Claude is smart, but it doesn't know what people are saying this week. Its training has a cutoff, so for anything current it's guessing. This fixes that. It's a free skill that makes Claude go search Reddit, X, YouTube, TikTok, Instagram, Threads, Bluesky, Pinterest, Hacker News, Polymarket, GitHub, and the web all at once before it answers, then hand you a summary built from what real people actually said in the last 30 days.

It's called Last 30 Days, it runs inside Claude Code, and it takes about 30 seconds to set up. Here's the exact link and the full guide.

The exact link

This is the one. It's the repo that shows up when you search "30 days skill," free and open source:

github.com/mvanhorn/last30days-skill

The full setup

  1. Open Claude Code. Start a new chat.
  2. Install it with one command. Paste this in and send it:
    /plugin marketplace add mvanhorn/last30days-skill
    That adds the skill and keeps it updated for you. (You can also just paste the GitHub link above and tell Claude to install it.)
  3. Use it. Type /last30days followed by your topic or question, like:
    /last30days best budget noise cancelling headphones

It searches every platform in parallel, then gives you a detailed answer ranked by what people actually engaged with, and at the end it shows you the exact platforms it pulled from.

What works right away, and what needs a key

Being honest so you're not surprised: the core sources work instantly with zero setup, and the big social ones need a quick (mostly free) add-on.

  • Free, no setup: Reddit with comments, Hacker News, Polymarket, and GitHub work the second you install it.
  • Free, one quick step: X/Twitter (a browser login) and YouTube (install yt-dlp).
  • Needs an API key: TikTok, Instagram, Threads, and Pinterest run through ScrapeCreators, which gives you 100 free credits to start, then pay as you go.

So you get real value out of the box from Reddit alone, and you can switch on the rest whenever you want the full sweep.

What to actually use it for

  • Meeting and people research. Run a name or company before a call and get what's been said about them recently.
  • Your daily news. Ask what's happening on a topic and get the real reactions, not a press release.
  • Comparing tools before you buy. "Is X or Y better right now" pulls live opinions from people who actually use them.
  • Trip and purchase planning. Real, recent feedback beats a 3-year-old blog post every time.
The reason this feels like a cheat code is that it swaps stale training data for what people are saying right now, ranked by what actually got attention. You stop guessing and start answering from the live internet, without leaving the chat.

Install it, then ask it about something you're about to buy or walk into. The first answer that pulls real opinions from this week will sell you on it.
