Python CLI with Typer

Overview

Use Typer for ergonomic CLI construction. Core principle: keep command wiring thin, explicit, and testable while moving business logic into regular Python functions.

Use When

• Building a Python CLI with Typer.
• Adding commands, arguments, options, prompts, or confirmations.
• Wiring a module entry point or console script.
• Testing CLI behavior separately from business logic.
