What problem does it solve? Monitoring external sources like RSS feeds, GitHub repos, or JSON APIs for new items requires tracking what has already been seen. This Skill provides ready-made polling scripts that deduplicate results with persistent watermark files, so cron jobs and agents only report genuinely new items. ## Core Features & Use Cases - RSS/Atom Watching: Poll any RSS 2.0 or Atom feed and emit only new entries, deduplicated by guid or id. - GitHub Monitoring: Watch issues, pull requests, releases, or commits for any repository, with optional GITHUB_TOKEN authentication to avoid rate limits. - Generic JSON API Polling: Poll any JSON endpoint returning a list of objects, with configurable id fields, dotted items paths, and custom headers. - Use Case: Schedule a cron job that runs watch_rss.py every 15 minutes against a news feed; the agent summarizes and delivers only new headlines, staying silent when nothing changed. ## Quick Start Ask the agent to watch the Hacker News RSS feed every 15 minutes and notify you only when new stories appear.
