Security checks for vulnerabilities and agentic risk

Overview

This is a public-company research prompt with no executable code, persistence, credentials, or account-changing behavior.

Install only if you want an agent to generate informational public-stock research. Treat its output as research support, not financial advice, and verify current market data and valuation assumptions before relying on them.

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

Vague Triggers

Medium
Confidence
94% confidence
Finding
The trigger phrase "Is [company] a good buy right now?" is broad enough to capture ordinary investment-seeking conversation and immediately route the user into a prescriptive finance workflow. In a financial-analysis skill, that increases the chance of unsolicited or overly assertive investment guidance, especially when paired with mandatory real-time data gathering and a fixed output structure that may discourage appropriate narrowing or safety checks.

Natural-Language Policy Violations

Low
Confidence
88% confidence
Finding
Line L13 instructs the skill to "support English + major other languages if possible," which imposes a language behavior without specifying that the user should choose or opt in to a language/locale. This can violate language/locale policy expectations when the user has not requested multilingual output.
