This is for when you need to apply behavioral psychology to marketing without drowning in theory. It uses a scoring system called PLFS that rates mental models on leverage, fit, implementation ease, speed to signal, and ethical safety. You get a maximum of five models per situation, each mapped to a specific behavior and surface like a pricing page or CTA. The skill includes journey-based guidance so you're not applying awareness-stage tactics to retention problems. What I like here is the hard ethical guardrails and the mandate to score everything numerically. It's opinionated about not being manipulative, which frankly makes it more useful than a generic bias encyclopedia.
