GitHub - mvanhorn/last30days-skill: AI agent skill that researches any topic across Reddit, X, YouTube, HN, Polymarket, and the web - then synthesizes a grounded summary

last30days is a Claude Code skill (also compatible with Codex CLI and Gemini CLI) that researches any topic across Reddit, X, Bluesky, YouTube, TikTok, Instagram, Hacker News, Polymarket, and the web from the past 30 days. It uses a two-phase search architecture with multi-signal relevance scoring, cross-platform convergence detection, and engagement-weighted ranking to synthesize grounded summaries with real citations. Version 2.9.5 adds Bluesky/AT Protocol support, a comparative mode for side-by-side tool comparisons, per-project .env config, and 455+ tests. The skill supports watchlists, scheduled briefings, SQLite history, and various web search backends. It takes 2–8 minutes per run and is especially useful for prompt research, trend discovery, product research, and current events monitoring.
