Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward Chinese weekly-report writing skill with no hidden code execution, credential access, or destructive behavior.

Install only if you are comfortable giving the assistant your work-project context and, if using the copy-paste prompt with an external AI service, make sure that service is acceptable for your workplace information.

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

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger phrases "帮我写周报" and "把这段流水账升级成周报" are broad natural-language requests that a user could say in many ordinary contexts, increasing the chance this skill activates unintentionally. Over-broad activation can cause prompt/skill routing collisions, unexpected access to user-provided work content, and execution of this skill when the user intended a different assistant behavior.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The description and core instructions are entirely in Chinese and frame the skill around producing a Chinese-format leadership report, with no indication that the user may choose another language. This creates a natural-language locale constraint without documented opt-in or justification, which matches the language/locale policy violation criteria.

Confidence

Finding

This markdown example presents all instructions, labels, and outputs exclusively in Chinese, which can amount to a language/locale constraint in the skill's natural-language interface. The file does not indicate that Chinese is optional, user-selected, or required for a specific regional purpose.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
93% confidence
Finding

The entire prompt template is written as a prescriptive Chinese-only interaction flow and does not mention any option to use another language. This is a natural-language locale policy concern because it imposes a specific language without documenting user choice or a justified regional constraint.
