Behavioral Design Claude Skill — Design skill for Claude Code

Behavioral Design Guide - Claude Skill

You know the behavior you want to change. You've studied multiple frameworks, maybe already tried them on your work, personal projects or life. But when you sit down to actually try to follow the behavioral design process — define the behavior precisely, find the real barriers, pick the right intervention, et cetera — the process suddenly feels...scattered. Which framework do I use here? Am I missing something in my analysis? Is this rigorous and science-based enough?

Sounds familiar?

This skill is a thinking partner for that whole process. It walks you through a full behavioral design cycle, recommends frameworks at each step with reasoning, and supports your decisions. It's not a replacement for expertise — it's a scaffold that helps you apply what you know more systematically.

Built for UX researchers, product managers, and behavioral designers who need key BeSci frameworks all in one place.

What It Does

The skill walks you through 8 stages of a behavioral design cycle. At each stage, it asks you questions, recommends a framework with reasoning, and produces a structured output before moving on.

Stage	What happens	What you get
DEFINE	Nail down exactly what behavior you're changing, for whom, and when. The skill names 2-3 definition tools that fit your case, gives trade-offs for each, recommends one with reasoning, and lets you confirm or pick differently.	A precise, measurable behavior statement that passes the "can you physically mime this?" test.
EVIDENCE CHECK	Establish what you know and don't know about this behavior — before mapping or diagnosing. The skill asks what data you have (analytics, research, prior tests, domain knowledge), names 1-3 useful gaps, and gives a baseline of what published evidence says about this category of behavior.	A short summary you can refer back to: what data exists, what gaps matter and how to handle them, what's known about this be
