# Attribute
## Introduction
A class that publishes a setter for an instance variable invites
client classes to become too intimate with its inner workings, and in
particular with its representation of state.
The same holds to a lesser extent for getters, but Reek doesn't flag those.
## Example
Given:
```ruby
class Klass
attr_accessor :dummy
end
```
Reek would emit the following warning:
```
reek test.rb
test.rb -- 1 warning:
[2]:Attribute: Klass#dummy is a writable attribute
```
## Support in Reek
This detector raises a warning for every public `attr_writer`,
`attr_accessor`, and `attr` with the writable flag set to `true`.
Reek does not raise warnings for read-only attributes.
## Configuration
_Attribute_ supports only the [Basic Smell Options](Basic-Smell-Options.md).
