Security audit

English Polish

Security checks for vulnerabilities and agentic risk

Overview

This is a plain English-writing polishing skill with no code, permissions, persistence, or hidden behavior identified.

Install this if you want an assistant to polish English writing and explain corrections. It may standardize phrasing toward native-sounding English, so review edits when preserving a distinctive voice or non-English explanation style matters.

A.I.G

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

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The title and description position the skill exclusively around improving English writing, and the instructions assume English output throughout. This imposes a language constraint without any user opt-in or explanation that the skill is intentionally limited to English, which matches the policy concern for forced language/locale behavior.
Content: No source excerpt is available for this finding.
