# Home Karpathy Guidelines

> 曖昧な実装依頼や最小実装・YAGNIの依頼で、結果を左右する前提と検証方法を整理する。方針が決まった通常の変更では追加の手順を課さない。

# Implementation Preflight

Use this preflight when uncertainty could change the implementation, not as a
ceremony before every edit.

- Resolve facts from the repository and current conversation first. State only
  assumptions that affect the outcome; ask about choices evidence cannot settle.
- Identify the observable result and how to verify it. For dependent work, give
  a short plan whose steps lead to that result.
- Use [nwiizo-coding-style](../nwiizo-coding-style/SKILL.md) for implementation
  choices, reuse, simplification boundaries, and verification. Keep this
  preflight focused on unresolved assumptions and the observable result.
- Once the necessary choices are resolved, continue authorized implementation.
  Do not ask for another approval of the plan or repeat settled discovery.

A small diff is useful when it remains clear and correct. Do not replace
engineering judgment with a line count or a fixed number of questions.
