Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed, read-only crypto coin analysis workflow that gathers public market, news, technical, and sentiment data through named Gate MCP tools.

Before installing, confirm you trust the Gate MCP server source and understand that the skill will query external/public crypto market, news, and sentiment services. Treat its output as informational analysis, not financial advice.

A.I.G

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

Scope Creep

Medium
Confidence
97% confidence
Finding
The manifest states that no permissions are required, yet the skill clearly depends on multiple MCP tools and an external MCP server for market, news, and sentiment retrieval. This creates a security and governance mismatch: deployment systems, reviewers, or policy engines may under-classify the skill's capabilities, leading to unvetted data access and weaker auditability.

Content
## 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
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.

Vague Triggers

Medium
Confidence
95% confidence
Finding
The trigger phrases are broad, conversational language such as 'how is BTC' or 'worth buying,' which can cause the skill to activate in situations where the user intended a narrower or different workflow. Misrouting is security-relevant here because the skill performs multi-tool data gathering and may bypass a more appropriate specialized skill with different safeguards or output constraints.
