Security checks for vulnerabilities and agentic risk

Overview

This is a local worksheet-checking skill for bill discount interest calculations, with no evidence of network use, persistence, credential access, or hidden behavior.

Before installing, users should know this tool runs a local Node script over worksheet text they provide. It does not appear to send data out or make changes, but it is scoped to the listed free checks and should not be treated as financial or legal advice or as a complete bill-discounting audit.

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
  • 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

Vague Triggers

Confidence

Finding

The manifest description says the trigger words include "票据贴现" and "计息天数", which are broad domain terms rather than specific invocation phrases. Users discussing bill discounting or interest-day calculations generally could match these phrases unintentionally, and the file does not provide exclusion conditions or negative examples to narrow when the skill should activate.

Natural-Language Policy Violations

Finding

This JavaScript file contains natural-language documentation, prompts, advice, labels, and result messages entirely in Chinese, and there is no indication that the skill is region-specific or that users may opt into another language. Under the policy rule for language/locale constraints, forcing a single language without opt-in is a natural-language policy concern.
