# Root Cause Challenge Pattern - 機能要求の真の動機を問う **Extracted:** 2026-02-09 **Context:** 新機能・アーキテクチャ変更・依存追加などの意思決定時 ## Problem 表面的な理由で機能追加・アーキテクチャ変更を進めると: - 真の価値を見誤る - 技術的好奇心やサンクコストに引きずられる - より高いROIの代替案を見逃す - 長期的なメンテナンス負債を作る ## Solution: 5ステップの根本原因チャレンジ ### Step 1: 論理的矛盾を探す 提案されたアーキテクチャ判断に矛盾がないかチェック: - "なぜAは却下でBは承認なのか?" - "基準は一貫しているか?" - "コスト効率は合理的か?" **例(このセッションより):** ``` Batch API: $5節約のために250行 → ❌却下 OpenAI Provider: $10活用のために750行 → ✅承認 矛盾: LOC/$ 比率が OpenAI Provider の方が悪いのに承認されている → 表面的理由($10クレジット)が本当の動機ではない可能性 ``` ### Step 2: 根本的な問いを投げる 実装方法でなく、**存在意義**を問う: - "そもそもこの機能は必要か?" - "誰が本当に求めているか?" - "解決しようとしている問題は実在するか?" - "ツールは既に動いている。これは本当に足りない機能か?" ### Step 3: Architectに忌憚ない評価を求める **重要:** 単なる実装判断でなく、**本質的価値の評価**を依頼: ```markdown ## Your Task Answer the fundamental question: Should we build this feature at all? Be brutally honest. The user wants candid feedback for growth, not validation. ### Evaluate: 1. **True ROI** - Is the return worth the investment? - Investment: Code complexity, maintenance burden - Return: Concrete value (NOT time estimates) 2. **Real motivations** - What's driving this? (be honest) - Stated reason vs actual reason - Technical curiosity? Architecture appeal? Sunk

About this skill
What does the root-cause-challenge-pattern skill do?

Use when evaluating whether a new feature, dependency, or abstraction is truly needed. 5-step root cause challenge.

How do I install it?

Run `npx skills add majiayu000/claude-skill-registry --skill root-cause-challenge-pattern --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
