Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed X/Twitter research workflow that uses Gecho MCP tools and a logged-in browser session to read posts and replies, with no evidence of hidden account actions or destructive behavior.

Install this only if you are comfortable using Gecho with a logged-in Chrome/X session and potentially saving collected public or account-accessible post data locally. Prefer a deliberate save directory, review the external Gecho MCP package and Chrome extension you install, and avoid using it on browser profiles with access you do not want research tools to read.

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
