pptx
Read, edit, or create PowerPoint .pptx files. Trigger this skill whenever the user mentions a deck, slides, slide deck, presentation, or a `.pptx` filename — whether the goal is to extract text, modify an existing deck, build one from scratch, or prepare slides for review. Three execution paths are supported: text extraction (always available), template editing (unzip → patch slide XML → repack), and creation from scratch (python-pptx for Python or PptxGenJS for Node).

2 findings: 1 critical severity, 1 medium severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
The URLs are mostly official docs and GitHub repos (low risk), but https://clawhub.ai/ivangdavila/powerpoint-pptx is a third‑party/unfamiliar hosting site used to distribute the skill source and should be treated as suspicious/untrusted for downloads.
W013: Attempt to modify system services in skill instructions.
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
The skill's troubleshooting tells the user to run system package installs with sudo (e.g., `sudo apt-get install -y libreoffice` and `sudo apt-get install -y poppler-utils`), which instructs altering the host system and requesting elevated privileges.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
The `pptx` skill’s Path A runtime flow reads arbitrary text from an outsider-provided `.pptx` by extracting slide and notes text using `scripts/extract_text.py` (via python-pptx), so free text authored by the deck creator becomes LLM input at runtime.
