In the AI era, getting "real" and "live" information is becoming increasingly difficult. Google's search results are filled with SEO-optimized spam, while social platforms like Reddit, X (Twitter), YouTube, and TikTok act as "walled gardens," creating disconnected silos of information.
Today, we're featuring last30days-skill (GitHub 28.8k Stars), an open-source project designed to break this deadlock. It isn't a traditional search engine; it's a new type of insight engine led by an AI Agent.
Core Philosophy: Searching People, Not Websites
Project creator mvanhorn notes that Google aggregates editors and SEO writers, while /last30days searches real people and their active engagement.
Its uniqueness lies in:
- Bridging Walled Gardens: No single AI has native access to all social platforms. Google doesn't touch Reddit comments; ChatGPT can't search X.
/last30daysuses agents to bridge these gaps. - Scored by Real Engagement: Information isn't ranked by SEO algorithms but by Reddit upvotes, X likes, YouTube views, and even real money backed by Polymarket odds.
- AI Agent Synthesis: It doesn't just list links. An AI agent judge synthesizes fragmented data (posts, replies, transcripts, commits) into one brief, grounded summary.
What can it do for you?
1. Pre-Meeting Intelligence
If you have a meeting with a CEO tomorrow, Google might show you a LinkedIn profile from 2023.
Command: /last30days [Name]
It tells you what they're actually doing this month: their latest X debates, GitHub PRs, and podcast transcripts.
2. Truth Mining & Tool Comparisons
Want the real verdict on a new open-source tool?
Command: /last30days Tool-A vs Tool-B
It skips the generic "Top 10" blog posts and shows you the raw developer sentiment and top-voted comments from Reddit and Hacker News.
3. Real-time Market & Crisis Analysis
Leveraging real money from prediction markets like Polymarket.
Search: /last30days [Major Event]
