# Overview

The Prefect task library is a constantly growing list of pre-defined tasks that provide off-the-shelf functionality for working with a wide range of tools anywhere from shell script execution to kubernetes job management to sending tweets. A majority of the task library is community supported and thus opens the door for users who want to contribute tasks for working with any number of tools. Tasks in the task library are created with a specific goal in mind such as creating a Kubernetes job with CreateNamespacedJob or invoking an AWS lambda function with LambdaInvoke.

Below is a table showcasing some of the tasks that have been contributed to the task library for interfacing with varying tools and services that users have deemed useful. For a full list of tasks in the library and more information on how to use them visit the API reference documentation for the prefect.tasks module.

Tasks marked with the Verified badge have been reviewed and approved by Prefect.

# Task library in action

Just like any other Prefect task, tasks in the task library can be used by importing and adding them to your flow.

Keyword arguments for tasks imported from the task library can either be set at initialization for reuse purposed or optionally set and overwritten when defining the flow.
