What it is

/last30days is an AI agent skill and plugin that researches a topic across many platforms at once, including Reddit, X, YouTube, TikTok, Hacker News, Polymarket, GitHub and the web. It scores results by what people engage with (upvotes, likes, prediction-market money) rather than editorial or SEO ranking. An AI agent judge then synthesizes everything into a single brief. It runs on Claude Code, Codex, Cursor, Copilot, Gemini CLI, Grok, Claude Desktop, OpenClaw and other Agent Skills hosts.

Who it's for

  • Developers and AI practitioners who want to track what communities are discussing right now
  • People preparing for meetings, sales calls or trips who want a last-30-days picture of a person, company or place
  • Anyone comparing tools or finding emerging topics before they peak, using community signal instead of stale blog posts

Requirements

Requirements

  • A supported agent host: Claude Code, Grok, Codex, Cursor, Copilot, Gemini CLI or another Agent Skills host, claude.ai, Claude Desktop, or OpenClaw
  • Reddit, Hacker News, Polymarket and GitHub work with zero configuration
  • Your own API keys or browser sessions to unlock more sources such as X, YouTube and TikTok; the setup wizard walks through this
  • Claude Desktop: Python 3.12+ on PATH
  • claude.ai: 'Code execution and file creation' enabled under Capabilities

Setup

  1. Install on Claude Code (recommended)

    Add the marketplace and install the plugin. Updates arrive automatically via the marketplace.

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

  2. Install on Codex, Cursor, Copilot, Gemini CLI or other Agent Skills hosts

    Use the Agent Skills CLI. The -g flag installs globally for your user; drop it to scope to the current project.

    bash
    npx skills add mvanhorn/last30days-skill -g

  3. Install on Grok (xAI Build CLI)

    Add the repo as a marketplace source, then install by plugin name. Update later with grok plugin update last30days.

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

  4. Install on OpenClaw

    Install from ClawHub.

    bash
    clawhub install last30days-official

  5. Manual developer install

    Clone the repo and symlink the skill directory so the install stays in sync with your working tree.

    bash
    git clone https://github.com/mvanhorn/last30days-skill.git
ln -s "$(pwd)/last30days-skill/skills/last30days" ~/.claude/skills/last30days

Pros & cons

Pros

  • Pro:Reddit (with comments), Hacker News, Polymarket and GitHub work immediately with no configuration
  • Pro:Ranks by engagement signals across sources (upvotes, likes, prediction-market odds) rather than editorial or SEO relevance
  • Pro:Works across many hosts, including Claude Code, Codex, Cursor, Copilot, Gemini CLI, Grok, Claude Desktop and OpenClaw
  • Pro:A doctor command checks every source and prescribes exact fixes for missing keys, PATH problems or expired cookies

Cons

  • Con:Many sources (X, YouTube, TikTok and others) need your own API keys or browser sessions
  • Con:Claude Desktop does not share credentials with the Claude Code skill, and Windows support for the Desktop bundle is deferred
  • Con:Installing both the Claude Code marketplace plugin and the npx skills copy shows two /last30days entries, so use one install method per machine
