## What it is
A Python library that provides easy, extensible bash/zsh tab completion for command line applications built with argparse. It hooks into the shell's completion framework to dynamically suggest arguments, options, and values as the user types.

## Use cases
- add tab completion to my python cli tool
- autocomplete argparse options in bash
- dynamic completion of argument values from network resources
- enable zsh completion for python scripts
- globally activate completion for all python argparse apps

## When to choose
- your CLI is written in Python and uses argparse
- you want bash or zsh tab completion with minimal code changes
- you need dynamic completers for files, directories, or custom values

## When to avoid
- your CLI does not use argparse
- you need first-class support for shells other than bash/zsh
- your program has heavy side effects before parser construction

## Facets
- artifact type: library
- maturity: stable
- function: cli, developer-tools
- domain: developer-tools
- platform: python, cli
- tags: tab-completion, argparse, bash-completion, zsh-completion, shell-completion, command-line, linux, macos
