System Documentation

What problem does it solve?

Extracts the business logic that accumulates in Typer/Click CLI modules beyond 300 LOC, enabling a clean separation into a testable service layer.

Core Features & Use Cases

  • Extracts logic into a dedicated service.py to isolate core functionality from CLI presentation
  • Defines translation rules to map CLI concerns into service layer interfaces, improving testability and reuse
  • Supports reuse of the service across web UIs, APIs, and SDKs without CLI dependencies

Quick Start

Refactor a Typer/Click CLI module by moving business logic into service.py and run tests to verify the new service layer.
