Say it with a schedule attached: 'every Friday, summarize what shipped and send it to the team channel.' The durable scheduler holds it, fires it, and reports completion or failure as a visible signal, forever, until you change it.
Anything you find yourself doing on a rhythm is a candidate: weekly reports, renewal checks, metric watches, pre-meeting briefings. Set once, then judge the output like you would a colleague's.
Durability is the quiet feature: restarts and deploys do not eat scheduled work, so 'every Friday' means every Friday, which is precisely what most automation cannot promise.
