## What it is
A collection of programmable completion functions for the Bash shell, providing smart tab-completion of options and arguments for many commands. It also includes helper functions and facilities for writing and auto-loading new completion recipes.

## Use cases
- enable tab completion for command options and arguments in bash
- write custom bash completion functions for my own CLI tool
- auto-load completion scripts on demand
- improve bash filename completion with command-aware suggestions

## When to choose
- you use Bash and want rich tab completion for common commands
- you are developing a CLI tool and want to ship completions for it
- you need helper APIs to author new completion recipes

## When to avoid
- you use zsh, fish, or another shell with its own completion system
- you need completions for a shell other than Bash

## Facets
- artifact type: library
- maturity: stable
- function: cli, developer-tools
- domain: developer-tools
- platform: cli, cross-platform
