+# Smithy Go Style Guide
+
+* [Introduction](#introduction)
+* [Guidelines](#guidelines)
+  * [Pointers to Interfaces](#pointers-to-interfaces)
+  * [Don't Panic](#dont-panic)
+
+## Introduction
+
+Styles are the conventions that govern our code. The term style is a bit of a
+misnomer, since these conventions cover far more than just source file
+formatting—gofmt handles that for us.
+
+The goal of this guide is to manage this complexity by describing in detail the
+Dos and Don'ts of writing Go code at Uber. These rules exist to keep the code
+base manageable while still allowing engineers to use Go language features
+productively.
+
+This documents idiomatic conventions in Go code that we follow at Smithy. A lot
+of these are general guidelines for Go, while others extend upon external
+resources:
+
+1. [Effective Go](https://go.dev/doc/effective_go)
+2. [Go Common Mistakes](https://go.dev/wiki/CommonMistakes)
+3. [Go Code Review Comments](https://go.dev/wiki/CodeReviewComments)
+4. [Uber Go Style Guide](https://github.com/uber-go/guide/blob/master/style.md)
+
+## Guidelines
+
+### Pointers to Interfaces
+
+You almost never need a pointer to an interface. You should be passing
+interfaces as values—the underlying data can still be a pointer.
+
+An interface is two fields:
+
+1. A pointer to some type-specific information. You can think of this as
+   "type."
+2. Data pointer. If the data stored is a pointer, it’s stored directly. If
+   the data stored is a value, then a pointer to the value is stored.
+
+If you want interface methods to modify the underlying data, you must use a
+pointer.
+
+Pointer to interfaces are quite tedious to dereference.
+
+<table>
+<thead><tr><th>Bad</th><th>Good</th></tr></thead>
+<tbody>
+<tr><td>
+
+```go
+type (
+	Shape interface {
+            Area() float64
+    }
+
+	Circle struct {
+            Radius float64
+	}
+)
+
+func (c *Circle) Area() float64 {
+    return 3.14 * c.Radius * c.Radius
+}
+
+func printArea(s *Shape) {
+    fmt.Println((*s).Area()) // Dereferencing pointer to interface
+}
+
+func main() {
+    c := &Circle{Radius: 5}
+
+    var s Shape = c // Assign Circle to Shape
+    printArea(&s)   // Passing pointer to interface (bad)
+}
+```

+
+```go
+type (
+    Shape interface {
+            Area() float64
+    }
+
+    Circle struct {
+            Radius float64
+    }
+)
+
+func (c *Circle) Area() float64 {
+    return 3.14 * c.Radius * c.Radius
+}
+
+func printArea(s Shape) {
+    fmt.Println(s.Area()) // No need to dereference
+}
+
+func main() {
+    c := &Circle{Radius: 5}
+
+    var s Shape = c // Assign Circle to Shape
+    printArea(s)    // Passing interface by value
+}
+```

+
+### Don't Panic
+
+Code running in production must avoid panics. Panics are a major source of
+[cascading failures](https://en.wikipedia.org/wiki/Cascading_failure).
+If an error occurs, the function must return an error and
+allow the caller to decide how to handle it.
+
+<table>
+<thead><tr><th>Bad</th><th>Good</th></tr></thead>
+<tbody>
+<tr><td>
+
+```go
+func run(args []string) {
+  if len(args) == 0 {
+    panic("an argument is required")
+  }
+  // ...
+}
+
+func main() {
+  run(os.Args[1:])
+}
+```
+
+</td><td>
+
+```go
+func run(args []string) error {
+  if len(args) == 0 {
+    return errors.New("an argument is required")
+  }
+  // ...
+  return nil
+}
+
+func main() {
+  if err := run(os.Args[1:]); err != nil {
+    fmt.Fprintln(os.Stderr, err)
+    os.Exit(1)
+  }
+}
+```
+
+</td></tr>
+</tbody></table>
+
+Panic/recover is not an error handling strategy.
+A program must panic only when
+something irrecoverable happens such as a nil dereference.
+An exception to this is
+program initialization: bad things at program startup that
+should abort the program may cause panic.
+
+```go
+var _statusTemplate = template.Must(template.New("name").Parse("_statusHTML"))
+```
+
+Even in tests, prefer `t.Fatal` or `t.FailNow` over panics to ensure that the
+test is marked as failed.
+
+<table>
+<thead><tr><th>Bad</th><th>Good</th></tr></thead>
+<tbody>
+<tr><td>
+
+```go
+// func TestFoo(t *testing.T)
+
+f, err := os.CreateTemp("", "test")
+if err != nil {
+  panic("failed to set up test")
+}
+```
+
+</td><td>
+
+```go
+// func TestFoo(t *testing.T)
+
+f, err := os.CreateTemp("", "test")
+if err != nil {
+  t.Fatal("failed to set up test")
+}
+```
+
+</td></tr>
+</tbody></table>
+
+Panics should always be reported in a way that
+the team is aware that a service is having such
+issue. A tool like [Sentry](https://sentry.io/welcome/)
+is excellent to report such extreme issues and make
+sure that the team is notified to resolve the root cause.
+
+[It's useful to see the stacktrace at the moment
+of a process panicking](https://yourbasic.org/golang/recover-from-panic/).
+Logs, Traces and Metrics should be enriched with the latter.
