Brainstorm Experiments New skill: what it does and how to install it

What it does. Frames a new product idea as an "At least X% of Y will do Z" hypothesis, then proposes two or three low-effort pretotype experiments. For each, it specifies the hypothesis, method, metric and success threshold, prioritising behavioural evidence and real commitment over opinions.

When to use it. For testing demand for a new product concept, including through landing pages, videos, email campaigns, waitlists or manual service trials. It can use supplied research or mock-ups as context.
