An idiomatic Go project layout keeps executable entry points minimal in cmd/, private code in internal/, and reusable libraries in pkg/. This structure prevents messy repositories by enforcing clear conventions for where code should live based on export needs.

Use go.work for multi-module development scenarios in a Go monorepo when you need to manage multiple modules simultaneously. It provides a maintainable growth path for multi-module repositories, whereas single-module projects should rely solely on go.mod.

The best way to organize multiple binaries in a Go repository is placing each executable entry point in its own subdirectory under cmd/ with minimal logic. This enforces correct Go module and package naming conventions while keeping business logic separated.

Choose internal/ for private code you want to restrict from external imports, and pkg/ for reusable libraries intended for external consumption. This decision enforces correct Go conventions and ensures your repository structure matches your code export needs.

Yes, a minimal Go project layout works for a simple CLI tool by right-sizing the structure to match your specific build target. You can start with a basic cmd/ directory and go.mod file, expanding to internal/ or pkg/ only as your codebase grows.
