Does this skill help with security best practices?

Yes, it enforces a security-first approach by guiding you through setting up pre-commit hooks for secret detection and providing a security checklist for input sanitization.

Can I build complex tools with multiple subcommands?

Absolutely. The skill includes specific implementation guides for subcommand architectures, allowing you to build tools as complex as git or docker.

Which programming languages are supported by the CLI Tool skill?

The skill provides optimized patterns for the three most popular CLI ecosystems: Rust (using clap), Python (using Typer), and Node.js (using Commander or Yargs).

Does it support interactive terminal features?

Yes, it provides code snippets and best practices for interactive prompts, progress bars, and formatted output (JSON, Tables, and Text) using libraries like Rich and Dialoguer.

How does the skill handle CLI testing?

It implements a TDD (Test-Driven Development) workflow using language-specific tools like assert_cmd for Rust and CliRunner for Python to ensure your interface works as expected.
