## What it is
VirtualFish is a Python virtual environment manager for the Fish shell, offering a `vf` command and a plugin system. It emulates virtualenvwrapper features like auto-activation, project management, and environment variable automation.

## Use cases
- manage python virtualenvs in fish shell
- auto-activate virtualenv when cd into project
- virtualenvwrapper alternative for fish
- create and switch python environments from terminal
- show current virtualenv in fish prompt

## When to choose
- you use the Fish shell and want virtualenvwrapper-like workflow
- you want plugin-based virtualenv management with auto-activation

## When to avoid
- you use bash or zsh instead of fish
- you prefer built-in venv or tools like pyenv/poetry
