# Petsonality

Petsonality puts an MBTI-based ASCII pet in the terminal. It reacts to coding events and gives you /pet commands for interaction.

## What it does

Petsonality runs a small ASCII companion in the terminal and gives it a personality based on MBTI. It reacts when code fails, may celebrate passing tests or successful commits, and speaks up after a quiet stretch. The `/pet` commands let you view the pet, browse the animals, rename it, or mute its reactions.

The MCP server is launched through `npx` and can be connected to Claude Code, Codex, Cursor, GitHub Copilot, and the other listed clients. Its installer includes the `/pet` skill, hooks, and status-line assets. It also updates `~/.claude.json` and `~/.claude/settings.json`; a source install requires Bun.

The animated pet needs a terminal status line. It will not render in the Claude Code desktop app or web client, although MCP output such as `/pet show` still works from any client.

## Requirements
- Needs: Node.js (commands run via npx)
