# Implement Feature

Maximum utilization of parallel subagent execution for feature implementation.

## Quick Start

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

## Phase 1: Discovery & Planning

### 1a. Create Task List

Break into small, deliverable, testable tasks:
- Each task completable in one focused session
- Each task MUST include its tests
- Group by domain (frontend, backend, AI, shared)

### 1b. Research Current Best Practices

```python
# PARALLEL - Web searches (launch all in ONE message)
WebSearch("React 19 best practices 2026")
WebSearch("FastAPI async patterns 2026")
WebSearch("TypeScript 5.x strict mode 2026")
```

### 1c. Context7 Documentation

```python
# PARALLEL - Library docs (launch all in ONE message)
mcp__context7__query-docs(libraryId="/vercel/next.js", query="app router")
mcp__context7__query-docs(libraryId="/tiangolo/fastapi", query="dependencies")
```

## Phase 2: Skills Auto-Loading (CC 2.1.6)

**CC 2.1.6 auto-discovers skills** - no manual loading needed!

Relevant skills activated automatically based on task:
- `api-design-framework` - REST/GraphQL patterns
- `react-server-components-framework` - RSC, Server Actions
- `type-safety-validation` - Zod, tRPC, Prisma
- `unit-testing` / `integration-testing` - Test patterns

## Phase 3: Parallel Architecture Design (5 Agents)

Launch ALL 5 agents in ONE Task message with `run_in_background: true`:

| Agent | Focus |
|-------|-------|
| Plan | Architecture planning, dependency graph |
| backend-system-architect | API, services, database |
| frontend-ui-developer | Components, state, hooks |
| llm-integrator | LLM integration (if needed) |
| ux-researcher | User experience, accessibility |

```python
# PARALLEL - All agents in ONE message
Task(subagent_type="Plan", prompt="...", run_in_background=True)
Task(subagent_type="backend-system-architect", prompt="...", run_in_background=True)
Task(subagent_type="frontend-ui-developer"
