How is help text generated for my CLI tool?

The module automatically handles the --help and --version flags, generating formatted documentation based on your defined arguments, flags, and descriptions.

Can I use dependency injection with my CLI commands?

Yes, this skill demonstrates how to use Command.provide, Command.provideEffect, and Command.provideSync to inject services and layers directly into your command logic.

Does it support nested subcommands?

Absolutely. You can create complex command hierarchies using Command.withSubcommands to nest multiple specialized commands under a single parent application.

Are positional arguments required by default?

Yes, arguments are required and parsed in order by default, but you can use combinators like Argument.optional or Argument.withDefault to change this behavior.

What is the main benefit of using the Effect CLI skill?

It provides a type-safe framework for building CLI applications, ensuring that all arguments and flags are validated at runtime and correctly typed within your command handlers.

Builds type-safe, validated command-line applications with built-in dependency injection using the Effect ecosystem.

This skill enables the creation of robust, production-grade command-line interfaces using Effect's CLI module. It provides a structured approach to defining commands, validating positional arguments, and managing named flags with full type safety. By integrating with Effect's core features, it allows developers to build complex CLI hierarchies with nested subcommands while leveraging powerful patterns like dependency injection and functional error handling for terminal-based utilities.
