SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Reorganize sprawling codebases into clear, domain-aligned package boundaries using MECE grouping to reduce coupling and improve maintainability.

Core Features & Use Cases

  • Chunk Down: identify atomic responsibilities and surface concise public APIs.
  • Chunk Up: group related responsibilities into domain-oriented packages with meaningful names.
  • Phase-driven guidance: provides a structured progression from decomposition to packaging and interface definition for maintainable architectures.
  • Use Case: ideal for refactoring monoliths or large modules into modular architectures to support scalable feature work.

Quick Start

Start by listing all public types and functions in the codebase, then group them into domain-oriented, MECE packages based on responsibilities.

FAQPage Schema
How do I refactor a monolithic codebase into modular domain-oriented packages?

Refactoring a monolithic codebase into modular packages requires listing all public types and functions, then grouping them into domain-aligned MECE partitions to reduce coupling and establish maintainable boundaries.

What is MECE partitioning in code architecture and when should I apply it?

MECE partitioning in code architecture is a grouping method ensuring package responsibilities are mutually exclusive and collectively exhaustive. Apply it during mid-to-large project refactoring to enforce low coupling and clear modular boundaries.

Can I use this package design approach for Rust, Java, and TypeScript projects?

Yes, you can use this package design approach for Rust, Java, and TypeScript projects. It applies phase-driven guidance for decomposition and packaging across multiple languages to support scalable feature work.

What is the best way to define clear public interfaces for code modules?

The best way to define clear public interfaces for code modules is using a chunk down phase to identify atomic responsibilities and surface concise APIs, followed by a chunk up phase to group them into meaningful domain packages.

When should I not use MECE package restructuring for my codebase?

You should not use MECE package restructuring for small or simple codebases. It is designed for mid-to-large projects needing modular boundaries and low coupling, so applying it to trivial code may introduce unnecessary architectural overhead.
