About
This skill provides specialized guidance on how to correctly structure Cairo projects by splitting modules into multiple files and directories. It clarifies the critical relationship between `mod` declarations and the file system, helping users avoid common pitfalls like confusing `use` with module loading. By providing clear patterns for placing module bodies in `name.cairo` or `name/mod.cairo`, it ensures that developers can scale their Cairo applications with a clean, maintainable, and standards-compliant file hierarchy.
