desktop-pet

name: desktop-pet description: One-command animated desktop pet generator. Converts any image into an interactive desktop pet with multiple animations (idle, walk, jump, happy, pet, sleep, etc.) and automatic preview. Use when user wants to create a desktop pet, animated character, screen companion, or mentions "desktop pet", "桌宠", "screen pet", "create pet from image", or uploads an image asking for a pet/companion. Generates web, extension, and desktop versions with drag interactions, click animations, and visual effects.

Desktop Pet Generator

Convert any image into an animated desktop pet with one command. Automatically generates sprite animations, interactive behaviors, and preview.

Quick Start

Minimal usage - just provide an image:

python3 scripts/create_pet.py /path/to/image.png

This automatically:

• Analyzes the image
• Generates appropriate pet name
• Creates 7 animations (standard preset)
• Builds web, extension, and desktop versions
• Starts preview server
• Returns preview URL

Usage Patterns

Pattern 1: Minimal (Image Only)

User provides image, everything else auto-generated:

python3 scripts/create_pet.py cat.png

Pattern 2: Custom Name

python3 scripts/create_pet.py dog.png --name "小狗"

Pattern 3: Custom Animations

python3 scripts/create_pet.py bear.png --name "Bear" --animations complete

Pattern 4: Full Control

python3 scripts/create_pet.py image.png --name "My Pet" --animations core --output ./my-pet

Animation Presets

• core: 3 animations (idle, walk, jump) - Fast generation
• standard: 7 animations (adds happy, pet, sleep, eat) - RECOMMENDED
• complete: 10 animations (adds attack, hurt, death) - Maximum variety

For detailed animation information, see references/animations.md.

Interaction Features

Generated pets support:

• Drag: Triggers walk animation
• Click: Jump animation
• Double-click: Happy animation
• Long-press (2s): Pet animation with floating hearts
• Right-click: Context menu with all animations
• Idle (5s): Returns to idle breathing
• Idle (60s): Sleep animation with Z symbols
• Keyboard (1-9, Space): Desktop version only

Workflow

When user requests a desktop pet:

1. Identify the image path from user message or attachments
2. Extract any custom name from user request
3. Determine animation preset (default: standard)
4. Run scripts/create_pet.py with appropriate parameters
5. Report the preview URL to user
6. Explain key interactions (drag, click, long-press, right-click)

Automatic Packaging

The script automatically packages ready-to-install versions:

Browser Extension

• Automatically creates extension.zip file
• Ready to install: Load unpacked in Chrome/Firefox
• Contains all required files (manifest.json, content.js, sprites)
• No manual zipping required

Desktop App (Electron)

• Automatically runs npm install and electron-builder if npm is available
• Generates platform-specific executables in desktop-app/dist/:
  • Windows: .exe installer
  • macOS: .dmg installer
  • Linux: .AppImage executable
• Falls back to source files if npm is not available
• Build time: ~2-3 minutes (one-time per pet)

Implementation Notes

• The script automatically starts an HTTP server on port 8080
• Port export is handled automatically if /app/export-port.sh exists
• Preview URL is returned in the script output
• All three versions (web, extension, desktop) are generated simultaneously
• Generation time: ~5 seconds for standard preset (plus packaging time for desktop if npm available)

Dependencies

Requires the desktop-pet-generator skill to be installed alongside this skill. The underlying pet_generator.py is located at:

~/.claude/skills/desktop-pet-generator/scripts/pet_generator.py
