## How It Works

### The Pipeline You Requested

```
┌─────────────────────────────────────────────────────────┐
│  User Request: "Add feature X"                          │
└─────────────────────────────────────────────────────────┘
                         ↓
┌─────────────────────────────────────────────────────────┐
│  Step 1: REVIEW (Zen codereview)                        │
│  → Analyze existing code                                │
│  → Identify patterns and constraints                    │

└─────────────────────────────────────────────────────────┘
                         ↓
┌─────────────────────────────────────────────────────────┐
│  Step 2: BRAINSTORM (Zen chat with GPT-5.1)            │
│  → Generate 3-5 solution approaches                     │
│  → List pros/cons for each                              │

└─────────────────────────────────────────────────────────┘
                         ↓
┌─────────────────────────────────────────────────────────┐
│  Step 3: CONSENSUS (Zen consensus)                      │
│  → GPT-5.1 evaluates (FOR stance)                       │
│  → Gemini-2.5-Pro evaluates (AGAINST stance)            │
│  → Claude Sonnet 4.5 evaluates (NEUTRAL stance)         │
│  → Synthesis of all perspectives                        │
└─────────────────────────────────────────────────────────┘
                         ↓
┌─────────────────────────────────────────────────────────┐
│  Step 4: DECIDE (Zen chat with Gemini 3 Pro)           │
│  → Best model makes final decision                      │
│  → Creates detailed implementation plan                 │
│  → Step-by-step instructions                            │
└─────────────────────────────────────────────────────────┘
                         ↓
┌─────────────────────────────────────────────────────────┐
│  Step 5: IMPLEMENT (Ready for execution)                │
│  → Returns implementation plan                          │
│  → Claude Code can execute using Write/Edit tools      │
└─────────────────────────────────────────────────────────┘
```

### Context Preservation

Each step uses Zen's `continuation_id` to maintain full context:
- Step 1 creates continuation_id
- Steps 2-4 receive it and see all previous context
- No need to re-send data between steps

---

## Usage Example

### From Claude Code:

```javascript
// Use the smart implementation workflow
Use tool: dss_smart_implement

Parameters:
{
  "task_description": "Add dark mode toggle to dashboard with persistence",
  "context_files": [
    "/home/overbits/dss/admin-ui/index.html",
    "/home/overbits/dss/admin-ui/js/core/app.js"
  ],
  "requirements": "Must persist user preference in localStorage and sync with system theme"
}
```

### Response:

```json
{
  "workflow_id": "abc-123-def-456",
  "status": "completed",
  "steps": [
    {
      "step": "review",
      "status": "completed",
      "result": {
        "findings": "Current code uses inline styles, no theme system present...",
        "issues_found": []
      }
    },
    {
      "step": "brainstorm",
      "status": "completed",
      "result": {
        "approaches": [
          "1. CSS custom properties approach...",
          "2. Class-based theme switching...",
          "3. CSS-in-JS with theme provider..."
        ]
      }
    },
    {
      "step": "consensus",
      "status": "completed",
      "result": {
        "synthesis": "All models agreed CSS custom properties is best approach..."
      }
    },
    {
      "step": "decide",
      "status": "completed",
      "result": {
        "decision": "Implement using CSS custom properties with localStorage persistence",

      }
    },
    {
      "step": "implement",
      "status": "ready",
      "plan": "1. Create theme.css with :root variables...",
      "note": "Implementation plan ready. Execute using Write/Edit tools."
    }
  ],
  "final_implementation": "Detailed step-by-step implementation plan...",
  "decision_rationale": "Consensus analysis and multi-model reasoning..."

**Use for**:
- Complex features requiring architectural decisions
- Security-sensitive implementations
- Performance-critical code
- Major refactoring

**Time**: 3-5 minutes

---

### `dss_review_brainstorm_decide` (Fast Track) ⚡
**Use for**:
- Bug fixes
- Simple features
- Quick decisions
- Time-sensitive tasks

**Time**: 1-2 minutes

---

### `dss_consensus_implement` (Green-field) 🆕

**Time**: 2-3 minutes

---

## Models Used

| Step | Model | Why |
|------|-------|-----|
| Review | gpt-5.1 | Excellent code analysis |
| Brainstorm | gpt-5.1 | Creative thinking |
| Consensus (For) | gpt-5.1 | Optimistic view |
| Consensus (Against) | gemini-2.5-pro | Critical analysis |
| Consensus (Neutral) | claude-sonnet-4-5 | Balanced perspective |
| Final Decision | **gemini-3-pro-preview** | **Best overall reasoning** |

## Next Steps to Use

### Option 1: Test Without MCP Server Restart (Python Direct)

```bash
# Test the workflow tools directly
cd /home/overbits/dss
python3 << 'EOF'
from tools.dss_mcp.tools.workflow_tools import WORKFLOW_TOOLS

for tool in WORKFLOW_TOOLS:
    print(f"✓ {tool.name}")
    print(f"  {tool.description.strip()[:80]}...")
    print()
EOF
```

### Option 2: Restart MCP Server (Make Available in Claude Code)

```bash
# If MCP server is running, restart it
# (This will make tools available in Claude Code)

# Check if running
ps aux | grep "dss.*mcp"

# Kill if running
pkill -f "tools.dss_mcp.server"

# Start new instance
cd /home/overbits/dss
python3 -m tools.dss_mcp.server
```

### Option 3: Use Via API (After Implementation)

Once API endpoints are implemented:
```bash
curl -X POST http://localhost:3456/api/workflow/smart-implement \
  -H "Content-Type: application/json" \
  -d '{
    "task_description": "Add feature X",
    "context_files": ["/path/to/file.js"]
  }'
```

2. `.dss/ZEN_WORKFLOW_ORCHESTRATION.md` - 15K, documentation
3. `.dss/ZEN_WORKFLOW_IMPLEMENTATION_SUMMARY.md` - This file

### Modified Files
1. `tools/dss_mcp/server.py`:
   - Added WORKFLOW_TOOLS import
   - Extended tools list
   - Added workflow routing in call_tool handler

---

## Status

### ✅ Completed
- Tool implementation (workflow_tools.py)
- MCP server integration
- Documentation
- Project memory updated

### ⏳ Pending (To Make Fully Functional)
- [ ] Actually call Zen MCP tools (currently returns structure showing how)
- [ ] Test with real Zen tool calls
- [ ] Restart MCP server to load new tools
- [ ] Test from Claude Code
- [ ] Add API endpoints (optional, for non-MCP access)

### 🔧 Current State

**Code is ready** but uses placeholder Zen calls. To make fully functional:

1. **Replace placeholders** in `workflow_tools.py`:
   - `_call_zen_chat()` → Actually call `mcp__zen__chat`
   - `_call_zen_codereview()` → Actually call `mcp__zen__codereview`
   - `_call_zen_consensus()` → Actually call `mcp__zen__consensus`

2. **Restart MCP server** to load tools

3. **Test** with real workflow

---

## Example End-to-End Test

Once fully functional, test like this:

```javascript
// 1. Start workflow
Use tool: dss_smart_implement
{
  "task_description": "Add export to CSV feature",
  "context_files": ["/path/to/file.js"]
}

// 2. Wait for completion (3-5 min)
// Returns workflow_id and implementation plan

// 3. Check status
Use tool: dss_workflow_status
{ "workflow_id": "abc-123" }

// 4. Execute plan
// Use Write/Edit tools to implement the plan
```

---

## Architecture Fit

This fits into the broader DSS MCP architecture:

```
DSS MCP Tools
├── Project Tools (existing)
│   ├── dss_get_project_summary
│   ├── dss_list_components
│   └── ...
│
├── Workflow Tools (NEW!) ⭐
│   ├── dss_smart_implement
│   ├── dss_review_brainstorm_decide
│   ├── dss_consensus_implement
│   └── dss_workflow_status
│
└── Debug Tools (designed, not yet implemented)
    ├── dss_get_browser_diagnostic
    ├── dss_get_browser_errors
    └── ...
```

---

## What Makes This Special

1. **Automated Decision Pipeline**: No manual back-and-forth
2. **Multi-Model Validation**: 3 different AI perspectives
3. **Best Model Decides**: Gemini 3 Pro for final call
4. **Context Preserved**: Continuation ID maintains full history
5. **Audit Trail**: Every step logged
6. **Flexible**: 3 workflow types for different use cases

---

**Implementation Status**: ✅ Code Complete, Pending Integration Testing
**Next Action**: Test with real Zen tool calls or restart MCP server
