# What is an Action?

Actions are reusable code segments that complete a specific task

Actions are the base unit of code used in unSkript.  Actions take [inputs](/unskript-documentation/actions/actions/action-configuration/action-inputs.md), complete a task, and [output](/unskript-documentation/actions/actions/action-configuration/action-output.md) a result.

unSkript comes with hundreds of [Prebuilt Actions](/unskript-documentation/actions/action-list.md) that are ready for immediate use.

### Types of Actions

* **Connector Actions**: Connector Actions interface with an external tool (for example [AWS](/unskript-documentation/connnecting/connectors/aws/action_aws.md) or [Datadog](/unskript-documentation/connnecting/connectors/datadog/action_datadog.md)), and performs an Action with that tooling.
  * Connector Actions are added by searching in the right navigation.

* **Glue Actions:** Glue Actions are Python code used to manipulate and work with the data. Glue Actions are created from the "Add" button at the top of the RunBook.  
  * Simplify a data output to a different format.
  * Chart results
  * Build interactive selections
