CLI Argument Parser

Parse command-line arguments with flags, options, subcommands, and help text in any language.

Usage

Describe the CLI interface you want and this skill will implement argument parsing.

Examples

• "Parse --input, --output, and --verbose flags in a bash script"
• "Build a Node.js CLI with subcommands using commander"
• "Implement argument parsing with type validation in Python"

Guidelines

• Provide sensible defaults for optional arguments
• Generate help text automatically from argument definitions
• Validate argument types and ranges before processing
• Support both short and long flag formats
• Exit with meaningful error messages for invalid arguments
