The Problem That Needed Solving
Matt Van Horn noticed something frustrating: the prompts that make Claude Code powerful change constantly. What worked last month is stale today. Meanwhile, the best conversations about prompting techniques, tool configurations, and workflow hacks are happening in real time on X, Reddit, and GitHub — but nobody can keep up with all of them. So Van Horn built a Claude Code skill called "last 30 days" that solves this by using trending data from those platforms as the starting point for your prompts.
The core insight is simple but effective: instead of trying to stay current yourself, let the tool ingest what's being discussed right now and use that as context for whatever you want to build or write.
How It Works
The skill requires three things: a Claude Code account (which you already have if you're using the tool), an OpenAI key (because OpenAI has a deal with Reddit that provides Reddit access), and an X AI key (since you can't search X using your personal account). Last 30 days pulls all three together and searches X, Reddit, and the web for content from only the last 30 days.
