What problem does it solve? Retail metrics like VAT, returns, cost, same-store sales, and snapshot policy are often undefined or ambiguous, leading to untrustworthy dashboards. This Skill routes you through Seshat's public retail KPI knowledge base so every metric has governed meaning, grain, and required fields before any implementation begins. ## Core Features & Use Cases - Governed Metric Definitions: Establish KPI meaning, additivity, grain, and required fields using curated retail knowledge routes. - Ambiguity Escalation: Flags undefined VAT, returns, cost, same-store, or snapshot policy as named-human decisions rather than agent defaults. - Contracts and Handoffs: Produces metric contracts and handoff artifacts ready for downstream warehouse and Power BI implementation. - Use Case: Before building a sales dashboard, use this Skill to define how returns and VAT affect net revenue, lock the grain at store-day level, and record the contract so engineers implement exactly what the business approved. ## Quick Start Use the retail KPI knowledge to define the net sales metric, including VAT and returns policy, grain, and required fields, before implementation.
