  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 7 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by minicoohei on GitHub. Read the source before you install it.

Installation

Install the Pptx Converter AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/minicoohei/ai-agent-camp/tree/main/.claude/skills/pptx-converter
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/minicoohei/ai-agent-camp.git /tmp/ai-agent-camp
mkdir -p .claude/skills
cp -r /tmp/ai-agent-camp/.claude/skills/pptx-converter .claude/skills/pptx-converter
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Pptx Converter in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Pptx Converter on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Pptx Converter is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

PPTX Converter

PowerPointファイルのテンプレート変換とゼロからのデッキ生成ツール。

機能

1. convert - テンプレート変換(1コマンド完結)

元PPTXをコピーして、全要素をGeminiで意味解析し、新トピックに合わせてコンテンツを自動書き換え。

bash
python skills/pptx-converter/scripts/pptx_converter.py convert \
    source.pptx \
    --topic "2026年Q1営業報告" \
    -o output/slides/q1_report.pptx

保持されるもの: スライドマスター、テーマカラー、フォント定義、アニメーション、トランジション、SmartArt構造、レイアウト配置

2. extract - マッピングYAML生成

元PPTXの全要素を抽出・意味解析し、座標-要素マッピングYAMLを生成。手動確認・編集用。

bash
python skills/pptx-converter/scripts/pptx_converter.py extract \
    source.pptx \
    -o mapping.yaml

3. build - マッピング + データ → PPTX

手動編集したデータYAMLで要素を書き換え。

bash
python skills/pptx-converter/scripts/pptx_converter.py build \
    source.pptx \
    mapping.yaml \
    --data data.yaml \
    -o output.pptx

4. deck - ゼロからデッキ生成

トピックからGeminiでアウトライン生成 → PPTX自動作成。

bash
python skills/pptx-converter/scripts/pptx_converter.py deck \
    --topic "AIエージェント活用提案" \
    --type proposal \
    --style corporate \
    -o output/slides/proposal.pptx

deck オプション:

  • --type: auto / presentation / proposal / report / educational / pitch
  • --style: corporate / creative / minimal / academic
  • --slides N: スライド枚数(0=AI決定)
  • --audience: 対象者
  • --outline-only: アウトラインYAMLのみ出力

What does the Pptx Converter AI skill do?

Why use Pptx Converter on TypingMind?

Because you install it once and use it with any model. Pptx Converter is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Pptx Converter in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/minicoohei/ai-agent-camp/tree/main/.claude/skills/pptx-converter. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Pptx Converter?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Pptx Converter?

As many as you like. As long as a model supports skills, you can use Pptx Converter with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Pptx Converter AI skill free?

It is published on GitHub by minicoohei. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
