Create and refine PowerPoint presentations

Building accurate PowerPoint files often requires layout, XML, and rendering knowledge. This skill provides structured workflows for creating, editing, inspecting, and validating PPTX presentations.

Security Audit

Medium Risk

v11 • 7/22/2026 Open versioned report

Four archive-extraction findings are confirmed because untrusted Office ZIP files are extracted without resource limits. Most static matches are benign documentation, OOXML schemas, or expected presentation tooling. Additional review found resource-exhaustion and path-containment concerns when processing untrusted files. Static review was capped at 400/491 representative findings; omitted static matches are unconfirmed, so automatic publishing stays disabled until manual review.

Medium

ooxml/scripts/validation/base.py:327-349

Relationship validation can probe paths outside the package

Relationship targets are resolved without enforcing containment under the unpacked package directory. A crafted relationship can test whether host paths exist.

The target-resolution logic checks resolved paths but does not show a package-root containment check. This supports filesystem existence probing, not arbitrary file reads.

Medium

scripts/thumbnail.py:219-237

Office conversion lacks resource containment

Thumbnail generation opens supplied presentations with LibreOffice and renders pages without a timeout or resource limits. Malformed documents can consume CPU or memory.

The conversion commands process a supplied presentation and the reviewed invocation lacks a timeout. The impact is resource exhaustion and exposure to the local converter.

Medium

ooxml/scripts/validation/base.py:134-193

Unbounded XML parsing of untrusted package data

Validation parses OOXML XML files without documented size or resource limits. Large crafted XML can amplify resource consumption after extraction.

The validator parses package XML directly and no input-size bounds are evident at these parser call sites. This is a resource-exhaustion concern for untrusted documents.

Capability review items (4)

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

High

ooxml/scripts/unpack.py:17

Archive extract all (zip slip risk)

zipfile.ZipFile(input_file).extractall(output_path)

The code extracts an input-controlled Office ZIP without member-path, size, entry-count, or compression-ratio limits. A crafted archive can exhaust resources during processing.

High

ooxml/scripts/validation/base.py:891

Archive extract all (zip slip risk)

zip_ref.extractall(temp_path)

The code extracts an input-controlled Office ZIP without member-path, size, entry-count, or compression-ratio limits. A crafted archive can exhaust resources during processing.

High

ooxml/scripts/validation/docx.py:201

Archive extract all (zip slip risk)

zip_ref.extractall(temp_dir)

The code extracts an input-controlled Office ZIP without member-path, size, entry-count, or compression-ratio limits. A crafted archive can exhaust resources during processing.

High

ooxml/scripts/validation/redlining.py:70

Archive extract all (zip slip risk)

zip_ref.extractall(temp_path)

The code extracts an input-controlled Office ZIP without member-path, size, entry-count, or compression-ratio limits. A crafted archive can exhaust resources during processing.

What You Can Build

Create a sales deck

Generate a consistent slide deck from a structured outline and approved brand styles.

Update a template presentation

Inspect an existing template, map its layouts, and produce a revised PPTX.

Review presentation quality

Extract content and thumbnails to identify layout, contrast, and text-overflow issues.

Try These Prompts

Create a simple deck

Create a five-slide PowerPoint about [topic]. Use a clear title, concise bullets, and speaker notes.

Build a branded deck

Create a 10-slide PPTX about [topic]. Use these colors: [colors]. Include a title, agenda, evidence, and conclusion.

Edit an existing presentation

Inspect [file.pptx], summarize its layouts and theme, then update slides [numbers] with this content: [content].

Validate an advanced deck

Create a PPTX from [outline] and [template.pptx]. Generate thumbnails, review each slide, and fix overflow or contrast problems.

Best Practices

Inspect the template theme and layouts before creating new slides.
Generate thumbnails and review every slide before delivery.
Keep source files and generated outputs in a dedicated workspace.

Avoid

Do not process untrusted PPTX files without isolation and resource limits.
Do not edit OOXML relationships without validating the final package.
Do not rely on generated slides without visual review.

Frequently Asked Questions

What files can this skill use?

It focuses on PowerPoint PPTX files and their OOXML package contents.

Can it create presentations from scratch?

Yes. It provides an HTML to PPTX workflow for new presentations.

Can it edit an existing presentation?

Yes. It can inspect, modify, pack, and validate presentation content.

Does it support speaker notes and comments?

Yes. The OOXML workflow includes guidance for notes and comments.

How should I review generated slides?

Generate thumbnail grids and check text, alignment, contrast, and overflow.

Should I process unknown PPTX files?

Use an isolated environment because crafted archives can consume system resources.
