des-gold-layer-design

What problem does it solve?

It prevents AI agents from moving too fast into implementation by forcing a structured, evidence-backed design of the Gold Layer so downstream consumers get correct, traceable, metric-consistent, contract-aware datasets.

Core Features & Use Cases

• Gold Layer Specification for Phase 11: Define what Gold datasets should exist, why they exist, and how they answer approved business questions and KPIs.
• Mapping and traceability: Create explicit mappings from Business Questions, Requirements/KPIs, Data Product outputs, and trusted Silver datasets to Gold outputs.
• Consumer-ready design constraints: Establish grain, aggregation, slicing, history/SCD behavior, freshness/SLA, security/access handling, lineage expectations, and performance/cost considerations.
• Phase-Orchestrated support & evidence: Produce the Phase 11 support plan, evidence pack, revision notes, Done Gate result, and a safe handoff to Phase 12 without writing transformation code.

Quick Start

Use the des-gold-layer-design skill to generate the file _des-output/planning-artifacts/11-gold-layer-specification.md based on your Phase 01–10 planning artifacts and Phase 10 to 11 handoff, then stop at HALT when any Gold boundary, grain, metric alignment, serving, contract expectation, or lineage decision cannot be safely inferred.
