Framework Boilerplate Generator

I'll generate framework-specific boilerplate code following best practices and conventions for React, Vue, Next.js, Express, FastAPI, Django, and more.

Arguments: $ARGUMENTS - component/route/model name and type

Supported Frameworks:

• Frontend: React, Vue, Next.js, Angular, Svelte
• Backend: Express, Fastify, NestJS, FastAPI, Django
• Full-stack: Next.js, Remix, SvelteKit

Token Optimization

This skill uses multiple optimization strategies to minimize token usage while maintaining comprehensive boilerplate generation:

1. Framework Detection Caching (400 token savings)

Pattern: Cache framework detection results to avoid repeated file system checks

# Cache file: .boilerplate-framework.cache
# Format: framework_name
# TTL: 24 hours (framework rarely changes)

if [ -f ".boilerplate-framework.cache" ] && [ $(($(date +%s) - $(stat -c %Y .boilerplate-framework.cache))) -lt 86400 ]; then
    FRAMEWORK=$(cat .boilerplate-framework.cache)
    # 20 tokens vs 420 tokens for full detection
else
    FRAMEWORK=$(detect_framework)  # Full detection (420 tokens)
    echo "$FRAMEWORK" > .boilerplate-framework.cache
fi

Savings:

• Cached: ~20 tokens (read cache file)
• Uncached: ~420 tokens (package.json/requirements.txt checks, multiple Grep operations)
• 400 token savings (95%) for subsequent runs

2. Template Library Approach (2,500 token savings)

Pattern: Use comprehensive pre-defined templates instead of LLM-generated code

# Instead of: LLM-generated boilerplate (3,000+ tokens)
# Use: Template library (500 tokens)

# Template files stored in skill
TEMPLATE_DIR="templates/$FRAMEWORK"

generate_component() {
    local component_name="$1"
    local template_file="$TEMPLATE_DIR/component.template.tsx"

    # Simple variable substitution (100 tokens)
    sed "s/\${COMPONENT_NAME}/$component_name/g" "$template_file"
}

Savings:

• Template-based: ~500 tokens (file read + substitution)
• LLM-generated: ~3,000 tokens (full code generation with analysis)
• 2,500 token savings (83%) per component

3. Grep-Based Configuration Detection (300 token savings)

Pattern: Use Grep to detect project configuration instead of reading files

# Instead of: Read package.json/requirements.txt fully (500 tokens)
# Use: Grep for specific patterns (200 tokens)

# Detect React
HAS_REACT=$(grep -q "\"react\":" package.json && echo "true" || echo "false")

# Detect TypeScript
HAS_TS=$(grep -q "\"typescript\":" package.json && echo "true" || echo "false")

# Detect testing framework
HAS_JEST=$(grep -q "\"jest\":" package.json && echo "true" || echo "false")

Savings:

• Grep approach: ~200 tokens (pattern matching)
• Full file read: ~500 tokens (read and parse JSON)
• 300 token savings (60%)

4. Incremental Scaffolding (1,200 token savings)

Pattern: Generate only requested component type, not entire feature

# Instead of: Full feature scaffolding (4,000+ tokens)
# - Component + styles + tests + stories + types
# Generate: Only component (800 tokens)

case $COMPONENT_TYPE in
    component)
        generate_component "$COMPONENT_NAME"  # 800 tokens
        ;;
    route)
        generate_route "$COMPONENT_NAME"  # 900 tokens
        ;;
    full)
        generate_component "$COMPONENT_NAME"
        generate_styles "$COMPONENT_NAME"
        generate_tests "$COMPONENT_NAME"
        generate_types "$COMPONENT_NAME"  # 4,000 tokens
        ;;
esac

Savings:

• Component only: ~800 tokens
• Full feature: ~4,000 tokens
• 1,200 token savings (75%) when generating single component

5. Early Exit for Existing Components (90% savings)

Pattern: Check if component already exists before generating

# Quick check: Does component exist?
case $FRAMEWORK in
    react)
        component_path="src/components/${COMPONENT_NAME}/${COMPONENT_NAME}.tsx"
        ;;
    nextjs)
        component_path="app/${COMPONENT_NAME}/page.tsx"
        ;;
esac

if [ -f "$component_path" ]; then
    echo "⚠️  Component $COMPONENT_NAME already exists at $component_path"
    read -p "Overwrite? (y/n): " confirm
    if [ "$confirm" != "y" ]; then
        echo "✓ Keeping existing component"
        exit 0  # 200 tokens total
    fi
fi

# Otherwise: Full generation (3,500+ tokens)

Savings:

• Existing component: ~200 tokens (early exit)
• Full generation: ~3,500+ tokens
• 3,300+ token savings (94%) when component exists

6. Framework-Specific Template Caching (800 token savings)

Pattern: Cache loaded templates per framework

# Cache file: .boilerplate-templates-${FRAMEWORK}.cache
# Contains pre-loaded templates for the framework
# TTL: 24 hours

load_templates() {
    local cache_file=".boilerplate-templates-${FRAMEWORK}.cache"

    if [ -f "$cache_file" ]; then
        source "$cache_file"  # 150 tokens
        return
    fi

    # Load all templates for framework (950 tokens)
    case $FRAMEWORK in
        react)
            TEMPLATE_COMPONENT=$(cat templates/react/component.tsx)
            TEMPLATE_TEST=$(cat templates/react/test.tsx)
            TEMPLATE_STYLES=$(cat templates/react/styles.css)
            ;;
        nextjs)
            TEMPLATE_PAGE=$(cat templates/nextjs/page.tsx)
            TEMPLATE_API=$(cat templates/nextjs/api-route.ts)
            ;;
    esac

    declare -p TEMPLATE_* > "$cache_file"
}

Savings:

• Cached templates: ~150 tokens
• Load templates: ~950 tokens (multiple file reads)
• 800 token savings (84%) for subsequent runs

7. Component Inventory Tracking (400 token savings)

Pattern: Track generated components to avoid duplicates

# Cache file: .boilerplate-generated.cache
# Format: framework:component_type:component_name:file_path
# TTL: Session-based (cleared manually)

is_component_generated() {
    local component_name="$1"
    local component_type="$2"
    grep -q "^$FRAMEWORK:$component_type:$component_name:" .boilerplate-generated.cache 2>/dev/null
}

# Track generated components
if ! is_component_generated "$COMPONENT_NAME" "$COMPONENT_TYPE"; then
    generate_boilerplate
    echo "$FRAMEWORK:$COMPONENT_TYPE:$COMPONENT_NAME:$component_path" >> .boilerplate-generated.cache
else
    echo "  ✓ $COMPONENT_NAME already generated"
fi

Savings:

• Skip duplicate: ~50 tokens (cache check)
• Generate new: ~450 tokens (template processing)
• 400 token savings (89%) for duplicate prevention

8. Test File Generation Optimization (600 token savings)

Pattern: Generate minimal test boilerplate with placeholders

# Instead of: Comprehensive test suite (1,200 tokens)
# Use: Minimal test template with TODOs (600 tokens)

generate_minimal_test() {
    local component_name="$1"

    cat <<EOF
import { render, screen } from '@testing-library/react';
import { ${component_name} } from './${component_name}';

describe('${component_name}', () => {
  it('renders without crashing', () => {
    render(<${component_name} />);
  });

  // TODO: Add more tests
});
EOF
}

Savings:

• Minimal test: ~200 tokens (basic structure)
• Comprehensive test: ~800 tokens (multiple test cases)
• 600 token savings (75%)
• Users can expand tests as needed

9. Real-World Token Usage Distribution

Typical Scenarios:

1. First Run - Single Component (2,000-3,000 tokens)

   • Framework detection: 420 tokens
   • Load templates: 950 tokens
   • Generate component: 800 tokens
   • Generate test: 200 tokens
   • Generate styles: 150 tokens
   • Total: ~2,520 tokens

2. Subsequent Run - Same Framework (800-1,500 tokens)

   • Framework detection (cached): 20 tokens
   • Load templates (cached): 150 tokens
   • Generate component: 800 tokens
   • Generate test: 200 tokens
   • Total: ~1,170 tokens

3. Component Exists (150-250 tokens)

   • Framework detection (cached): 20 tokens
   • Check existing: 100 tokens
   • Early exit: 50 tokens
   • Total: ~170 tokens

4. Full Feature Scaffold (4,000-6,000 tokens)

   • Framework detection: 420 tokens
   • Load templates: 950 tokens
   • Generate component: 800 tokens
   • Generate test: 800 tokens
   • Generate styles: 150 tokens
   • Generate types: 400 tokens
   • Generate story: 300 tokens
   • Total: ~3,820 tokens

5. API Route Only (600-1,000 tokens)

   • Framework detection (cached): 20 tokens
   • Load API template: 150 tokens
   • Generate route: 600 tokens
   • Total: ~770 tokens

Expected Token Savings:

• Average 53% reduction from baseline (3,000 → 1,400 tokens)
• 94% reduction when component already exists
• Aggregate savings: 1,500-2,000 tokens per boilerplate generation

Optimization Summary

Strategy	Savings	When Applied
Framework detection caching	400 tokens (95%)	Subsequent runs
Template library approach	2,500 tokens (83%)	Always
Grep-based config detection	300 tokens (60%)	Always
Incremental scaffolding	1,200 tokens (75%)	Component-only generation
Early exit for existing	3,300 tokens (94%)	Component exists
Template caching	800 tokens (84%)	Subsequent runs
Component inventory	400 tokens (89%)	Duplicate prevention
Minimal test generation	600 tokens (75%)	Test files

Key Insight: The template library approach combined with framework caching provides 50-60% token reduction while maintaining production-ready boilerplate quality. Early exit patterns provide 94% savings when components already exist.

Best Practices

Code Quality:

• Follow framework conventions
• Include comprehensive types
• Add proper error handling
• Write meaningful documentation

Integration Points:

• /test - Generate tests for boilerplate
• /scaffold - Complete feature scaffolding
• /inline-docs - Add documentation

What I'll Actually Do

1. Detect framework - Identify project type
2. Parse arguments - Component name and type
3. Generate boilerplate - Framework-specific code
4. Include tests - Unit/integration tests
5. Add documentation - JSDoc/docstrings
6. Follow conventions - Framework best practices

Important: I will NEVER add AI attribution.
