What it does
/last30days is an installable “skill” for AI agent hosts (Claude Code, Cursor, Copilot, etc.) that researches any topic across a dozen platforms—Reddit, X, YouTube, TikTok, Hacker News, Polymarket, GitHub, Bluesky, and more—then synthesizes a ranked brief. It scores results by social engagement (upvotes, likes, views, or prediction-market odds) rather than SEO authority. You type /last30days Peter Steinberger or /last30days OpenClaw vs Hermes and get back a summary of what actually happened in the last month, with citations.
The interesting bit
The v3 engine doesn’t just keyword-search. It first runs a “pre-research brain” that resolves your topic into the right handles, subreddits, hashtags, and GitHub profiles before firing any API call—so “Paperclip” becomes @dotta, and “Peter Steinberger” becomes @steipete plus r/ClaudeCode. It also has a second scoring judge for humor and virality, so the best one-liners from X and Reddit surface in a “Best Takes” section instead of getting buried by relevance ranking.
Key highlights
- Bring-your-own-keys model: Reddit, HN, Polymarket, and GitHub work immediately; a 30-second setup wizard unlocks X, YouTube, TikTok, etc. after first run.
- Shareable HTML briefs:
--emit=htmlexports a self-contained, dark-mode, print-friendly file with inline CSS, no JavaScript, offline-ready. - Cross-source deduplication: v3 merges the same story across Reddit, X, and YouTube into single clusters via entity-based overlap detection.
- Parallel comparisons: “A vs B” queries run in one pass with entity-aware subqueries, down from 12+ minutes to ~3 minutes in v3.
- Auto-discovered competitors:
--competitorsflag triggers web search to find top 2 peers, then fans out 3 full pipelines in parallel for a merged comparison.
Caveats
- Requires installing into a supported agent host (Claude Code recommended); not a standalone CLI tool, though direct engine use is possible.
- Many sources need your own API keys or browser sessions—X, YouTube, TikTok, Instagram, Threads, Pinterest, and Bluesky are not free out-of-the-box.
- The README is long on examples and short on architecture docs; the actual runtime spec is in
skills/last30days/SKILL.md, not the README.
Verdict
Grab this if you do pre-meeting research, competitive intelligence, or trend monitoring and you’re already living inside Claude Code or Cursor. Skip it if you want a polished web app or can’t be bothered to manage API keys for half a dozen social platforms.
