Better User Research

The skill helps you pick methods by stage: interviews for an early concept, usability tests once there's a prototype, usage data plus interviews after launch. It isn't built for surveys, analytics, A/B tests, or for synthesizing finished interviews.

Every script outputted will include the exact words a moderator will say, including follow-ups for thin answers. Questions run from broad to specific and ask about what people have actually done, not what they might do. A notes template for the chosen questions will also be included.

New research plans

Plans lean user research. Ask it for a research plan, an interview script, or a usability test, and it writes the file into a research/ folder in your project. If your agent can't write files, it replies with the same document in the chat.

Existing research critique

Share a plan or a list of questions and it reviews them. It flags leading wording, hypothetical questions, feature names that come up too early, and usability tasks that give away the answer. The review ends with an optimized version, ready to use.
