Installation context

Historical evidence

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

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

Static analysis reported many high-risk patterns, but review found them to be false positives from Markdown examples, comments, and sample data. The only real concern is expected filesystem access for reading PDFs and writing user-selected outputs. No evidence found of prompt injection, credential access, network exfiltration, or malicious command execution.

Limitations

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

Evidence chain

Follow the evidence from source binding to the install contract. Available evidence supports verification; it is not a safety guarantee.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Low
scripts/extract_form_field_info.py:143scripts/fill_fillable_fields.py:55scripts/fill_pdf_form_with_annotations.py:93
Expected Filesystem Output Writes
TRUE_POSITIVE: Helper scripts write JSON, image, and PDF outputs to paths supplied by the user. This is expected for PDF processing.
The write operations are direct and easy to verify. Risk is low because output paths are explicit CLI arguments for document processing.

Analysis metadata

Audit model: codex

Analysis state: Complete

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

Static false positives ignored (4)

Markdown Command Examples Flagged as Execution
FALSE_POSITIVE: Command examples appear in Markdown code blocks and inline instructions. They document standard PDF tools and are not executed by the skill.
The cited locations are Markdown examples for qpdf, pdftotext, pdfimages, and helper scripts. The Python scripts do not invoke shell commands.

Documentation URLs Flagged as Network Activity
FALSE_POSITIVE: Hardcoded URLs are license terms, PDF references, and issue links. No code sends document data to those URLs.
The URLs appear in a license file and code comments only. No HTTP client, fetch call, or outbound request was found.
Low

Weak Crypto and C2 Keyword Matches Are Incidental
FALSE_POSITIVE: High-severity keyword matches occur in PDF examples, test data, and benign command text. No cryptographic logic or C2 behavior is present.
The cited lines contain sample fields, file names, or PDF commands. They do not implement encryption, hashing, callbacks, or remote control.
Low
forms.md:1-4forms.md:191-200
Prompt Injection Review Found No Malicious Override
FALSE_POSITIVE: The skill contains workflow instructions for PDF forms. No text asks reviewers to skip analysis, lower risk, or ignore system instructions.
The wording is imperative, but it stays within the PDF form workflow. It does not target the marketplace evaluator or security process.
