What problem does it solve? When a distribution center holds less of a fast-moving SKU than stores and open customer orders are pulling, someone must decide which nodes get the scarce units before the outbound wave loads. A flat fair-share split starves promo stores that would actually sell the stock, while deciding too slowly means the wave cuts without you. This Skill provides the operating method to size the real shortfall, rank nodes, price allocation options, and gate the committing writes. ## Core Features & Use Cases - Shortfall sizing on available-to-deploy: Computes ATD (on-hand minus allocated, held, damaged, and reserved) rather than raw on-hand, with a freshness rule that re-reads ATD at execute time. - Node ranking and tiering: Scores each store and direct order on days-of-supply, promo/planogram priority, lost-sale risk per unit, and SLA exposure, splitting nodes into protect and general tiers. - Three priced allocation splits: Constructs demand-weighted, protect-promo-plus-SLA, and safety-buffer options, each priced in lost-sale dollars for analyst comparison. - Gated cross-system writes: Holds the WMS wave allocation, OMS direct-order allocation, and deployment-plan commit for human approval, with a bounded protect-tier-only fallback when the wave clock runs out. - Use Case: Overnight replenishment shows DC on-hand covering only 78% of network pull for a promo SKU with the wave cutting in 3 hours; the Skill sizes the gap, protects the promo and SLA nodes, prices three splits, and deploys the approved vector before the cut. ## Quick Start Ask the assistant to split scarce DC stock for a SKU where store replenishment plus open orders exceed available-to-deploy before the outbound wave cut-off.
