Security audit

NiuYao Stock Picker

Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed A-share stock-screening report generator with no evidence of hidden credential access, destructive behavior, or data exfiltration.

Install only if you want an informational A-share screening tool. Treat outputs as market analysis rather than investment advice, install AkShare and pandas in an isolated environment, and confirm or disable any separate scheduled push configuration before relying on recurring reports.

Vague Triggers

Medium
Confidence
90% confidence
Finding
The example trigger phrase is broad enough to match ordinary requests for stock review or market analysis, which can cause the skill to activate outside its intended scope. In an agent environment, overly permissive activation increases the chance of unintended tool use, data fetching, or financially sensitive recommendations being surfaced when the user did not explicitly request this specific skill.

Missing User Warnings

Medium
Confidence
86% confidence
Finding
The skill states that a daily 15:05 automated run and push notification are already configured, but it does not provide user-facing warning, consent, disablement guidance, or scope of what will be sent. Automated execution and outbound reporting can surprise users, leak trading-related outputs to unintended recipients, or create unauthorized recurring actions in an agent environment.
