Hi Pavel, I can only speak as a community maintainer. However, from experience, trying to pack extra logic like that into modules results in the code becoming less reliable. The "check" parameter you've suggested is effectively duplicating the functionality of "when", while not being as flexible.
My alternative suggestion would be to split the "test" shell task (which you can set to always use `changed_when: False`) from the "update" shell task and use the pre-existing when controls to decide if the "update" shell task even needs to run. """ - name: Check record shell: record-is-present register: check changed_when: False - name: Add record shell: add-record register: result when: check.rc == 0 """ This also has the advantage that it's also very clear why things happened and you can access the output of both shell commands. While I do sometimes miss the "check" type logic that's available with Puppet, it can also cause confusion in and of itself, and is often a sign that something would be much better handled as a custom module rather than a shell task.
