Security checks for vulnerabilities and agentic risk

Overview

The bundled skill performs local text analysis with proportionate file access and no hidden network activity or persistence.

Review results manually: the quickstart processes the brief itself rather than its referenced CSV, and copied samples are not automatically anonymized. Remove customer identifiers before sharing reports. The optional unsigned Windows app is unnecessary for this workflow and requires a separate trust decision; its listed hash does not establish safety.

Vulnerability Patterns

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
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Findings (1)

Skill declares no tool scope ('permissions' or 'allowed-tools') but code capabilities were detected: file_write.

Medium

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