Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only backend API design skill whose repository-reading guidance is aligned with analyzing user-provided projects.

Install this if you want Chinese-language backend architecture and API design help. Provide only project paths you intend the agent to inspect, since the engineering-analysis mode tells the agent to read source files such as proto, SQL, Go, and service code.

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 list contains very broad phrases such as '业务方案', '架构设计', '需求分析', and '流程图', which are common in ordinary software conversations and can cause the skill to activate unintentionally. Unintended activation can expose repository structure, influence agent behavior outside the user's precise intent, or cause the skill to overtake more appropriate workflows.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The skill metadata and instructions are entirely written in Chinese and present the skill as operating in that language, but there is no indication that the user can choose another language or that the locale restriction is intentional and justified. This can violate language/locale policy when users have not opted into Chinese output.

Confidence

Finding

The file title and all instructional content are written in Chinese, and the document does not indicate that this language choice is optional or limited to a China-specific audience. Under the policy scope provided, a skill that imposes a specific language without user opt-in can be a natural-language policy violation.

Finding

This markdown file is written entirely in Chinese, including headings, labels, and examples, with no indication that language selection is optional or that the skill is intentionally limited to a Chinese-speaking audience. Under the policy rule for natural-language locale constraints, this can be considered a language policy violation because it imposes a specific language without user opt-in.

Finding

This markdown file is natural-language documentation and all headings, comments, and descriptions are presented in Chinese. Under the policy rule for language/locale, forcing a single language without user opt-in or explicit justification can be a policy violation.
