What this skill does

Refines raw ideas into sharp, actionable concepts through structured divergent and convergent thinking. Use when an idea is still vague, when you need to stress-test assumptions before committing to a plan, or when you want to expand options before converging on one. Triggers on "ideate", "refine this idea", or "stress-test my plan". This skill is primarily an interactive dialogue. Invoke it with an idea, and the agent will guide you through the process.
