get_best_times
Best times to post
Reads only · changes nothing, and needs no approval.
What it does
Posting slots (weekday × hour, UTC) ranked by this workspace's own past engagement. signal says what the order is worth: none means no engagement is recorded and the order is arbitrary; thin means some slots rest on one or two posts (samples); ok means three or more each.
Arguments
