mcp-gauge: Skill for Claude Code

.claude/skills/development-guidelines/SKILL.md

development-guidelines is a skill for Claude Code from sogawa-yk/mcp-gauge. It costs 57 tokens per session (1,163 once invoked), scanned A, a copy of development-guidelines, MIT.

A set of guides and templates for defining coding rules and a shared development process. It covers TypeScript and JavaScript practices, testing, Git, code review, and quality checks.

In plain words
What is it for?
Use it to create or update a project's development guidelines based on its architecture and folder structure.
Why use it?
It gives a team one agreed way to write, test, review, and organize code. This reduces inconsistent decisions and makes project work easier to follow.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

This is sogawa-yk/mcp-gauge's own configuration. It tells Claude Code how to work on mcp-gauge itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-gauge configures →

Reuse

Borrowing it

Nothing to install: this file belongs to sogawa-yk/mcp-gauge. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

development-guidelines scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to development-guidelines — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

開発ガイドラインスキル

チーム開発に必要な2つの要素をカバーします:

  1. 実装時のコーディング規約 (implementation-guide.md)
  2. 開発プロセスの標準化 (process-guide.md)

前提条件

開発ガイドライン作成を開始する前に、以下を確認してください:

推奨ドキュメント

  1. docs/architecture.md (アーキテクチャ設計書) - 技術スタックの確認
  2. docs/repository-structure.md (リポジトリ構造) - ディレクトリ構造の確認

開発ガイドラインは、プロジェクトの技術スタックとディレクトリ構造に 基づいた具体的なコーディング規約と開発プロセスを定義します。

既存ドキュメントの優先順位

重要: docs/development-guidelines.md に既存の開発ガイドラインがある場合、 以下の優先順位に従ってください:

  1. 既存の開発ガイドライン (docs/development-guidelines.md) - 最優先

    • プロジェクト固有の規約とプロセスが記載されている
    • このスキルのガイドより優先する
  2. このスキルのガイド - 参考資料

    • ./guides/implementation.md: 汎用的なコーディング規約
    • ./guides/process.md: 汎用的な開発プロセス
    • 既存ガイドラインがない場合、または補足として使用

新規作成時: このスキルのガイドとテンプレートを参照 更新時: 既存ガイドラインの構造と内容を維持しながら更新

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
