Brainstorm

This is the skill you want before jumping into code when the problem is fuzzy or the stakes are high. It walks you through gathering context, asking clarifying questions one at a time, exploring 2-5 approaches with tradeoffs, then building out a design incrementally in phases so you're not drowning in a wall of text. The whole thing runs interactively in one session and ends with a choice: write a plan, generate design artifacts in a timestamped docs folder, implement directly, or just stop. The phased presentation is smart. Most brainstorming tools either give you nothing or dump everything at once. This one lets you steer as you go.
