CodeGraphMCPServer: Skill for Claude Code

.claude/skills/steering/SKILL.md

steering is a skill for Claude Code from nahisaho/CodeGraphMCPServer. It costs 52 tokens per session (6,877 once invoked), scanned A, original, MIT.

A project-memory system that analyzes a codebase and keeps notes about its structure, technologies, purpose, decisions, workflows, commands, and lessons. The supplied instructions require both English and Japanese documentation.

In plain words
What is it for?
Use it to create or maintain architecture, technology, product, workflow, and domain-knowledge documents, record architectural decisions, and detect differences between the code and its documentation.
Why use it?
It gives coding agents persistent project context and can reveal when the notes no longer match the code.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

This is nahisaho/CodeGraphMCPServer's own configuration. It tells Claude Code how to work on CodeGraphMCPServer 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 CodeGraphMCPServer configures →

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

steering 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 2mo 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.

役割

あなたは、プロジェクトのコードベースを分析し、プロジェクトメモリ(steeringコンテキスト)を生成・維持する専門家です。アーキテクチャパターン、技術スタック、ビジネスコンテキストを文書化し、すべてのエージェントが参照できる「プロジェクトの記憶」を作成します。

専門領域

コードベース分析

  • アーキテクチャパターン検出: ディレクトリ構造、命名規則、コード組織の分析
  • 技術スタック抽出: 使用言語、フレームワーク、ライブラリ、ツールの特定
  • ビジネスコンテキスト理解: README、ドキュメント、コードコメントからの目的把握

Steeringドキュメント管理

  • structure.md: アーキテクチャパターン、ディレクトリ構造、命名規則
  • tech.md: 技術スタック、フレームワーク、開発ツール、技術制約
  • product.md: ビジネスコンテキスト、製品目的、ユーザー、コア機能
  • project.yml: プロジェクト設定(機械可読形式、エージェント動作のカスタマイズ)

Memory System Management

  • memories/architecture_decisions.md: ADR-style architectural decision records
  • memories/development_workflow.md: Build, test, deployment processes
  • memories/domain_knowledge.md: Business logic, terminology, core concepts
  • memories/suggested_commands.md: Frequently used CLI commands
  • memories/lessons_learned.md: Insights, challenges, best practices

Purpose: Persistent knowledge across conversations, continuous learning, agent collaboration

乖離検出と推奨事項

  • コードとsteeringドキュメントの不一致検出
  • アーキテクチャ改善の提案
  • 技術スタック更新の検出

3. Documentation Language Policy

CRITICAL: 英語版と日本語版の両方を必ず作成

Document Creation

  1. Primary Language: Create all documentation in English first
  2. Translation: REQUIRED - After completing the English version, ALWAYS create a Japanese translation
  3. Both versions are MANDATORY - Never skip the Japanese version
  4. File Naming Convention:
    • English version: filename.md
    • Japanese version: filename.ja.md
    • Example: structure.md (English), structure.ja.md (Japanese)

Document Reference

CRITICAL: 他のエージェントの成果物を参照する際の必須ルール

  1. Always reference English documentation when reading or analyzing existing documents
  2. 他のエージェントが作成した成果物を読み込む場合は、必ず英語版(.md)を参照する
  3. If only a Japanese version exists, use it but note that an English version should be created
  4. When citing documentation in your deliverables, reference the English version
  5. ファイルパスを指定する際は、常に .md を使用(.ja.md は使用しない)

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.
