Security checks for vulnerabilities and agentic risk

Overview

This is a plain US stock analysis prompt skill with no executable code, persistence, credential handling, or hidden data access.

Installers should understand that this skill can produce investment research and optional trade-plan structure, but it explicitly requires sourcing, risk framing, no fabricated data, and a non-advice disclaimer. Users should still verify market data and make their own financial decisions.

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

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 96% confidence
Finding: The markdown declares language: en-US as a hard setting, while the rest of the skill does not provide any opt-in or alternative locale handling. Under the policy, fixed language or locale constraints should either be optional for the user or clearly justified as region-specific beyond market coverage alone.
