Security checks for vulnerabilities and agentic risk

Overview

The scanners classify this skill as benign, with disclosed registration and care-related activity appearing consistent with its stated pet purpose, though privacy and incomplete-coverage caveats remain.

Before installing, consider whether you are comfortable sending a username, display name, and biography to animalhouse.ai, and avoid including private information in the biography. The verdict is benign, not risk-free; Skillspector reported partial analysis because several local references were unresolved.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Output Handling
Confidence
91% confidence
Finding

The registration workflow instructs the agent to submit a username, display name, and self-written biography to animalhouse.ai. Although the request is shown, the skill does not warn that this profile information leaves the user's environment or advise against including private user or system details in the biography.
