Evidence Cleaner

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only evidence-cleaning skill with no executable code, persistence, credential handling, or hidden authority.

Install this if you are comfortable using a Chinese-language evidence-cleaning workflow. Review the output before relying on it, especially when it drops or downranks evidence, because those are judgment calls about source quality rather than guaranteed facts.

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
  • 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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

This markdown file contains user-facing natural-language instructions entirely in Chinese, but it does not state that the skill is China-specific or provide any user opt-in for language preference. That can violate a language/locale policy when users may reasonably expect skills to be accessible in their chosen language.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The entire skill reference is written only in Chinese and provides no indication that users may choose another language or locale. Under the stated policy, language constraints should be optional or explicitly justified as region-specific; neither appears here.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

This markdown file presents all skill examples, headings, and instructions in Chinese only, with no indication that the user can choose another language. Under the language/locale policy rule, forcing a specific language without user opt-in is a natural-language policy violation unless the locale restriction is explicitly justified.

Natural-Language Policy Violations

Confidence
89% confidence
Finding

This markdown file contains natural-language instructions exclusively in Chinese, and there is no indication that users can opt into another language or that the skill is intentionally limited to a Chinese-speaking context. Under the language/locale policy rule, forcing a specific language without user opt-in is a policy concern.
