What problem does it solve?

It helps you design and implement reliable command-line tools that behave predictably, present clear help, and handle invalid inputs safely.

Core Features & Use Cases

  • POSIX-compliant CLI design: Uses standard UNIX-style argument conventions and help formatting.
  • Strict validation and argument parsing: Supports required/optional args, defaults, and mutually exclusive options with clear error behavior.
  • Consistent exit codes and stderr messaging: Produces user-friendly failures with appropriate exit statuses.
  • Testing-ready deliverables: Ensures argument parsing and error handling paths are covered with unit tests.

Quick Start

Ask the AI: "Design a small POSIX-friendly CLI in Python with argparse that validates required arguments, provides standard UNIX help output, uses stderr for errors, and returns exit code 2 for argument mistakes."
