An AI agent-led search engine scored by upvotes, likes, and real money - not editors.
This README tracks the current v3 pipeline. The runtime skill spec lives in skills/last30days/SKILL.md, which is the source of truth for the latest command and setup behavior.
Claude Code (recommended — auto-updates via marketplace):
/plugin marketplace add mvanhorn/last30days-skill
/plugin install last30days
Codex, Cursor, Copilot, Gemini CLI, or any of 50+ Agent Skills hosts:
npx skills add mvanhorn/last30days-skill -g
(-g installs globally for your user, available across all projects. Drop it to scope per-project.)
More install options (claude.ai web, OpenClaw, manual) in the Install section below.
Zero config. Reddit, HN, Polymarket, and GitHub work immediately. Run it once and the setup wizard unlocks X, YouTube, TikTok, arXiv, Techmeme, and more in 30 seconds.
Reddit upvotes. X likes. YouTube transcripts. TikTok engagement. Polymarket odds backed by real money and insider information. That's millions of people voting with their attention and their wallets every day. /last30days searches all of it in parallel, scores it by what real people actually engage with, and an AI agent judge synthesizes it into one brief.
Google aggregates editors. /last30days searches people.
You can't get this search anywhere else because no single AI has access to all of it. Google search doesn't touch Reddit comments or X posts. ChatGPT has a deal with Reddit but can't search X or TikTok. Gemini has YouTube but not Reddit. Claude has none of them natively. Each platform is a walled garden with its own API, its own tokens, its own auth. But you can bring your own keys and browser sessions, and suddenly an AI agent can search all of them at once, score them against each other, and tell you what actually matters.
That's the unlock. Not one better search engine. A dozen disconnected platforms, bridged by an agent.
/last30days Peter Steinberger
You have a meeting tomorrow. You Google them. You get their LinkedIn from 2023. /last30days gives you what they're actually doing this month: joined OpenAI to work on Codex, fighting Anthropic's ban on third-party agents, shipping 23 PRs at 85% merge rate, building "LobsterOS" for cross-device agent control, and r/ClaudeCode hit 569 upvotes debating whether he's a hero or "insufferable." Scattered across X posts, Reddit threads, YouTube transcripts, and GitHub commits. None of it was on Google.
I built it to keep up in AI. Everything changes every day and the Reddit and X nerds are always on top of it first. I needed better prompts, and the training data was always months behind what the community had already figured out.
But it turned into something bigger. Now I run it before a sales call to know the last 30 days truth about a business. Before a meeting to read someone's recent tweets and podcast transcripts. Before a Disney World trip to know which rides are closed and what the community says about Genie+. Before I build anything to know what problems people are actually hitting.
If you're meeting with a CEO, have you read all their tweets and YouTube transcripts from the last 30 days? I have.
| Source | What the people tell you |
|---|---|
| The unfiltered take. Top comments with real upvote counts, free, no API key. The real opinions that Google buries. | |
| X / Twitter | The hot take, the expert thread, the breaking reaction. First to know, first to argue. |
| YouTube | The 45-minute deep dive. Full transcripts searched for the 5 quotable sentences that matter. |
| TikTok | The creator reaching 3.6M people with a take you'll never find on Google. |
| Instagram Reels | The influencer perspective with spoken-word transcripts. The visual culture signal. |
| Hacker News | The developer consensus. 825 points, 899 comments. Where technical people actually argue. |
| Polymarket | Not opinions. Odds. Backed by real money. 96% confidence on album sales. 4% on an acquisition. |
| GitHub | For people: PR velocity, top repos by stars, release notes. For topics: issues and discussions. |
| Digg | Curated story clusters from Digg's AI 1000 leaderboard (~1000 high-signal AI accounts on X), with attributable inline quotes (no X auth required). Auto-enabled when digg-pp-cli is on PATH. |
| arXiv | The papers behind the hype. New research in the window, free, no API key. Auto-enabled when arxiv-pp-cli is on PATH (first-run setup installs it). |
| Techmeme | The tech-news editorial layer, date-windowed to your 30 days. Free, no API key. Auto-enabled when techmeme-pp-cli is on PATH (first-run setup installs it). |
| The professional signal. Posts and articles, with articles weighted as high signal. | |
| Meta Ads | What a brand is paying to say. Live Meta ad creatives launched this month, with copy, promo codes, and spoken transcripts. |
| StockTwits | Trader sentiment. Auto-activates when your topic is a ticker or crypto. |
| Threads | The post-Twitter text layer. Conversations from creators and brands. |
| Visual discovery. Pins, saves, and comments on products and ideas. | |
| Xiaohongshu (RED) | Chinese lifestyle, product, and creator signals. Requested explicitly with --search xhs when a logged-in x-mcp browser plugin or xiaohongshu-mcp service is running locally. |
| Bluesky | The decentralized social layer. AT Protocol posts from the post-Twitter migration. |
| Perplexity | Controlled Agent API synthesis, OpenRouter Sonar fallback, raw Search API rows, and explicit Deep Research. |
| Web | The editorial coverage, the blog comparisons. One signal of many, not the only one. |
Community contributors keep adding more. Truth Social and other niche sources are in the engine with more on the way.
A Reddit thread with 1,500 upvotes is a stronger signal than a blog post nobody read. A TikTok with 3.6M views tells you more about what's culturally relevant than a press release. Polymarket odds backed by $66K in volume are harder to argue with than a pundit's guess.
The synthesis ranks by what real people actually engaged with. Social relevancy, not SEO relevancy.
Before a meeting. /last30days Peter Steinberger - joined OpenAI's Codex team, fighting Anthropic's ban on third-party agents, 23 PRs merged at 85% merge rate on GitHub, building LobsterOS for cross-device agent control. r/ClaudeCode: "Ever since OpenClaw released, it was widely known that if you run it through anything other than the API, you were gonna get banned eventually" (227 upvotes). That's not on LinkedIn.
To read hiring signals. /last30days Listen Labs --hiring-signals - current jobs and careers pages become cited evidence for focus shifts: hiring into enterprise security, customer success, infrastructure, or product expansion. The report says what the hiring appears to signal, not what the roadmap will ship.
To find the topic before it peaks. Ask /last30days what's exploding in AI agents? and the skill switches to discovery mode: the engine sweeps Reddit category listings, Hacker News front/best stories, Digg's AI 1000 feed, and X when authenticated; your agent judges the nominations (names, junk filtering, content-worthiness) and writes podcast / X-article angles; then you get 5-10 velocity-ranked topics. Every result includes cross-source numbers, a momentum label, and a ready-to-run /last30days "<topic>" follow-up.
When something drops. /last30days Kanye West - UK blocked his visa, Wireless Festival canceled, sponsors fled. But BULLY debuted #2 on Billboard. Fantano came back from his "Yay sabbatical" to review it (653K views). SoFi Homecoming brought out Lauryn Hill and Travis Scott for 44 songs. Polymarket: "Will Kanye tweet again?" 86% Yes. 23 Reddit threads, 17 YouTube videos, 86K upvotes.
To compare tools. /last30days OpenClaw vs Hermes vs Paperclip - "These aren't competitors, they're layers." OpenClaw is the executor (351K GitHub stars, live), Hermes is the self-improving brain (31K stars), Paperclip is the org chart (49K stars). Star counts pulled live from the GitHub API, not stale blog posts. Side-by-side table with architecture, memory, security, best-for. Per @IMJustinBrooke: "OpenClaw = Charmander, Hermes = Charizard."
To understand the world. /last30days Iran vs USA - Day 38 of the war. Trump's Tuesday deadline for Iran to reopen the Strait of Hormuz. Two US warplanes downed. Oil at $126/barrel. The IEA called it "the largest supply disruption in the history of the global oil market." Polymarket: ceasefire by Dec 31 at 74%. 27 X po
