Security checks for vulnerabilities and agentic risk

Overview

This skill is a local Chinese accounting reconciliation checker that reads user-selected materials and prints scoped findings without network use, file writes, or persistence.

Install only if you are comfortable running a local Node.js checker over the selected financial folders. Review the reported checks_not_run and sub_checks_not_run sections carefully, and treat results as reconciliation assistance rather than audit, assurance, or accounting judgment.

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
  • 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

Finding

This finding is a weaker variant of the same scope-mismatch issue: the documentation emphasizes one-line per-client conclusions, while the actual output may include richer structured data and partial coverage states. That is still a real trust issue, but less severe than the claims that entire check families are implemented when they are not.

Description-Behavior Mismatch

High
Category
Not specified by scanner
Confidence
98% confidence
Finding

The skill metadata advertises a 14-item receivables/reconciliation pack, but this file explicitly implements only the advance-receipt / revenue-recognition subset and marks other checks as withheld or out of scope. In a financial review workflow, that mismatch can mislead users into believing the full control set ran, causing material omissions in audit or risk detection even though the code itself is not overtly malicious.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The file’s user-facing natural-language strings, comments, sample input, error messages, and disclaimer are entirely in Chinese, with no indication that another language is supported or that Chinese is a documented locale-specific requirement. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

All comments, prompts, error messages, and result text presented to users are written in Chinese, including required input guidance and returned findings text. The file does not indicate that the skill is China-specific or provide any user opt-in or alternative locale, which can violate language/locale policy requirements.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

This code’s natural-language interface, messages, and disclaimers are written exclusively in Chinese, and there is no indication that users may choose another language. Under the policy for natural-language violations, forcing a specific language without user opt-in should be flagged.

Natural-Language Policy Violations

Medium
Category

Confidence
95% confidence
Finding

This JavaScript file’s natural-language interface is entirely in Chinese, including the top-level description and later user-facing advice/error text, with no indication that the skill is region-specific or that users may choose another language. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The file explicitly states it is only a free-tier subset and omits several checks, while the surrounding skill metadata promises a much broader 14-item, per-customer review. This creates a security/integrity gap: users may rely on the tool for comprehensive financial review when it actually performs only limited arithmetic checks, causing material issues to be missed without obvious warning at the skill level.
