A Golang linter that checks whether wrapped errors have a consistent format. The expected format has the message begin with the function call that last assigned a value to the wrapped error, e.g.:
_, err := fmt.Scanf("")
if err != nil {
return fmt.Errorf("fmt.Scanf: %w", err)
}
For examples of other scenarios check the testdata directory.
