What problem does it solve? Campaign planning agents produce strategy artifacts that must be consistent, versioned, and traceable to an approved brief. This Skill defines the canonical schemas for the Channel Strategy (media_strategy.json) and Creative Strategy (campaign_creative-strategy.json) outputs, including validation rules, provenance tracking, and associated visual outputs (DOCX narratives and HTML one-pagers). ## Core Features & Use Cases - Canonical artifact schemas: Defines the full YAML/JSON structure for media strategies (territory prioritization, channel detail, calendar tables, handoff block) and creative strategies (strategic framework, per-stream campaigns, copy prototypes, communication scoring). - Validation and traceability rules: Enforces 36+ validation checks covering brief references, provenance blocks (nivel/fuente/validacion), principle checks, and anti-pattern detection such as multi-message campaigns or unjustified copy variants. - Visual output specification: Standardizes versioned HTML one-pagers (Gantt calendars, channel matrices, load heatmaps) and DOCX narratives using Movistar brand palette per sub-stream (Growth, Value, Dispositivos). - Use Case: A Planner agent finishes a media strategy for a June campaign; this Skill validates that every channel references a playbook, every claim carries a provenance block, and the handoff to the Creative Copywriter is complete before approval. ## Quick Start Validate my media_strategy.json output against the campaign output format schema and list any missing provenance blocks or failed principle checks.
