Excel 处理

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent Excel automation guide that works with local spreadsheet files and does not show hidden, networked, persistent, or deceptive behavior.

Install if you want local Python/openpyxl guidance for Excel automation. Review generated scripts before running them on important spreadsheets, keep backups, and be careful with files containing personal, financial, or business-sensitive data.

A.I.G

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

Vague Triggers

Finding

The skill metadata uses broad trigger phrases such as '用Python处理Excel' and '批量合并Excel' without clear exclusion criteria, which can cause the agent to invoke this skill for loosely related requests. That increases the chance of inappropriate routing, unnecessary file-handling guidance, or accidental use in contexts the user did not intend.

Natural-Language Policy Violations

Finding

The output contract appears to prescribe a fixed Chinese-language deliverable format without stating that the assistant should follow the user's language preference. This can cause policy or UX issues by overriding user intent, reducing clarity for non-Chinese users, and increasing the chance of misunderstanding around file operations or formula caveats.
