# Feature Development Workflow

A comprehensive, structured workflow for feature development with specialized agents for codebase exploration, architecture design, and quality review.

## Quick Start

Launch the guided feature development workflow:

```bash
/feature-dev Add user authentication with OAuth
```

Or interactively:

```bash
/feature-dev
```

The workflow will guide you through 7 distinct phases automatically.

## Overview

Building features requires more than just writing code. This skill provides a systematic approach that:
- **Understands the codebase** before making changes
- **Asks clarifying questions** to resolve ambiguities
- **Designs thoughtfully** with multiple architecture options
- **Reviews for quality** after implementation

## The 7-Phase Workflow

### Phase 1: Discovery
**Goal**: Understand what needs to be built

- Clarifies unclear feature requests
- Identifies problem, constraints, and requirements
- Summarizes understanding and confirms with user

**Example**:
```
User: /feature-dev Add caching
Agent: Let me understand what you need...
       - What should be cached? (API responses, computed values, etc.)
       - What are your performance requirements?
       - Do you have a preferred caching solution?
```

### Phase 2: Codebase Exploration
**Goal**: Understand relevant existing code and patterns

- Launches 2-3 `code-explorer` agents in parallel
- Explores similar features, architecture, UI patterns
- Reads all identified files for deep understanding
- Presents comprehensive summary of findings

**Agents launched**:
- "Find features similar to [feature] and trace implementation"
- "Map the architecture and abstractions for [area]"
- "Analyze current implementation of [related feature]"

**Example output**:
```
Found similar features:
- User authentication (src/auth/): Uses JWT tokens, middleware pattern
- Session management (src/session/): Redis-backed, 24hr expiry

Key files:
- src/auth/AuthService.ts:45 - Core authentication logic
