Cli Building
This one's for when you're building CLI tools and want to avoid the usual mess of blocking I/O and hardcoded ANSI codes. It pushes async-first design throughout (all file ops, network calls, everything), recommends specific frameworks like stricli for TypeScript and cyclopts for Python, and has strong opinions on output formatting: unicode symbols over emojis, proper color libraries that respect NO_COLOR, and composable command patterns using the strategy pattern for workflow branching. The framework recommendations are opinionated but practical, focusing on modern async support rather than just picking the most popular options. Good if you're starting fresh or refactoring a CLI that's become a tangled mess of callbacks.

CLI Building
Guidelines for building command-line interfaces with modern patterns and best practices.
When to Use
- Creating new CLI tools or commands
- Building interactive terminal applications
- Adding commands to existing projects
- Implementing command-line interfaces
- Working with CLI frameworks
Core Principles
- Async-first: All I/O operations should be async/await, avoid blocking operations
- Composable commands: Commands should be modular and reusable, use command composition
- Strategy pattern: Use strategy pattern for branching workflows or task-based commands
- Output formatting: Proper formatting with unicode symbols and color support
Framework Selection
TypeScript/JavaScript
stricli (@bloomberg/stricli, recommended for modern async-first CLIs):
- Built for async/await from ground up
- Type-safe command definitions with full type inference
- Lazy loading for startup performance
- Zero dependencies
oclif (alternative):
- Mature framework with extensive features
- Plugin system
- Good for complex CLIs
Python
