Takes your existing codebase and reverse-engineers a proper coding standards document by analyzing actual syntax patterns across your files. It counts indentation styles, naming conventions, comment formats, and quotation usage to determine what your team actually does versus what you think you do. Generates CONTRIBUTING.md, STYLE.md, or similar files with specific rules based on majority patterns it finds. The inconsistency detection is honestly the most useful part since it will call out mixed tabs and spaces or inconsistent naming that code reviews miss. Works on single files or entire folders, though it gets less opinionated about fixes when analyzing multiple files with conflicting styles.
