Ai Chat Enhancer

Security checks for vulnerabilities and agentic risk

Overview

This skill is mostly a disclosed chat-productivity note, but it has broad trigger phrases and describes chat history/cache behavior users should understand before using.

Before installing, be aware that the skill is documented mainly in Chinese, uses broad activation phrases, and describes storing conversation history and cached responses. Use it only if you are comfortable with chat content being retained by the intended implementation, and prefer narrower trigger wording if your agent supports it.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger

  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

The trigger phrase "Chat" is extremely broad and is likely to match many ordinary user requests unrelated to this specific skill. In an agent environment, this can cause unintended skill activation, prompt/context hijacking, or inappropriate routing of sensitive conversations into this skill's logic and history/cache features.

Natural-Language Policy Violations

Confidence
88% confidence
Finding

Most user-facing instructions and descriptions in the skill are presented only in Chinese, which effectively forces a language choice on users without opt-in. The file does not state that the skill is intentionally region-specific or provide an alternative language path.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
80% confidence
Finding

The trigger phrase "marginnote" is ambiguous and may activate on general discussion of the MarginNote product rather than an intentional request for this skill. This increases the chance of accidental invocation and unintended access to the skill's conversation-management behaviors.
