# Implement Feature

Maximum utilization of parallel subagent execution for feature implementation with built-in scope control and reflection.

## Quick Start

```bash
/implement user authentication
/implement real-time notifications
/implement dashboard analytics
```

## STEP 0: Verify User Intent with AskUserQuestion

**BEFORE creating tasks or doing ANY work**, ask the user to clarify scope:

```python
AskUserQuestion(
  questions=[
    {
      "question": "What scope for this implementation?",
      "header": "Scope",
      "options": [
        {"label": "Full-stack (Recommended)", "description": "Backend + frontend + tests + docs"},
        {"label": "Backend only", "description": "API + database + backend tests"},
        {"label": "Frontend only", "description": "UI components + state + frontend tests"},
        {"label": "Quick prototype", "description": "Minimal working version, skip tests"}
      ],
      "multiSelect": false
    },
    {
      "question": "Any constraints I should know about?",
      "header": "Constraints",
      "options": [
        {"label": "None (Recommended)", "description": "Use best practices and modern patterns"},
        {"label": "Match existing patterns", "description": "Follow existing codebase conventions exactly"},
        {"label": "Minimal dependencies", "description": "Avoid adding new packages"},
        {"label": "Specific tech stack", "description": "I'll specify the technologies to use"}
      ],
      "multiSelect": false
    }
  ]
)
```

**Based on user's answers, adjust the workflow:**
- **Full-stack**: All 10 phases, all parallel agents
- **Backend only**: Skip frontend agents (phases 5b, 6b)
- **Frontend only**: Skip backend agents (phases 5a, 6a)
- **Quick prototype**: Skip phases 7-10 (scope check, verification, docs, reflection)

## CRITICAL: Task Management is MANDATORY (CC 2.1.16)

**BEFORE doing ANYTHING else, create tasks to track progress:**

```python
# 1. Create main implementation task IMMED
