Security Audit

Safe

v9 • 7/21/2026 Open versioned report

The audit confirmed four unsafe ZIP extraction calls that process Office archives without member-path validation. It also confirmed two documented, user-mediated sudo installation commands; most remaining static findings are syntax, schema, documentation, or expected local document-processing false positives. Static review was capped at 400/506 representative findings; omitted static matches are unconfirmed, so automatic publishing stays disabled until manual review.

These are real local capabilities that may be expected for this skill, so they require review but are not counted as confirmed malicious behavior.

What You Can Build

Build Executive Slide Decks

Create polished decks from briefs, data summaries, and approved visual direction.

Update Branded Templates

Reuse existing template slides while replacing text and preserving layout rules.

Repair Presentation Structure

Inspect OOXML, validate relationships, and repack presentations after targeted edits.

Try These Prompts

Create a Basic Deck

Create a 6-slide PowerPoint about [topic]. Use clear titles, concise bullets, and a professional visual style.

Apply a Template

Use [template.pptx] to create a deck from this outline: [outline]. Match each section to suitable template slides.

Edit Existing Slides

Update [deck.pptx] with these changes: [changes]. Preserve the existing design and validate the result.

Diagnose OOXML Issues

Inspect [deck.pptx] for broken relationships, invalid XML, and layout problems. Fix issues and explain the changes.

Best Practices

Use thumbnail grids after each major edit to catch layout and readability problems.
Validate OOXML immediately after structural changes and before repacking the final file.
Match template layouts to actual content count before replacing placeholder text.

Avoid

Do not force content into a template layout with too many placeholders.
Do not edit raw XML without validating relationships and schema rules afterward.
Do not rely only on text extraction when comments, notes, layout, or media matter.
