What it does

Thumbnail Of PPTX is an agent skill from pamelafox/presentation-skills. Capture a thumbnail image of a slide from a OneDrive/Office presentation link. Opens the PowerPoint web viewer in a headless browser and screenshots the slide canvas, producing a clean 16:9 image with no viewer chrome. Works even when the PPTX is not downloadable (e.g. personal OneDrive shares), since it screenshots the rendered slide rather than converting the file. USE FOR: make a thumbnail from a PPTX, screenshot a slide, title-slide image, OneDrive slide thumbnail, talk thumbnail from slides.

Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `thumbnail_of_pptx.py`).

It sits in Documents & Office, covering PowerPoint presentations, Slides and decks and Cloud office suites. It works with Microsoft PowerPoint and Microsoft OneDrive. The repository describes itself as: Skills for AI agents to process presentations - helpful for teachers and speakers. The licence is MIT.

When your agent uses it

  • : make a thumbnail from a PPTX

What it can do on your machine

Read from SKILL.md and the folder at commit 2b809b3. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • uv

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • aka.ms

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Thumbnail Of PPTX loads about 686 tokens when it runs. Until then it costs about 130 tokens; SKILL.md has 294 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~130
When it runs · the whole SKILL.md, loaded when a task matches
~686

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Capture a thumbnail image of a slide from a OneDrive/Office presentation link. Opens the PowerPoint web viewer in a headless browser and screenshots the slide canvas, producing a clean 16:9 image with no viewer chrome.

Thumbnail of a PPTX slide

Run the thumbnail_of_pptx.py script to capture a slide thumbnail from a OneDrive/Office presentation link:

bash
uv run .agents/skills/thumbnail-of-pptx/thumbnail_of_pptx.py <url> <output_path>

Arguments

  • url (required): A OneDrive sharing link, or an aka.ms short link that redirects to one (e.g. https://aka.ms/my-talk-slides). The link must open the Office Online / PowerPoint web viewer.
  • output_path (required): Path to write the PNG thumbnail (e.g. thumbnail.png). Parent directories are created if needed.
  • --slide N (optional): 1-based slide number to capture. Defaults to 1, the title slide.
  • --scale N (optional): Device scale factor for a crisper image. Defaults to 2.
  • --wait MS (optional): Milliseconds to wait for the slide to render before screenshotting. Defaults to 9000. Increase for large decks or slow networks.

Outputs

A single PNG image of the requested slide, cropped to the slide canvas (roughly 16:9, no PowerPoint viewer UI).

Prerequisites

Playwright browsers must be installed:

bash
uv run playwright install chromium

How it works

  1. Launches headless Chromium and navigates to the URL (following aka.ms redirects to the real OneDrive viewer).
  2. Waits for the network to go idle, then waits a fixed delay for the Office Online viewer to stream in and paint the slide.
  3. Locates the viewer iframe (named wacIframe, with a fallback that finds any frame containing a <canvas>).
  4. Optionally advances to slide N by focusing the canvas and pressing the right-arrow key.
  5. Element-screenshots the slide <canvas> so the output contains only the slide, not the surrounding viewer chrome.

Notes

  • This is complementary to fetch-slides: use fetch-slides when you need the full deck as a PDF (requires LibreOffice for PPTX), and this skill when you just want a lightweight thumbnail image of one slide and the file may not be downloadable.
  • Because it relies on the public web viewer, the sharing link must be viewable by anyone with the link.
