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](https://github.com/openclaw/openclaw). 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](https://x.com/steipete)'s yt-dlp + [summarize](https://github.com/steipete/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.
