What problem does it solve? Writers covering out-of-home advertising often produce campaign analysis padded with generic marketing theory, invented visual details, or unattributed brand claims. This Skill produces a rigorous, evidence-labeled analysis block where every conclusion is marked as observed, sourced, inferred, or unknown, so downstream articles never rest on fabricated facts. ## Core Features & Use Cases - Evidence-labeled analysis: Every conclusion carries exactly one label ([Observed], [Sourced], [Inference], or [Unknown]) with sources named and inference bases stated. - Relevance-based lens selection: Selects three to five analytical lenses from a 23-point framework covering strategy, creative, media, market context, and verdict, instead of mechanically completing a checklist. - Strict no-invention guardrails: Makes no visual claims without a supplied image, never estimates reach or spend, and marks missing facts as [Unknown] with the evidence that would settle them. - Use Case: A writer receives a press release and one photo of a Dubai billboard campaign. The Skill extracts the campaign fact sheet, analyzes the brand codes, media format, and funnel role in depth, and hands the labeled block to the copywriting skill for drafting. ## Quick Start Analyze the strategy behind this out-of-home campaign and label every conclusion with its evidence level.
