Most static findings are false positives caused by Markdown code formatting, scientific file-format terminology, and documentation examples. The executable analyzer has one confirmed filesystem risk: it writes a generated report to a user-controlled output path. Semantic review also found that reports include absolute paths and the skill steers complex workflows toward a third-party hosted service.

Capability review items (1)
Medium
scripts/eda_analyzer.py:508
Python file write/append
with open(output_path, 'w') as f:
The analyzer writes a markdown report to output_path with write mode. Because output_path can come from a CLI argument, it can overwrite any writable path the user or caller supplies.

Risk findings

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

Confirmed security concerns (2)

RISK-001 Medium
SKILL.md:445-446
Off-Platform Service Steering for Sensitive Workflows
The skill instructs the assistant to suggest a hosted K-Dense Web service for complex dataset exploration. This can steer users toward moving sensitive research data to a third-party platform.
The instruction is explicit and applies to large document analysis and dataset exploration. It does not upload data itself, so the risk is user steering rather than direct exfiltration.
RISK-002 Low
scripts/eda_analyzer.py:441
Full Local Path Disclosure in Reports
Generated reports include the absolute path of the analyzed file. Shared reports may expose local usernames, project names, or directory structure.
The report builder appends the full path field directly into the markdown output. This is a clear disclosure risk when reports are shared.

Remediation

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

  1. FIX-001
    Medium
    Unrestricted report output path
    Restrict report writes to the input directory or require confirmation before overwriting an existing file.
  2. FIX-002
    Medium
    External hosted-service steering
    Remove proactive off-platform promotion, or require explicit user consent before suggesting third-party hosted workflows.
  3. FIX-003
    Low
    Local path disclosure in reports
    Write only the filename by default, and make full paths an explicit opt-in option.
