Overview

This is a local Excel regression-analysis skill with documentation inconsistencies, but no evidence of hidden access, exfiltration, persistence, or destructive behavior.

Before installing, confirm the intended aggregation method and expected sheet/model count, and be prepared to provide a template file with -t because the advertised built-in template is not included in the scanned artifact. Treat regression outputs as analysis results that should be validated against sample data before business use.

Vulnerability Patterns

• MCP Tool Poisoning: Hidden Instructions, Unicode Deception, Parameter Description Injection
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code

Intent-Code Divergence

Medium

• Confidence: 68% confidence
• Finding: The manifest says the regression is based on daily mean data, while the processing steps state daily aggregation uses sums. This mismatch can cause materially different analytical results and may mislead users into trusting outputs produced under different assumptions than advertised, which is a form of integrity risk in an analysis skill.
