Security checks for vulnerabilities and agentic risk
Overview
The skill appears to do the advertised trading-signal analysis, but its install instructions use an overbroad system Python package install method.
Install only in an isolated virtual environment, avoid --break-system-packages, and understand that ticker symbols you analyze will be sent to the market-data provider used by yfinance. The code does not show hidden credential access or destructive behavior.
Vulnerability Patterns
- Insecure DependenciesIntroduces malicious components through unsafe dependency sources
- 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

Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 96% confidence
- Finding
The manifest description and the entire user-facing documentation are written exclusively in Chinese, and the sample output is also fixed to Chinese. There is no indication that users can choose another language or that the Chinese-only behavior is a justified locale-specific constraint, which matches the language/locale policy violation criteria.

Natural-Language Policy Violations
Medium

- Not specified by scanner
- Confidence
- 95% confidence
- Finding
Natural-language strings throughout the file, including the module description and all console output, are fixed in Chinese. The file does not provide user opt-in, a configurable locale, or a documented justification that this is intended only for a Chinese-speaking or region-specific environment.

Missing User Warnings
Low
- Category
- Not specified by scanner
- Confidence
- 86% confidence
- Finding
This Python code fetches market data from yfinance by creating a remote ticker object and requesting history data. Although errors are printed, there is no explicit disclosure that running the script will contact an external service and transmit the requested symbol, which qualifies as a network operation lacking a user warning in this file.
