# Evaluators

> Built-in and external evaluators for Agent Control.

Evaluators determine how controls match. Agent Control ships with built-in evaluators and supports external ones.

## Built-in evaluators

* `regex`
* `list`
* `json`
* `sql`

Install built-ins:

```bash theme={null}
pip install agent-control-evaluators
```

## External evaluators

Galileo Luna-2 is available as an extra:

```bash theme={null}
pip install agent-control-evaluators[galileo]
```
