Four Angle Analysis

Security checks for vulnerabilities and agentic risk

Overview

This is a Markdown-only Chinese structured-analysis framework with no code execution, persistence, credential use, or hidden data flow.

Install this if you want a Chinese-language framework for structured analysis. Be aware it may trigger for many analysis-style requests and may steer outputs into Chinese unless the agent or user explicitly requests another language.

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 activation criteria are extremely broad, covering nearly any request to analyze, describe, research, or decompose an object, industry, problem, or system. This can cause the skill to trigger outside its intended niche, overriding more appropriate skills or steering unrelated user requests into a rigid analysis workflow, which is a scope-control and prompt-routing weakness.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
87% confidence
Finding

The skill content is entirely Chinese and implicitly enforces Chinese-language output without stating that this depends on user preference or locale. In a multilingual environment, this can degrade usability, cause unexpected language switching, and interfere with correct task handling when the user did not request Chinese.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
72% confidence
Finding

The only user-facing description is in Chinese, and the file provides no indication that language selection is optional or that the skill is limited to a Chinese-speaking context. This can create a language/locale policy issue if the skill is surfaced to users who have not opted into that language.

Vague Triggers

Finding

The manifest description only says "四角度结构化分析框架" (four-angle structured analysis framework), which names the skill but does not specify concrete trigger phrases, activation conditions, or scope boundaries. In a manifest file, this lack of specificity can contribute to ambiguous invocation behavior because it is unclear what user requests should or should not activate the skill.

Natural-Language Policy Violations

Confidence
96% confidence
Finding

This markdown file contains user-facing instructional content solely in Chinese from start to end. Under the policy-violation category, forcing a specific language without user opt-in or a stated region-specific justification is a natural-language locale constraint.

Finding

This markdown file is written entirely in Chinese and does not indicate that the user can choose another language or that the content is intentionally limited to a Chinese-speaking context. Under the policy, forcing a specific language without user opt-in can be a natural-language policy violation.
