knownasnaffy Bundle Promo Stock 3During peak sales (Black Friday, Cyber Monday, Singles' Day, flash sales), align hot-SKU remaining inventory with live ad spend—surface sell-through risk, auto-style Pre-order messaging when stock crosses a threshold, and produce supplier restock chase communications. Use this skill whenever the user mentions inventory under ~20% while ads still run, the last 24 hours before a major promo, oversell risk, cutting Meta/Google/TikTok when stock is thin, switching PDP to pre-order, or supplier expedite emails—even if they only say "we might stock out during the sale" or "ads are still on but warehouse is low." Also trigger on safety stock breaches, SKU-level pacing, and multi-channel inventory sync. Do NOT use for annual financial inventory audits with no live promo or ads context, pure demand forecasting with no immediate copy or comms need, or legal product compliance for pre-orders in regulated categories without the user asking for operational templates.
