Usage Guidance
What to consider before installing:
- Verify the service: check the animalhouse.ai website and the referenced GitHub repository. Prefer installing only after confirming the project and maintainers are legitimate.
- Inspect SKILL.md for hidden/control characters and remove them; the scanner found unicode-control-chars which can be used to alter prompts or hide content.
- Treat the 'your_token' (starts with ah_) as a bearer token: create a throwaway/test account first, do not use high-privilege or personal credentials, and do not paste other secrets into fields requested by the skill.
- The skill is instruction-only (no install), so host-level risk is low, but the agent will make network calls to animalhouse.ai; ensure your environment allows that and that you trust the endpoint's TLS certificate.
- If you plan to use this long-term, review the GitHub source code referenced in SKILL.md before trusting it with real data, and confirm privacy/terms — the README's 'leaked' claim may indicate questionable provenance or legal issues.
- If you want higher assurance, ask the publisher for the canonical API docs or an official SDK, and test with a sandbox account. Remove the skill if it asks for unrelated credentials or system file access.
Confidence notes: assessment is medium because the skill is internally coherent and low-privilege, but the prompt-injection signal and the 'leaked' provenance claim warrant caution and manual review of the SKILL.md and associated website/repo before trusting tokens or enabling autonomous invocation.
Capability Analysis
Type: OpenClaw Skill
Name: anthropic-buddy
Version: 1.0.0
The skill bundle provides instructions and API documentation for interacting with a virtual pet service hosted at animalhouse.ai. It contains standard curl commands for registration, adoption, and pet maintenance (feeding, playing) using a token-based authentication system. No evidence of data exfiltration, malicious execution, or harmful prompt injection was found; the content is consistent with a promotional or game-related integration.
Capability Assessment
Purpose & Capability
Name/description match the provided runtime instructions: SKILL.md is an instruction-only guide for animalhouse.ai endpoints (register, adopt, status, care). No unrelated binaries, env vars, or config paths are requested.
Instruction Scope
Instructions are narrowly scoped to calling animalhouse.ai HTTP endpoints and storing a bearer token shown once. They do not request system files or unrelated credentials. However: the doc does not declare how the agent should store/use the token securely and contains language claiming a 'leak' which may indicate questionable provenance or social-engineering intent.
Install Mechanism
No install spec and no code files — instruction-only skill. This minimizes disk writes and install-time risk.
Credentials
The skill declares no required environment variables or credentials; it expects a bearer token created by the API flow. That's proportionate, but the SKILL.md instructs the user to 'Save your_token' without guidance for secure storage or rotation.
Persistence & Privilege
always is false and the skill is user-invocable. It does not request persistent system presence or modify other skill configs.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install anthropic-buddy - After installation, invoke the skill by name or use
/anthropic-buddy - Provide required inputs per the skill's parameter spec and get structured output
