### 1. Create Your First Project

```bash
# Initialize new SpecPulse project
specpulse init my-project --ai claude

# Or add to existing project
cd existing-project
specpulse init --here --ai claude
```

└── .specpulse/      # Configuration
```

### 2. Start a Feature

```bash
# Initialize feature with structure
specpulse feature init user-authentication

# This creates:

# - Git branch: 001-user-authentication
# - Updates project context
```

### 3. Create Specification

```bash
# Create specification
specpulse spec create "OAuth2 authentication with JWT tokens"

```bash
specpulse feature init <name>          # Start new feature
specpulse feature continue <id>        # Switch to existing feature
specpulse feature list                 # List all features
```

### Specification Management

```bash
specpulse spec create "<description>"  # Create specification
specpulse spec validate [id]           # Validate spec(s)
specpulse spec list                    # List all specs
specpulse spec progress <id>           # Show completion progress
```

### Planning & Tasks

```bash
specpulse plan create "<description>"  # Create implementation plan
specpulse plan validate [id]           # Validate plan(s)
specpulse task breakdown <plan-id>     # Break into tasks
specpulse task list                    # List all tasks
```

### Template Management

```bash
specpulse template list                # List available templates
specpulse template validate            # Validate templates
specpulse template preview <name>      # Preview template rendering
```

### Utilities

```bash
specpulse decompose <spec-id>          # Decompose into components
specpulse sync                         # Synchronize project state
specpulse checkpoint create <id> "desc" # Create checkpoint
specpulse checkpoint restore <id> <name> # Restore checkpoint
```

## 🤖 AI Integration

SpecPulse works seamlessly with AI assistants while maintaining **privacy-first design** (no external API calls).

### Supported AI Platforms

- **Claude Code** - Custom slash commands
- **Gemini CLI** - Custom commands

### Using with Claude Code

```bash
# In Claude Code terminal:
/sp-pulse user-authentication          # Initialize feature
/sp-spec OAuth2 with JWT               # Create specification
/sp-plan generate                      # Generate implementation plan
/sp-task breakdown                     # Break into tasks
```

### How It Works

1. **Specification First**: Create validated specs before coding
2. **AI Expansion**: LLM expands templates with detailed content
3. **Validation**: Automatic checks ensure quality
4. **Tracking**: Progress monitoring throughout development
5. **Privacy**: All processing happens locally
