Security checks for vulnerabilities and agentic risk

Overview

This skill is a local Chinese-language budget table checker that reads user-provided table text and reports deterministic arithmetic issues without network use or persistence.

Install this only if you want a local checker for Chinese budget execution tables. It does not send data over the network, but it is not a full audit tool: review the disclosed free-version checks and the withheld checks before relying on the output for month-end or management decisions.

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

MCP Tool Poisoning
Confidence
96% confidence
Finding

The skill’s documentation appears to overstate what the free version actually verifies, including broad claims like line-by-line checking and quoting original source evidence for every conclusion. In a finance workflow, users may rely on these claims to approve reconciliations or close books, so capability inflation can cause missed discrepancies and incorrect business decisions even without malicious code execution.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The file’s user-facing comments, guidance, labels, error messages, and disclaimer are all written exclusively in Chinese, indicating the skill is designed to operate in a single language. Under the policy, forcing a specific language without user opt-in is a natural-language policy concern unless the locale restriction is explicitly documented and justified.

Confidence
85% confidence
Finding

The main user-facing instructions and operational guidance in the markdown body are entirely in Chinese, while the file does not state that the skill is restricted to Chinese-speaking users or offer a language choice. Under the policy rule, forcing a specific language without user opt-in can be a natural-language policy violation.

Confidence
94% confidence
Finding

The comment says non-JSON input is treated as plain-text material such as '直接粘贴的合同全文', which contradicts the surrounding manifest and help text that define the skill as a budget execution table checker requiring table headers. This is an active documentation mismatch because it describes a different document type than the code's stated purpose and user guidance.

Natural-Language Policy Violations

Confidence
92% confidence
Finding

The JSON content consists entirely of Chinese-language text and provides no indication that language selection is optional or justified by a region-specific purpose. Under the policy, fixed language/locale behavior without user opt-in can be a natural-language policy violation.
