What problem does it solve?

Managing Python codebases often suffers from tangled dependencies, god classes, and unclear ownership that hinder maintenance and safe refactors. This skill provides structured guidance to design clear module boundaries and contracts, improving understandability and evolution over time.

Core Features & Use Cases

• Clear module ownership: delineates responsibilities and data contracts between modules to reduce cross-cutting coupling.
• Readability-driven boundaries: promotes predictable interfaces and explicit data flow to ease onboarding and future changes.
• Use Case: when planning a large refactor across multiple packages, apply these rules to partition concerns, isolate changes, and maintain testability.

Quick Start

Start by defining explicit module boundaries and contracts in your Python project to guide refactors and improve maintainability.
