# Contexts

karma has contexts support, which allows to add arbitrary key-value fields

to the error to ease debug.

Simplest usage is to add key-values for existing error:

```go

func bar(arg string) error {

    return fmt.Errorf("arg is invalid: %s", arg)

}

func foo(arg string) error {

    err := bar(arg)

    if err != nil {

        return karma.Describe("method", "bar").Reason(err)

    }

}

fmt.Println(foo("hello"))

// Output:

//

// arg is invalid: hello

// └─ method: bar

```
