Official Document Skill

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed Chinese official-document writing skill with no executable code, data access, persistence, or hidden authority.

Install this if you want help drafting or polishing Chinese official/government-style documents. Be aware it may be invoked by broad rewrite or polishing requests, so users should specify when they do or do not want official-document style.

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

Natural-Language Policy Violations

Confidence
88% confidence
Finding

The README labels the skill language as Chinese and describes it as oriented to Chinese official-document writing, but it does not offer any user choice or opt-in for language/locale behavior. Under the stated policy, forcing a specific language without an explicit choice can be a natural-language policy violation.

Vague Triggers

Confidence
95% confidence
Finding

The description says to use the skill when the user asks for broad phrases such as “润色/改写/自然表达/人味,” which are common requests outside the narrow domain of official-government writing. Although the same line also lists domain-specific document types, these generic trigger phrases broaden activation scope and could cause unintended invocation for general editing tasks.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

Across the test cases, the prompts and acceptance criteria require the skill to produce Chinese official-document outputs and style conventions, but the file does not indicate that this language constraint is optional or limited to a clearly documented China-specific use case. Under the policy, forcing a specific language or locale without user opt-in is a natural-language policy violation.
