SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you design and implement command-line tools that are easy to use, fast to start, and reliable across operating systems. It reduces friction when you need argument parsing, subcommands, interactive prompts, progress feedback, or shell completions.

Core Features & Use Cases

  • CLI Architecture: Plan clear command hierarchies, flags, arguments, and configuration layers for maintainable tools.
  • Interactive Experience: Add prompts, confirmations, spinners, and progress bars that feel polished in terminal workflows.
  • Cross-Platform Delivery: Build CLIs for Node.js, Python, and Go with strong error handling, help text, versioning, and completion support.
  • Use Case: A developer building a deploy tool can use this Skill to define subcommands, validate inputs early, support both scripted and interactive use, and ship a better terminal experience.

Quick Start

Use the cli-developer skill to design the command structure, flags, prompts, and completion strategy for my CLI project.

FAQPage Schema
How do I design a command-line interface with subcommands and flags?▼

You design a CLI by planning clear command hierarchies, flags, and arguments. This Skill helps structure subcommands, validate inputs early, and define configuration layers to ensure maintainable developer tools across Node.js, Python, and Go.

What's the best way to add interactive prompts and progress indicators to a CLI?▼

Adding interactive prompts and progress indicators improves the terminal workflow experience. You can implement confirmations, spinners, and progress bars that feel polished, while ensuring support for non-interactive mode for scripted environments.

Does this CLI design approach support Node.js, Python, and Go projects?▼

Yes, this approach supports cross-platform delivery for Node.js, Python, and Go projects. It ensures strong error handling, help text, versioning, and shell completion support across these different runtime environments.

How do I make a CLI tool work in both interactive and scripted non-interactive modes?▼

Making a CLI tool work in both modes requires supporting non-interactive mode alongside interactive prompts. You validate inputs early and provide graceful error handling so the tool functions reliably in automated scripts and manual terminal workflows.

Why does my CLI tool need shell completion and fast startup performance?▼

Shell completion and fast startup performance reduce user friction and make terminal tools feel reliable. Designing CLIs with quick initialization and completion support ensures a polished, efficient experience across different operating systems.
