What it does
Once installed, the agent answers marketing questions using a library of psychology and decision-making ideas, such as anchoring, social proof, scarcity, loss aversion, framing, and first-principles thinking. For each relevant idea it explains the underlying psychology, gives a concrete marketing application, and suggests how to use it ethically. If a product marketing context file exists, it reads that first to tailor the advice.
Great for
- Marketers who want to understand why customers hesitate or buy
- Founders and copywriters brainstorming persuasive angles for a campaign
- Students learning consumer behavior and behavioral science in a practical setting
Skip it if
- Replacing testing: the ideas are heuristics and do not guarantee results in a specific audience, so conversion changes still need experiments (the skill itself says to check the obvious first)
- Manipulative dark-pattern tactics: the skill frames its advice around ethical use, but a user could still ask it to exploit biases, so review outputs before publishing
Try asking
- “Which psychological principles could help explain why my free trial signups stall at the pricing page?”
- “Give me three ethical ways to apply social proof on our landing page for a B2B software product.”
- “Explain loss aversion and show how to frame our onboarding email around it.”
- “Use first-principles thinking to challenge whether we should invest in content marketing at all.”
