SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires commander, and includes references (resource) components.

What problem does it solve?

This Skill eliminates the time-consuming process of manually building command-line interfaces from scratch, allowing you to generate production-ready TypeScript CLIs in minutes instead of hours.

Core Features & Use Cases

Intelligent Tier Selection: Automatically chooses the right complexity level for your CLI needs.
Complete Implementation: Generates fully functional CLIs with type safety, error handling, and comprehensive documentation.
Use Case: When you need a CLI for the GitHub API, simply describe your requirements and get a complete ghcli tool with repos, issues, and search commands.
Best Practices Built-in: Follows proven patterns from production CLIs like llcli.

Quick Start

Use the system-createcli skill to generate a CLI for the Notion API that can list databases and create pages.

FAQPage Schema

How do I generate a production-ready TypeScript CLI without building it from scratch?▼

Generate production-quality TypeScript CLIs from user requirements using automated scaffolding. The Skill creates fully functional tools with type safety, error handling, documentation, and environment-driven configuration in minutes, supporting tiered complexity levels from simple llcli-style commands to full Commander.js implementations.

Can I use Commander.js to build a multi-command CLI tool?▼

Yes. Commander.js is a supported tier for building multi-command CLI tools with type-safe interfaces and comprehensive help text. The Skill automatically selects the right complexity level and generates complete implementations with error handling and configuration management tailored to your command structure.

What's the best way to create a CLI wrapper for an API?▼

Define your API requirements, and the Skill generates a complete CLI wrapper with typed command definitions, documentation, and error handling. It produces deterministic JSON output and Bun-based runtime configuration, enabling you to expose API functionality as predictable command-line tools with CLI-first governance.

Do I need to write boilerplate code when building TypeScript CLIs?▼

No. The Skill eliminates manual boilerplate by generating complete CLI implementations with built-in type safety, error handling, comprehensive help text, and configuration management. You describe your requirements and receive fully functional, testable command-line tools ready for production use.

How does tier-based CLI generation work?▼

Tier-based generation automatically selects complexity matching your needs: Tier 1 uses simple llcli-style patterns for basic commands, Tier 2 deploys Commander.js for multi-command tools, and Tier 3 references advanced patterns. Each tier includes appropriate documentation, error handling, and configuration scope without unnecessary overhead.

Can CLIs generated this way handle configuration and environment variables?▼

Yes. Generated CLIs support environment-driven configuration with comprehensive environment variable handling, type-safe interfaces, and deterministic JSON output. This enables portable, testable command-line tools that respect system configuration patterns and integrate with standard deployment and runtime environments.
