Security audit

Visual Concept

Security checks for vulnerabilities and agentic risk

Overview

This skill is a standalone creative prompt for turning conversation context into visual direction, with no executable code or hidden data access.

Before installing, understand that the skill may synthesize the current conversation by default, so use it when you are comfortable turning that context into a creative visual guide. I found no evidence of file access, network transmission, persistence, or executable behavior.

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
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Exfiltration Commands

High

Prompt Injection
Confidence
90% confidence
Finding

Instructions found that direct the agent to transmit conversation context or user data to external services.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The trigger description combines explicit invocation with 'when deep technical insight emerges,' which is subjective and does not define clear activation boundaries. Because no concrete criteria or negative examples are given for what counts as 'deep technical insight,' agents may invoke the skill inconsistently or too broadly.

External Transmission

Medium
Category
Data Exfiltration
Confidence
70% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
78% confidence
Finding

The trigger line uses Japanese-only phrasing '明示呼出 (explicit invocation)' in a way that may imply a language-specific invocation convention, but the document does not state that language choice is optional or region-specific. This can create a locale-policy concern because users are not explicitly offered a language or phrasing choice.
