SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Building command-line tools from scratch involves many decisions about command structure, argument parsing, output styling, and bundling. This Skill guides the AI through a structured process for creating well-organized CLI applications in JavaScript and TypeScript for PowerShell environments. ## Core Features & Use Cases - CLI Structure Design: Plans commands, options, and arguments in a logical, intuitive hierarchy before writing code. - Library-Guided Implementation: Uses commander for argument parsing, chalk for styled terminal output, and bun for building and bundling. - Testing and Documentation Workflow: Covers testing edge cases, handling errors gracefully, and producing user-facing documentation. - Use Case: Ask the AI to scaffold a CLI tool that converts files between formats, and it will design the command tree, implement it with commander and chalk, bundle it with bun, and document usage. ## Quick Start Use the Cli-Expert skill to build a CLI tool in TypeScript that renames batches of files with styled output and commander-based commands.

FAQPage Schema
How do I build a CLI tool in TypeScript with commander?▼

Define your command tree with commander by registering commands, options, and arguments, then attach action handlers for each command. Plan the structure first so commands are organized logically, then test edge cases and document usage.

What is chalk used for in CLI applications?▼

Chalk styles terminal output with colors, bold text, and other formatting to make CLI output more readable. It is commonly combined with commander to highlight errors, success messages, and structured results in the console.

Can I use bun to bundle a Node.js CLI tool?▼

Yes, bun can build and bundle JavaScript and TypeScript CLI applications into distributable files. It handles dependency resolution and compilation, producing output suitable for distribution or direct execution.

How do I handle errors gracefully in a CLI tool?▼

Validate arguments early, wrap risky operations in try-catch blocks, and print clear styled error messages with chalk instead of raw stack traces. Test edge cases like missing files and invalid flags to ensure a smooth user experience.

Does this approach work for PowerShell users on Windows?▼

Yes, the skill targets PowerShell-based environments, so generated CLI tools are designed to run in Windows terminals. Commander and chalk both work cross-platform, including PowerShell, cmd, and Unix shells.
