The problem

Manually tracking competitor pricing across multiple tabs is slow and prone to human error. Detecting subtle shifts in promotions or stock status before they impact your sales volume is nearly impossible without automation.

What it does

• Extracts unit price, currency, and tax status from product page DOM or raw text.
• Identifies active discounts, sale prices, and visible promo codes.
• Monitors inventory levels including backorder and low-stock indicators.
• Generates delta reports showing absolute and percentage price changes compared to previous snapshots.
• Provides strategic positioning advice based on observed pricing trends and stock clearing signals.

Why this beats prompting it yourself

Generic prompts often hallucinate price data or fail to distinguish between MSRP and checkout prices. This skill enforces a structured snapshot workflow and mandatory evidence capture to ensure every price delta is grounded in raw data rather than model vibes.

Use cases

• Monitor rival product pages for sudden clearance sales or 10%+ price drops.
• Generate weekly competitive intelligence memos for pricing committees.
• Identify shipping threshold gaps where competitors offer better logistics value.
• Track stock-out events to time aggressive promotional campaigns.

Known limitations

Requires access to product URLs that do not block headless browsing or basic scraping. Snapshot data must be stored locally in JSON lines to enable historical delta comparisons.
