# Ad variant factory Take one approved concept and explode it into 10-30 shippable ad variants for A/B testing on Meta, Google, TikTok, and Pinterest. Built for speed (parallel batch) and for direct upload to ad accounts (deterministic naming). ## When to Use - User has a hero / concept and needs many variants across headline × visual × CTA × background for A/B tests. - "Fan out 30 variants of this ad for Meta" / "generate a test matrix" / "multiply this creative". - Prepping a new ad-set launch — needs 9:16, 1:1, 16:9 with 3-5 visual variants each. - Do NOT use for a single hero (use `gen-ai generate`) or for cross-channel creative (use `marketer-campaign-kit`). This skill is for depth on one concept, not breadth across channels. ## Prerequisites Ask up front if the brief doesn't cover it (combine into one message): 1. **Hero asset** — path or URL to the approved concept image. 2. **Axes to vary** — visual direction (1-5), background/scene (1-5), focal composition (close-up vs wide), optional: color treatment. 3. **Platforms / aspect ratios** — Meta needs 9:16 + 1:1, TikTok is 9:16, Display wants 16:9. Confirm which. 4. **Variant count** — how many total? 10-15 is typical for a first test, 30+ for broad exploration. 5. **Naming convention** — what does the ad platform require (e.g. `{campaign}_{axis}_{variant}_{size}.webp`)? 6. **Brand guardrails** — colors (hex), forbidden elements, existing brand.md? If the user just says "a lot", default to 5 visuals × 3 ratios = 1
