How are terminal colors handled?

The skill provides ANSI escape code patterns that allow you to add colors, bold text, and dim formatting to your terminal output without adding external dependencies.

Does this skill require external libraries like Commander or Yargs?

No, this skill focuses on building lightweight, high-performance CLIs with minimal dependencies using built-in runtime modules.

Does it support automated piping and scripting?

Yes, it includes specific patterns for implementing a --json flag and handling output streams to ensure compatibility with shell pipelines.

Can I use these CLI patterns with Node.js instead of Bun?

Yes, most patterns use standard Node.js APIs like util.parseArgs. However, specific features like the '$' shell execution syntax are unique to the Bun runtime.

How do I make my Bun CLI tool globally executable?

The skill provides guidance on using the 'bin' field in your package.json and adding the correct shebang line to your entry script.
