pptx 技能
L0：一句话摘要
创建、编辑和处理 PowerPoint 演示文稿（.pptx），支持模板编辑和从零创建。
L1：概述与使用场景
能力描述
pptx 是一个流程型技能（Procedural Skill），提供 PowerPoint 演示文稿的完整处理能力。支持通过 pptxgenjs（Node.js）从零创建演示文稿，通过解包 XML 编辑现有模板，以及内容提取和视觉质检。
使用场景
- 用户需要创建新的演示文稿（汇报材料、Pitch Deck 等）
- 用户需要编辑或修改现有 .pptx 文件
- 用户需要从 .pptx 文件中提取文本内容
- 用户需要将演示文稿转换为 PDF 或图片
L2：详细规范
Prerequisites
Python 3（必需 — 读取和编辑现有 PPTX 时需要）
在执行任何 Python 脚本之前，先检测 Python 是否可用：
python3 --version 2>/dev/null || python --version 2>/dev/null
如果命令失败（Python 不可用），必须停止并告知用户安装 Python 3：
- macOS:
brew install python3或从 https://www.python.org/downloads/ 下载 - Windows:
winget install Python.Python.3或从 python.org 下载（安装时勾选 "Add Python to PATH"） - Linux (Debian/Ubuntu):
sudo apt install python3 python3-pip - Linux (Fedora/RHEL):
sudo dnf install python3 python3-pip
注意：从零创建 PPTX 使用 pptxgenjs（Node.js），不需要 Python。
如需更详细的环境配置帮助，加载 environment-setup 技能。
Python 包依赖
本技能的 Python 操作依赖以下包（按需检测）：
markitdown[pptx]— PPTX 内容读取Pillow— 缩略图生成
检测方法：
python3 -c "import markitdown; import PIL" 2>/dev/null || echo "MISSING"
缺失时告知用户安装：pip install "markitdown[pptx]" Pillow
Output Rule
When you create or modify a .pptx file, you MUST tell the user the absolute path of the output file in your response. Example: "文件已保存到：/path/to/output.pptx"
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
# Text extraction
python -m markitdown presentation.pptx
# Visual overview
python scripts/thumbnail.py presentation.pptx
# Raw XML
python scripts/office/unpack.py presentation.pptx unpacked/
Editing Workflow
Read editing.md for full details.
- Analyze template with
thumbnail.py - 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.
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. If swapping your colors into a completely different presentation would still "work," you haven't made specific enough choices.
- Dominance over equality: One color should dominate (60-70% visual weight), with 1-2 supporting tones and one sharp accent. Never give all colors equal weight.
- Dark/light contrast: Dark backgrounds for title + conclusion slides, light for content ("sandwich" structure). Or commit to dark throughout for a premium feel.
- Commit to a visual motif: Pick ONE distinctive element and repeat it — rounded image frames, icons in colored circles, thick single-side borders. Carry it across every slide.
Color Palettes
Choose colors that match your topic — don't default to generic blue. Use these palettes as inspiration:
| 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) |
| Teal Trust | 028090 (teal) |
00A896 (seafoam) |
02C39A (mint) |
| Berry & Cream | 6D2E46 (berry) |
A26769 (dusty rose) |
ECE2D0 (cream) |
| Sage Calm | 84B59F (sage) |

50808E (slate) |
| Cherry Bold | 990011 (cherry) |
FCF6F5 (off-white) |
2F3C7E (navy) |
For Each Slide
Every slide needs a visual element — image, chart, icon, or shape. Text-only slides are forgettable.
Layout options:
- Two-column (text left, illustration on right)
- Icon + text rows (icon in colored circle, bold header, description below)
- 2x2 or 2x3 grid (image on one side, grid of content blocks on other)
- Half-bleed image (full left or right side) with content overlay
Data display:
- Large stat callouts (big numbers 60-72pt with small labels below)
- Comparison columns (before/after, pros/cons, side-by-side options)
- Timeline or process flow (numbered steps, arrows)
Visual polish:
- Icons in small colored circles next to section headers
- Italic accent text for key stats or taglines
Typography
Choose an interesting font pairing — don't default to Arial. Pick a header font with personality and pair it with a clean body font.
| Header Font | Body Font |
|---|---|
| Georgia | Calibri |
| Arial Black | Arial |
| Calibri | Calibri Light |
| Cambria | Calibri |
| Trebuchet MS | Calibri |
| Impact | Arial |
| Palatino | Garamond |
| Consolas | Calibri |
| Element | Size |
|---|---|
| Slide title | 36-44pt bold |
| Section header | 20-24pt bold |
| Body text | 14-16pt |
| Captions | 10-12pt muted |
Spacing
- 0.5" minimum margins
- 0.3-0.5" between content blocks
- Leave breathing room—don't fill every inch
Avoid (Common Mistakes)
- Don't repeat the same layout — vary columns, cards, and callouts across slides
- Don't center body text — left-align paragraphs and lists; center only titles
- Don't skimp on size contrast — titles need 36pt+ to stand out from 14-16pt body
- Don't default to blue — pick colors that reflect the specific topic
- Don't mix spacing randomly — choose 0.3" or 0.5" gaps and use consistently
- Don't style one slide and leave the rest plain — commit fully or keep it simple throughout
- Don't create text-only slides — add images, icons, charts, or visual elements; avoid plain title + bullets
- Don't forget text box padding — when aligning lines or shapes with text edges, set
margin: 0on the text box or offset the shape to account for padding - Don't use low-contrast elements — icons AND text need strong contrast against the background; avoid light text on light backgrounds or dark text on dark backgrounds
- NEVER use accent lines under titles — these are a hallmark of AI-generated slides; use whitespace or background color instead
QA (Required)
Assume there are problems. Your job is to find them.
Your first render is almost never correct. Approach QA as a bug hunt, not a confirmation step. If you found zero issues on first inspection, you weren't looking hard enough.
Content QA
python -m markitdown output.pptx
Check for missing content, typos, wrong order.
When using templates, check for leftover placeholder text:
python -m markitdown output.pptx | grep -iE "xxxx|lorem|ipsum|this.*(page|slide).*layout"
If grep returns results, fix them before declaring success.
Visual QA
⚠️ USE DELEGATE TOOL — even for 2-3 slides. You've been staring at the code and will see what you expect, not what's there. Delegated agents have fresh eyes.
Convert slides to images (see Converting to Images), then use this prompt:
Visually inspect these slides. Assume there are issues — find them.
Look for:
- Overlapping elements (text through shapes, lines through words, stacked elements)
- Text overflow or cut off at edges/box boundaries
- Decorative lines positioned for single-line text but title wrapped to two lines
- Source citations or footers colliding with content above
- Elements too close (< 0.3" gaps) or cards/sections nearly touching
- Uneven gaps (large empty area in one place, cramped in another)
- Insufficient margin from slide edges (< 0.5")
- Columns or similar elements not aligned consistently
- Low-contrast text (e.g., light gray text on cream-colored background)
- Low-contrast icons (e.g., dark icons on dark backgrounds without a contrasting circle)
- Text boxes too narrow causing excessive wrapping
- Leftover placeholder content
For each slide, list issues or areas of concern, even if minor.
Read and analyze these images:
1. /path/to/slide-01.jpg (Expected: [brief description])
2. /path/to/slide-02.jpg (Expected: [brief description])
Report ALL issues found, including minor ones.
Verification Loop
- Generate slides → Convert to images → Inspect
- List issues found (if none found, look again more critically)
- Fix issues
- Re-verify affected slides — one fix often creates another problem
- Repeat until a full pass reveals no new issues
Do not declare success until you've completed at least one fix-and-verify cycle.
Converting to Images
Convert presentations to individual slide images for visual inspection:
python scripts/office/soffice.py --headless --convert-to pdf output.pptx
pdftoppm -jpeg -r 150 output.pdf slide
This creates slide-01.jpg, slide-02.jpg, etc.
To re-render specific slides after fixes:
pdftoppm -jpeg -r 150 -f N -l N output.pdf slide-fixed
