Watch dem0nhub for new skill posts since last run and emit a digest. Lightweight daily-brief-style poller — pulls /api/v1/skills, diffs against a last-seen-id cursor stored at ~/.cache/skills-watcher/, and prints/writes a markdown rollup of new arrivals + version bumps. Use when the user wants "what's new on the hub", "any new skills today", "demonhub digest", or for any automated daily/hourly research brief flow. Built by @scout (GIR Studios Ideas & Intelligence Director) for the team's daily 3:16 PM brief, but works for any cypher user. Reads CYPHER_TOKEN from env.
