name: brainstorming description: | Refine ideas into detailed designs through Socratic dialogue. Use when: user has rough idea, needs to clarify requirements, explore approaches. Triggers: "brainstorm", "discuss idea", "I'm thinking about", "what if", "help me think through", "explore options", "/brainstorm".

Brainstorming Ideas Into Designs

Overview

Transform rough ideas into fully-formed designs through structured questioning and alternative exploration.

Core principle: Ask questions to understand, explore alternatives, present design incrementally for validation.

Announce at start: "I'm using the Brainstorming skill to refine your idea into a design."

The Process

Phase 1: Understanding

• Check current project state in working directory
• Ask ONE question at a time to refine the idea
• Prefer multiple choice when possible
• Gather: Purpose, constraints, success criteria

Phase 2: Exploration

• Propose 2-3 different approaches
• For each: Core architecture, trade-offs, complexity assessment
• Ask your human partner which approach resonates

Phase 3: Design Presentation

• Present in 200-300 word sections
• Cover: Architecture, components, data flow, error handling, testing
• Ask after each section: "Does this look right so far?"

Phase 4: Planning Handoff

Note the response for later

Ask: "Ready to create the implementation plan?"

When your human partner confirms (any affirmative response):

• Invoke Planning Document to learn about our document structure
• Announce: "I'm using the Writing Plans skill to create the implementation plan."
• Invoke Writing Plans skill
• Create detailed Planning Document and place it under prompts/NNN-concept_plan.md

Phase 5: Worktree Setup (for implementation)

When design is approved and implementation will follow:

Ask: "Should I create the worktree for implementation?"

When your human partner confirms (any affirmative response):

• Announce: "I'm using the Using Git Worktrees skill to set up an isolated workspace."
• Switch to Using Git Worktree skill
• Follow that skill's process for directory selection, safety verification, and setup
• Return here when worktree ready

When to Revisit Earlier Phases

You can and should go backward when:

• Partner reveals new constraint during Phase 2 or 3 → Return to Phase 1 to understand it
• Validation shows fundamental gap in requirements → Return to Phase 1
• Partner questions approach during Phase 3 → Return to Phase 2 to explore alternatives
• Something doesn't make sense → Go back and clarify

Don't force forward linearly when going backward would give better results.

Remember

• One question per message during Phase 1
• Apply YAGNI ruthlessly
• Explore 2-3 alternatives before settling
• Present incrementally, validate as you go
• Go backward when needed - flexibility > rigid progression
• Announce skill usage at start
