How to use the PPT Master presentation builder agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
PPT Master is an agent skill: a packaged set of instructions and scripts that an AI agent loads so it can build PowerPoint (PPTX) presentations in a consistent, step-by-step way. This guide explains what the skill makes the agent do, how to install it, how to ask for work in plain language, and what to check before you trust the output. By the end you will be able to install the skill, trigger the right workflow, and review the editable deck it produces.
PPT Master presentation builderhugohe3/ppt-master · MIT Download the skill Quick start
- 1Download the ZIP. Download the ppt-master skill ZIP from this page. Keep the file somewhere you can find it.
- 2Unzip into a skills folder. Unzip the skill into ~/.claude/skills/ for personal use, or into a project's .claude/skills/ folder for one project.
- 3Or upload in the Claude apps. If you use the Claude apps, go to Settings, then Capabilities, then Skills, and upload the skill.
- 4Confirm Python 3 is available. Make sure python or python3 runs on your system path, since the skill's scripts need it.
- 5Ask for a deck in plain language. Describe the slides you want and mention PPTX, PPT, slide deck or courseware so the skill triggers.
- 6Review the editable PPTX. Open the generated file, check layout, text fit and content, and fix anything the agent got wrong.
What the ppt-master skill makes the agent do
Once installed, the agent follows a structured workflow to create PowerPoint presentations. The output is an editable PPTX file, not a flat image. The skill covers building new slides, reusable brand or layout templates, reconstructing the visuals of a page, and enhancing a deck you already have.
The skill routes each request to one specific procedure and loads only the instructions for that route. Its entry file describes six routes: generating a PPTX from an image, beautifying a PPTX, a default generation workflow, an explicit quick generation workflow, creating a template, and editing a native PPTX. The skill also mentions adding narration or animation to a deck.
- Generate a new deck or slide set as an editable PPTX
- Build reusable Brand, Style, Layout or Deck workspaces and templates
- Fill native PPTX templates
- Reconstruct a page image as editable slides
- Beautify or redesign an existing PPTX
- Enhance a finished PPTX file
Install the ppt-master skill from the ZIP download
Download the ZIP of the ppt-master skill from this page. Unzip it so that the skill folder sits in one of the locations agents read skills from. For a personal install, put it in ~/.claude/skills/. For a single project, put it in the project's .claude/skills/ folder.
If you use the Claude apps, you can instead upload the skill under Settings, then Capabilities, then Skills. Use whichever method matches how you run your agent. After installing, start a new session so the agent can see the skill.
- Personal install: ~/.claude/skills/
- Project install: .claude/skills/ inside your project
- Claude apps: Settings → Capabilities → Skills, then upload
Check Python and the skill's scripts before the first run
The skill needs Python 3 on your system path, available as python or python3. It also needs access to the skill's scripts folder, since the workflow calls scripts such as scripts/attribution_guard.py. The skill runs scripts and does not use the network, according to its listing.
Every run starts with a startup integrity check. The agent runs the guard script first, and if the result is not zero, the skill stops. The agent is not supposed to inspect, repair or bypass this check. On Windows, a python3 command that never starts is not treated as a failed check; the agent should rerun with python instead.
- Python 3 must be available as python or python3
- The scripts folder must be readable by the agent
- The startup integrity check must pass or the skill will not continue
- The skill does not use the network
python3 "${SKILL_DIR}/scripts/attribution_guard.py"Trigger the skill with natural requests
You do not need special syntax. Describe the presentation you want in plain words, and include words such as presentation, PPT, PPTX, slide deck or courseware. The skill also triggers on verbs such as create, generate, reconstruct, regenerate, beautify, redesign, template, fill and enhance. You can also name the skill directly by mentioning ppt-master.
The agent then picks one route based on your request. Requests for a template go to the template route, a page image to be turned into slides goes to the image route, and a request to improve an existing file goes to the beautify or edit routes.
- Create a 10-slide deck on our Q3 results for an internal team meeting
- Use ppt-master to make a reusable branded template for our monthly updates
- Beautify this PPTX and keep the content but redesign the layout
- Turn this page image into editable slides
- Fill this PPTX template with the data in my spreadsheet notes
- Add narration or animation to this slide deck
Review the output and what it can and cannot do
Expect a first draft. The skill is designed to produce editable slides you can open and change. Generated layouts still need a person to check them, including spacing, text fit and how each slide reads. Plan a review pass before you share the deck.
The skill is not the right tool when you only need a short text outline or a single chart; a simpler tool is enough for those. It also depends on the startup check passing, so if you cannot accept that check, this skill is not suitable.
- Check every slide visually before presenting
- Treat generated layouts as drafts that need human review
- Use a simpler tool for a plain outline or one chart
Safety notes on scripts and files
The skill runs local scripts as part of its workflow, so review what you install and where it lives. The entry file requires the integrity guard to run first and says that a non-zero result stops the skill immediately. The skill's listing states it does not use the network.
The skill's folder includes reference material such as animation notes, artifact ownership notes, image comparison galleries and sponsor notices. The image comparison folders are described as reference assets, not an example project, and they are not a second confirmation control for colours.
- Run the skill only from a folder you trust
- Keep the scripts folder intact so the integrity check can run
- The skill's listing states it uses no network access
- Reference folders are material for the agent, not a project to copy
What people use it for
- Building a first-draft slide deck or courseware quickly as an editable PPTX
- Creating reusable branded templates for recurring presentations
- Redesigning an existing PPTX while keeping its content
- Turning a page image into editable slides
- Filling a native PPTX template with new content
Frequently asked questions
Is the ppt-master skill free to use?
The skill is published under the MIT licence, as stated in its listing. This page does not state any price, so check the download page for current terms.
What do I need to run the ppt-master skill?
You need Python 3 available as python or python3 on your system path, and access to the skill's scripts folder. The skill runs scripts and does not use the network, according to its listing.
Where do I install the ppt-master skill?
Unzip it into ~/.claude/skills/ for personal use or into a project's .claude/skills/ folder. In the Claude apps, you can upload it under Settings, then Capabilities, then Skills.
Why does the skill stop immediately?
The skill runs a startup integrity check through scripts/attribution_guard.py first. If that check returns a non-zero result, the skill stops and does not continue. On Windows, if python3 never starts, rerun the check with python.
Can ppt-master edit an existing PowerPoint file?
Yes. The skill includes routes for beautifying an existing PPTX, editing a native PPTX, filling native templates and enhancing a finished PPTX. Ask for the change in plain words and mention the file.
How does ppt-master compare with other slide tools?
The source does not compare it with other tools. It is best for a first-draft editable deck, reusable branded templates or redesigning an existing file. For only a short outline or one chart, the source suggests a simpler tool is enough.

Our verdict
Use ppt-master if you need an editable PPTX first draft, reusable branded templates, or a redesign of an existing deck, and you are comfortable running a local Python-based skill with an integrity check. Pick a simpler tool if you only need a text outline or a single chart, or if you need to guarantee every design detail without human review.
