name: programming description: Write, debug, review and explain source code following object-oriented best practices, DDD principles, and comprehensive testing standards. Use when writing new code, refactoring, debugging, code review, or explaining programming concepts.

Programming

Master programming principles to build high-quality, maintainable, testable and production-ready software following object-oriented design, Domain-Driven Design (DDD) tactical patterns, and rigorous testing standards.

Quick Start

This Skill provides comprehensive coding rules organized by category with severity levels. Before any coding task:

1. Read CODING-RULES.md to understand all applicable rules
2. STRICTLY follow this rules while producing or reviewing a source code
3. RESPECT rules by severity: Critical → High → Medium → Low
4. When conflicts arise: Higher severity wins, then defer to existing code patterns

When to Use This Skill

• Writing new features or components
• Refactoring legacy code
• Debugging and fixing bugs (test-first approach)
• Reviewing code for quality, maintainability, and standards compliance
• Explaining design patterns, architectural decisions, and best practices
• Designing class hierarchies and interfaces
• Creating comprehensive test suites

Rule Categories Overview

The CODING-RULES.md file contains detailed rules in these categories:

• Architecture & Structure [A]
• Code Style & Patterns [S]
• Class Requirements [C]
• Method Requirements [M]
• Documentation [D]
• Testing Standards [T]
• AI Code Generation Process [AI]

Rule Severity Levels

• [C]ritical: Must never be violated
• [H]igh: Should almost never be violated
• [M]edium: Follow unless good reason not to
• [L]ow: Guidelines and preferences

Conflict Resolution

When rules conflict:

1. Higher severity always wins
2. If same severity, follow existing code patterns
3. Critical rules are absolute
4. Document any necessary deviations with strong justification
