This Skill provides a standardized framework for building command-line interfaces that are user-friendly for humans, stable for shell scripts, and reliable for CI/CD automation.
Use the py-cli skill to generate a new command-line tool structure using Typer that includes proper argument parsing and error handling.
High-intent search queries and answers about installing and using this skill.
To build a robust Python CLI tool, define clear command contracts, standardize exit codes, and implement machine-readable output formats to ensure predictable execution in CI/CD pipelines.
Choosing between argparse, Click, and Typer depends on your project complexity and requirements, balancing built-in standard library support against advanced features for structured argument parsing and error handling.
Structure stdout and stderr streams by separating machine-readable output from error messages, defining strict command contracts and exit code standards to ensure stable behavior for shell script automation.
Yes, the framework supports non-interactive execution in automated environments by implementing patterns for machine-readable JSON output and atomic file operations tailored for containerized tasks.
Defining command contracts and exit code standards for terminal applications ensures high-quality CLI UX, predictable behavior across interactive shells, and reliable error handling for shell scripts.
