for C and C++ by improving the handling of basic integral types. Focused on extending the BasicIntTypes query to recognize standard C types such as uint8_t and bool, the work broadened typedef coverage and refined type classification to reduce false positives. The approach included updating and strengthening test cases to validate new typedef scenarios and prevent regressions. Using skills in code analysis, static analysis, and testing, the developer addressed reviewer feedback and finalized robust integration of these changes, ensuring more accurate code quality checks for projects utilizing typedefs in C and C++.
