SKILL: Revenue Monitor
Purpose
Track daily revenue across Gumroad, KDP, and Etsy. Alert on anomalies (sales spikes, drops, or zero-revenue days). Generate daily and weekly summaries. Make sure no sale goes unnoticed and no revenue problem goes undetected.
Configuration (Set Once)
Check skills/revenue-monitor/config.json. If not present, ask:
- Gumroad: Do you have a Gumroad API access token? (Settings → Advanced → API)
- KDP: Do you have KDP sales tracking set up? (Manual CSV export or AgentReach session)
- Etsy: Do you have an Etsy API key? (developer.etsy.com)
- Telegram alert chat ID: For revenue alerts (leave blank to disable)
- Revenue alert thresholds:
- Alert if daily sales exceed $[X] (spike alert)
- Alert if no sales for [X] consecutive days (drop alert)
- Weekly revenue goal: $[X]
- Check frequency: Daily at [time] / On demand only
Save to skills/revenue-monitor/config.json.
