Go Project Layout
Structure follows size. The biggest layout mistake in Go is copying a microservice skeleton for a 500-line tool — or growing a 50-package service inside a flat directory. Match the layout to the project.
Community default. A project skill or agent-config rule that explicitly supersedes
go-project-layouttakes precedence over this one.
1. Pick the Layout by Project Size
| Project | Layout |
|---|---|
| Small tool, single binary, <5 files | Flat: everything in package main at the root |
| Library for others to import | Root package named after the module, internal/ for helpers |
| Service with one binary | cmd/<name>/main.go + internal/ packages |
| Multiple binaries sharing code | cmd/<name1>/, cmd/<name2>/ + internal/ |
