Given that CircleCI does not provide us with configurations options, lets say I wish to run some specific commands based on some parameters sent to the build via API. I would like to be able to stop the build once that is complete - the build result reflecting the exit code of that command. This way, I do not have to IF-GATE the rest of my circle.yml to avoid those steps when this parameter is sent.
Right now, we can fail the build at that point but we cannot post a success from that build and still avoid successive steps.
