Can I test my CLI tools with this skill?

Yes, it provides specific patterns for unit testing logic with Bun:test and integration testing real CLI invocations via the shell.

Does this skill require external libraries like Commander or Yargs?

No, it advocates for manual parsing to keep tools lightweight and dependency-free, following the SideQuest marketplace standard for speed and simplicity.

Why should I provide both Markdown and JSON output?

Markdown is optimized for human readability and rich terminal display, while JSON allows your CLI to be piped into other tools and integrated into automated scripts.

How does this handle complex argument formats?

The skill includes logic to parse three common flag formats: spaced values (--flag value), equals syntax (--flag=value), and boolean flags (--flag).

What is the benefit of the dry-run pattern?

The dry-run pattern allows users to preview changes before they are applied, which is a critical safety feature for tools that modify the filesystem or git state.

開発者ツール

Builds production-grade CLI tools using Bun with patterns for argument parsing, dual-format output, and robust error handling.

概要

This skill provides a comprehensive framework for developing high-quality command-line interfaces with Bun, emphasizing dependency-light architectures and professional user experiences. It guides developers through implementing standardized argument parsing for multiple flag formats, supporting dual output modes (Markdown for humans and JSON for machines), and managing complex command structures with subcommands. Designed for the SideQuest marketplace, it focuses on creating tools that are easy to maintain, test, and use, featuring advanced patterns like dry-run modes and Git integration.
