Does it handle shell completions?

Absolutely. The skill can generate shell completion scripts for various shells (Bash, Zsh, Fish) to improve the end-user experience.

Can this skill help with interactive terminal UI (TUI) elements?

Yes, it provides guidance for adding interactive prompts, progress bars, spinners, and complex TUI layouts using libraries like Bubbletea or Inquirer.

How does it ensure my CLI works in CI/CD environments?

The skill follows constraints to ensure non-interactive modes are supported and interactive prompts are bypassed or handled via flags when a TTY is not detected.

Which programming languages does the CLI Developer skill support?

This skill supports major ecosystems including Node.js (Commander, Yargs, oclif), Python (Typer, Click, argparse), and Go (Cobra, Viper, Bubbletea).

What are the performance standards for the generated tools?

The skill prioritizes a fast startup time, aiming for under 50ms, and ensures efficient resource handling for high-performance terminal applications.
