SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill guides clean architecture with a strict 200-line file limit, ensuring modular design and testable structure.

Core Features & Use Cases

200-line limit — No file exceeds 200 lines of code
Split when exceeded — Convert to folder or multiple files
Plan first, code later — Design architecture before implementation
Single responsibility — Each module does one thing well
Real tests only — No mocks, test actual behavior

Quick Start

Audit your codebase, identify files over 200 lines, and split them into modular components to enforce the 200-line rule.

FAQPage Schema

What is a strict line limit for enforcing clean architecture and modular code?▼

A strict 200-line limit per file enforces clean architecture by forcing modular design. When a file exceeds this threshold, you must split it into a folder or multiple files to maintain single responsibility and testable structure.

How do I refactor large code modules into modular components?▼

To refactor large modules, audit your codebase to identify files over 200 lines, then split them into smaller modular components. This approach ensures each module does one thing well, improving overall code quality and maintainability.

Why use real tests instead of mocks for code quality and architecture?▼

Using real tests instead of mocks validates actual behavior rather than simulated interactions. This clean architecture practice ensures your modular design remains genuinely testable and reliable during refactoring.

When do I need to split code files during software development?▼

You need to split code files when starting new features, refactoring large modules, or planning module structure. Enforcing a 200-line limit ensures maintainable code by converting oversized files into folders or multiple modular files.

Does planning architecture before implementation improve code maintainability?▼

Planning architecture before implementation ensures maintainable code by establishing a plan-first design approach. This prevents large modules from forming and promotes single responsibility across components before development begins.

Limitations of enforcing a 200-line file limit for clean architecture?▼

The 200-line limit requires rigid adherence, meaning any file exceeding it must be converted to a folder or multiple files. This strict constraint may increase file count but ensures modular design and testable structure.
