Security checks across malware telemetry and agentic risk

Overview

This skill is a local ebook conversion and organization toolbox whose file access and helper commands match its stated purpose, though users should choose paths carefully because it writes outputs and can copy or symlink books.

Install only if you want a local ebook conversion tool that can read ebook directories and write converted files, reports, copied books, or symlinks. Use explicit input and output directories, prefer --dry-run for organizing libraries, and review commands before running OCR, split/merge, metadata edit, or recursive batch operations.

MCP Least Privilege
Confidence
91% confidence
Finding
The skill advertises and instructs use of scripts that read, write, and invoke shell-adjacent external tools, but it declares no permissions or safety boundaries. This can mislead users and hosting platforms about the skill’s actual capabilities, reducing oversight and increasing the chance of unintended filesystem changes or command execution through supporting tooling.

Tp4

High
Category
MCP Tool Poisoning
Confidence
84% confidence
Finding
The documented behavior expands beyond simple ebook conversion into OCR, image extraction, PDF splitting/merging, reporting, and filesystem organization, while some claimed format support appears inconsistent with actual implementation. This mismatch is dangerous because users may authorize the skill for a narrower task than it really performs, or rely on unsupported behaviors that cause unexpected file handling.

Missing User Warnings

Medium
Confidence
88% confidence
Finding
The skill includes metadata editing and library organization features that can modify files or create symlinks, yet the description does not clearly warn about these side effects. Users may reasonably assume a read-only conversion tool and unintentionally permit destructive or persistent filesystem changes.
