PPTX Author Skill for Claude
Produce a .pptx file on disk (headless) instead of driving a live PowerPoint document — for managed-agent sessions with no open Office app.

5 sections, as written by the authorpptx-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.

Also use when extracting or reorganizing content from .docx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word document. If the user asks for a 'report', 'memo', 'letter', 'template', or similar deliverable as a Word or .docx file, use this skill. Do NOT use for PDFs, spreadsheets, Google Docs, or general coding tasks unrelated to document generation.

Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions \"deck,\" \"slides,\" \"presentation,\" or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill.
