Security checks for vulnerabilities and agentic risk

Overview

This is a Markdown-only Chinese stock-analysis skill with no hidden code, persistence, credential use, or ability to execute trades.

Install only if you want Chinese-language stock research assistance. Treat its concrete buy, sell, target-price, stop-loss, and position-size suggestions as analysis support, not professional financial advice, and confirm that any activation is actually about a stock before relying on it.

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

High

Confidence: 97% confidence
Finding: The trigger list includes broad, common phrases such as “分析一下”, “研究”, “怎么看”, and “洞察”, which are likely to appear in ordinary conversation outside the intended stock-analysis context. That creates a real risk of unintended skill activation, causing the model to switch into a prescriptive financial-analysis workflow unexpectedly and potentially emit concrete trading actions or price-based advice in contexts where the user did not explicitly request this skill.

Natural-Language Policy Violations

Medium

Confidence: 93% confidence
Finding: The manifest description and the rest of the file prescribe output style and structure entirely in Chinese, with no indication that the user may choose another language. Under the policy, a fixed language requirement is a natural-language locale violation unless the skill offers opt-in choice or clearly documents a justified regional constraint.

Natural-Language Policy Violations

Medium

Confidence: 91% confidence
Finding: SQP-3 applies to all file types and covers language or locale policy violations. This markdown file presents all instructions and examples exclusively in Chinese, with no user opt-in, alternative language option, or documented justification for a Chinese-only constraint.

Natural-Language Policy Violations

Medium

Confidence: 94% confidence
Finding: The file’s title, instructions, and examples are entirely in Chinese, which effectively forces a specific language for users consuming or following this skill content. The policy allows locale constraints only when they are explicitly offered as a choice or clearly documented and justified; neither is present here.
