Security checks for vulnerabilities and agentic risk

Overview

This skill is a read-only cryptocurrency comparison helper whose requested tools and behavior match its stated purpose.

Before installing, confirm you have or want the Gate Info MCP integration. The skill should only retrieve public crypto market, project, ranking, and technical data for comparisons, and its output should be treated as informational rather than investment advice.

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 skill description embeds very broad trigger phrases such as 'compare', 'vs', and 'which is better', which can match many ordinary requests outside the intended coin-comparison scope. In an agentic environment, this can cause incorrect skill activation and unintended tool use, leading to over-collection of data, wrong routing, or confusing outputs.

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

Finding

The trigger scenario section states broad examples but does not define strong boundaries for when the skill should or should not activate. This ambiguity increases the chance of accidental invocation, especially when user text mentions multiple assets or sectors in a non-comparison context.
