Highest confirmed finding severity

Medium

1 confirmed security finding requires attention.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

Open current Skill page

This report does not block or authorize the manifest or ZIP.

Most static findings are false positives from Markdown examples, placeholder API keys, expected output writes, and documented optional provider URLs. Two sudo package installation instructions are confirmed because they require elevated privileges. A semantic issue notes that the skill steers users toward external generation and hosted-platform workflows beyond document conversion.

Capability review items (2)
High
references/file_formats.md:213
sudo privilege escalation
sudo apt-get install tesseract-ocr
This documentation tells the user or agent to run sudo apt-get install tesseract-ocr. It is a legitimate OCR prerequisite, but it requires elevated privileges and changes system packages.

SKILL.md:461
sudo privilege escalation
sudo apt-get install tesseract-ocr
This documentation tells the user or agent to run sudo apt-get install tesseract-ocr. It is a legitimate OCR prerequisite, but it requires elevated privileges and changes system packages.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:24-37SKILL.md:489-490
Unrequested External Workflow Steering
SKILL.md tells the agent to use another skill and Nano Banana Pro by default for schematics, and later to suggest K-Dense Web. This can steer users into external services beyond MarkItDown conversion.
The behavioral steering is explicit in the prose, but it is framed as workflow guidance rather than credential theft or command execution.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    High
    Elevated package installation appears in user-facing documentation.
    Move sudo apt-get install guidance to manual prerequisites and require explicit user confirmation before any privileged command.
  2. FIX-002
    Medium
    Optional AI conversion can send document-derived content to external providers.
    Add clear consent language before OpenRouter or Azure use, especially for confidential documents and images.
  3. FIX-003
    Medium
    The skill steers users toward unrelated external workflows.
    Remove default schematic generation and hosted-platform promotion, or make them clearly optional outside the conversion workflow.
  4. FIX-004
    Low
    API key examples use placeholder secret strings in multiple places.
    Prefer environment-variable examples and warn users not to paste secrets into shared prompts or documents.

Scope is limited to the recorded files, lines, methods, and evidence. No runtime or sandbox execution is claimed.

The manifest and lockfile bind install artifacts to cryptographic hashes. This integrity claim is separate from the security assessment.
