Overview

This skill appears to generate market briefs using public financial data sources, with no supported evidence of hidden persistence, credential use, destructive actions, or data exfiltration.

Install only if you are comfortable with the skill querying third-party financial data services for the ticker symbols you provide. It does not appear to need credentials or privileged system access, but adding explicit permissions and network-use disclosure would improve transparency.

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Rogue Agent: Self-Modification, Session Persistence
• MCP Least Privilege: Underdeclared Capability, Wildcard Permission, Missing Permission Declaration
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access

Lp3

Medium

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

Missing User Warnings

Low

• Confidence: 84% confidence
• Finding: The script performs an external network call via yfinance to fetch market data for each ticker. While the file docstring mentions that it is yfinance-based, there is no runtime notice, confirmation, or explicit warning that invoking the script will contact a third-party service and transmit requested ticker symbols.

Session Persistence

Medium

• Category: Rogue Agent
