cli-builder

Build TypeScript CLIs with Bun by setting up argument parsing for flags and positional arguments, organizing commands into a subcommand registry pattern, and formatting output as JSON or colorized text. Bun's runtime executes your CLI scripts directly without compilation overhead.

Structure multi-command tools using subcommand patterns that register each command with consistent argument parsing and output formatting. This Skill demonstrates registry-based organization suitable for complex tooling and automation tasks.

Yes. Bun CLIs support a plugin-friendly extension model and can be distributed as shell-executable scripts. The Skill covers patterns for building distributable command-line tools with consistent behavior across environments.

Parse arguments and flags by extracting values from the arguments array, validating flag patterns, and mapping them to command handlers. This Skill shows argument parsing techniques integrated with subcommand dispatch.

Bun provides built-in capabilities for JSON serialization and string formatting. This Skill demonstrates how to implement both JSON and colorized output modes without external dependencies.

Bun CLIs can perform file-system operations and execute shell commands natively. This Skill covers file-system helpers and shell execution utilities designed for automation tasks and project-specific commands.
