Harvest Monitor
Track changes on web pages over time. Compare current content against cached versions to detect updates, new releases, breaking changes, and documentation modifications.
Usage
# Monitor a page for changes
/harvest-monitor https://docs.example.com/changelog
# Compare against last cached version
/harvest-monitor https://docs.example.com/api --diff
# Track multiple pages
/harvest-monitor --watchlist ~/.claude/cache/agents/harvest/watchlist.json
How It Works
- Fetch current page content
- Check cache for previous version
- Compute diff (content-level, not HTML-level)
- Categorize changes (added, removed, modified)
- Report significant changes
- Update cache with current version
Output
# Change Report: [URL]
> Checked: [timestamp]
> Previous: [cached timestamp]
> Status: CHANGED / NO CHANGE
## Changes Detected
