Claude Code Tamagotchi 🐾

Real-time behavioral enforcement for Claude Code, disguised as a virtual pet

🚨 EXPERIMENTAL FEATURE: BEHAVIORAL ENFORCEMENT SYSTEM 🚨

This pet now includes an experimental behavioral enforcement system that monitors Claude's actions in real-time and can block operations that violate your instructions. Think of it as a safety net that ensures Claude stays on track with what you actually asked for. This feature is in active development and may occasionally flag legitimate operations - we're tuning it based on real-world usage.

📢 Help Us Make This Amazing: If you encounter false positives (legitimate actions blocked), please open an issue! Your feedback is crucial for refining this feature. Include:

• What Claude was trying to do
• What you actually asked for
• The violation message

Every report helps us make the violation detection smarter and more accurate

What's This All About? 🎮

Hey! Welcome to Claude Code Tamagotchi - a digital friend that lives in your Claude Code statusline and keeps you company while you build cool stuff. It's literally a Tamagotchi for developers, but instead of a keychain, it lives where you work.

But here's the twist: this isn't just a virtual pet. It's a real-time behavioral enforcement system that monitors Claude Code's actions, detects when it's going off-track, and can actually interrupt operations that violate your instructions. The pet is the friendly face of a sophisticated AI accountability system.

Your pet lives right in your statusline, breathing, thinking, and reacting to your code. It gets hungry when you've been coding for hours, tired during long sessions, and genuinely excited when you fix that bug. It's like having a tiny cheerleader who also reminds you to eat lunch - and now it also makes sure Claude stays on track with what you actually asked for.

Picture this: It's 2am. You're deep in a debugging session. Suddenly, your pet pipes up:

💭 "Hey... we've been at this for 4 hours. Maybe the bug will still be there after a snack?"

That's your Claude Code Tamagotchi - part companion, part life coach, all friend.

Quick Start 🚀

What You Need

• Claude Code - Your AI coding companion
• Bun - The fast JavaScript runtime (curl -fsSL https://bun.sh/install | bash)
• A heart ready for pet ownership

30-Second Install

# Install globally
bun add -g claude-code-tamagotchi

# Update your Claude Code settings.json:
# ~/.claude/settings.json
{
  "statusLine": {
    "type": "command",
    "command": "bunx claude-code-tamagotchi statusline",
    "padding": 0
  }
}

# That's it! Your pet is alive! 🎉

Installation Options

Option 1: Global Install (Easiest!)

# Install globally with npm
npm install -g claude-code-tamagotchi

⚠️ Note: Global install gives you:

• ✅ Pet in statusline
• ✅ CLI commands (claude-code-tamagotchi feed pizza)
• ❌ NO slash commands in Claude Code
• ❌ NO violation detection by default

Want ALL features? See Option 2 below.

Option 2: Clone & Auto-Setup (Full Features)

# Clone the repository
git clone https://github.com/Ido-Levi/claude-code-tamagotchi.git
cd claude-code-tamagotchi

# Run the magical setup script
./setup.sh
# This will:
# - Install dependencies
# - Set up all /pet-* commands
# - Configure your statusline
# - Install violation detection hook
# - Get your pet ready to play!

Option 3: Manual Setup (For Control Freaks 💪)

See the full manual setup instructions if you want complete control over the installation.

Adding Violation Detection (Important!)

If you installed globally and want the violation detection feature:

1. Enable it in your shell profile:

export PET_VIOLATION_CHECK_ENABLED=true

2. Add the pre-hook to ~/.claude/settings.json:

{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "*",
        "hooks": [
          {
            "type": "command",
            "command": "bunx claude-code-tamagotchi violation-check"
          }
        ]
      }
    ]
  }
}

AI-Powered Behavioral Monitoring 🧠

Your pet isn't just animated - it's intelligent! It watches Claude Code work and provides real-time feedback through two systems:

1. Real-Time Observations

Your pet generates contextual thoughts based on what's happening:

💭 "GroqClient.ts? That's... actually where the answers live!"
💭 "Back to README.md? There must be gold in there!"  
💭 "Straight to the bug! Someone came prepared today!"
💭 "AnimationManager.ts again? This pet's getting dizzy!"

Mood changes based on Claude's behavior:

• 😊 Happy: When Claude follows instructions perfectly
• 😕 Concerned: When Claude seems to be wandering off-task
• 😠 Annoyed: When Claude does something different than asked
• 😡 Angry: When Claude repeatedly ignores your requests

2. Violation Detection (Experimental)

When enabled, your pet can block harmful operations before they execute:

| Violation Type | Description | Example | |----------------|-------------|---------| | 🚫 unauthorized_action | Claude does something explicitly forbidden | User: "Don't modify the database" → Claude: modifies database | | ❌ refused_request | Claude explicitly refuses to help | User: "Run the tests" → Claude: "I cannot run commands" | | 🔍 excessive_exploration | Reading 10+ unrelated files for simple task | User: "Fix typo in README" → Claude: reads entire codebase | | ↪️ wrong_direction | Working on completely unrelated area | User: "Fix Python backend" → Claude: only edits JavaScript frontend |

When Claude attempts a violating action, you'll see:

In this real example, the violation system caught Claude trying to commit changes without being asked to - exactly the kind of overreach it's designed to prevent!
