`post` will be pushed into a `poststeps` stack lazily when the action's `pre` or `main` execution passed `if` condition check and about to run, you can't have an action that only contains a `post`, we will pop and run each `post` after all `pre` and `main` finished. `post` will be pushed into a `poststeps` stack lazily when the action's `pre` or `main` execution passed `if` condition check and about to run, you can't have an action that only contains a `post`, we will pop and run each `post` after all `pre` and `main` finished.
