Validate/update/create CLAUDE.md memory files with progressive disclosure and context-optimized structure

対話形式の質問を通じてユーザーの技術的背景、開発スタイル、AI協働の好みを把握し、最適化されたCLAUDE.mdを生成するスキル。ユーザーが「CLAUDE.mdをカスタマイズしたい」「AIの振る舞いを自分に合わせたい」「開発スタイルに合わせた設定がしたい」と言った時に使用する。新規ユーザーのオンボーディングや、既存CLAUDE.mdの見直し時にも有効。

Use when creating CLAUDE.md files, updating existing CLAUDE.md, validating CLAUDE.md structure, or auto-fixing CLAUDE.md issues. Load for setting up project instructions, global guidelines, local overrides, or modular rules. Handles global (~/.claude/CLAUDE.md), project (.claude/CLAUDE.md), local (CLAUDE.local.md), and rules (.claude/rules/*.md) with smart project detection and template generation.

This skill automatically detects when CLAUDE.md files need updates based on codebase analysis. It identifies new patterns, code violations, stale documentation, and anti-patterns, then proposes specific markdown diffs showing exactly what CLAUDE.md sections should be added, modified, or removed. When codebase architecture changes, new patterns emerge, or documented practices diverge from actual code, this skill analyzes the robo-trader project structure and generates actionable recommendation...
