The lesson
Announce with the name, the three things it can see, and two imperatives, then let the video carry the rest.
The post reads "Introducing Linear Agent." then "Built directly into Linear and accessible everywhere, it understands your roadmap, issues, and code." and ends "Ask anything. Command everything." Below it sits a 00:51 video whose visible image is a dark screen with a faint angled panel.
The format needs a known brand and a strong video, so a newcomer should add one concrete example. Keep the plain name, the nouns it understands and the closing pair of commands.
