Stock Backtest Analyst

Security checks for vulnerabilities and agentic risk

Overview

This skill is a focused local stock backtesting helper with no evidence of hidden network access, persistence, credential use, or destructive behavior.

Reasonable to install if you want local CSV-based stock strategy backtesting. Be aware that the broad trigger wording may activate for general return questions, and treat generated backtest results as research rather than financial advice.

A.I.G

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

The manifest description lists trigger examples including "测收益率", which is vague and not clearly limited to stock-strategy backtesting. This broad phrase could collide with ordinary requests about calculating returns in other contexts, causing unintended invocation.
