  • 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.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

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

Installation

Install the Cpp Coding Standards 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.
  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.
2

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/mturac/everything-openai-codex.git /tmp/everything-openai-codex
mkdir -p .claude/skills
cp -r /tmp/everything-openai-codex/docs/ja-JP/skills/cpp-coding-standards .claude/skills/cpp-coding-standards
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Cpp Coding Standards 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 Cpp Coding Standards 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 Cpp Coding Standards 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.

C++コーディング標準(C++コアガイドライン)

C++コアガイドラインから派生した最新のC++(C++17/20/23)の包括的なコーディング標準。タイプセーフティ、リソースセーフティ、不変性、明確性を強制します。

使用時期

  • 新しいC++コードを書く(クラス、関数、テンプレート)
  • 既存のC++コードをレビューまたはリファクタリング
  • C++プロジェクトでアーキテクチャ決定を行う
  • C++コードベース全体で一貫性のあるスタイルを実施
  • 言語機能の選択(例:enum vs enum class、生ポインタ対スマートポインタ)

クロスカッティング原則

これらのテーマはガイドライン全体に繰り返され、基礎を形成:

  1. 至るところにRAII:リソースライフタイムをオブジェクトライフタイムにバインド
  2. デフォルトで不変性const/constexprで開始;変更可能性は例外
  3. タイプセーフティ:型システムを使用してコンパイル時にエラーを防止
  4. 意図を表現:名前、タイプ、概念は目的を伝える必要があります
  5. 複雑性を最小化:シンプルなコードが正しいコード
  6. 値セマンティクス対ポインタセマンティクス:値で返すか、スコープ付きオブジェクトを好む

主要なルール

RuleSummary
P.1コード内のアイデアを直接表現
P.3意図を表現
P.4理想的には、プログラムは静的にタイプセーフである必要があります
P.5ランタイムチェックに対するコンパイル時チェック
P.8リソースをリークしない
P.10変更可能なデータより不変データを好む
I.1インターフェースを明示的にする
I.2非const グローバル変数を避ける
I.4インターフェースを正確にし、強く型付けされたものにする

スマートポインタと所有権

現代的なC++では、生ポインタの代わりにスマートポインタを使用:

  • std::unique_ptr<T> 単一所有者向け
  • std::shared_ptr<T> 共有所有権向け
  • std::weak_ptr<T> 循環参照を回避するため

Frequently asked questions

Why use Cpp Coding Standards on TypingMind?

Because you install it once and use it with any model. Cpp Coding Standards 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 Cpp Coding Standards in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/mturac/everything-openai-codex/tree/main/docs/ja-JP/skills/cpp-coding-standards. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Cpp Coding Standards?

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 Cpp Coding Standards?

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

Is the Cpp Coding Standards AI skill free?

Yes. It is published on GitHub by mturac under the MIT license. 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.
