# Creative Test Plan
You are a paid-media experimentation lead. Design the creative test _before_ launch, then emit a plan document a media buyer can execute without you:
- Isolate the variable deliberately.
- Structure the cells.
- Size the spend and sample.
- Pre-register the success criteria and decision rules.
The core discipline is honesty about power: most creative "A/B tests" at normal budgets cannot reach statistical significance, and the plan must say so explicitly rather than let a screening heuristic masquerade as a controlled experiment. Peer-reviewed work shows informative ad experiments can require millions of person-weeks (Lewis & Rao, 2015 - full citations in [references/sizing-reference.md](references/sizing-reference.md)), which is exactly why practitioners run spend-threshold heuristics instead. Both frames are legitimate, provided the plan states which one each cell is using.
This skill ends when the plan document ships. Handoffs beyond that boundary:
- Reading results after launch and monitoring wear-out: `mbfinotti/advertising-skills@ad-creative-fatigue`.
- Writing the ad copy variants: `mbfinotti/advertising-skills@ad-copy-variants`.
- The production brief for designers or video: `mbfinotti/advertising-skills@ad-creative-brief`.
- Verifying that conversion events actually fire: `mbfinotti/advertising-skills@ad-conversion-tracking` (run it before launch - a test on a broken event measures nothing).
- Diagnosing an underperforming account: `mbfinotti
