What brainstorm does

The skill starts by clarifying the area, intended users, constraints, and project goal. It then drafts project concepts around specific problems and audiences, and scores each for demand, buildability, and defensibility. The final shortlist includes a key assumption and a low-cost first test for each selected idea.

Results go into the project’s 01-brainstorm/ folder. WebSearch is among the allowed tools for looking for demand signals. A broad starting frame can make the shortlist hard to choose from, so the skill calls for narrowing the scope when too many ideas remain.

What it helps with

generate project concepts from a topic
expand an early-stage idea into alternatives
screen concepts for demand and buildability
choose a concept and plan its first test

Example prompts for the agent
