What problem does it solve? Marketing campaign workflows with multiple AI agents break down when the strategic brief is ambiguous prose. This Skill defines a canonical, versioned, JSON-parseable contract (the Golden Briefing) that the Strategist agent produces and downstream agents consume as ground truth, eliminating ambiguity and lost context between agents. ## Core Features & Use Cases - Canonical Schema Definition: Specifies every field of the Golden Briefing, from strategic focus and demand currents to territory hierarchy, channel roles, and prior-period performance data. - Traceability and Provenance: Requires every informative claim to carry a procedencia block (level, source, validation status) and evidence references to source documents. - Validation Checklist: Ships 14+ validation rules covering rubric evaluation, performance metrics, coverage of weekly reports, and approval gating before publication. - Use Case: A Strategist agent reads a client's monthly commercial plan (PPTX/XLSX), produces one Golden Briefing per stream (growth-value and dispositivos), and downstream copywriting and media agents consume it without re-interpreting the source documents. ## Quick Start Use the Golden Briefing Schema to validate this draft briefing JSON for the growth-value stream and list every rule it violates.
