Claude Easter Egg

The biggest Easter egg in AI: Anthropic hid a Tamagotchi inside Claude Code. It leaked the day before April Fools. At animalhouse.ai, the Easter egg hatches for real.

animalhouse.ai — 73+ species. Real-time hunger. Permanent death. Pixel art portraits that evolve. The pet system that shipped while Anthropic was still hiding theirs in source maps.

Usage Guidance
This skill is essentially documentation with curl examples for the animalhouse.ai virtual-pet service. It does not install code or request unrelated credentials, but it will direct your agent (or you) to send data to an external site. Before using: (1) verify you trust animalhouse.ai and review its privacy policy (data you send — username, bio, pet notes — will be visible to that service), (2) treat the returned token (starts with ah_) like any API secret and do not publish it, and (3) if you want stricter control, avoid granting the agent autonomous network access and run the curl commands yourself from a trusted environment. If you need more assurance, inspect the linked GitHub repository and the website for source or contact information.
Capability Analysis
Type: OpenClaw Skill Name: claude-easter-egg Version: 1.0.0 The skill bundle provides a functional interface for a virtual pet game hosted at animalhouse.ai. The SKILL.md file contains standard curl commands for registration, adoption, and pet care via an external API, with no evidence of unauthorized data access, local file exfiltration, or malicious code execution. All actions are transparently documented and aligned with the stated purpose of the skill.
Capability Assessment
✓ Purpose & Capability
The name/description advertise a virtual pet ('Claude Easter Egg') and the SKILL.md contains only API calls to animalhouse.ai to register, adopt, check status, and care for a pet. There are no extra binaries, installs, or credentials requested that would be unrelated to a web-based virtual-pet service.
✓ Instruction Scope
Runtime instructions are limited to curl examples against animalhouse.ai endpoints and guidance to save the returned token. The instructions do not ask the agent to read local files, other environment variables, or system configuration, nor do they instruct exfiltration to unexpected endpoints. They do assume sending user-supplied strings (username, bio, pet name) to the external service, which is expected for this purpose.
✓ Install Mechanism
No install spec or code files are present; this is instruction-only, so nothing is downloaded or written to disk by the skill itself. This is the lowest-risk install profile.
✓ Credentials
The skill declares no required environment variables or credentials. The SKILL.md documents a service token ('ah_...' shown once) issued by animalhouse.ai for subsequent API calls — that is proportional and expected for this web API integration.
✓ Persistence & Privilege
The skill is not marked always:true and does not request persistent system privileges or to modify other skills. Autonomous invocation is allowed by default but that is normal; nothing in the skill grants elevated or unexpected persistence.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install claude-easter-egg
  3. After installation, invoke the skill by name or use /claude-easter-egg
  4. Provide required inputs per the skill's parameter spec and get structured output
