龙虾的小家园 — Desktop Pet

Deploy a pixel-art desktop pet (桌面宠物) with four explorable scenes, care mechanics, and walk animations. Use when user asks to create a desktop pet, virtual p...

Security Scan

The package is plausibly a desktop-pet app, but the provided script performs runtime network downloads (from a raw GitHub URL), creates files under the user's home directory, and requires more asset files than the SKILL.md describes — these mismatches and external network access deserve review before install.

Purpose & Capability

Name/description match the included Python Tkinter desktop pet script. However, SKILL.md's asset list is minimal while the script expects many additional character sprites; the SKILL.md instructs manual asset copying but the script will auto-download missing assets at runtime. This is plausibly legitimate but inconsistent.

Instruction Scope

SKILL.md instructs only to install Pillow and run the script and to copy assets locally, and does not mention network activity. The script, however, will attempt to download numerous asset files from raw.githubusercontent.com if assets are missing, and the presence of http.client/urllib/json imports suggests additional web requests (e.g., weather fetching). The skill also writes a save file under ~/.nbw_pet_save.json. The runtime will therefore access the network and the user's home directory despite SKILL.md implying a local-only run.

Install Mechanism

There is no package install spec (instruction-only), but runtime auto-downloads assets from https://raw.githubusercontent.com/... which is a GitHub raw URL (a known host). Downloading assets at runtime is a supply-chain risk (content can change upstream) and is not sign‑verified, though the host itself is a common code host.

Credentials

The skill requests no environment variables or credentials (ok). It does create an assets directory next to the script and writes a JSON save file to the user's home directory (~/.nbw_pet_save.json), which is proportionate for a desktop app but should be explicitly documented in SKILL.md (it is not).

Persistence & Privilege

The skill is not marked always:true and cannot modify other skills. Its persistence is limited to writing an assets folder (next to the script) and a single save file in the user's home directory — normal for a desktop application.

What to consider before installing

This skill is likely what it claims (a Tkinter desktop pet) but it downloads many asset files from a GitHub raw URL at first run and writes a save file to ~/.nbw_pet_save.json. Before installing or running: (1) inspect scripts/desktop_pet.py fully for any unexpected network calls or data uploads; (2) consider running it in a sandbox or VM; (3) if you prefer offline use, pre-populate the assets/ directory with trusted files to prevent runtime downloads; (4) verify the GitHub repo and asset URLs manually if you plan to allow downloads. If you are uncomfortable with automatic network downloads or files written to your home directory, do not run it.

Desktop Pet — 南波万の小家园

A pixel-art desktop pet built with Python + Tkinter. Features a mini floating character on the desktop and a full home-garden mode with four explorable scenes.

Features

• Mini mode: Transparent floating pixel character with walk animation (128px, white oval background)
• Garden mode: 850×560 window with four scenes connected by doorways
  • 🏠 Indoor (1F) — cozy room with furniture
  • 🪜 Upstairs (2F) — mirrored warm-tone layout
  • 🌿 Outdoor — front yard with fence
  • 🌳 Forest — large woodland area
• Care system: Hunger / Mood / Cleanliness / Health with decay and recovery
• Controls: Arrow keys or WASD to walk, E to interact with doorways, T for debug mode
• Right-click menu: Feed 🍔 / Bathe 🛁 / Play 🎮 / Medicine 💊

Deployment

1. Copy scripts/desktop_pet.py to target directory
2. Copy all files from assets/ into an assets/ subdirectory next to desktop_pet.py
3. Run:

cd <target-dir>
pip install Pillow
TK_SILENCE_DEPRECATION=1 python3 desktop_pet.py

File structure after deployment

target-dir/
├── desktop_pet.py
└── assets/
    ├── room_bg.png        # Indoor scene (1F)
    ├── upstairs_bg.png    # Upstairs scene (2F, mirrored + warm)
    ├── exterior_bg.png    # Outdoor scene
    ├── forest_bg.png      # Forest scene
    ├── walk_right.gif     # Character walk right (8 frames, 32×32)
    └── walk_left.gif      # Character walk left (8 frames, 32×32)

macOS notes

• Uses overrideredirect(True) + systemTransparent for floating mini window
• PhotoImage doesn't render on transparent canvas → white oval workaround
• Set TK_SILENCE_DEPRECATION=1 to suppress Tk warnings

Scene transitions

From	Trigger	To
Indoor 1F	Walk to staircase (top-left) + E	Upstairs 2F
Indoor 1F	Walk to carpet (bottom-right) + E	Outdoor
Upstairs 2F	Walk to staircase (top-right) + E	Indoor 1F
Outdoor	Walk to left edge + E	Forest
Outdoor	Walk to door + E	Indoor 1F
Forest	Walk to right edge + E	Outdoor

Customization

• Backgrounds: Replace PNG files in assets/ (850×526px recommended)
• Character: Replace GIF files (32×32 per frame, 8 frames)
• Care decay rate: Search frame%600 in code (higher = slower decay)
• Collision walls: Edit _INDOOR_WALLS / _OUTDOOR_WALLS arrays
• Window sizes: W_M, H_M for mini mode, W_G, H_G for garden mode
