Brainstorming Skill — Development skill for Claude Code

Brainstorming Skill

A Claude Code skill for turning ideas into fully formed designs and specs through natural collaborative dialogue.

**Use before any creative work** — creating features, building components, adding functionality, or modifying behavior. This skill explores user intent, requirements, and design before implementation.

What it does

• Walks from raw idea to approved design spec via one-question-at-a-time dialogue
• Presents 2-3 approaches with tradeoffs before settling on one
• Writes a design doc (docs/superpowers/specs/YYYY-MM-DD--design.md)
• Self-reviews the spec for placeholders, contradictions, ambiguity, and scope
• Hands off to writing-plans for implementation planning

Install

Clone into your Claude Code skills directory:

git clone https://github.com/qwwiwi/brainstorming-skill ~/.claude/skills/brainstorming

Usage

Claude Code auto-invokes this skill when the user describes creative work. You can also invoke it manually:

Use the brainstorming skill to help me design a new feature for X.

Visual Companion (optional)

For visual questions (mockups, layouts, diagrams), the skill offers a local browser-based companion. Run:

bash scripts/start-server.sh

It watches a directory for HTML files and serves the newest one. Claude writes mockups, you click to pick options, selections are logged back.
