Security audit

Modular Market Brief

Security checks across malware telemetry and agentic risk

Overview

This skill appears to be a straightforward market-brief helper that fetches public financial data and does not show hidden persistence, credential access, destructive behavior, or unrelated data collection.

Install only if you are comfortable with the skill using third-party financial data services for tickers and market screens you request. It does not appear to require credentials or privileged system access, but clearer permission metadata and a domain/network disclosure would improve transparency.

Finding
The skill explicitly instructs use of external data sources such as yfinance, exchange sites, and finance portals, which implies network access despite no declared permissions. Undeclared network capability weakens transparency and policy enforcement, and could enable unexpected outbound requests or data exfiltration if the skill is later extended with executable helpers.
