## What it is
Carapace-bin is a multi-shell argument completion binary written in Go that provides tab completion for hundreds of CLI commands. It works across POSIX and non-POSIX shells including Bash, Zsh, Fish, Nushell, PowerShell, Elvish, Xonsh, and more.

## Use cases
- add tab completion for cli commands in zsh
- shell autocompletion for hundreds of commands
- unified completion across bash fish and nushell
- complete git docker kubectl arguments in powershell
- write custom completion specs for my own cli
- replace per-shell completion scripts with one binary

## When to choose
- you use multiple shells and want consistent completions
- you want completions for many commands without installing per-shell scripts
- you need to define custom completions via specs or macros

## When to avoid
- you only need completion for a single shell and its native system suffices
- you need completion for a shell not on the supported list
- you want a library embedded in your own Go program (use carapace core library instead)
