PowerPoint Automation

AI-powered PPTX generation using Orchestrator-Workers pattern.

When to Use

• PowerPoint, PPTX, create presentation, slides
• Convert web articles/blog posts to presentations
• Translate English PPTX to Japanese
• Create presentations using custom templates

Quick Start

From Web Article:

Create a 15-slide presentation from: https://zenn.dev/example/article

From Existing PPTX:

Translate this presentation to Japanese: input/presentation.pptx

Workflow

TRIAGE → PLAN → PREPARE_TEMPLATE → EXTRACT → TRANSLATE → BUILD → REVIEW → DONE

Phase	Script/Agent	Description
EXTRACT	extract_images.py	Content → content.json
BUILD	create_from_template.py	Generate PPTX
REVIEW	PPTX Reviewer	Quality check

Key Scripts

→ references/SCRIPTS.md for complete reference

Script	Purpose
create_from_template.py	Generate PPTX from content.json (main)
reconstruct_analyzer.py	Convert PPTX → content.json
extract_images.py	Extract images from PPTX/web
validate_content.py	Validate content.json schema
validate_pptx.py	Detect text overflow

content.json (IR)

All agents communicate via this intermediate format:

{
  "slides": [
    { "type": "title", "title": "Title", "subtitle": "Sub" },
    { "type": "content", "title": "Topic", "items": ["Point 1"] }
  ]
}

→ references/schemas/content.schema.json

Templates

Template	Purpose	Layouts
assets/template.pptx	デフォルト (Japanese, 16:9)	4 layouts

template レイアウト詳細

Index	Name	Category	用途
0	タイトル スライド	title	プレゼン冒頭
1	タイトルとコンテンツ	content	標準コンテンツ
2	1_タイトルとコンテンツ	content	標準コンテンツ（別版）
3	セクション見出し	section	セクション区切り

使用例:

python scripts/create_from_template.py assets/template.pptx content.json output.pptx --config assets/template_layouts.json

テンプレート管理のベストプラクティス

複数デザイン（スライドマスター）の整理

テンプレートPPTXに複数のスライドマスターが含まれている場合、出力が不安定になることがあります。

確認方法:

python scripts/create_from_template.py assets/template.pptx --list-layouts

対処法:

1. PowerPointでテンプレートを開く
2. [表示] → [スライドマスター] を選択
3. 不要なスライドマスターを削除
4. 保存後、template_layouts.json を再生成

python scripts/analyze_template.py assets/template.pptx

content.json の階層構造

箇条書きに階層構造（インデント）を持たせる場合は items ではなく bullets 形式を使用（items はフラット表示になる）：

{"type": "content", "bullets": [
  {"text": "項目1", "level": 0},
  {"text": "詳細1", "level": 1},
  {"text": "項目2", "level": 0}
]}

Agents

→ references/agents/ for definitions

Agent	Purpose
Orchestrator	Pipeline coordination
Localizer	Translation (EN ↔ JA)
PPTX Reviewer	Final quality check

Design Principles

• SSOT: content.json is canonical
• SRP: Each agent/script has one purpose
• Fail Fast: Max 3 retries per phase
• Human in Loop: User confirms at PLAN phase

URL Format in Slides

Reference URLs must use "Title - URL" format for APPENDIX slides:

VPN Gateway の新機能 - https://learn.microsoft.com/ja-jp/azure/vpn-gateway/whats-new

→ references/content-guidelines.md for details

References

File	Content
SCRIPTS.md	Script documentation
USE_CASES.md	Workflow examples
content-guidelines.md	URL format, bullets

Technical Content Addition (Azure/MS Topics)

When adding Azure/Microsoft technical content to slides, follow the same verification workflow as QA:

Workflow

[Content Request] → [Researcher] → [Reviewer] → [PPTX Update]
                         ↓              ↓
                   Docs MCP 検索    内容検証

Required Steps

1. Research Phase: Use microsoft_docs_search / microsoft_docs_fetch to gather official information
2. Review Phase: Verify the accuracy of content before adding to slides
3. Build Phase: Update content.json and regenerate PPTX

Forbidden

• ❌ Adding technical content without MCP verification
• ❌ Skipping review for "simple additions"
• ❌ Generating PPTX while PowerPoint has the file open

File Lock Prevention

Before generating PPTX, check if the file is locked:

# Check if file is locked
$path = "path/to/file.pptx"
try { [IO.File]::OpenWrite($path).Close(); "File is writable" }
catch { "File is LOCKED - close PowerPoint first" }

Shape-based Architecture Diagrams

When creating network/architecture diagrams, use PowerPoint shapes instead of ASCII art text boxes. ASCII art is unreadable in presentation mode.

Design Pattern

from pptx.enum.shapes import MSO_SHAPE
from pptx.dml.color import RGBColor
from pptx.util import Cm, Pt

# Color scheme
AZURE_BLUE = RGBColor(0, 120, 212)
LIGHT_BLUE = RGBColor(232, 243, 255)
ONPREM_GREEN = RGBColor(16, 124, 65)
LIGHT_GREEN = RGBColor(232, 248, 237)

# Outer frame (Azure VNet)
box = slide.shapes.add_shape(MSO_SHAPE.ROUNDED_RECTANGLE, left, top, w, h)
box.fill.solid()
box.fill.fore_color.rgb = LIGHT_BLUE
box.line.color.rgb = AZURE_BLUE

# Dashed connector (tunnel)
conn = slide.shapes.add_connector(1, x1, y1, x2, y2)  # 1 = straight
conn.line.color.rgb = AZURE_BLUE
conn.line.dash_style = 2  # dash

Layout Tips

• Use Cm() for positioning (not Inches()) — easier to reason about on metric-based slides
• Leave at least 1.5cm vertical gap between Azure and on-premises zones for tunnel lines
• Place labels inside boxes (not overlapping edges) to avoid visual clutter
• Use color coding to distinguish zones: blue = Azure, green = on-premises, orange = cross-connect
• For dual diagrams (side-by-side), split slide into left/right halves with 12cm left margin for the right diagram

Anti-patterns

❌ ASCII art in textboxes (unreadable in presentation mode)
❌ Overlapping shapes due to insufficient spacing
❌ Placing labels outside their parent containers
❌ Using absolute EMU values without helper functions

Hyperlink Batch Processing

Batch-add hyperlinks and page titles to all URLs in a presentation:

Workflow

import re
url_pattern = re.compile(r'(https?://[^\s\)）]+)')

# 1. Build URL→Title map (use MCP docs_search or fetch_webpage)
URL_TITLES = {
    'https://learn.microsoft.com/.../whats-new': 'Azure VPN Gateway の新機能',
    ...
}

# 2. Iterate all runs and add hyperlinks
for slide in prs.slides:
    for shape in slide.shapes:
        if not shape.has_text_frame:
            continue
        for para in shape.text_frame.paragraphs:
            for run in para.runs:
                urls = url_pattern.findall(run.text)
                for url in urls:
                    if not (run.hyperlink and run.hyperlink.address):
                        run.hyperlink.address = url.rstrip('/')
                    # Prepend title if missing
                    title = URL_TITLES.get(url.rstrip('/'))
                    if title and title not in run.text:
                        run.text = f'{title}\n{url}'
