Security checks for vulnerabilities and agentic risk

Overview

This skill is a local Chinese overtime-pay worksheet checker that reads user-provided input and performs deterministic calculations without network access or persistence.

Install only if you are comfortable running a local Node-based checker on payroll worksheet text. It appears to keep data local, but users should still avoid providing more payroll or employee data than needed and should treat the output as an arithmetic check, not legal advice or proof that overtime records are valid.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection

  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

This skill’s natural-language interface, examples, advice, and result strings are all written in Chinese, and there is no indication that users can choose another language or locale. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
89% confidence
Finding

The user-facing description, usage text, errors, and console output are all written exclusively in Chinese, with no indication that another language can be selected. Under the policy rule for natural-language violations, forcing a specific language without user opt-in is reportable unless the locale constraint is clearly documented and justified.

Intent-Code Divergence

Confidence
91% confidence
Finding

The inline documentation states that non-JSON input will be treated as plain-text material such as a '合同全文' (full contract text). However, the rest of the script and manifest consistently define the skill as an overtime-pay table checker requiring a table with headers, so this documentation broadens the apparent intent beyond what the skill actually claims to handle.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
91% confidence
Finding

The only natural-language content in the file is a Chinese header and data labels, with no indication that the user can choose another language or that the locale is intentionally constrained for a China-specific use case. This can violate language/locale policy because the skill artifact appears to mandate a specific language by default.
