Workspace Structure

Creates ~/asin-tracker/ containing:

• watchlist.md — all tracked ASINs with settings
• snapshots/ — date-stamped metric files per ASIN
• alerts/ — triggered alert log
• exports/ — generated export files
• reports/ — monitoring summary reports

Analysis Rules

1. Require at least 2 data points before declaring a trend
2. Distinguish between organic and promotional BSR movements
3. Flag BSR improvements during Prime Day, Black Friday, holiday seasons as potentially seasonal
4. Never declare a price drop permanent until it holds for 7+ days
5. Cross-reference review velocity with known promotion dates before flagging manipulation
6. Always timestamp every data point — tracking is only useful with temporal context

Output Format

Every report outputs:

1. Current Snapshot Table — all tracked ASINs with latest metrics
2. Changes Since Last Check — delta table showing what moved and by how much
3. Active Alerts — list of triggered conditions with severity (High/Medium/Low)
4. Trend Summary — 30-day direction for each key metric
5. Recommended Actions — prioritized response list based on detected changes
