marky-md-to-docx
Convert Markdown files to DOCX format using markdown-it
This report shows the evidence for marky-md-to-docx@1.0.0, the only known version.
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe package includes agent instructions that direct agents to perform recursive external research, including Google searches, which conflicts with this review's no-network boundary. The runtime package behavior otherwise appears consistent with a Markdown editor and converter.
Static reason
No blocking static signals were detected.
Trigger
An AI coding agent reads the package's .github agent configuration.
Impact
Could cause an agent to send URLs or search queries to external services and follow additional links.
Mechanism
Instructions require recursive fetching of user-provided URLs and searching Google with a fetch tool, crossing the review's no-network boundary.
Attack narrative
When an AI agent reads the added repository instructions, it is told that extensive internet research is mandatory and directed to recursively fetch URLs and search Google. This is a review boundary escape; the package's normal converter and editor behavior does not show the same attack.
AI rationale
The package includes agent instructions that direct agents to perform recursive external research, including Google searches, which conflicts with this review's no-network boundary. The runtime package behavior otherwise appears consistent with a Markdown editor and converter.

Decision evidence
public snapshotAI called this Malicious at 87.0% confidence as Malware with low false-positive risk.
Evidence for block
- The added agent instructions say the task cannot be solved without extensive internet research and direct agents to recursively fetch URLs.
- The same internet research directive appears in both the Beast agent file and Copilot instructions.
- The Beast agent file tells agents to search Google using a fetch tool.
- The manifest declares the Markdown converter and local server as its entry points.
- The converter reads the user-selected Markdown file and writes the requested DOCX output.
- The README describes the local server as loopback-only.
Evidence against
- The manifest has no install, preinstall, or postinstall lifecycle scripts.
- The converter's file access is tied to its command-line input and output paths.
- The browser app's CDN dependencies serve editor, diagram, math, and export features.
