Workflows cannot alter the state of the parent shell

[joshnesbitt]

If a workflow contains commands that would alter the state of the current shell (e.g. a cd command), after exiting the state of the parent shell would remain unchanged. This is intended as there are cases where you may want to perform a chain of commands and leave the current context unchanged. Might add support for this in the future as I can see it being a blocker for certain workflows.
