Workflows/Jobs/etc… are stateful processes that can have any number of open resources. These resources need to be closed whenever the job/workflow that contains it is closed, no matter what the circumstances, and _especially_ on cancellation. There are a number of open tickets on this. [https://discuss.circleci.com/t/cancelled-build-post-hook-commands/5995](https://discuss.circleci.com/t/cancelled-build-post-hook-commands/5995) [https://discuss.circleci.com/t/support-scriptable-teardown-section-in-circle-yml/1703](https://discuss.circleci.com/t/support-scriptable-teardown-section-in-circle-yml/1703) [https://discuss.circleci.com/t/create-value-cancelled-for-run-s-when/12231](https://discuss.circleci.com/t/create-value-cancelled-for-run-s-when/12231) None of which has any response. What’s the status? ---

Sounds like a good hook to have. Have a look at `circleci.com/ideas` to see if it has been proposed already - and if not, please do add an idea. The forum does not automatically funnel ideas into the pot, as far as I know.
