A single Claude Code skill is cracking the top of GitHub Trending today, pulling 1,186 stars in 24 hours and pushing the project past 15,000 total stars since its January launch.

last30days-skill is an open-source research agent that runs as a /last30days command inside Claude Code or any OpenClaw-compatible environment. Type a topic, and it scans Reddit, X, Bluesky, YouTube, TikTok, Instagram, Hacker News, Polymarket, and the web — then returns a single grounded briefing with citations, engagement scores, and real quotes from the people paying attention.

What Makes It Different

Most "research agents" call a search API and hand back a list of links. last30days cross-references multiple signals and surfaces convergence: if three different platforms are independently buzzing about the same thing, the skill flags it. Polymarket integration adds real-money odds alongside community sentiment, giving a calibration layer that pure social listening misses.

The latest update (v2.9.5) added Bluesky/AT Protocol as a signal source, comparative mode (/last30 cursor vs windsurf runs three parallel passes and returns a side-by-side breakdown), and per-project config for teams.

Growing Ecosystem

The skill ships with marketplace plugin metadata for the Claude Code plugin ecosystem and supports watchlists for topics you want monitored on a schedule. The author integrated a Remotion video skill for generating demo reels directly from research output — a pattern that's spreading to other Claude Code skill developers.

With the Claude Code skills ecosystem expanding rapidly, last30days has become one of the go-to community benchmarks: when a new AI tool drops, the first /last30days briefing on it often appears on X within hours.
