last30days is an open-source Agent Skill (mvanhorn/last30days-skill) that searches a person or topic across a dozen walled-garden platforms and compiles a 30-day briefing. Instead of link-based ranking like Google's PageRank, it uses crowd-attention signals: Reddit and Hacker News upvotes, X likes, YouTube podcast transcripts, TikTok reach, GitHub PR merge rates, Polymarket real-money odds, arXiv papers, and Techmeme. Its key technical unlock is BYOK (Bring Your Own Keys): users supply API keys and browser sessions, and an AI agent uses those credentials to query all platforms simultaneously—something no single AI can do natively. It runs on 50+ Agent Skills hosts including Claude Code, Codex, Cursor, Copilot, and Gemini CLI; Reddit, HN, Polymarket, and GitHub need no API key. The project hit GitHub Trending #1 with 271 stars in a day and frames itself as a new paradigm: not a bigger search engine, but an agent bridging fragmented platforms with crowd attention as the ranking signal.
