## Auto Mode

When `--yes` or `-y`: Auto-confirm decisions, use balanced exploration across all perspectives.

# Workflow Brainstorm-With-File Command (/workflow:brainstorm-with-file)

## Overview

Interactive brainstorming workflow with **multi-CLI collaboration** and **documented thought evolution**. Expands initial ideas through questioning, multi-perspective analysis, and iterative refinement.

**Core workflow**: Seed Idea → Expand → Multi-CLI Discuss → Synthesize → Refine → Crystallize

**Key features**:
- **brainstorm.md**: Complete thought evolution timeline
- **Multi-CLI collaboration**: Gemini (creative), Codex (pragmatic), Claude (systematic) perspectives
- **Idea expansion**: Progressive questioning and exploration
- **Diverge-Converge cycles**: Generate options then focus on best paths
- **Synthesis**: Merge multiple perspectives into coherent solutions

## Usage

```bash
/workflow:brainstorm-with-file [FLAGS] <IDEA_OR_TOPIC>

# Flags
-y, --yes              Skip confirmations, use recommended settings
-c, --continue         Continue existing session (auto-detected if exists)
-m, --mode <mode>      Brainstorm mode: creative (divergent) | structured (goal-oriented)

# Arguments
<idea-or-topic>        Initial idea, problem, or topic to brainstorm (required)

# Examples
/workflow:brainstorm-with-file "如何重新设计用户通知系统"
/workflow:brainstorm-with-file --continue "通知系统"              # Continue existing
/workflow:brainstorm-with-file -y -m creative "创新的AI辅助功能"   # Creative auto mode
/workflow:brainstorm-with-file -m structured "优化缓存策略"       # Goal-oriented mode
```

## Execution Process

```
Session Detection:
   ├─ Check if brainstorm session exists for topic
   ├─ EXISTS + brainstorm.md exists → Continue mode
   └─ NOT_FOUND → New session mode

Phase 1: Seed Understanding
   ├─ Parse initial idea/topic
   ├─ Identify brainstorm dimensions (technical, UX, business, etc.)
   ├─ Initial scoping questions (AskUserQuestion)
   ├─ Expand seed into exploration vectors
   └─ Document in brainstorm.md

Phase 2: Divergent Exploration (Multi-CLI Parallel)
   ├─ Gemini CLI: Creative/innovative perspectives
   ├─ Codex CLI: Pragmatic/implementation perspectives
   ├─ Claude CLI: Systematic/architectural perspectives
   └─ Aggregate diverse viewpoints

Phase 3: Interactive Refinement (Multi-Round)
   ├─ Present multi-perspective findings
   ├─ User selects promising directions
   ├─ Deep dive on selected paths
   ├─ Challenge assumptions (devil's advocate)
   ├─ Update brainstorm.md with evolution
   └─ Repeat diverge-converge cycles

Phase 4: Convergence & Crystallization
   ├─ Synthesize best ideas
   ├─ Resolve conflicts between perspectives
   ├─ Formulate actionable conclusions
   ├─ Generate next steps or implementation plan
   └─ Final brainstorm.md update

Output:
   ├─ .workflow/.brainstorm/{slug}-{date}/brainstorm.md (thought evolution)
   ├─ .workflow/.brainstorm/{slug}-{date}/perspectives.json (CLI findings)
   ├─ .workflow/.brainstorm/{slug}-{date}/synthesis.json (final ideas)
   └─ .workflow/.brainstorm/{slug}-{date}/ideas/ (individual idea deep-dives)
```

## Implementation

### Session Setup & Mode Detection

```javascript
const getUtc8ISOString = () => new Date(Date.now() + 8 * 60 * 60 * 1000).toISOString()

const topicSlug = idea_or_topic.toLowerCase().replace(/[^a-z0-9\u4e00-\u9fa5]+/g, '-').substring(0, 40)
const dateStr = getUtc8ISOString().substring(0, 10)

const sessionId = `BS-${topicSlug}-${dateStr}`
const sessionFolder = `.workflow/.brainstorm/${sessionId}`
const brainstormPath = `${sessionFolder}/brainstorm.md`
const perspectivesPath = `${sessionFolder}/perspectives.json`
const synthesisPath = `${sessionFolder}/synthesis.json`
const ideasFolder = `${sessionFolder}/ideas`

// Auto-detect mode
const sessionExists = fs.existsSync(sessionFolder)
const hasBrainstorm = sessionExists && fs.existsSync(brainstormPath)
const forcesContinue = $ARGUMENTS.includes('--continue') || $ARGUMENTS.includes('-c')

const mode = (hasBrainstorm || forcesContinue) ? 'continue' : 'new'

// Brainstorm mode
const brainstormMode = $ARGUMENTS.includes('--mode') 
  ? $ARGUMENTS.match(/--mode\s+(creative|structured)/)?.[1] || 'balanced'
  : 'balanced'

if (!sessionExists) {
  bash(`mkdir -p ${sessionFolder}/ideas`)
}
```

### Phase 1: Seed Understanding

**Step 1.1: Parse Seed & Identify Dimensions**

```javascript
// Brainstorm dimensions for multi-perspective analysis
const BRAINSTORM_DIMENSIONS = {
  technical: ['技术', 'technical', 'implementation', 'code', '实现', 'architecture'],
  ux: ['用户', 'user', 'experience', 'UX', 'UI', '体验', 'interaction'],
  business: ['业务', 'business', 'value', 'ROI', '价值', 'market'],
  innovation: ['创新', 'innovation', 'novel', 'creative', '新颖'],
  feasibility: ['可行', 'feasible', 'practical', 'realistic', '实际'],
  scalability: ['扩展', 'scale', 'growth', 'performance', '性能'],
  security: ['安全', 'security', 'risk', 'protection', '风险']
}

function identifyDimensions(topic) {
  const text = topic.toLowerCase()
  const matched = []
  
  for (const [dimension, keywords] of Object.entries(BRAINSTORM_DIMENSIONS)) {
    if (keywords.some(k => text.includes(k))) {
      matched.push(dimension)
    }
  }
  
  // Default dimensions based on mode
  if (matched.length === 0) {
    return brainstormMode === 'creative' 
      ? ['innovation', 'ux', 'technical']
      : ['technical', 'feasibility', 'business']
  }
  
  return matched
}

const dimensions = identifyDimensions(idea_or_topic)
```

**Step 1.2: Initial Scoping Questions**

```javascript
const autoYes = $ARGUMENTS.includes('--yes') || $ARGUMENTS.includes('-y')

if (mode === 'new' && !autoYes) {
  // Expand the seed with targeted questions
  AskUserQuestion({
    questions: [
      {
        question: `头脑风暴主题: "${idea_or_topic}"\n\n您希望探索哪些方向?`,
        header: "方向",
        multiSelect: true,
        options: [
          { label: "技术方案", description: "探索技术实现可能性" },
          { label: "用户体验", description: "从用户角度出发" },
          { label: "创新突破", description: "寻找非常规解决方案" },
          { label: "可行性评估", description: "评估实际落地可能" }
        ]
      },
      {
        question: "头脑风暴深度?",
        header: "深度",
        multiSelect: false,
        options: [
          { label: "快速发散", description: "广度优先，快速生成多个想法 (15-20分钟)" },
          { label: "平衡探索", description: "深度和广度平衡 (30-60分钟)" },
          { label: "深度挖掘", description: "深入探索少数核心想法 (1-2小时)" }
        ]
      },
      {
        question: "是否有任何约束或必须考虑的因素?",
        header: "约束",
        multiSelect: true,
        options: [
          { label: "现有架构", description: "需要与现有系统兼容" },
          { label: "时间限制", description: "有实施时间约束" },
          { label: "资源限制", description: "开发资源有限" },
          { label: "无约束", description: "完全开放探索" }
        ]
      }
    ]
  })
}
```

**Step 1.3: Expand Seed into Exploration Vectors**

```javascript
// Generate exploration vectors from seed idea
const expansionPrompt = `
Given the initial idea: "${idea_or_topic}"
User focus areas: ${userFocusAreas.join(', ')}
Constraints: ${constraints.join(', ')}

Generate 5-7 exploration vectors (questions/directions) to expand this idea:

1. Core question: What is the fundamental problem/opportunity?
2. User perspective: Who benefits and how?
3. Technical angle: What enables this technically?
4. Alternative approaches: What other ways could this be solved?
5. Challenges: What could go wrong or block success?
6. Innovation angle: What would make this 10x better?
7. Integration: How does this fit with existing systems/processes?

Output as structured exploration vectors for multi-perspective analysis.
`

// Use quick Gemini call to expand seed
const expansionResult = await Bash({
  command: `ccw cli -p "${expansionPrompt}" --tool gemini --mode analysis --model gemini-2.5-flash`,
  run_in_background: false
})

const explorationVectors = parseExpansionResult(expansionResult)
```

**Step 1.4: Create brainstorm.md**

## Multi-CLI Collaboration Strategy

### Perspective Roles

| CLI | Role | Focus | Best For |
|-----|------|-------|----------|
| Gemini | Creative | Innovation, cross-domain | Generating novel ideas |
| Codex | Pragmatic | Implementation, feasibility | Reality-checking ideas |
| Claude | Systematic | Architecture, structure | Organizing solutions |

### Collaboration Patterns

1. **Parallel Divergence**: All CLIs explore simultaneously from different angles
2. **Sequential Deep-Dive**: One CLI expands, others critique/refine
3. **Debate Mode**: CLIs argue for/against specific approaches
4. **Synthesis Mode**: Combine insights from all perspectives

### When to Use Each Pattern

- **New topic**: Parallel Divergence → get diverse initial ideas
- **Promising idea**: Sequential Deep-Dive → thorough exploration
- **Controversial approach**: Debate Mode → uncover hidden issues
- **Ready to decide**: Synthesis Mode → create actionable conclusion

## Error Handling

| Situation | Action |
|-----------|--------|
| CLI timeout | Retry with shorter prompt, or continue without that perspective |
| No good ideas | Reframe the problem, adjust constraints, try different angles |
| User disengaged | Summarize progress, offer break point with resume option |
| Perspectives conflict | Present as tradeoff, let user decide direction |
| Max rounds reached | Force synthesis, highlight unresolved questions |
| All ideas fail challenge | Return to divergent phase with new constraints |

## Usage Recommendations

Use `/workflow:brainstorm-with-file` when:
- Starting a new feature/product without clear direction
- Facing a complex problem with multiple possible solutions
- Need to explore alternatives before committing
- Want documented thinking process for team review
- Combining multiple stakeholder perspectives

Use `/workflow:analyze-with-file` when:
- Investigating existing code/system
- Need factual analysis over ideation
- Debugging or troubleshooting
- Understanding current state

Use `/workflow:plan` when:
- Direction is already clear
- Ready to move from ideas to execution
- Need implementation breakdown
