## Input Processing

### Argument Handling
```bash
validate_and_process_arguments() {
    if [ -n "$ARGUMENTS" ]; then
        # Check if argument is a file path
        if [ -f "$ARGUMENTS" ]; then
            echo "📄 Loading requirements from file: $ARGUMENTS"
            REQUIREMENTS=$(cat "$ARGUMENTS")
            INPUT_TYPE="file"
        elif [ -d "$ARGUMENTS" ]; then
            echo "📁 Analyzing directory scope: $ARGUMENTS"
            SCOPE_PATH="$ARGUMENTS"
            INPUT_TYPE="directory"
            # Generate requirements based on directory analysis
            analyze_directory_for_requirements "$ARGUMENTS"
        elif [[ "$ARGUMENTS" == *","* ]]; then
            echo "📝 Processing feature list: $ARGUMENTS"
            REQUIREMENTS="$ARGUMENTS"
            INPUT_TYPE="feature_list"
        else
            echo "🎯 Processing project scope: $ARGUMENTS"
            PROJECT_SCOPE="$ARGUMENTS"
            INPUT_TYPE="scope"
        fi
    else
        echo "❓ No requirements provided. Starting interactive requirements gathering..."
        INPUT_TYPE="interactive"
        gather_requirements_interactively
    fi
}

analyze_directory_for_requirements() {
    local dir_path="$1"
    echo "🔍 Analyzing $dir_path for potential features..."
    
    # Look for TODOs, FIXMEs, and feature requests in code
    grep -r "TODO\|FIXME\|FEATURE" "$dir_path" 2>/dev/null | head -20
    
    # Check for incomplete implementations
    grep -r "NotImplemented\|placeholder\|stub" "$dir_path" 2>/dev/null | head -10
    
    # Look for test files that might indicate planned features
    find "$dir_path" -name "*test*" -o -name "*spec*" | head -10
}

gather_requirements_interactively() {
    echo "🤔 Let's gather your project requirements interactively..."
    echo "Please describe the features you want to implement:"
    echo "(Enter each feature on a new line, press Ctrl+D when done)"
    REQUIREMENTS=$(cat)
}
```

## Planning Methodology

### Phase 1: Feature Analysis and Classification
1. **Feature Decomposition**
   - Break down complex features into atomic components
   - Identify shared dependencies
   - Map database schema changes
   - Analyze API surface modifications

2. **Dependency Mapping**
   - Identify which features depend on others
   - Map shared components and utilities
   - Analyze database migration dependencies
   - Check for API contract changes

3. **Conflict Risk Assessment**
   - File modification overlap analysis
   - Database schema conflict potential
   - API endpoint collision detection
   - Configuration file conflicts

### Phase 2: Worktree Strategy Design
1. **Grouping Strategy**
   - Bundle related features that can share worktree
   - Separate conflicting features into different worktrees
   - Identify features that must be sequential
   - Plan parallel development streams

2. **Execution Order Planning**
   - Define development phases
   - Plan integration checkpoints
   - Schedule dependency deliveries
   - Set merge strategy

process_feature_list() {
    local feature_string="$1"
    echo "📋 Processing feature list..."
    
    # Split comma-separated features
    IFS=',' read -ra FEATURES <<< "$feature_string"
    
    for feature in "${FEATURES[@]}"; do
        # Clean up whitespace
        feature=$(echo "$feature" | xargs)
        echo "  ✓ Feature identified: $feature"
        
        # Analyze feature for complexity and dependencies
        analyze_feature_complexity "$feature"
    done
}

analyze_feature_complexity() {
    local feature="$1"
    
    # Determine complexity based on keywords
    if [[ "$feature" == *"auth"* ]] || [[ "$feature" == *"login"* ]]; then
        echo "    🔐 Authentication feature - High complexity, foundational"
    elif [[ "$feature" == *"user"* ]] || [[ "$feature" == *"profile"* ]]; then
        echo "    👤 User management feature - Medium complexity"
    elif [[ "$feature" == *"api"* ]] || [[ "$feature" == *"endpoint"* ]]; then
        echo "    🔌 API feature - Medium complexity"
    elif [[ "$feature" == *"dashboard"* ]] || [[ "$feature" == *"analytics"* ]]; then
        echo "    📊 Analytics feature - Low-medium complexity"
    else
        echo "    🔍 General feature - Requires detailed analysis"
    fi
}
```

## Analysis Process

### Step 1: Requirements Validation and Expansion
```bash
validate_and_expand_requirements() {
    echo "🔍 Validating and expanding requirements..."
    
    case $INPUT_TYPE in
        "file")
            validate_requirements_file "$ARGUMENTS"
            ;;
        "feature_list")
            process_feature_list "$REQUIREMENTS"
            ;;
        "directory")
            analyze_existing_codebase_for_context "$SCOPE_PATH"
            ;;
        "scope")
            expand_project_scope "$PROJECT_SCOPE"
            ;;
        "interactive")
            structure_interactive_requirements
            ;;
    esac
}

expand_project_scope() {
    local scope="$1"
    echo "🎯 Expanding project scope: $scope"
    
    case "$scope" in
        "frontend"|"ui"|"client")
            echo "Frontend scope detected - analyzing UI components, state management, routing"
            REQUIREMENTS="UI Components,State Management,Routing,User Interface,Responsive Design"
            ;;
        "backend"|"server"|"api")
            echo "Backend scope detected - analyzing API endpoints, database, services"
            REQUIREMENTS="API Endpoints,Database Models,Business Logic,Authentication,Data Validation"
            ;;
        "fullstack"|"complete"|"all")
            echo "Full-stack scope detected - comprehensive feature analysis"
            REQUIREMENTS="Frontend UI,Backend API,Database,Authentication,User Management,Analytics"
            ;;
        "mobile"|"app")
            echo "Mobile scope detected - analyzing mobile-specific features"
            REQUIREMENTS="Mobile UI,Offline Support,Push Notifications,Mobile Authentication,Performance Optimization"
            ;;
        *)
            echo "Custom scope: $scope - analyzing for relevant features"
            REQUIREMENTS="$scope"
            ;;
    esac
}
```

### Step 2: Feature Classification
For each feature, analyze:
- **File Impact**: Which files will be modified
- **Database Impact**: Schema changes required
- **API Impact**: New/modified endpoints
- **Dependency Impact**: What it depends on and what depends on it
- **Risk Level**: Complexity and change magnitude

### Step 3: Conflict Matrix Generation
Create matrix showing potential conflicts between features:
- **File Conflicts**: Features modifying same files
- **Schema Conflicts**: Database changes that conflict
- **API Conflicts**: Endpoint or contract conflicts
- **Logic Conflicts**: Business logic interdependencies

### Step 4: Optimization Algorithm
Apply these rules to optimize worktree allocation:
1. **Isolation Rule**: Separate high-conflict features
2. **Dependency Rule**: Dependencies must complete first
3. **Cohesion Rule**: Related features work better together
4. **Resource Rule**: Balance complexity across worktrees

Remember to think ultra hard about dependencies and conflicts. The goal is to maximize parallel development while minimizing integration complexity.

## EXECUTION GUIDELINES

### Multi-Agent Coordination
Use multiple specialized sub agents for both planning and execution phases to ensure comprehensive analysis and high-quality output. Deploy sub agents in parallel when possible to optimize workflow efficiency.

### Requirements Preservation
Before implementing any changes, modifications, or new features:
1. Thoroughly analyze existing application requirements and functionality
2. Ensure all proposed changes maintain backward compatibility
3. Verify that new implementations do not compromise or modify existing core functionality
4. If conflicts arise between new requirements and existing functionality, STOP and request explicit guidance on how to proceed

### Implementation Standards
When developing new features:
- Implement actual functionality, never create simulations or placeholder code
- If a requested feature is implementable, build the complete working solution
- If a requested feature is not implementable, clearly state "cannot be implemented" with specific technical reasons
- Do not create mock implementations that simulate the requested behavior

### Testing Approach
When conducting tests:
- Maintain complete objectivity in test execution and result reporting
- Focus on accurately mapping what works and what does not work
- Report actual test results, not idealized outcomes
- Do not manipulate tests to achieve expected results
- Document failures and issues honestly for subsequent debugging and resolution
- The goal is comprehensive understanding of system behavior, not perfect initial results

Always think ultra hard about the complete implications of any changes before proceeding with implementation.
