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:

// 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:

{
  "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",
        "plan": "Step-by-step implementation..."
      }
    },
    {
      "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...",

Next Steps to Use

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

# 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)

# 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:

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"]
  }'

---

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:

// 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

---

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
