Last30

last30 — Research Any Topic from the Last 30 Days

Attribution: Simplified port of mvanhorn/last30days-skill (v2.9.5) by @mvanhorn. Original uses ScrapeCreators API for Reddit/TikTok/Instagram; this port uses free public APIs (Reddit JSON, HN Algolia, Brave Search) for a lightweight, zero-API-key setup.

Research any topic across Reddit, X/Twitter, Hacker News, YouTube, Polymarket, and the web. Surface what people are actually discussing, recommending, debating, and betting on right now.

Trigger Phrases

• /last30 [topic]
• research [topic]
• what's trending in [topic]
• [topic] vs [topic]
• /last30days [topic]

Prerequisites

• BRAVE_API_KEY env var must be set (web search)
• AUTH_TOKEN + CT0 env vars (optional, for X search via bird)
• summarize skill available for YouTube transcripts

Parse User Intent

2. QUERY_TYPE:
   • RECOMMENDATIONS — "best X", "top X", "what X should I use"
   • NEWS — "what's happening with X", "X news"
   • COMPARISON — "X vs Y", "X versus Y"
   • GENERAL — anything else

How It Works

1. Reddit — queries reddit.com/r/[subreddit]/search.json by relevance
2. X/Twitter — uses bird (xurl) for recent posts
3. Hacker News — queries hn.algolia.com API
4. YouTube — runs summarize skill for video transcripts
5. Polymarket — queries polymarket.com API for active prediction markets related to the topic
6. Web — Brave Search API

Results are scored by engagement signals, cross-platform convergence is detected, and a synthesis is generated with inline citations.
