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

Static analysis reported many high and medium findings, but review found no malicious intent, network use, credential access, or prompt injection. The Ruby shell execution and weak cryptography reports are false positives caused by markdown code fences, inline code, argparse text, regex ranges, and Unicode ranges. The remaining real risk is low: the skill runs local Python scripts that read user-selected files and write output PDFs or layout JSON.

Limitations

This report does not claim runtime or sandbox execution and does not prove the absence of side effects.

Local File Read and Write Capability
The helper scripts read user-provided image, layout, OCR, and source-text files, then create output PDFs or layout JSON. This is expected for the skill, but users should choose paths carefully because parent directories are created and outputs may overwrite existing files.
The file operations are directly visible and are required for the skill's document conversion workflow. I did not find evidence of network transmission, hidden persistence, or unauthorized path selection.

Markdown Backticks Misclassified as Shell Execution
The reported Ruby shell execution findings are markdown code fences, inline field names, or example commands for running local scripts. They do not execute automatically and do not contain shell interpolation or remote commands.
The cited locations are documentation blocks and inline code syntax, not Ruby backtick operators in executable source. The only commands shown are explicit local Python invocations for this skill.

Weak Cryptography Findings Are False Positives
The high severity weak cryptography reports do not point to cryptographic algorithms. The cited lines are skill description text, argparse setup, text extraction helpers, and regex or Unicode handling.
No MD5, SHA1, DES, RC4, or related cryptographic call appears at the cited locations. The static pattern matched ordinary words and parser code rather than security-sensitive cryptography.
Low
scripts/ocr_words_to_layout.py:54-55
Unicode Escape Findings Are CJK Range Checks
The Unicode escape findings occur in a helper that detects CJK characters for OCR word joining. This is not obfuscation and does not hide executable content.
The Unicode escapes are literal character range boundaries used by a clearly named CJK detection function. There is no encoded payload, dynamic evaluation, or hidden control flow.
Low
scripts/compose_image_text_pdf.py:144-147
System Reconnaissance Finding Is Error Context
The low severity reconnaissance report points to an exception message that includes rectangle coordinates when text does not fit. It does not collect system details, environment values, host data, or user secrets.
The cited code formats local layout geometry into an error string for debugging PDF text placement. I found no evidence of system enumeration or data exfiltration.
