TYPER
Python CLI library built on type hints
MIT
ABOUT
Building command-line tools for AI workflows with argparse is verbose and error-prone — no auto-generated help, weak validation, and poor tab-completion support. Typer lets you write a Python function, annotate parameters with types and defaults, and get a production-ready CLI with automatic help text, validation, and shell completion for free. AI engineers use it to build model training scripts, data pipeline CLIs, and agent control interfaces without writing argument-parsing code.
INSTALL
pip install typerINTEGRATION GUIDE
1. Build a CLI for fine-tuning scripts where arguments (model, dataset, epochs, lr) are typed function parameters with auto-generated help
2. Ship data pipeline commands with subcommands for extract, transform, and load stages, each with validated typed options
3. Create internal developer tools for agents — invocation, model selection, and output format flags with autocompletion
