* [enumlinter](https://github.com/THE108/enumlinter) - Enum linter for enumerated types in Go.
* [errcheck](https://github.com/kisielk/errcheck) - Errcheck is a program for checking for unchecked errors in Go programs.
* [gas](https://github.com/GoASTScanner/gas) - Inspects source code for security problems by scanning the Go AST.
* [go vet](https://golang.org/cmd/vet/) - Vet examines Go source code and reports suspicious constructs, such as Printf calls whose arguments do not align with the format string. Can check shadowing of variables, but must be enabled explicitly.
* [staticcheck](https://github.com/dominikh/go-tools/tree/master/cmd/staticcheck) - staticcheck is `go vet` on steroids, applying a ton of static analysis checks you might be used to from tools like ReSharper for C#.
