Introduction

CrewAI provides the ability to replay from a task specified from the latest crew kickoff. This feature is particularly useful when you’ve finished a kickoff and may want to retry certain tasks or don’t need to refetch data over and your agents already have the context saved from the kickoff execution so you just need to replay the tasks you want to.

You must run crew.kickoff() before you can replay a task. Currently, only the latest kickoff is supported, so if you use kickoff_for_each, it will only allow you to replay from the most recent crew run.

Here’s an example of how to replay from a task:

​
Replaying from Specific Task Using the CLI

To view the latest kickoff task_ids use:

Once you have your task_id to replay, use:

crewai replay -t <task_id>

Ensure crewai is installed and configured correctly in your development environment.

​
