Security audit
Skill Reviewer
Security checks for vulnerabilities and agentic risk
Overview
This skill is a disclosed local reviewer for other skills and does not show hidden network access, persistence, credential use, or destructive behavior.
Installers should understand that this is mainly a Chinese-language skill-review workflow. It runs local shell/Python validation against skill files and expects skill-creator for deeper review; review the output before acting on suggested changes.
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
- MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
- 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
Medium
- Confidence
- 90% confidence
- Finding
- This markdown file contains core user-facing instructions in Chinese, and the rest of the document continues in Chinese without stating that the skill supports multiple languages or that Chinese is required. That can violate a language/locale policy when users are not given an explicit choice or opt-in.

- Finding
- npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.

Natural-Language Policy Violations
Medium
- Confidence
- 93% confidence
- Finding
- The file’s operative instructions are written in Chinese and do not offer an alternative language or indicate that the skill is intentionally limited to Chinese-speaking users. Under the policy, forcing a specific language without user opt-in is a natural-language policy concern.
