# 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."

## Quick Reference

| Phase | Key Activities | Tool Usage | Output |
|-------|---------------|------------|--------|
| **1. Understanding** | Ask questions (one at a time) | AskUserQuestion for choices | Purpose, constraints, criteria |
| **2. Exploration** | Propose 2-3 approaches | AskUserQuestion for approach selection | Architecture options with trade-offs |
| **3. Design Presentation** | Present in 200-300 word sections | Open-ended questions | Complete design with validation |
| **4. Design Documentation** | Write design document | writing-clearly-and-concisely skill | Design doc in docs/plans/ |
| **5. Worktree Setup** | Set up isolated workspace | using-git-worktrees skill | Ready development environment |
| **6. Planning Handoff** | Create implementation plan | writing-plans skill | Detailed task breakdown |

## The Process

Copy this checklist to track progress:

```
Brainstorming Progress:
- [ ] Phase 1: Understanding (purpose, constraints, criteria gathered)
- [ ] Phase 2: Exploration (2-3 approaches proposed and evaluated)
- [ ] Phase 3: Design Presentation (design validated in sections)
- [ ] Phase 4: Design Documentation (design written to docs/plans/)
- [ ] Phase 5: Worktree Setup (if implementing)
- [ ] Phase 6: Planning Handoff (if implementing)
```

### Phase 1: Understanding
- Check current project state in working directory
- Ask ONE question at a time to refine the idea
- **Use AskUserQuestion tool** when you have multiple choice options
- Gather: Purpose, constraints, success criteria

**Example using AskUserQuestion:**
```
Question: "Where should the authentication data be stored?"
Options:
  - "Session storage" (clears on tab close, more secure)
  - "Local storage" (persists across sessions, more convenient)
  - "Cookies" (works with SSR, compatible with older approach)
```

### Phase 2: Exploration
- Propose 2-3 different approaches
- For each: Core architecture, trade-offs, complexity assessment
- **Use AskUserQuestion tool** to present approaches as structured choices
- Ask your human partner which approach resonates

**Example using AskUserQuestion:**
```
Question: "Which architectural approach should we use?"
Options:
  - "Event-driven with message queue" (scalable, complex setup, eventual consistency)
  - "Direct API calls with retry logic" (simple, synchronous, easier to debug)
  - "Hybrid with background jobs" (balanced, moderate complexity, best of both)
```

### 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?" (open-ended)
- Use open-ended questions here to allow freeform feedback

### Phase 4: Design Documentation
After design is validated, write it to a permanent document:
- **File location:** `docs/plans/YYYY-MM-DD-<topic>-design.md` (use actual date and descriptive topic)
- **RECOMMENDED SUB-SKILL:** Use zenpowers:writing-clearly-and-concisely (if available) for documentation quality
- **Content:** Capture the design as discussed and validated in Phase 3, organized into the sections that emerged from the conversation
- Commit the design document to git before proceeding

### Phase 5: Worktree Setup (for implementation)
When design is approved and implementation will follow:
- Announce: "I'm using the using-git-worktrees skill to set up an isolated workspace."
- **REQUIRED SUB-SKILL:** Use zenpowers:using-git-worktrees
- Follow that skill's process for directory selection, safety verification, and setup
- Return here when worktree ready

### Phase 6: Planning Handoff
Ask: "Ready to create the implementation plan?"

When your human partner confirms (any affirmative response):
- Announce: "I'm using the writing-plans skill to create the implementation plan."
- **REQUIRED SUB-SKILL:** Use zenpowers:writing-plans
- Create detailed plan in the worktree

## Question Patterns

### When to Use AskUserQuestion Tool

**Use AskUserQuestion for:**
- Phase 1: Clarifying questions with 2-4 clear options
- Phase 2: Architectural approach selection (2-3 alternatives)
- Any decision with distinct, mutually exclusive choices
- When options have clear trade-offs to explain

**Benefits:**
- Structured presentation of options with descriptions
- Clear trade-off visibility for partner
- Forces explicit choice (prevents vague "maybe both" responses)

### When to Use Open-Ended Questions

**Use open-ended questions for:**
- Phase 3: Design validation ("Does this look right so far?")
- When you need detailed feedback or explanation
- When partner should describe their own requirements
- When structured options would limit creative input

**Example decision flow:**
- "What authentication method?" → Use AskUserQuestion (2-4 options)
- "Does this design handle your use case?" → Open-ended (validation)
