Last 30 Days

last30days

Research what people actually say about any topic in the last 30 days. Pulls posts and engagement from Reddit, X, YouTube, TikTok, Hacker News, Polymarket, GitHub, and the web. Includes a doctor health check to diagnose broken or missing sources.

Install

Run this in your project folder. It works with Claude Code, Cursor, Codex and dozens of other agents.

$ npx skills add mvanhorn/last30days-skill --skill last30days

Needs Node.js. Add -g to install for every project, or -a claude-code to skip the agent picker.

How to use Last 30 Days

Once it's installed, Claude reads this skill on its own whenever a request matches what it's for, so you don't have to mention it by name. In Claude Code you can also run it directly by typing /last30days.

It includes scripts that Claude may run on your computer, so skim them on GitHub before you install.
