Scaffolding Skill

Generate boilerplate code that matches existing project conventions.

Workflow

1. Detect Project Conventions

Before generating, find existing patterns:

# Find similar files
find . -name "*.tsx" -path "*/components/*" | head -5

# Check file structure
ls -la src/components/

# Look at existing code
cat src/components/Button/Button.tsx

Key conventions to detect:

• File/folder structure (flat vs nested)
• Naming conventions (PascalCase, camelCase, kebab-case)
• Export style (default vs named)
• Import style (relative vs aliases)
• Test co-location (same folder or separate)
• Styling approach (CSS Modules, styled-components, Tailwind)

2. Match Project Style

Always match:

3. Generate Code

Include what's standard in the project:

• [ ] Main file (component/module)
• [ ] Types/interfaces (if TypeScript)
• [ ] Test file (if tests exist nearby)
• [ ] Index file (if using barrel exports)
• [ ] Styles (if using CSS Modules)
• [ ] Stories (if using Storybook)

4. Verify Output

Check generated code:

• Follows detected conventions
• Imports resolve correctly
• TypeScript compiles (if applicable)
• Matches similar files in project

Quick Reference

Scaffolding Commands

Ask for scaffolding like:

• "Create a new UserProfile component"
• "Scaffold a PaymentService"
• "Generate a useAuth hook"
• "Create a products API route"

What to Generate

File Detection Patterns

# Detect React style
grep -l "React.FC\|: FC<" src/**/*.tsx  # Typed FC
grep -l "function.*Props" src/**/*.tsx  # Function with props

# Detect test pattern
ls src/**/*.test.* 2>/dev/null  # Co-located
ls tests/ 2>/dev/null            # Separate folder

# Detect styling
ls src/**/*.module.css 2>/dev/null  # CSS Modules
grep "styled\." src/**/*.tsx         # styled-components
grep "className=" src/**/*.tsx       # Tailwind/CSS

Templates

Templates are available for common stacks:

• react.md - React component templates
• node.md - Node.js/Express templates
• python.md - Python module templates

Best Practices

Do:

• Match existing patterns exactly
• Include all files that similar modules have
• Use the same folder structure
• Copy import styles from nearby files

Don't:

• Introduce new patterns
• Add "improvements" to the template
• Skip files that peers have (like tests)
• Use different naming conventions

Example

Request: "Create a UserCard component"

Detection:

Existing components use:
- Folder structure: ComponentName/index.tsx
- Style: CSS Modules (ComponentName.module.css)
- Tests: ComponentName.test.tsx in same folder
- Types: Props interface in same file
- Exports: default export

Generated files:

src/components/UserCard/
├── index.tsx
├── UserCard.module.css
└── UserCard.test.tsx

index.tsx matches existing style:

import styles from './UserCard.module.css';

interface UserCardProps {
  name: string;
  email: string;
}

export default function UserCard({ name, email }: UserCardProps) {
  return (
    <div className={styles.container}>
      <h3 className={styles.name}>{name}</h3>
      <p className={styles.email}>{email}</p>
    </div>
  );
}
