Have you had experience working with post-hook or similar mechanisms for performing actions after the main event?

Yes, I have experience with post-hook or similar mechanisms. A post-hook is a script or function that automatically executes after the completion of a main event or operation. For example, in CI/CD systems, after a successful deployment, a post-hook can be configured to send a notification to Slack or clean up temporary files. Kubernetes has lifecycle hooks, where postStart and preStop allow actions to be performed during container startup or shutdown.

A simple example of a post-hook in Git, which runs after a commit:

# In the .git/hooks/post-commit file
#!/bin/sh
# Send a notification after commit
curl -X POST -d "commit=$(git log -1 --oneline)" http://example.com/notify

This approach helps automate tasks that need to be performed after the main process.
