Cn Todo Tracker

Security checks for vulnerabilities and agentic risk

Overview

This is a simple local Chinese todo-list skill that stores todos in a disclosed local JSON file and shows no evidence of hidden, remote, destructive, or deceptive behavior.

Install this only if you want a Chinese-language local todo tracker. Todo text is saved on disk at ~/.qclaw/workspace/todos.json until changed or removed, so avoid storing confidential personal, customer, or business details unless local retention is acceptable.

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

Findings (3)

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
93% confidence
Finding

The skill advertises executable commands that read and write a local JSON file, but it does not declare any explicit tool scope or permissions. This can mislead users or hosting systems about the skill's filesystem access, reducing transparency and weakening least-privilege controls even if the intended behavior is only todo storage.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The module docstring explicitly labels the skill as Chinese-only, and the command descriptions and output strings throughout the file are in Chinese. This creates a natural-language locale restriction without any user opt-in or documented justification, which matches the language/locale policy violation criteria.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill notes the storage path, but it does not clearly warn users that task contents are persisted on disk and may contain sensitive personal or business information. Users may enter confidential tasks without understanding that the data remains locally stored, creating privacy and data-retention risk.
