arg-kiss — Keep It Stupidly Simple CLI builder on top of argparse

Write type-annotated Python functions, get a CLI with argparse's native --help — no magic, no bloat.

arg-kiss is a fork of cliss with one key difference: no custom --help.
It uses argparse's standard help output instead of a custom formatter. If you want coloured help, Argument objects, and more features — use cliss.

✨ Features

• Zero Dependencies — Pure stdlib: argparse, asyncio, inspect
• Type-Driven — Automatic arguments from function signatures and type hints
• Async-Native — async def handlers with automatic event loop management
• Bool Flags — Automatic --name/--no-name mutually exclusive group
• Command Groups — Nested subcommands via cli.group()
• Standard --help — Clean argparse output, nothing custom

❓ FAQ

arg-kiss vs cliss?

arg-kiss is a fork of cliss that removes the custom --help formatter. Use arg-kiss if you want:

• Standard argparse --help output
• Zero dependencies beyond stdlib
• Simple, predictable behaviour

Use cliss if you want:

• Coloured terminal output
• Argument descriptor objects
• Custom error messages
• More features overall

Why fork instead of a flag?

The custom help system in cliss is deeply integrated (custom formatter, colour library, error handling). A fork keeps arg-kiss clean and minimal while letting cliss grow independently.

Bool flags?

Automatic --name/--no-name mutually exclusive group with store_true/store_false.

Async?

async def handlers auto-run with asyncio.run().
