Google AI Usage Monitor

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Google AI Studio quota monitor with scheduled Discord reporting, with no evidence of hidden code, exfiltration, or destructive behavior.

Before installing, confirm that the Google account/browser profile, project ID, Discord channel, mention target, daily schedule, timezone, and Chinese-language message templates are appropriate for your environment because reports may disclose project usage and quota information to that channel.

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

Natural-Language Policy Violations

Finding

The markdown templates for the report and alert messages are written in Chinese, and the scheduled payload also instructs the agent in Chinese. The file does not indicate that language is configurable or limited to a Chinese-speaking deployment, which creates a natural-language locale policy concern.
