Summarize every new video from a channel I follow

There's new activity on the YouTube channel [channel name]. If it isn't a new video upload, stop and do nothing. For the new video, read its title, description, and transcript. Summarize what it covers in [5] bullet points, with the claims, announcements, numbers, or product news that matter to me: [what you track this channel for, for example competitor launches or industry trends]. Call out anything new compared with what the channel has said before. Keep it under [150] words and include the video link.
