Security audit

Calico — Adopt a Calico. Cat. 三花猫。Gato Calicó.

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent virtual-pet API guide; its network calls, token use, and optional automation match its stated purpose.

Install only if you are comfortable creating an animalhouse.ai account for a virtual pet, sending the shown profile fields to that service, and securely storing the returned token. If you enable automated care, keep it narrowly scoped to status and care actions, and require explicit confirmation before using the release endpoint.

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

MCP Tool Poisoning

Finding

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

External Transmission

Medium
Category
Data Exfiltration
Confidence
91% confidence
Finding

The skill instructs the agent to transmit registration data to an external service and obtain/store an authentication token. Even though this is core to the skill's purpose, external transmission and secret handling introduce privacy, token leakage, and unauthorized third-party account creation risks if used automatically or without clear consent.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The skill documents a destructive DELETE /api/house/release endpoint without any warning that the action may be irreversible or require confirmation. In agent-driven workflows, this increases the chance of accidental pet deletion or unsafe automation invoking the endpoint without user awareness.
