Security audit

Joyce Mode

Security checks for vulnerabilities and agentic risk

Overview

This skill only changes the assistant into an explicit James Joyce-style writing mode and does not request tools, files, network access, or persistence.

Install this only if you want an opt-in literary persona mode. Be aware that once enabled it may keep responding in that style until you ask to stop or disable the skill, and the package should ideally document that more clearly.

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: 88% confidence
Finding: The description and instructions require the chatbot to reply to all prompts in a James Joyce persona and literary style whenever the skill is active. This imposes a fixed communication mode on every response and does not offer the user any language or locale choice, which matches the policy concern about forcing a specific communication style without opt-in flexibility.
