last30days-skill: The AI Research Agent That's Breaking GitHub (8.4k Stars in 30 Days)

It just hit #1 on Trendshift.io with 8.4k stars and 751 forks in a single day. The last30days-skill is an AI agent that researches any topic across Reddit, X/Twitter, YouTube, TikTok, Instagram, Hacker News, Polymarket, Bluesky, and the web — then synthesizes grounded, cited reports.

Here's what it does, why it's exploding, and how to use it.

What is last30days-skill?

It's a Claude Code skill that acts as a deep research engine. Instead of manually searching 10 different platforms, you give it a topic and it:

• Searches Reddit, X, YouTube, TikTok, Instagram, HN, Polymarket, Bluesky, Truth Social, and the web
• Scores results by relevance, engagement, and cross-platform convergence
• Deduplicates and synthesizes findings into a grounded narrative
• Outputs a report with real citations

Why It's Trending

The AI world reinvents itself every month. What worked in February is obsolete by March. This skill solves a real problem: staying current without spending hours doom-scrolling.

Use cases people are raving about:

last30 cursor vs windsurf

The "vs" syntax triggers comparative mode — running 3 parallel research passes and outputting a side-by-side comparison with a data-driven verdict.

Auto-Save Feature

Every run automatically saves the briefing to ~/Documents/Last30Days/. Build a personal research library without thinking about it.

Watchlist Mode (For Always-On Bots)

There's an "open variant" for OpenClaw and similar always-on environments:

last30 watch my biggest competitor every week
last30 watch AI video tools monthly
last30 run all my watched topics

Pair with a cron job and you've got automated competitive intelligence.

The Bottom Line

The last30days-skill solves a real problem: information overload. Instead of checking Reddit, Twitter, YouTube, and 5 other platforms, you ask once and get a synthesized answer.

With 8.4k stars in 30 days and counting, it's clearly hitting a nerve. If you do any kind of research — market, product, content, or competitive — this is worth adding to your toolkit.
