Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrow browser helper that opens Stack Overflow in Brave and does not show hidden code, persistence, credential handling, or content-changing behavior.

Install this only if you want an agent skill that can focus Brave, reuse an existing Stack Overflow tab or logged-in browser session, and open Stack Overflow for you. It does not ask for or store credentials, and it tells the agent to stop at login or account changes.

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

Vague Triggers

Medium
Confidence
86% confidence
Finding
The manifest says to use this skill when the user asks to "open, visit, or go to Open Stack Overflow," which is a loosely specified invocation pattern and does not provide exclusions or narrower trigger constraints. In a markdown/manifest context, this can lead to unintended activation because the trigger guidance is phrased broadly rather than as a precise command list or scoped condition.

Natural-Language Policy Violations

Medium
Confidence
93% confidence
Finding
The description mandates opening the site in the user's Brave browser, and the rest of the document consistently requires Brave specifically. This is a natural-language policy concern because it imposes a specific application choice without offering opt-in, alternatives, or a documented reason for the browser constraint.
