Zettelkasten Writing Coach

Security checks for vulnerabilities and agentic risk

Overview

This is a prompt-only writing coach for organizing notes, with no code, tools, credentials, persistence, or hidden system changes.

Install this if you want a Chinese-oriented Zettelkasten writing coach. Expect it to structure notes and suggest writing angles from text you provide; do not provide private notes unless you are comfortable sharing them with the agent session.

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
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
Findings (2)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill description and all example interactions are written exclusively in Chinese, and the behavior is framed as responding in that language without any opt-in or alternative locale. Under the policy, language constraints should either offer user choice or be clearly documented as a justified region-specific limitation.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill description, usage instructions, examples, and output guidance are primarily presented in Chinese, which effectively constrains the interaction language. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation unless a justified locale restriction or explicit language choice is provided.
