powerpoint-automation is an agent skill that generates and edits PPTX from content.json, web articles, templates, and COM Automation.

About

The powerpoint-automation skill automates PPTX generation with an Orchestrator-Workers pattern using content.json as the single source of truth across extract, translate, build, and review phases. Workflow phases are TRIAGE, PLAN, PREPARE_TEMPLATE, EXTRACT, TRANSLATE, BUILD, REVIEW, and DONE. Scripts include create_from_template.py for content.json to PPTX, reconstruct_analyzer.py for PPTX back to content.json, extract_images.py, validate_content.py schema checks, and validate_pptx.py overflow validation. Quick start examples cover web article to fifteen slides, PPTX translation to Japanese, and COM Automation edits on open decks with RefURL, notes, overflow, and hyperlink verification. content.json slide types include title and content with items arrays. PPTX Reviewer handles overflow, consistency, and quality gates. License CC BY-NC-SA 4.0. Use when creating PPTX, converting articles to slides, translating presentations, editing open PowerPoint via COM, or content.json driven deck workflows. The workflow follows the source SKILL.md contract with progressive reference loading, clear trigger phrases, and practical steps developers can apply directly in agent sessions.

PowerPoint Automation

AI-powered PPTX generation using Orchestrator-Workers pattern.

When to Use

  • Web 記事やブログをスライド化したいとき
  • 既存 PPTX を翻訳・再構成したいとき
  • 開いている PPTX を COM Automation で直接編集したいとき
  • テンプレートベースで PPTX を生成したいとき
  • content.json を SSOT にして、抽出・翻訳・生成・レビューを分離したいとき

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

Edit Open PPTX with COM

Edit the currently open PowerPoint deck with COM Automation and verify RefURL, notes, overflow, and hyperlinks.

content.json

content.json はこの skill の SSOT。抽出、翻訳、生成、レビューの間は常にこれを基準にする。

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

Template

標準テンプレートは assets/template.pptx。レイアウトや用途の詳細は template 側で管理し、main SKILL には最小限だけ残す。

Operating Rules

  • SSOT: content.json を正とする
  • One phase, one purpose: 抽出・翻訳・生成・レビューを混ぜない
  • Fail fast: 問題が出たら次フェーズへ無理に進めない
  • Human in loop: PLAN でユーザー確認を入れる
  • Technical content is verified content: Azure / Microsoft の内容は MCP で一次情報確認してから入れる
  • PowerPoint lock first: 開いている PPTX に対して python-pptx で上書きしない
  • COM for open decks: 開いている PPTX や既存 deck の直接編集は references/instructions/com-automation.instructions.md を参照する
  • Operational text stays in notes: 運営メモはスライド面に出さない
  • Customer-facing surface only: 顧客向け deck のスライド面には内部向け話法、避ける表現、作業メモ、検証メモ、ファイル用途ラベルを混ぜない。話者向け情報は speaker notes へ分離する
  • Template means template: ユーザー指定テンプレートがある場合、特に表紙はテンプレートの既存プレースホルダー/レイアウトを使い、上から別図形を重ねて隠さない
  • Rendered QA before handoff: COM で開いている deck を直接 touch-up した後も、対象 deck から実レンダー画像を書き出し、重なり・フォントばらつき・表の可読性を個別 slide で確認する
  • Review like a critic, not a generator: ユーザーに見せる前に、レンダー画像で「スカスカ・文字が小さい・アイコンが雑・テンプレ踏襲不足・旧文言残り」を自分で探して直す。詳しくは references/instructions/deck-iteration-review.instructions.md
  • Media restore gate: slide insertion/deletion/recovery after a user review must re-check expected slide count and embedded video/media positions before continuing
  • Architecture diagrams use shapes: ASCII art ではなく図形で組む
  • Appendix URLs use Title - URL: 参考 URL の表示形式は統一する
  • Review content and visuals separately: 生成後は見た目レビューだけでなく、公式情報との正確性レビュー、URL hyperlink 数、notes 数、placeholder/internal wording を確認する
