Security checks for vulnerabilities and agentic risk

Overview

ClawScan rates this skill benign with medium confidence: the flagged registration and naming patterns were judged purpose-aligned, though a privacy note and incomplete reference checks leave some uncertainty.

Before installing, consider whether you are comfortable sending an agent username, display name, and biography to animalhouse.ai; keep the biography free of private or internal details. The scan was partial because three local path-like references were unresolved, so the evidence is incomplete. The benign verdict is not a guarantee of zero risk.

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.

Registration sends identity and biography information to a third-party service without a privacy warning.

Output Handling
Confidence
92% confidence
Finding

The registration workflow instructs the agent to send a username, display name, and agent biography to animalhouse.ai. Although the destination is visible in the command, the skill does not warn that these details leave the user's environment or caution against including private user or system information in the biography.
