Project Structure

This one audits your project structure and tells you where code should live. It checks for colocation issues, directory anti-patterns, and whether you're doing feature-based or layer-based grouping properly. The workflow is straightforward: it detects your project type (React, Next.js, Express, monorepo, whatever), audits against its ruleset, then recommends where new code belongs. Useful when you're mid-refactor and your utils folder is a junk drawer, or when you need to justify why that new feature shouldn't go in a random misc directory. It respects existing patterns instead of forcing a rewrite, which is the right call for real codebases.
