PPT生成器

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; 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. If a .pptx file needs to be opened, created, or touched, use this skill.

Quick Reference

Task	Guide
Read/analyze content	python -m markitdown presentation.pptx
Edit or create from template	Read editing.md
Create from scratch	Read pptxgenjs.md

Reading Content

bash

# Text extraction
python -m markitdown presentation.pptx

# Visual overview (requires LibreOffice + Poppler)
python scripts/thumbnail.py presentation.pptx

# Raw XML
python scripts/office/unpack.py presentation.pptx unpacked/

Editing Workflow

Read editing.md for full details.

1. Analyze template with thumbnail.py
2. Unpack → manipulate slides → edit content → clean → pack

---

Creating from Scratch

Read pptxgenjs.md for full details.

Use when no template or reference presentation is available. Uses pptxgenjs (Node.js) to programmatically generate .pptx files.

Design Ideas

Don't create boring slides. Plain bullets on a white background won't impress anyone. Consider ideas from this list for each slide.

Before Starting

• Pick a bold, content-informed color palette: The palette should feel designed for THIS topic.
• Dominance over equality: One color should dominate (60-70% visual weight), with 1-2 supporting tones and one sharp accent.
• Dark/light contrast: Dark backgrounds for title + conclusion slides, light for content. Or commit to dark throughout for a premium feel.
• Commit to a visual motif: Pick ONE distinctive element and repeat it.

Color Palettes

Theme	Primary	Secondary	Accent
Midnight Executive	1E2761 (navy)	CADCFC (ice blue)	FFFFFF (white)
Forest & Moss	2C5F2D (forest)	97BC62 (moss)	F5F5F5 (cream)
Coral Energy	F96167 (coral)	F9E795 (gold)	2F3C7E (navy)
Warm Terracotta	B85042 (terracotta)	E7E8D1 (sand)	A7BEAE (sage)
Ocean Gradient	065A82 (deep blue)	1C7293 (teal)	21295C (midnight)
Charcoal Minimal	36454F (charcoal)	F2F2F2 (off-white)	212121 (black)

Typography

Header Font	Body Font
Georgia	Calibri
Arial Black	Arial
Calibri	Calibri Light
Cambria	Calibri
Trebuchet MS	Calibri

Element	Size
Slide title	36-44pt bold
Section header	20-24pt bold
Body text	14-16pt
Captions	10-12pt muted

Avoid (Common Mistakes)

• Don't repeat the same layout across slides
• Don't center body text — left-align paragraphs and lists; center only titles
• Don't default to blue — pick colors that reflect the specific topic
• Don't create text-only slides — add images, icons, charts, or visual elements
• NEVER use accent lines under titles — use whitespace or background color instead

QA (Required)

Assume there are problems. Your job is to find them.

Content QA

bash

python -m markitdown output.pptx

Check for missing content, typos, wrong order.

When using templates, check for leftover placeholder text:

bash

python -m markitdown output.pptx | grep -iE "xxxx|lorem|ipsum|this.*(page|slide).*layout"

Visual QA

Convert slides to images, then inspect visually:

bash

# Convert to PDF first (requires LibreOffice)
python scripts/office/soffice.py --headless --convert-to pdf output.pptx

# Convert PDF to JPEG images (requires Poppler - pdftoppm)
pdftoppm -jpeg -r 150 output.pdf slide

This creates slide-01.jpg, slide-02.jpg, etc.

---

Dependencies

Install these once (managed under ~/.workbuddy/binaries/):

bash

# Python: text extraction
pip install "markitdown[pptx]" Pillow defusedxml

# Node.js: create presentations from scratch
npm install -g pptxgenjs

# Optional (for visual QA):
# - LibreOffice (soffice) for PDF conversion
# - Poppler (pdftoppm) for PDF-to-image conversion

Windows Note: soffice.py in this localized version skips the AF_UNIX socket shim (Linux-only). It simply runs soffice directly via subprocess.run. Make sure LibreOffice is installed and soffice is in your PATH, or set the SOFFICE_PATH environment variable to the full path of soffice.exe.

---

Localization Notes (vs. upstream)

1. scripts/office/soffice.py — Removed AF_UNIX / LD_PRELOAD shim logic. Windows never blocks AF_UNIX, so the script just delegates to soffice directly.
2. scripts/office/unpack.py / pack.py — Use defusedxml.minidom (same as upstream). No changes needed.
3. Node.js path — Use the managed Node path: C:\Users\Administrator\.workbuddy\binaries\node\versions\node-v20.18.0-win-x64\node.exe and the managed npm global prefix for pptxgenjs.
4. pdftoppm — On Windows, install Poppler for Windows or use png output from LibreOffice directly as a fallback.
