The AI world reinvents itself every month. This skill keeps you current.
/last30days researches your topic across Reddit, X, YouTube, and the web from the last 30 days, finds what the community is actually upvoting, sharing, and saying on camera, and writes you a prompt that works today, not six months ago.
Three Headline Features
1. Open-class skill with watchlists. Add any topic to a watchlist -- your competitors, specific people, emerging technologies -- and /last30days re-researches it on demand or via cron. Designed for always-on environments like Open Claw. SQLite-backed with FTS5 full-text search.
2. YouTube transcripts as a 4th source. When yt-dlp is installed, /last30days automatically searches YouTube, grabs view counts, and extracts auto-generated transcripts from the top videos. A 20-minute review contains 10x the signal of a single post -- now the skill reads it. Inspired by @steipete's yt-dlp + summarize toolchain.
3. Works in OpenAI Codex CLI. Same skill, same engine, same four sources. Install to ~/.agents/skills/last30days and invoke with $last30days.
Plus: Bundled X search -- vendored Bird GraphQL client (MIT). No external CLI, no npm install, no API keys needed. Just Node.js 22+ and your browser cookies.
