When designing a generator for extension, which feature should you expose to users to customize its operation?

• A. Options to control behavior
• B. Hidden internal flags
• C. No options
• D. Fixed behavior only

Answer: (A)

Exposing options to control behavior gives users the ability to tailor the generator to their specific project needs. When you create an extension, different projects often require different setups, templates, or tools. By providing configurable options—with sensible defaults and a simple way to customize them, such as prompts or a config file—you empower users to choose features, adjust scaffolding details, and automate their workflow. This flexibility makes the generator useful in a wider range of scenarios, from small personal projects to large teams with strict conventions.

Hidden internal flags aren’t user-friendly because they aren’t discoverable or understandable, so they can’t be effectively used. No options or fixed behavior keeps users stuck with a one-size-fits-all approach, which reduces practicality and adoption.
