Security checks for vulnerabilities and agentic risk

Overview

This skill is a read-only cryptocurrency comparison helper that uses disclosed Gate Info MCP tools and does not request credentials, persistence, or local file authority.

Install only if you want an agent to query Gate Info market and coin data for crypto comparisons. Review outputs as informational analysis, not investment advice, and expect the skill to ask for clarification when coin symbols or project names are ambiguous.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • 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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The trigger phrases include very broad natural-language terms such as "compare," "vs," "which is better," and "difference," which can match many ordinary conversations that are not actually requests for this coin-comparison workflow. This can cause the skill to activate in unintended contexts, leading to unnecessary tool calls, incorrect routing, or disclosure of analysis the user did not request.

Unrestricted Tool Access

Category
Excessive Agency
Confidence
80% confidence
Finding

Skill grants unrestricted tool access without appropriate constraints. An agent with unfettered tool access can perform arbitrary actions including file modification, network requests, and code execution.

## General Rules

⚠️ STOP — You MUST read and strictly follow the shared runtime rules before proceeding.
Do NOT select or call any tool until all rules are read. These rules have the highest priority.
→ Read `./references/gate-runtime-rules.md`
→ Also read `./references/info-news-runtime-rules.md` for gate-info / gate-news shared rules (tool degradation, report standards, security, and output standards).
- **Only call MCP tools explicitly listed in this skill.** Tools not documented here must NOT be called, even if they

Vague Triggers

Confidence

Finding

The trigger scenario description is underspecified and lacks strong exclusion rules, so requests like broad sector questions or vague asset mentions may still be routed into this workflow. In practice this increases the chance of misclassification, spurious tool usage, and user confusion, especially because the skill can fan out into multiple parallel calls per invocation.
