last30days: An Agent Skill That Searches People, Not Editors
Canonical version: last30days: An Agent Skill That Searches People, Not Editors.
Matt Van Horn (co-founder of the June oven and an early member of the team that became Lyft) has been building in open source lately. One of his projects is last30days, an AI agent skill that researches any topic across the places people actually talk.
Google aggregates editors. last30days searches people.
What it does
Give it a topic (a person, a company, a product, a comparison) and it searches Reddit, X, YouTube, Hacker News, Polymarket, GitHub, TikTok, Instagram, Bluesky, Threads, and grounded web search in parallel. Then it:
- ranks results by engagement: upvotes, likes, view counts, and betting odds
- merges duplicate stories, so an item that surfaces on Reddit, X, and YouTube becomes one entry
- has Claude write a cited, ranked brief that you can question with follow-ups
It resolves entities up front (handles, subreddits, repos), scores results by engagement, relevance, and freshness, and can output shareable dark-mode HTML briefs or accumulate findings in a local SQLite database for trend monitoring. The public sources (Reddit, HN, Polymarket, GitHub) are free by default; the others need your own API keys. It's MIT-licensed, has no tracking, and keeps everything on your machine.
Why I like it
I like that it ranks findings by community engagement (upvotes, betting odds) instead of search ranking, so it shows a topic from a different angle than Google does. And because it's packaged as an agent skill, it runs in Claude Code and 40+ other harnesses.
Install in Claude Code is a one-liner:
/plugin marketplace add mvanhorn/last30days-skill
Coming to the Obsidian Starter Kit
I'm adapting a variant of this idea for the Obsidian Starter Kit soon: a research skill tuned for the OSK vault, so the findings land as proper notes in your PKM instead of a throwaway chat. If you want that the moment it ships (along with the rest of the OSK skill suite), grab the kit here: 👉 https://www.store.dsebastien.net/product/obsidian-starter-kit
That's it for today! ✨
