Installs, configures and runs last30days, an open-source research engine that searches Reddit, X, YouTube, Hacker News, Polymarket, GitHub and the web inside a recent time window and ranks what it finds by audience reaction. Use when someone asks "what are people saying about X", "research the last 30 days", "what does the community think of A vs B", "what has this company been up to this month", "set up last30days", or needs a cited brief on current opinion that training data cannot cover.
