Confirmed finding summary

No confirmed security findings

The completed audit recorded no confirmed security findings. This is not proof that the Skill has no side effects.

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.

The audit found extensive static-analysis noise from Markdown formatting, EC numbers misread as IP addresses, and legitimate BRENDA credential setup. The only confirmed issue is that helper export functions write to caller-provided filenames, which can overwrite local files if used carelessly.

Python file write/append
with open(filename, 'w', newline='') as f:
The helper writes to a filename parameter without constraining the output path. This is intended export behavior, but a careless or model-chosen path could overwrite local files.

Python file write/append
with open(filename, 'w') as f:
The helper writes to a filename parameter without constraining the output path. This is intended export behavior, but a careless or model-chosen path could overwrite local files.

Risk findings

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

No confirmed security findings were recorded for this completed audit.

Remediation

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

  1. FIX-001
    Medium
    Export helpers accept unrestricted output filenames.
    Constrain exports to a dedicated output directory, normalize paths, and refuse parent-directory traversal or absolute paths unless explicitly confirmed by the user.
  2. FIX-002
    Low
    BRENDA credential setup relies on local environment variables or .env files.
    Document that credentials must never be committed, should use least-privilege accounts when possible, and should be rotated if exposed.
