CORE Prism (CORE 四维战略透镜)

Security checks for vulnerabilities and agentic risk

Overview

This is a profile-aware strategic analysis prompt skill with no executable code, network behavior, persistence, or destructive actions.

Before installing, review what you keep in USER.md because this skill is designed to use that profile context for tailored strategic advice. Avoid storing sensitive personal, financial, credential, or confidential business details there unless you are comfortable with them being used in analyses.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
80% confidence
Finding

The title presents the skill as "CORE 四维战略透镜," indicating a Chinese-language framing, while the README does not state that language is optional or user-selectable. Under the policy, forcing or implying a specific language/locale without opt-in can be a natural-language policy violation.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The documentation states as a matter of behavior that 'The skill reads your USER.md to understand your context.' Elsewhere it says 'The skill auto-reads it,' yet the repository contents described are only markdown files and 'No dependencies,' with no implementation shown that could actually read USER.md automatically.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The README states the skill reads USER.md to understand user context, but it does not clearly warn users that personal context data may be automatically accessed. In an agent setting, implicit access to user profile/context files can expose sensitive personal, professional, or strategic information beyond what the user intended to share for a specific task.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The instruction 'Read USER.md First' reinforces implicit automatic access to a user context file without an accompanying privacy warning or consent mechanism. In a strategic-analysis skill, USER.md may contain highly sensitive background such as projects, resources, plans, or personal details, making silent ingestion more dangerous because outputs could inadvertently reveal or overuse private context.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The activation criteria are broad enough to trigger on common activities like analyzing news, reading, or making strategic decisions, which increases the chance the skill runs in situations the user did not specifically intend. Because the skill also reads USER.md for personalization, overly permissive activation expands unnecessary exposure of personal context and can bias outputs without clear user awareness.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill explicitly instructs the agent to read USER.md to personalize outputs, but it does not provide a clear privacy notice or require consent at the point of use. This creates a data-minimization and transparency problem: personal profile data may be accessed during ordinary analysis tasks even when the user did not expect profile-based enrichment.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
75% confidence
Finding

The instruction to always use second-person ("you") imposes a fixed communication style regardless of user preference. While not a severe issue, it is a natural-language policy concern because it constrains output style without offering the user a choice or making the preference optional.
