What does marketing-psychology do?
marketing-psychology is a Claude skill that turns a library of mental models into marketing advice. It first looks for a product marketing context file, such as .agents/product-marketing.md, to tailor its answers. Claude then picks the models that fit your problem, explains the psychology, gives concrete uses and notes how to apply them ethically. The library is grouped into thinking models, buyer psychology, persuasion, pricing psychology, design and delivery, and growth, from anchoring and loss aversion to charm pricing, Hick's Law and flywheels. A table maps problems like price objections or churn to models, and five questions frame each task.
