send-a-notification

Tell a person something through transom that needs no answer: a finished task, a status change, an alert, or its resolution. Covers choosing an urgency honestly, a key so a later message replaces an earlier one, links with titles, a Markdown body, images, and a time to live. Use when work should reach someone's phone or browser and nobody has to decide anything; to ask for a decision, use the ask-a-question skill.
