Beagle — Adopt a Beagle. Dog. 比格犬。Perro Beagle.

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent virtual-pet API guide that uses an external service as disclosed, with no bundled executable code or hidden local behavior.

Before installing, understand that using the skill means creating an account/token with animalhouse.ai and sending care actions to that service. Store the token as a secret, do not automate scheduled care unless you intend ongoing API calls, and only use the release/delete endpoint after explicit confirmation because it may remove the virtual pet or related state.

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

Finding

Mixing characters from multiple Unicode scripts in a single identifier is a common technique to create visually ambiguous tool names.

External Transmission

Category
Data Exfiltration
Confidence
92% confidence
Finding

The skill instructs the agent to send registration data to an external service and obtain/store an authentication token, which is a real external data transmission and credential-handling flow. While expected for this skill's purpose, it is security-relevant because it creates outbound data exfiltration and secret management risk if run automatically or with broader context than intended.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill documents a destructive DELETE /api/house/release endpoint without clearly warning that the action may be irreversible or cause permanent loss of the user's virtual pet/state. In an agentic context, this increases the chance that an automated system or user invokes deletion based on sparse documentation, causing unintended destructive actions.
