What problem does it solve? Paid-media teams often ship ad creative built on unverified claims, cosmetic variants, or gut-feel refreshes, wasting budget and risking policy violations. This Skill grounds every creative concept in named evidence and structures each test around a single strategic variable with clear success and failure criteria. ## Core Features & Use Cases - Evidence-grounded concept cards: Produces three distinct ready_for_review concept cards, each with a hypothesis (audience × motivation × angle × format × one variable), a claim ledger flagging unsupported claims as needs_substantiation, and a visual/production brief. - Structured test design: Defines success metrics, guardrails, attribution windows, observation windows, and failure conditions per concept, and diagnoses creative fatigue using complete-window frequency, link CTR, CPM, and delivery context before recommending a refresh. - Platform routing and publication boundary: Routes execution to platform-specific skills (Google Ads copy/assets, Meta, X, LinkedIn) and validates current platform specs and policies before publishing, outputting operator-ready briefs where no verified mutation surface exists. - Use Case: A growth marketer asks for a Meta creative refresh for a SaaS product; the Skill returns three concept cards tied to verified customer research and approved landing-page claims, each testing one variable with defined guardrails. ## Quick Start Use the paid-ads-creative skill to create three evidence-backed ad concept cards and a test plan for our Meta campaign targeting small business owners.
