Produce a .pptx file on disk (headless) instead of driving a live PowerPoint document — for managed-agent sessions with no open Office app.
— the description by Anthropic

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

The pptx-author skill provides a method for agents to create .pptx files in headless environments where live office applications are unavailable. By utilizing Python scripts and the python-pptx library, agents can generate structured slide decks, incorporate templates, and embed data-driven visuals as file artifacts. This skill is designed as a fallback for managed-agent sessions, ensuring that presentation deliverables can be produced and collected by the orchestration layer without requiring a GUI-based office suite.

What it does

  • Generates PowerPoint presentation files directly to the local file system.
  • Supports the use of pre-defined firm templates for consistent branding.
  • Allows for the programmatic addition of slides, text, tables, and charts.
  • Enables the embedding of PNG images for high-fidelity chart representation.
  • Ensures traceability by requiring footnotes for data sourced from local files.

When to use it

  • When operating in a headless or managed-agent environment without access to live office software.
  • When the goal is to produce a finished presentation file as a downloadable artifact.
  • When you need to automate the creation of decks based on data processed in previous steps.
  • When a firm-specific template is available to maintain document standards.

Advantages

  • Enables document creation in environments lacking interactive office applications.
  • Provides a structured, repeatable process for generating slide decks.
  • Supports data-driven presentations by linking content to local model outputs.
  • Maintains professional standards through template integration.

Usage examples

“Create a valuation summary presentation based on the data in model.xlsx.”
The agent writes a Python script to generate a .pptx file, populates it with the valuation data, and saves it to the ./out/ directory.
“Generate a pitch deck using the firm template.”
The agent initializes a presentation using the template found in ./templates/, adds relevant slides, and returns the path to the generated file.

Install

  1. Download the skill as a ZIP:

    mkdir -p .agents/skills && unzip pptx-author.zip -d .agents/skills

Documentation by Anthropic

pptx-author

Use this skill when running headless (managed-agent / CMA mode) and you need to deliver a PowerPoint deck as a file artifact rather than editing a live document via mcp__office__powerpoint_*.

Output contract

  • Write to ./out/<name>.pptx. Create ./out/ if it does not exist.

  • Return the relative path in your final message so the orchestration layer can collect it.

How to build the deck

Write a short Python script and run it with Bash. Use python-pptx:

from pptx import Presentation
from pptx.util import Inches, Pt

prs = Presentation("./templates/firm-template.pptx")  # if a template is provided
# or: prs = Presentation()

slide = prs.slides.add_slide(prs.slide_layouts[5])    # title-only
slide.shapes.title.text = "Valuation Summary"
# ... add tables / charts / text boxes ...

prs.save("./out/pitch-<target>.pptx")

Conventions (mirror the live-Office pitch-deck skill)

  • One idea per slide. Title states the takeaway; body supports it.

  • Every number traces to the model. If a figure comes from ./out/model.xlsx, footnote the sheet and cell.

  • Use the firm template when one is mounted at ./templates/; otherwise default layouts.

  • Charts: prefer embedding a PNG rendered from the model over native pptx charts when fidelity matters.

  • No external sends. This skill writes a file; it never emails or uploads.

When NOT to use

If mcp__office__powerpoint_* tools are available (Cowork plugin mode), use those instead — they drive the user's live document with review checkpoints. This skill is the file-producing fallback for headless runs.

      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,

      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
