What problem does it solve?

Building CLI tools with multiple commands often leads to scattered argument parsing, inconsistent entry points, and unclear parameter flow. This skill standardizes the structure to deliver predictable, testable CLIs.

Core Features & Use Cases

• Single entry point dispatcher: Routes commands from a single main.py to dedicated handlers.
• Explicit parameter flow: Commands receive concrete parameters, not environment reads, improving testability.
• Command organization: Clear separation between entry point, parsing layer, and business logic.
• Use Case: Create a multi-command tool (e.g., greet, status, config) with easy extension and consistent behavior.

Quick Start

Build a minimal CLI with a main.py dispatcher and a sample command, then run: python -m mypackage greet --name Alice
