Security checks for vulnerabilities and agentic risk

Overview

This skill is a local Chinese-language finance self-check tool that reads user-provided reconciliation data and reports arithmetic issues without network use or persistence.

Install only if you want a Chinese-language, local finance-table arithmetic checker. Review outputs as reconciliation aids, not accounting, audit, tax, or legal conclusions, and run it only on files you intentionally provide to the Node script.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

MCP Tool Poisoning
Confidence
95% confidence
Finding

A skill presented as a three-part monthly review but implemented as only AR aging creates control-gap risk: users may stop additional review work based on incomplete coverage. In business-ops skills, deceptive or inaccurate capability claims are particularly harmful because they influence financial decisions and period-close signoff.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

An ambiguous trigger in the summary broadens activation beyond the intended reconciliation package. In combination with available tools, even a low-severity activation bug can lead to unnecessary file access or execution paths in routine finance conversations.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

Overly broad trigger phrases can cause the skill to activate during ordinary finance discussions unrelated to this specific self-check workflow. That increases the chance of accidental invocation, inappropriate tool use, and user confusion about which workflow is in effect.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
84% confidence
Finding

The skill claims to be fully local and no-network, yet it allows Bash and documents shell-based execution. Bash is a highly privileged tool that can read arbitrary local files, spawn processes, and access the network, so the declared trust boundary is broader than represented to users.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The file’s natural-language instructions, input requirements, missing-input advice, sample data, and disclaimer are all written exclusively in Chinese, and the expected section headers are Chinese-only. There is no indication that users may choose another language or that the skill is intentionally restricted to a Chinese-speaking or China-specific compliance context.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

This JavaScript file contains natural-language comments, prompts, advice, notes, and disclaimers entirely in Chinese, including the user-facing messages returned by run(). Under the policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale constraint is explicitly documented and justified, which it is not here.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

This JavaScript file embeds its descriptive comments, sample data, column labels, error/advice text, and result summaries entirely in Chinese. That creates a locale/language constraint for users and downstream consumers without any documented opt-in or alternative language choice, which matches the policy's language/locale violation criterion.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

This JavaScript file contains its primary docstring, labels, sample input, and user-facing messages entirely in Chinese, indicating the skill is designed to operate in a single language. There is no opt-in, locale selection, or explicit justification that the skill is region-specific, which can violate language/locale policy requirements.

Intent-Code Divergence

Low
Category
Not specified by scanner
Confidence
97% confidence
Finding

The module documentation says input may contain a section headed === 银行流水对账 ===, but the implementation only recognizes the three names in BUNDLE_CHECKS: 集团内部往来对账与抵消核对、供应商应付对账、应收账款账龄核对. This is an active documentation/code mismatch because a user following the documented example would provide a section the code never runs.
