Stock Backtest Analyst Clean

Security checks for vulnerabilities and agentic risk

Overview

This skill is a local stock-strategy backtesting helper that reads user-provided CSV price data and reports metrics without hidden network, persistence, or destructive behavior.

Install only if you want a local CSV-based stock backtesting helper. Treat results as research, not financial advice, and verify the CSV path and cost assumptions before running backtests.

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

MCP Least Privilege
Confidence
70% confidence
Finding
Without declared permissions the skill's intent is opaque and cannot be validated.

Vague Triggers

Medium
Confidence
89% confidence
Finding
The manifest description lists trigger examples including "测收益率", which is generic enough to overlap with ordinary requests about returns rather than specifically invoking a stock-strategy backtesting skill. Because the trigger list is presented without explicit scope limits or negative examples, it may cause unintended activation for loosely related finance questions.
