Ask Claude what the internet actually said

last30days is a free (MIT) skill by Matt Van Horn. Type /last30days and a question: it searches Reddit, Hacker News, Polymarket and GitHub with no API keys, scores posts by real engagement and writes a brief with a link on every claim, ending in "choose X if".

1 Install

In Claude Code:

/plugin marketplace add mvanhorn/last30days-skill
/plugin install last30days

Codex, Cursor, Gemini CLI and other agent hosts:

npx skills add mvanhorn/last30days-skill -g

The repo on GitHub. Needs Python 3.12+. X, YouTube, TikTok and more sources unlock after its setup (some need keys or browser sign-ins).

2 The exact command from the reel

/last30days Claude Code vs Codex --deep

Our run (18 Oct 2026, Claude Code, Sonnet 5.5): 28 Reddit threads, 24 Hacker News stories, 10 Polymarket markets and GitHub, about 5 minutes, about $0.61 at API prices (we were on a Max plan). YouTube was rate-limited that run, X was off. Treat sentiment as directional, and open the links.

/last30days is Claude Max worth it --quick
/last30days <person you meet tomorrow>
/last30days what's exploding in AI agents?
/last30days <thing you are about to buy> --quick

--quick is faster with fewer sources; --deep reads more. Our "is Claude Max worth it --quick" run took 65 seconds.

4 Good to know

It saves each brief as a markdown file in ~/Documents/Last30Days. Check quotes against the linked threads before you repeat them: in our run one Reddit thread about a third-party plugin was summarised as a Claude Code feature.
