Web Tools

Security checks for vulnerabilities and agentic risk

Overview

This is a small web tools skill with disclosed, purpose-aligned web search and GitHub Pages deployment behavior, but users should confirm before publishing anything.

Install only if you want an agent to help with web search, extraction, performance checks, document conversion, and GitHub Pages publishing. Before any deployment, confirm the exact folder, repository/account, commit contents, and whether secrets or private files are excluded.

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

Missing User Warnings

Medium
Category

Confidence
91% confidence
Finding

The skill explicitly advertises fully automated static site deployment, including repository creation, git initialization, Actions configuration, pushing, and going live, but provides no warning that it may create remote repositories or publish local content. This can lead to unintended code publication, exposure of sensitive files, or unexpected modifications to a user's GitHub account if invoked without clear consent and confirmation boundaries.

Missing User Warnings

Low
Category

Confidence
88% confidence
Finding

The skill advertises web search and content extraction through external services but does not disclose that user queries, URLs, or fetched content may be transmitted to third-party providers. This creates a privacy and data-handling risk, especially if users supply internal links, sensitive topics, or proprietary content assuming the tool operates locally.
