# Customizing Lifecycle Hooks

## Background

{% content-ref url="/pages/ANLbxIN4T0Q4YF2llfer" %}
[Lifecycle Hooks](/core-concepts/agent/lifecycle-hooks.md)
{% endcontent-ref %}

## Customizing

1. Each workflow provides a `lifecycle-hooks.py` script that will be applied when the workflow runs.
2. It can be accessed in the following location:

```bash
.stoobly/services/<SERVICE-NAME>/<WORKFLOW-NAME>/lifecycle_hooks.py
```

3. Modifications to this file will not be overriten when the `service create` command is re-run.
