go-project-conventions

# Skill: Go project conventions ## Goal Provide a standard Go workflow with module caching, linting, security checks, and tests driven by Make. ## Make targets (recommended) - `make deps` → `go mod download` + `go mod tidy` - `make vet` → `go vet ./...` - `make lint` → `fmt` + `vet` + `staticcheck` (if available) - `make security` → `gosec ./...` (if available) - `make test` → `go test -v ./...` - `make check` → `make lint && make test` (standard validation pipeline)
