name: sdlc-development description: Guides implementation phase. Use when writing code, implementing features, or building functionality. Ensures code quality, testing, and documentation.

SDLC Development Skill

When to Use This Skill

• Implementing new features
• Writing code
• Building functionality
• Refactoring existing code
• Adding new components

Development Workflow

1. Setup

• Review specification: Understand what to build
• Create feature branch: \git checkout -b feature/name\
• Set up environment: Install dependencies
• Review existing code: Understand current patterns

2. Implementation

Follow these principles:

Code Quality:

• Write clean, readable code
• Use meaningful variable names
• Follow project conventions
• Add comments for complex logic

Error Handling:

• Handle expected errors gracefully
• Provide helpful error messages
• Log errors appropriately
• Don't crash on edge cases

Project Patterns:

• Match existing code style
• Reuse existing components
• Follow DRY (Don't Repeat Yourself)
• Keep functions small and focused

3. Testing

• Write unit tests: Test individual functions
• Test edge cases: Empty inputs, null values, large datasets
• Manual testing: Actually try the feature
• Integration testing: Test with other components

4. Documentation

• Update README: Add new feature to docs
• Add code comments: Explain why, not what
• Document API changes: Update interface docs
• Create examples: Show how to use the feature

Code Quality Checklist

Before committing:

• Code follows style guide
• Has error handling
• Includes tests
• Documented (README + comments)
• No hardcoded values (use config)
• No console.log / debug code
• Tested manually
• Git commit message is clear

Example Usage

Input: "Implement CSV export for sponsor results"

Output:

• Complete implementation
• Unit tests
• Documentation
• Usage examples
