Claude Prompt

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Claude prompt-writing guide with no code or privileged behavior; the only notable issue is Chinese-language examples that may influence response language.

Installers should expect a Chinese-language prompt-engineering helper. If they want language to follow each user request, they may want the examples clarified, but the package does not contain code, persistence, privileged access, or data-handling behavior.

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
  • System Prompt LeakageDirect Leakage, Indirect Extraction, Tool-Based Exfiltration
  • 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
93% confidence
Finding

The sample system prompt explicitly says '使用中文回复', which imposes a specific language on outputs. The file does not indicate that this is optional or based on user preference, so it conflicts with the policy against forcing a language or locale without opt-in.

Natural-Language Policy Violations

Low

Confidence
91% confidence
Finding

The output-control section includes '指定语言:"用中文回复"' as guidance, but does not clarify that language should be chosen based on user preference. This can be read as endorsing a fixed-language behavior without opt-in.
